Think about heat pumps and it might be electrically driven heat pumps that you think of first. Heat pumps can, however, be driven by heat itself rather than an electrical compressor. That’s where thermally driven heat pumps (TDHPs) come in.
And while boilers are efficient, thermally driven heat pumps are a step above, capturing the low-grade heat from the surrounding air and combining this with the efficient combustion of gaseous fuels. So, what part do thermally driven heat pumps have to play in the future of the energy transition?
