Micro-Cogeneration Add-On-Test Package: Test methodology based on PAS 67:2013 Version: v1.0

1. INTRODUCTION The current PAS 67:2013 specifies the laboratory tests to determine the heating and electrical performance of heat-led micro-cogeneration

packages primarily intended for heating dwellings. However it does not cover testing of micro-cogeneration unit (MCU) or add-on package (MCP)

incorporating a micro-cogeneration unit designed for integrating with the existing heating or hot water systems in buildings.

This document described the test methodology and the application of test data for installing the Add-on micro-cogeneration unit or package.

The testing of the Add-on MCP/MCU is based on established procedures defined in PAS67: 2013 with additional measurements to quantify the

performance of the Add-on package when it is tested with the reference heat source. The test results are normalised using the Micro-

Cogeneration Add-On Calculator for generating installation performance data e.g. by using the APM calculator or SBEM for non-domestic

buildings.

A hypothetical Add-on MCP was used to test and validate the proposed test and application procedures. The performance of tis example Add-on

MCP was modelled as an integrated unit including the supplementary boiler. The data was then transferred to the APM calculator to calculate

base level results (Section 2.5) for comparison. The example was then modelled as an Add-on MCP with 30kW reference test boiler and

performance results were calculated and compared with an integrated MCP variant example (Sections 3 & 4).

The comparison of the current certification and application procedures for the integrated MCP and the proposed procedure for the Add-on

Micro-cogeneration unit/package are shown in figure 1.1. As shown in this figure, the certification and the application procedures for both Add-

on MCP and an integrated MCP are similar. The Micro-Cogeneration Add-On Calculator also compares the CO2 emissions of the Add-On MCP

heating system with equivalent conventional gas heating system at the reference space and hot water heating test condition.

2. PAS 67:2013 STANDARD - OVERVIEW

2.1. MICRO-COGENERATION PACKAGE CATEGORIES The micro-cogeneration packages covered by the PAS 67:2013 standard are defined below in table 2.1.

Table 1.1: Generic categories of Micro-cogeneration packages

Type Description

RegPK Package for provision of space and hot water heating with storage (>15L) based hot water heating and hot water store may not be part of the package.

CombiPK Package for provision of space and hot water heating with storage capacity less than 15L i.e. the packaged system acting as a combination boiler

HeatPK Package for the provision of space heating only

2.2. THE OPERATING TEST MODES COVERED BY THE STANDARD The MCP operating test regimes used for testing the package depends upon the generic category of the Micro-Cogeneration package and the

operating mode specified by the manufacturer. The standard and optional performance test are summarised below in table 2.2.

NOTES ON TEST MODES [1] The standby losses are always measured for all package types using the standby mode defined in clause 12.6). [2] If required by the manufacturer, the performance of the package can be evaluated at other heating output fractions. [3] The performance of the package (Type CombiPK & RegPK) is not measured with combined space and hot water heating loads [4] The test regime 5 is for Add-on MCP designed to heat domestic hot water only i.e. type DHWPK

2.3. MAIN PARAMETERS MEASURED DURING PERFORMANCE TESTING OF MCP The main parameters measured during performance testing of MCP to PAS 67:2013 will depend upon the package type. The main parameters

measured for a generic space and hot water heating packages (RegPK, CombiPK) are shown schematically in figure 2.1 and for a hot water only

heating package (DHWPK) are shown in figure 2.2.

The test method does not require independent measurements of fuel consumptions and thermal outputs of the prime mover and the

supplementary heat source (e.g. a boiler) if it is present in the Micro-cogeneration package (MCP). This because it is assumed that the MCP will

replace the existing space heating and/or hot water heating heat source in the building.


2.4. PAS 67: 2013 TEST RESULTS AND APPLICATIONS

2.4.1. SINGLE-FAMILY DWELLINGS

The Annual Performance Method (APM) calculator is used for calculating the performance of the MCP in single-family dwellings. This calculator

takes into account the plant size ratio, heat loss etc. The MCS performance test results required for the APM calculator are shown in table 2.3

(Subset of a table in PAS 67:2013). The APM calculator generates the data listed below for heating loads ranging from 0% to 100% and plant

size ratio ranging from 0.5 to 10.0 for the ‘Products Characteristics Data Base’ which then used in SAP 2013 for calculating the energy and

environmental ratings of the building in in which the MCP is installed.

The APM output results are also used in MCS 014 to produce the HPER values (kgCO2/kWh) for plant size ratios between 0.5 and 4.0. A MCP

qualifies for the micro-cogeneration MCS “Installation Standard MIS 3007” for all plant size ratio where the HPER is ≤ 0.230 kgCO2/kWh.


One of the basic assumptions made in APM calculator is that the declared maximum thermal output of the package is independent of the dwelling

and it is primarily designed to replace the main heat source supply space and/or hot water heating in a building. Therefore if the package is

installed in low heat loss dwelling, its annual average load factor will be lower and visa versa

Summary of performance data produced by APM calculator

a) Gross thermal efficiency for space heating (%)

b) Gross thermal efficiency for hot water heating (%)

c) Electricity consumed for space heating (kWhe per kWhh). This value will be negative for MCP

d) Electricity consumed for hot water heating (kWhe per kWhh). This value will be negative for MCP

2.4.2. COMMERCIAL AND MULTI-FAMILY DWELLINGS

For non-domestic buildings, the Simplified Building Energy Model (SBEM) is used analysing the performance of MCP based on the PAS67:

2013 test data. This software tool generally used: -

a) To determine CO2 emission rates for new buildings in compliance with Part L of the Building Regulations (England & Wales) and

equivalent regulations in Scotland and Northern Ireland.

b) In support of the National Calculation Methodology (NCM) and the Energy Performance of Buildings Directive (EPBD).

2.5. PERFORMANCE RESULTS OF A HYPOTHETICAL INTEGRATED MCP A hypothetical integrated mCHP package consisting of a prime mover, auxiliary gas boiler and hot water storage vessel has been used in this

document to demonstrate the testing and the data analysis procedures and for generating PAS 67:2013 test results for an Add-on MCP package

coupled to a reference example 30kW test boiler. The key calculated results for this example integrated MCP are shown below in table 2.4.

These results were then used to calculate the performance of the system using the “PAS67 APM (rev 4e V5.05)” calculator and the selected APM

output results are shown in table 2.5 and figure 2.3. These results were used to validate the test and scaling procedures for Add-on MCP in the

Micro-Cogeneration Add-On Calculator.

3. ADD-ON MICRO-COGENERATION PACKAGE AND TEST PROCEDURE

3.1. DESCRIPTION The add-on micro-cogeneration Package i.e. “Add-on MCP” is primarily designed to integrate with the existing space and/or hot water heating

systems in a domestic and commercial buildings and to use the existing main heat source (e.g. a gas boiler) to supplement the heat produced by

the prime mover in the Add-on MCP if and when required. The main components of the Add-on MCP are listed below and typical examples of

test configurations for different types of Add-on MCP are described and shown in the following sections.

a) Prime mover mCHP appliance (e.g. Fuel Cell, ICE).

b) Control and hydraulic packages for integrating with existing system.

c) Domestic hot water cylinder or an integrated thermal store (If these are part of the part of the Add-on package).

d) Installation and operating instructions.

3.1.1. ADD-ON MCP FOR SPACE AND HOT WATER HEATING

The schematic diagram of an Add-on MCP shown in figure 3.1 contains of a prime mover, controls package and a hydraulic interlace unit (e.g.

control valve, headers etc.). This is designed to connect to the existing heating and hot water system using hydraulics interface and controls

only. The existing boiler, radiator circuit and the hot water cylinder [1] are connected to the hydraulic interface unit. For the reference testing,

the manufacturer would specify the external hot water cylinder for the RegPK types of Add-on MCP, which is designed to provide both space

and hot water heating.

The hot water cylinder is not required for the CombiPK type of Add-on MCP because, the domestic hot water service is provided wholly from

within the package supplied for testing.

Add-on MCP type shown schematically in figure 3.2 contains a thermal energy store (TES) as part of the package. In this example the existing

boiler and heating circuit in the building are connected to the TES and it also provides domestic hot water. Therefore the existing hot water

cylinder in the building (if present) will normally be removed.

NOTES

[1] It is likely that the DHW only systems will be suitable for range of different external cylinder sizes. The cylinder size can influence the type of

tapping cycle that can be achieved with the combination of Add-On MCP and the external heat source. Therefore reference testing of the DHW

only Add-On MCP with the smallest recommended external cylinder should be considered.

3.1.2. ADD-ON MCP FOR SPACE HEATING ONLY

The HeatPK type of Add-on MCP designed for space heating only is shown schematically in figure 3.3. It contains of a prime mover, controls

package and a hydraulic interlace unit (e.g. control valve, headers etc.). This is designed to connect to the existing space heating system using

hydraulics interface and controls only. The existing boiler and the radiator circuit are connected to the hydraulic interface unit.

Add-on MCP designed for space heating only shown in figure 3.2b contains a thermal energy store (TES) as part of the package. The TES stores

the heat from the boiler and the prime mover, which then used for space heating. In this example add-on MCP, the existing boiler and heating

circuit in the building are connected to the TES.

3.1.3. ADD-ON MCP FOR HOT WATER (DHW) HEATING ONLY

An example of the Add-on MCP designed for domestic hot water heating only, shown schematically in figure 3.5 requires supplementary boiler

to help meet the hot water load in the building. This approach supports both heat and electric lead systems. It contains of a prime mover, controls

package and a hydraulic interlace unit (e.g. control valve, headers etc.). The existing boiler and the hot water cylinder [1] are connected to the

hydraulic interface unit. For reference testing, the manufacturer would specify the hot water cylinder and the reference test boiler.

An example of the stand-alone Add-on MCP designed for DHW heating only shown in figure 3.6 does not require supplementary boiler for

reference testing for the reasons listed below. For reference testing, the manufacturer would specify the hot water cylinder only and specify how

the package will be integrated onsite.

a) Either its thermal output under the design operating conditions meets the hot water load in the target building without any

supplementary heat input in which case it can only be classed as heat led.

b) Or it is used to provide a preheated domestic hot water to the main hot water heating system in the building as shown schematically

in figure 3.6 [2].

NOTES

[1] It is likely that the DHW only systems will be suitable for range of different external cylinder sizes. The cylinder size can influence the type of

tapping cycle that can be achieved with the combination of Add-On MCP and the external heat source. Therefore reference testing of the DHW

only Add-On MCP with the smallest recommended external cylinder should be considered.

[2] This type of Add-on MCP should be installed in in such a way that its operation is independent of the operation of the main hot water heating

source in which case it can only be classed as heat led.

3.2. PROPOSED PAS 67:2013 TEST METHOD FOR ADD-ON MCP

3.2.1. KEY REQUIREMENTS OF TEST METHODOLOGY

The performance test modes and the test regimes defined in the current PAS 67:2013 will be used for evaluating the performance of the Add-on

MCP using the reference supplementary heat source and other equipment specified by the manufacturer. The test methodology described in this

document was selected because it met the following key requirements: -

a) On of the main objective of the Add-on MCP is to maximise the utilisation of the prime mover when it is integrated with the existing

heating system in the building. Therefore the test method should be capable of discriminating between a good and a poor performing

Add-on MCP as discussed below in section 3.2.2.

b) The performance of the reference Add-on MCP system measured in the laboratory, should be scalable to a range of buildings and

heating system sizes (i.e. Design heat loads and plant size ratios) within the predefined limits without retesting.

c) The current PAS 67:2013 test methodology should be used with minimum changes. However some additional measurements may be

necessary.

d) The test results should be suitable for using the existing performance analysis calculators for both domestic and non-domestic

buildings e.g. PAS67 APM (rev 4e V5.05) for domestic buildings and for MCS 014 and MCS 015.

3.2.2. PRIME MOVER AND SUPPLEMENTARY HEAT SOURCE INTEGRATION

As shown schematically in figures 3.1 and 3.2, the Add-on MCP incorporating the prime mover (e.g. Fuel cell, ICE) and the supplementary heat

source (e.g. existing gas boiler) in the building are integrated onsite using controls and hydraulic integration packages supplied by the

manufacturer. The performance of the system therefore will depend upon the integration efficiency, load factor and plant size ratio etc.

The effect of system integration efficiency i.e.

installation of the Add-on MCP in a building and

integrating it with the existing heating system is

illustrated in figure 3.7.

Generally, the thermal output of the boiler will

be significantly higher than the thermal output

of the prime mover (Factor >5). Therefore if the

integration is inefficient e.g. the prime mover is

not the lead heat source, then the heat supplied

by the prime mover will not significantly change

with demand because the boiler will supply

most of the heat demand.

If the integration is efficient i.e. the prime mover

is always acting, as the lead heat source with

intelligent demand management then the heat

supplied by the prime mover will increase as the

heating load decreases resulting in increased

run hours for the prime mover.

3.2.3. TEST METHODOLOGY FOR THE ADD-ON MCP/MCU - GENERAL

a) All types of Add-on MCP/MCU should be tested as a complete package that is going to be supplied, installed and integrated with the

existing heating systems in buildings. The package (e.g. Prime mover, controls, hydraulics assembly, hot water vessel) should be

installed and operated in the laboratory as per manufacturer’s instructions.

b) The RegPK, HeatPK and CombiPK types of Add-on MCP/MCU should only be tested with a reference supplementary heat source e.g. a

gas boiler [1] specified by the manufacturer.

c) The DHWPK types of Add-on MCP designed for hot water heating only can be tested as follows configurations: -

1) If the DHWPK Add-on MCP designed to supply domestic hot water directly to the hot water outlets in the building and it requires

a supplementary boiler to help meet the hot water load in the building, then it should be tested with specified reference boiler.

The schematic diagram of this type of DHWPK Add-on MCP is shown in figure 3.5.

2) If the DHWPK is designed to supply domestic hot water to a hot water storage vessel in the building then it should be tested in

stand-alone mode without the reference test boiler. The stand-alone DHWPK may have a intermediate hot water storage vessel

as part of the Add-on MCP. The schematic diagram of stand-alone DHWPK Add-on MCP is shown in figure 3.6.

d) For reference testing the space heating power at 100% load factor should be within 10% of the rated output of the reference test boiler

at 80oC flow and 60oC return temperatures [2].

e) The generic configuration for reference testing the Add-on MCP system is shown in figure 3.8. In addition to the standard PAS 67:2013

performance measurements, the following additional measurements should be made: -

1) Fuel energy used by reference boiler (QF_RBLR)

2) Electrical energy used by reference boiler (QE_RBLR)

3) Flue losses from reference boiler (QL_FLUE_RBLR) for energy balance checks

4) Heat supplied by the reference boiler to Add-on MCP. This will allow the performance of the system to be calculated with different

efficiency band power rating of boilers.

In practice separate measurements of both reference boiler and the Add-On MCP heat inputs, flue CO2, flue condensate

production rates etc. are required. As a consequence it becomes harder, especially at part load tests, to satisfy the energy balance

limits set in the PAS 67:2013. Therefore it is recommended that new wider acceptable limits should be set which override those

set in PAS 67:2013.

NOTES

[1] In this document a 30kW-condensing boiler is used for calculating the performance of the reference test system as an example only to

illustrate the test methodology.

[2] Different heating flow and return temperatures may be used, provided these meet the relevant requirements of PAS 67:2013.

[3] The schematic diagrams 3.2, 3.4 and 3.6 shows hot water vessel as part of the Add-on MCP. However this may not always be the case and

is not a requirement. However the cylinder size can influence the type of tapping cycle that can be achieved with the combination of Add-

On MCP and the external heat source. Therefore reference testing of the DHW performance with the smallest recommended external

cylinder should be considered.

3.2.4. DHW TESTS FOR THE ADD-ON MCP/MCU

a) DHW performance test [1] should be carried out as per PAS67: 2013 at the hot water tapping cycle specified by the manufacturer for

Add-on MCP types RegPK, CombiPK and DHWPK.

b) DHW performance testing is not required for Add-on MCP designed for space heating only i.e. type HeatPK.

NOTES

[1] Depending upon the performance characteristics of the Add-on MCP/MCU, DHW performance tests at more than one hot water tapping

cycles should be considered.

3.2.5. SPACE HEATING TESTS FOR THE ADD-ON MCP/MCU

a) The space heating performance tests should be carried out as per PAS67: 2013 for Add-on MCP types RegPK, CombiPK and HeatPK

using 100% heating load, operating mode and control settings specified by the manufacturer,

b) The load PAS67: 2013 specifies that space heating performance tests should be carried out at least at 100%, 30% and 10% load factors.

Depending upon the performance characteristics of the Add-on MCP/MCU (see figure 3.7), space heating performance tests at

intermediate load factor should be considered. This will enable the APM calculator to predict the performance of the Add-on MCP more

accurately for installation dwellings. The permitted supplementary heat load tests depend upon the test regimes specified and are

listed in table 2.2.

c) If the maximum thermal output of the Add-on MCP is less than or 10% of the space heating demand of the building, then space heating

test at 100% load factor only should be carried out. The calculation procedure is shown below for an example Add-on MCP.

Example calculation:

Maximum thermal rating of the add-on MCP = 1.0kW

Space heating operating mode: Bi-Modal

Space heating on time = 11 h/day

Heating season = 220 days/year

Maximum heat output from Add-on MCP (QTMCP) = 220 x 11 x 1.0

= 2,420 kWh/year

Space heating demand of the building (QTBUILDING) = 26,500 kWh/y

QTR = QTMCP x 100/QTBUILDING = 2,420 x 100/25,500

= 9.13%

QTR < 10%, therefore only testing at 100% load factor is required.

3.3. PERFORMANCE AND SPECIFICATION OF THE EXAMPLE ADD-ON MCP The main performance specification of the hypothetical example Add-on MCP used for validating and describing the testing, data normalising

and scaling procedures is presented in appendix 1. The calculated performance of this system is summarised in table 3.1 and the main

performance parameters required for scaling the measured data for range of dwellings are shown in figure 3.9. The scaling procedure is specified

in the Micro-Cogeneration Add-On Calculator and in appendix 2. This calculator generates the data, which can be further processed by the

standard APM calculator for the Product Characteristic Database and for the MCS micro-cogeneration standards.

4. MICRO-COGENERATION ADD-ON CALCULATOR

4.1. OVERVIEW The excel workbook based “Micro-Cogeneration Add-On Calculator” has multiple input and output sheets which are described below in

section2. This calculator is an interface between the PAS 67:2013 performance test results and the current tools for demonstrating compliance

with the relevant building regulations. The overview of the process is shown in figure 4.1. The Micro-Cogeneration Add-On Calculator is used to

process the PAS 67:2013 performance data measured with reference supplementary boiler to generate following parameters: -

a) Thermal and environmental performance of the Add-on MCP heating system when coupled to a supplementary boiler of different power

rating and efficiency (within the pre-set boundary limits) in the installation building.

b) The scaled pace and/or hot water heating performance data is normalised so that it can be linked to either the APM calculator for domestic

buildings or the SEBM tool for non-domestic building.

c) Generate performance tables including pass/fail boundaries for the product literature so that the installers can use it to demonstrate

compliance with the relevant Building Regulations and standards. (Note: This will be implemented after this methodology has been accepted

by BRE).

Add-on MCP performance tests

a) With specified reference boiler specified by the manufacturer b) Using operating mode and regimes specified by the manufacturer

c) Test system set up as per manufacturers design and installation manuals

d) Tests to be carried out relevant sections of Pas 67:2013 with additional measurements

4.2.3. TAB/SHEET ‘Installation Package’

This is the main calculator for scaling and normalising the Add-on MCP performance results measured with the reference boiler. The key for the

data entry in the cells is: -




Red font: Calculated values and cannot be overwritten

The methodology used for scaling the reference test results to the system in the installation dwelling is described in this document as “Micro-

Cogeneration Add-On Calculator Algorithms” and summarised in appendix 2. These algorithms are embedded in the hidden calculating tables in

this sheet and are based on the key assumptions listed in section 4.2.3.1.

4.2.3.1. Assumptions

a) General

The space heating flow and return temperatures for the installation system are the same as the reference test boiler.

The heating operating mode (e.g. continuous, bimodal etc.) is same the reference test system.

The system control logic and controls for optimizing the operation of the prime mover in the Add-On MCP are same.

The modulation band of the new boiler is similar to that of the reference boiler.

b) Standby performance

Standby performance of the Add-On-MCP is independent of the size and type of the building and the thermal output rating of the

supplementary boiler.

The supplementary boiler will be off during the standby-operating mode of the system. Therefore only the standby power

consumption of the installation boiler will affect the standby heat loss tests carried out with the reference boiler.

c) DHW heating performance

It is assumed that the control logic, control parameters and the controls used in the installation system are same as those used in

reference PAS 67 DHW heating tests.

The DHW heating performance the system in the installation dwelling will depend upon the hot water heating load.

The methodology used for calculating the hot water heating performance depends upon the number of reference DHW heating tests

carried out (e.g. Tapping cycles: 0, 1, 2 or 3) and this is specified in appendix 1.

d) Space heating performance

It is assumed that the control logic, control parameters and the controls used in the installation system are same as those used in

reference PAS 67 DHW heating tests.

Although the space heating thermal energy supplied by the Add-On-MCP and its performance will not significantly change when the

boiler in the installation building replaces the reference test boiler, it will change with the design heat loss of the building.

The electricity produced by the Add-On-MCP when in space heating mode will depend upon the thermal load but will not be

significantly affected when the installation boiler replaces the reference test boiler.

The electricity consumed by the installation boiler system will depend upon the standby power consumption and this has been taken

into account in the calculating procedures.

The methodology used for calculating the space heating performance depends upon the number of reference heating tests carried out

and this is specified below.

4.2.3.2. Table IS_01

The main parameters of the installation building and the heating system are specified in this table. The boundary conditions are pre-set and

depend upon the rating of the reference test boiler and design heat loss of the building.

4.2.3.3. Table IS_02

The hot water heating system in the installation building is specified in this table. The heating load can be specified in either as daily hot water

consumption (L/day) or as one of the standard EU tapping cycle e.g. XL.

4.2.3.4. Tables IS_03, IS_04 and IS_05

These tables contain the calculated heating, DHW heating and standby performance results for the Add-on MCP heating system in the selected

dwelling. These tables also show the emissions for a equivalent conventional gas heating system. The values are automatically loaded into these

table from the hidden calculating tables in this sheet and therefore no user input is required in these tables.

4.2.3.5. Table IS_06

The calculated results are summarised in table IS_06 in the format required for the APM calculator. The cells in this table can be directly linked

to the appropriate tables in the APM calculator for generating energy and environmental performance data as shown below for the example

system.

6.1. STANDBY PERFORMANCE CALCULATIONS

6.1.1. ASSUMPTIONS

a) Standby performance of the Add-On-MCP is independent of the size and type of the building and the thermal output rating of the

supplementary boiler.

b) The supplementary boiler will be off during the standby-operating mode of the system. Therefore only the standby power consumption of

the installation boiler will affect the standby heat loss tests carried out with the reference boiler.

6.1.2. CALCULATION PROCEDURE

The following procedure has been used for transposing the reference test result to the installation system.

QF(IS)_AMCP = QF(RS)_AMCP ----- (1) QF(IS)_BLR = QF(RS)_BLR ----- (2) QF(IS)_TOT = QF(IS)_AMCP + QF(IS)_BLR ----- (3) QE(IS)_AMCP_OUT = QE(RS)_AMCP_OUT ----- (4) QE(IS)_AMCP_IN = QE(RS)_AMCP_IN ----- (5) QE(IS)_BLR = QE(RS)_BLR x (SP_IB/SP_RB) ----- (6) QE(IS)_NET = QE(IS)_AMCP_OUT - QE(IS)_AMCP_IN - QE(IS)_BLR ----- (7) Where: QF(IS)_AMCP = Calculated fuel energy used by Add-On-MCP in standby mode in the installation building QF(RS)_AMCP = Measured fuel energy used by Add-On-MCP in standby mode during reference testing QF(IS)_BLR = Calculated fuel energy used by the boiler in standby mode in the installation building QF(RS)_BLR = Measured fuel energy used by the reference boiler in standby mode during reference testing QF(IS)_TOT = Total calculated fuel energy used by the heating system in the installation building QE(IS)_AMCP_OUT = Calculated electrical energy produced by Add-On-MCP in standby mode in the installation building QE(RS)_AMCP_OUT = Measured electrical energy produced by Add-On-MCP in standby mode during reference testing QE(IS)_AMCP_IN = Calculated electrical energy used by the Add-On-MCP in standby mode in the installation building QE(RS)_AMCP_IN = Measured electrical energy used by the Add-On-MCP in standby mode during reference testing QE(IS)_BLR = Calculated electrical energy used by the boiler system in standby mode in the installation building QE(RS)_BLR = Measured electrical energy used by the reference boiler system in standby mode during reference testing SP_IB = Declared standby electrical energy consumption of the boiler system in installation building SP_RB = Declared standby electrical energy consumption of the reference boiler system used in reference testing QE(IS)_NET = Calculated net electrical energy exported by the Add-On-MCP system in the installation dwelling
