Replacing hot water tank for radiant heating system
Currently, the condo I'm living in has an indoor closet w/ a combination hot water heater supplying hot water and the hydronic radiant heating system. I live in Seattle, so heat is needed for much of the year. The tank is an expensive Bradford White model that costs ~$2000, but the existing tank is leaking.
One plumber suggested a simple drop-in replacement. But this would still be quite expensive due to the price of the tank.
Another plumber suggested a tankless replacement. Normally it's an expensive upgrade, but since a traditional tank is so expensive anyways, the cost would be similar. Would such a system be appropriate for my situation? Also, I've seen hybrid models (w/ a small reserve tank as a buffer) -- are these worthwhile?
