Passiv UK

The Passiv Smart Thermostat is the first smart thermostat designed specifically for controlling heat pumps and is the result of over 10 years of R&D in low-carbon heating. By making heat pumps simple and affordable, the Passiv Smart Thermostat can play a big role in accelerating heat pump adoption, helping to achieve the government’s ambitious target of 600,000 heat pump installations per year by 2028. The Passiv Smart Thermostat can reduce a heating bill by 30% - the Energy Saving Trust verified that it increases a COP by 17% and it can optimise to time-of-use tariffs and solar PV too. By learning how a home heats up and cools down and optimising a heat pump to local weather forecasts, it makes keeping comfortable simple (while also removing the need for an installer to set a weather compensation curve). In 2023, Passiv launched Greener Grid Payments – the UK’s first automated Demand Side Response Service for home heating that pays homeowners up to £100 a year for using their heat pump, with no impact on home comfort! The Passiv Smart Thermostat is made up of the Passiv app, Thermostat, Programmer, and Hub, which together provide simple, smart control of heating and hot water using either the in-home devices or remotely on a smartphone.
