Metering | Heat Meters – Contact T&D Sales for price, delivery, support.

Thorne & Derrick are Specialist Distributors of Meters for reliable and accurate metering of Water, Gas & Heat (Thermal Energy) – we distribute heat meters (commonly referred to as Energy Meters) to meet all performance requirements involved with metering both heating or cooling circuits.

Energy efficient heat meters control and measure consumption of thermal energy with the highest levels of accuracy – measuring the physical flow of energy consumed for heating. Additional heat calculators used in conjunction with a heat metering system determine actual heat consumption for revenue billing – typical applications include heat pumps, boilers, solar energy and heating and cooling systems in industrial, commercial and domestic installations.

Heat meters typically comprise of a flow meters to measure fluid flow rate – a precise measurement of temperature between the inflow and the outflow with a means of integrating both measurements over a time period.

SELECTING YOUR HEAT METER

In order to select the most suitable heat meter for your application we require:

  • Pipe size (nominal diameter and material)
  • Minimum and maximum flow rate
  • Maximum working pressure
  • Heating or cooling application. If cooling please confirm glycol type and concentration
  • Mains or battery powered
  • Communication type preferred: Mbus/Modbus/radio/wireless/other
  • Scheme regulation conformance: RHI MID Class 2/other

Heat Meters & the rhi – Renewable Heat Incentive

The non-domestic Renewable Heat Incentive is a government scheme providing financial incentives to industrial, commercial and public sector organisations that are generating their own renewable heat – the RHI scheme was set up to replace the Low Carbon Building Programme which ended in 2010.

The RHI Scheme operates a feed-in tariff where users get paid when they install an electricity generating technology from a renewable or low-carbon source and was introduced in the Energy Act 2008. Typical installations that require heat metering include biogas, solid biomass boilers, deep geothermal and ground source heat pumps (GSHP).

RHI The Renewable Heat Incentive Scheme

The Renewable Heat Incentive Scheme

The RHI scheme has been developed in order to encourage users to develop their own heat from a renewable source rather than relying on fossil fuels. The scheme is implemented and administered by Ofgem on behalf of the Department For Energy And Climate Change.

The RHI scheme is open to the non-domestic sector including industrial, commercial, public sector and not-for-profit organisations with eligible installations. A non-domestic installation is classified as a renewable heat unit that supplies large scale industrial heat.

Video –  tHE rhi & Heat Metering

This video features Kamstrup evaluating how a heat meter operates, how they should be applied in the installation and what supplementary certification should be made available with them for RHI approval and purposes.

When installing a heat meter, there are specific criteria that must be met in order to claim under the RHI scheme considering the types of heat meter and their installation. The points that must be followed when installing a heat meter are:

        • Positioning
        • Calibration and Accuracy
        • Suitability (e.g. is the heat meter set up correctly for the liquid in the system)
        • Installation (meters must be installed in line with manufacturer’s instructions and appropriate for the system they are monitoring, e.g. flow rates)

In addition to the installation criteria, heat meters for the non-domestic RHI scheme must also be MID class 2 approved to guarantee their measurement accuracy.
