The Sontex Brand

Established 26 years ago in 1989, Sontex heat meters are developed and manufactured using the most modern technology.

Synonymous with innovation, Sontex heat meters have been developed to serve thermal energy measurement, heating and cooling systems and consumption data collection. 

Sontex is active globally with over 100 highly active, specialised employees. Thorne & Derrick are major distributors for the full range of Sontex Heat Meters.

Sontex Heat Meters - Renewable Heat Incentive (RHI) Compliant 

The Renewable Heat Incentive (RHI) is a government backed scheme and is the worlds first long term financial support programme based around renewable heat. Under the RHI, participants will be paid for all renewable heat that they use and generate.

The RHI is intended to increase the generation of renewable heat rather than relying on fossil fuels. This will not only reduce greenhouse gas emissions but will also help the UK meet targets for reducing the effects of climate change. 

Renwable Heat Incentive (RHI)

Within the scheme, Ofgem is responsible for the implementation and administering the scheme on behalf of the Department of Energy and Climate Change

Sontex’s 2000 m² manufacturing area is equipped with the latest infrastructure to produce and to test heat meters, temperature sensors, heat cost allocators and suitable communication systems.

Eligibility & How To Claim From The Non-Domestic RHI

To be able to take part in the non-domestic Renewable Heat Incentive, you must be able to demonstrate that your installation meets the all of the eligibility criteria. The general eligibility checklist is as follows: 

  • The applicant must be the owner of the installation and must have had their identity and bank details verified. If there are multiple owners, the applicant must have the permission to act on behalf of the others
  • The plant must be an eligible renewable heat technology type and size
  • The plant must have been commissioned on or after 15 July 2009 and the following installation completed:
    • Geothermal
    • Solar collectors
    • Energy from Waste
    • Ground and Water Source Heat pumps
    • Biogas below 200kWth
    • ​Solid Biomass
  • The following technologies must have been commissioned on or after 4 December 2013
    • Air to Water Heat Pumps
    • Biogas 200kWth and above
    • A CHP system which generates heat from either solid biomass, biogas or waste in combination with any other source of energy

To apply for the non-domestic RHI, the following steps will act as a guide:

Step 1: Gather your documentation - This involves answering questions about your installation and providing the relevant evidence

Step 2: Create and order on the Non-domestic RHI register - Follow the RHI register on-screen instructions. To do this you need to be the authorised signatory for your organsiation

Step 3: Complete the application form - Once logged into the non-domestic RHI register you can access the application via the Accreditation tab

Step 4: Upload Evidence - Once the form is completed, you will be directed to the upload section to upload your evidence in PDF format. Everyone is required to upload the following evidence:

  • Commissioning certificate or commissioning report for the installation

  • Schematic diagram of the installation

  • Photo of meter(s), clearly showing the serial number and MID/Class 2 markings

  • Letter of authorisation that confirms your organisation’s Authorised Signatory for its RHI account

  • Photo of the nameplate of the installation clearly showing the capacity and serial number

  • For heat pump installations, evidence of Coefficient of Performance COP (Technical) is required

  • Evidence of non-single domestic status. This could be multiple council tax bills or a business rates bill

  • An Independent Report on Metering Arrangements (IRMA)

Step 5: Verify bank details and identity - Unlike other forms that are uploaded on the RHI register, you will need to post identification documents and bank details.

RHI On-Going Responsibilities

Once your RHI accreditation has been received, that is only the start. There are a number of on-going responsibilities to ensure you continue to comply for the RHI:

  • Taking meter readings and submitting heat data
  • Regular maintenance of heat meters and equipment in-line with the manufacturer instructions. It is also important to keep a record of the maintenance schedule
  • For any biomass heating systems, it is important to keep a log of quantity of fuel used. 
  • Keeping service and fuel receipts
  • Reporting any significant changes to the installation or your heat usage
  • Submitting an annual declaration that confirms your compliance with your obligations

Any users participating in the scheme can be selected for an audit or site inspection at any time.

About Our Range Of RHI Heat Meters

Thorne & Derrick offer a wide range of RHI compliant MID class 2 heat meters. 

Most Sontex heat meters are approved to EN 1434 and MID class 2 ; these approvals guarantee conformance to installation, operating monitoring and maintenance and also allows these to be utilised for the RHI scheme. The Supercal 539 is not RHI compliant as this product only meets MID class 3 requirements.

T&D can offer the full of Sontex RHI compliant heat meters including the Supercal 531, Supercal 539 and the Superstatic 440, 449 & 749.

Sontex Heat Meters - Suitable for Renewable Heat Incentive Applications

Sontex Heat Meter - Supercal 531 

The Sontex Supercal 531 heat meter provides a high level of flexibility and has a modular design.

Suitable for heat, cooling and combined heating and cooling energy and flow measurement, the Supercal 531 is ideal for district heating networks and heat cost allocation requirements in industrial applications. 

The Sontex Supercal 531 is RHI, MID Class 2 approved to EN1434 allowing the meter to be used within applications under the renewable heat incentive.

Sontex Heat Meter - Supercal 539 

The Supercal 539 is a compact universal heat meter which is battery operated and can be integrated into existing systems via two additional pulse inputs (optional) to connect flow meters.

The Supercal 539 is MID Class 3 approved and therefore is not suitable for RHI applications.

Sontex Flow Meter - Superstatic 440 

Sontex's Superstatic 440 is a flow meter which is suitable for measuring flows from qp1 up to 1500m³/h and sizes from DN 15 to DN500.

Used with the Supercal 531 the Superstatic 440 forms a heat metering system fully compliant for renewable heat incentive applications.

Sontex Heat Meter - Superstatic 449 

The Superstatic 449 is a compact solution, combining the fluidic oscillation measuring principle and is ideal for low flows from qp 0..6 to qp 2.5m³/h.

Utilising a static flow sensor, the Superstatic 449 does not have any moving parts and thus no wear. The Superstatic 449 meets the requirements of EN1434 MID Class 2 and is suitable RHI applications.

Sontex Heat Meter - Superstatic 749 

Even more compact than the Superstatic 449, the 749 is ideal for less complex requirements where fewer functions are required from a heat meter.

The Superstatic 749 is an all in one unit comprising of flow meter, integrator and a pair of temperature sensors. Additionally the 749 is EN1434 MID Class 2 approved and is suitable for renewable heat incentive applications.
