Need to buy a new gas boiler.... help!

JCR Member Posts: 1
I need to buy a new boiler and water tank. I have underfloor radiant heating system (copper pipe, 1950's). I have no idea where to start. I have 2 kids so we use a fair amount of water. Someone recommended the Boderus GC124. Not sure if a combi may be the better option?

    Find a competent contractor who can perform a compete heat loss of your home. He should also be able to calculate the First Hour Rating and hot water recovery needs for your family. Without those 2 critical calculations, we would all be guessing at which system is right for you.
