If you can operate a condensing boiler in condensing mode, the building is ready for a #heatpump! Don’t you think? Blending in hydrogen is like mixing Bordeaux grand-cru with coke!https://twitter.com/theheatinghub/status/1237082086978224131 …
Converting to heat pumps could triple the efficiency of the heating system and is much better than making a low-efficiency gas furnace just a little less inefficient. Given that heat pumps are available, no gas furnace should be considered anything but low-efficiency.
