My son/ wife live in Connecticuut, in an area where natural gas is not available. He has (had) a oil fired boiler, that provided both heat AND hot water.
Most recently he has added a pellet stove insert, that WILL provide (most of) their home heat. He is now considering a tankless water heater, thus stop using that boiler for (only) their hot water.
Would an electric, tankless Water heater be a viable option ?? (The oil boiler would then be a Back Up home heating option, but not used daily/ year round).
He has spoken with a contractor. The contractor recommended a new, "Expensive Propane Hot water install. That does not seem viable to me, given that they use a limited amount of hot water daily.
