Yup, and H2O, and pretty much nothing else. 95% efficient IIRC.
But they all are, you can't buy less efficient CH units anymore.
Even so, the end to that is coming.
More and more new houses have no gas anymore. A connection to the gas network used to be mandatory, now it comes at a premium. Heat pumps, solar collectors/boiler/preheaters and PV panels to compensate for the pump electricity usage, induction cooking and extreme heat isolation with controlled heat exchanger ventilation are the norm for new buildings.
They built a new residential area next to the municipal swimming pool we frequent, all of the hundreds of houses there are built like that. Concrete house, entirely plated with a foot of foam, then a brick layer around that. Climate neutral, supposedly, with just 8 to 10 PV panels each...!
