Hot water heater: indirect or regular?
We're planning on replacing our cracked oil-fired steam boiler (Burnham) with a gas-fired unit (Weil-Mclain). Currently, our hot water system is a SuperStor GL-50 storage tank with a tankless coil inside the Burnham. This tank is about 5 years old and so far is working fine. Our plumber suggested that we replace the tank with an A.O. Smith ProMax 50 gallon gas water heater, instead of keeping the SuperStor and replacing the coil, because it would be more efficient. However, my research shows that indirect water heaters are considered more efficient.
Which would be better for us? Naturally, we're looking for the most efficient water heating that we can afford - less than $1000 for the tank - and our boiler is in the basement and connected to the chimney flue. We live in NYC.
Appreciate any advice you can give me.
