At Worcester Bosch, we pride ourselves on pioneering new technologies to lead the way to the next generation of home heating. Here you can read our findings from our recent trial at the University of Salford on our CS5800i Hybrid Heat Pump system and learn how hybrids can help the UK contribute to the government’s Net Zero targets.

“We strongly believe that hybrid systems are viable - and essential - alternatives for home heating. And importantly, will directly contribute to the government’s 2050 net zero target. This first-of-its-kind trial is proof of this.”

Carl Arntzen - CEO

What is a hybrid heat pump system?

A hybrid heat pump system typically combines two proven technologies: an air source heat pump and a gas or oil-fired boiler, managed by a smart control unit which acts as the ‘brain’ of the system. The control unit will choose to use energy from the heat pump and the boiler depending on factors like the outside temperature and the cost of electricity at the time.
