Solar heat meter
Renewable Heat Incentive (RHI) compliant solar-thermal heat meter.
Essential for non-domestic RHI claims.
Product information
- This MID class 2 RHI heat meter is fully compliant to monitor eligible heat use for RHI claims in buildings.
- Calibrated for Tyfocor L @ 40% solution, ready to use with our Trigon solar solutions and Dorchester DR-TC solar water heater.
- No moving parts make this the ideal choice for long term reliability.
- Compact, tamper protected unit gives easy to read data, clearly displayed on the unit.
- Buy in confidence from a UK manufacturer with decades of commercial heating and hot water expertise.
