A microwave-powered boiler has been developed by company Heat Wayv, with the inventors of the boiler believing it could be a straightforward replacement to gas boilers, with zero carbon emissions. The microwave-powered boiler uses electricity to heat water, which is then pumped through existing taps radiators and taps in the same way that gas boilers work.

The boiler is currently in the prototyping phase. Heat Wayv are expecting to be able to trial the boiler in homes by the end of 2022, with first sales to customers in 2024. The cost for a three to four bedroom home is expected to be around £3,500 – roughly the same amount as an equivalent gas boiler.
