Boiler / Hot Water Heater Recommendations

[Joshua D.]

Hey All -

I've got a 58 year old boiler in my house that needs to be replaced and I'm looking for recommendations. What does everyone suggest?

I'm willing to consider just going with a new boiler, or a tankless water heater . . . can anyone with knowledge share pros/cons of what's out there?

Thanks guys!

Regarding tankless, the gas line and main must be able to support these; not all lines can supply gas flow needed for tankless.

What kind of efficiency are you looking for? Starts at 80% and goes to 95*%. Then we need to know the venting that this house can support. Direct vent is common for the higher efficiency units; your existing system almost certainly is chimney vented. For direct vent, the unit will need to be located near an exterior wall.
