Make sure your heat pump stands out from the crowd

The Passiv Smart Thermostat is the perfect partner for a heat pump

The Energy Saving Trust has verified that the Passiv Smart Thermostat increases the efficiency of a heat pump by 17%. It can also optimise a heat pump to consume cheap electricity from smart energy tariffs and rooftop solar generation. Taken together this can reduce your customer’s heating bills by up to 30%!

The Passiv Smart Thermostat learns how a home heats up and cools down. It uses local weather forecasts to start heating a home and hot water at exactly the right time to make keeping comfortable with a heat pump simple for your customers.

The Passiv Smart Thermostat removes the need to set a weather compensation curve. Instead, it learns how a home heats up and cools down and continuously optimises the heat pump’s flow temperature to maximise its COP.

The Passiv Smart Thermostat can be installed with wired or wireless thermostats. The Passiv Programmer features a built-in, push-fit wiring centre and is also used to commission the system in under two minutes without a smartphone or internet connection.

Reduce heating bills by up to 30%

The Passiv Smart Thermostat learns how a home heats up and cools down and uses local weather forecasts and smart preheating to deliver perfect comfort for your customers.

At the same time, it continuously optimises a heat pump’s flow temperature to maximise its efficiency while also accounting for smart energy tariffs and rooftop solar generation. Taken together this can reduce your customers' heating bills by up to 30%!
