If your boiler is older, repair costs are climbing toward the price of a new unit, or it needs frequent repairs each winter, replacement usually makes more financial sense.
Can a new boiler use my existing radiators?
In most cases, yes — we evaluate your existing piping and radiators as part of the assessment and let you know if anything needs updating.
