Is hydronic heat worth installing in an old house?
I have a client who is convinced that replacing their 80% gas-forced-air furnace with a hydronic system will improve their comfort. The plan is to install a gas-fired boiler to serve both the heat and domestic hot water needs, and staple PEX below the floor in the joist bays. We've discussed the options of a more efficient furnace, or a duct-less mini-split, but byronic is still their preference.
There is not, unfortunately, any enthusiasm for insulating or air-sealing this old, drafty house. Can their goal - increased comfort - be achieved by changing to a hydronic system, without any improvements to the envelope, or is this a waste of money?
