We pay you!

Sign up to Greener Grid Payments - the UK's first automated Demand Side Response Service for home heating - and get paid up to £100 a year for using a heat pump.

Take the guesswork out of heat pump installations

The Passiv Smart Thermostat removes the need to set a weather compensation curve. Instead, it dynamically adjusts the flow temperature to ensure a heat pump runs with maximum efficiency.

The Passiv Programmer contains a built-in push-fit wiring centre to speed up heat pump installation. The Programmer is also used to commission the system in under two minutes without a smartphone or internet connection.
