28 January 2026 – Passiv UK and Worcester Bosch have joined forces to offer advanced smart controls for heat pumps. The Passiv Smart Thermostat now works seamlessly with the Worcester Bosch Compress 2000 Air Source Heat Pump range, making intelligent, energy-efficient heating controls more accessible to UK homeowners.
Thanks to its out-of-the-box compatibility, no additional hardware is required. Installers can fit the Passiv Smart Thermostat with both new and existing Worcester Bosch Compress 2000 heat pumps, making smart heating simple. The Passiv Smart Thermostat then removes the need for an installer to set a weather compensation curve, dynamically optimising the heat pump’s flow temperature to improve its performance.
For homeowners, the Passiv Smart Thermostat makes keeping comfortable effortless. It cuts heating bills and improves heat pump efficiency. Its intelligent controls can optimise energy use according to time-of-use tariffs and rooftop solar generation, supporting decarbonisation efforts while future-proofing homes against rising energy demands.
Ian Rose, Sales and Strategy Director at Passiv UK, said: “This collaboration is a major step in giving both installers and homeowners a simple way to control and optimise heat pumps. Whether a customer is installing a new system or upgrading an existing one, the Passiv Smart Thermostat helps enhance comfort, save on bills and reduce carbon emissions.”
Andrew Keyworth, Head of Business Development (Electrification) at Worcester Bosch, said: “Partnering with Passiv UK allows us to offer our customers a smarter, more efficient heating experience and we are very pleased to be working together.”
The Passiv Smart Thermostat is available nationwide through local plumbing merchants and select online retailers.
