 Heat Meters - RHI Renewable Heat Incentive Scheme

The Renewable Heat Incentive (RHI)

The RHI is a government established scheme that offers financial incentives to commercial and non-commercial users that are generating their own renewable heat.

The RHI scheme sets out the eligibility parameters for users wishing to claim financial incentives and the requirements of any measuring instrument that is permissible for the RHI.

MID Class 2, RHI Compliant Heat Meters

For a heat meter to be RHI permissible it must comply with class 2 accuracy ratings.

This requires the heat meter to comply with the relevant requirements set out in Annex I to the 2004 Measuring Instruments Directive (MID)2 (2004/22/EC), comply with the specific requirements listed in Annex MI-004 of the MID and fall within accuracy Class 2 as defined in Annex MI-004. 

The MID sets the requirements for a number of measuring instruments and covers heat meters. MID requirements in Annex I include allowable errors (accuracy classes), durability, resistance to disturbances, and inscriptions and markings. 

To comply with the requirements of the MID within the RHI, heat meters must comprise:

  • A flow sensor (or meter)
  • A matched pair of temperature sensors
  • A calculator/digital integrator

These components can be purchased together as an integrated heat meter or as individual components/sub-assemblies and can be brought together as part of the heat meter system.If components are brought together individually, the user must ensure they are suitable for use under the RHI. 

A heat meter that has been comprised of individual components which all meet or exceed class 2 requirements i.e class 1 would be accepted as meeting the class 2 requirements under the RHI. However if each component does not individually meet or exceed class 2 requirements then the RHI regulations are not met. 

It is the responsibility of any participants to ensure that class 2 heat meter used for RHI purposes is designed for the heat conveying liquid used by the heating system. 

Heat meters are used to measure the thermal energy provided by a source, or delivered to a use by a liquid and can be used for:

  • Heat exchangers
  • Heating systems
  • District heating
  • Chilled water
  • General HVAC applications

In order for this to be achieved a heat meter requires components that are able to measure the flow rate of the liquid and the temperature difference between the flow and return pipes.

The flow rate can be measured by a flow meter or flow sensor and the temperature difference can be measured by a pair of temperature sensors or thermocouples.

In addition to the temperature and flow sensors, a heat meter must also have a heat calculator (also known as an integrator or digital integrator).

This uses the flow rate and temperature difference measured to calculate and display the amount of heat generated or used. This is typically given in units of kilowatt-hours (kWh).

Renewable Heat Incentive (RHI)

The Renewable Heat Incentive (RHI) is the world's first long term financial support programme for renewable heat and was introduced in November 2011 for non-domestic applicants and April 2014 for domestic applicants.

The RHI scheme pays participants of the scheme that generate and use renewable energy to heat their buildings. The generation of heat from renewable sources helps to reduce greenhouse gas emissions and to meet targets for reducing the effects of climate change.

The renewable heat technologies which are eligible include: 

  • Biomass boilers
  • Ground source heat pumps
  • Water source heat pumps
  • Biomethane
  • Solar thermal hot water
  • Air to water heat pumps
  • Deep geothermal

Non-domestic applications provide payments to organisations within the industrial and public sector as well as businesses.

Domestic applications can be made by homeowners, private landlords, social landlords and self-builders.

Over a period of 20 years for non domestic buildings and 7 years domestic applications, the government (via Ofgem) will pay owners of approved systems for each kWh of heat generated according to a set of published tariffs.

Heating systems must be heat metered according to the RHI standards in order to be eligible for such payments.

The Renewable Heat Incentive (RHI) policy document sets out the detailed arrangements for this scheme, which will provide long-term financial support to renewable heat installations to encourage the uptake of renewable heat.

RHI scheme payments on renewable heat are based on heat metering however there are strict guidelines on the type of metering equipment utilised with the minimum approval requirement of MID class 2 (MI-004)

T&D are able to offer a number of RHI compliant heat meters to suit a wide range of client requirements.
