Hybrid Renewable Energy Systems

These are different to hybrid solar heat pumps. They are conventional heat pumps, but with a secondary heat source alongside, usually a gas or oil boiler. The idea is that you can switch to using the boiler instead whenever the heat pump is unable to provide all the heating requirement, or to operate at a reasonable efficiency.

Some people describe these as bivalent systems, but that name can be used for any heating system that uses two different fuel sources.

We can’t currently advise whether there are any situations where it would be better to fit a hybrid heat pump rather than a heat pump on its own or a gas or oil boiler on its own.
