4.6.6 Meter Installations
The government is introducing the Renewable Heat Incentive (RHI) to support renewable heat generation
in the domestic sector. The scheme will offer tariff payments for supported technologies which include
MCS (or equivalent)
-
certified solar thermal systems, ground source heat pumps, air source heat pumps
and biomass boilers or stoves with back boilers for use in the domestic sector.
All RHI installations should be made meter
-
ready. In addition, in some cases, applicants will require
metering for payment in order for their systems to be RHI
-
compliant, whilst in other cases, applicants
could be paid extra for monitoring of system performance.
MCS guidelines make three distinct types of meter installation
Meter
-
ready
-
All RHI installations should be meter
-
ready for BEIS
’
s own metering to be fitted to
the site if selected.
Metering for payment
-
Where a heat pump or biomass boiler is installed alongside certain other
heating systems or where the installer is advised that the property is a second home, then the
renewable heating system shall be metered in order to receive payment under the RHI.
Metering and Monitoring Service Packages
-
A Customer may install an optional metering and
monitoring service package for either a pellet biomass boiler or a heat pump for which they will
receive a financial uplift. The specifications for installation of meters as part of these packages are
detailed in this section along with any other requirements in order for the package to be installed
in a form that is compliant with the RHI.
For information on Metering for payment and Metering and Monitoring Service Packages it is
recommended that the MCS document
MCS Domestic RHI Metering Guidance V1.0
is consulted. The
section below covers
‘
meter ready
’
installations only.
4.6.6.1 Meter Ready Installations
Some installations incentivised through the RHI will have BEIS
’
s own metering fitted where the metering
data may then be used to allow BEIS to evaluate the effectiveness of the policy and data may be shared
with MCS.
BEIS intends to install meters to monitor the heat output from a renewable heating system, the energy
consumed by those same heat sources, and the heat output from any back
-
up fossil fuel systems. This
could require engineers, appointed by BEIS, to install a number of heat meters, electricity meters or other
energy meters, depending on the specific heating system and manner of installation. In addition, BEIS will
install a number of temperature sensors to develop an understanding of the behaviour of a range of
heating systems, for example temperature measurement of space heating flow and domestic hot water
flow. The sensor outputs will be connected to a logger that will store all readings and regularly transmit
them to a centralized secure data source.
All RHI
-
compliant renewable heating installations should be made meter
-
ready. Installers should:
1)
Leave sufficient space for appropriate meters to be fitted in defined locations; Heat pumps
The flow meter and return temperature sensor of the heat meter(s) take up the most space and
need to be situated on the return pipework between the circulation pump and the distribution
system. The required length of straight pipework between isolation valves is 20 times the pipe
