Ok after 16 years my 30 gallon super cell finally is leaking time for something new. So what's my best option here? I can replace it with another cell similarly and do it myself or should I have a plumber put in a coil? The boiler is a Peerless 4 section with the usual side by side setup in the basement.
Is there really any benefit to having one versus the other efficiency wise or is that all talk?
