Boiler air Intake

Boiler air Intake

Boiler air Intake

I am proposing a 3 modular HW boiler system for space heating purpose with natural draft. The installation is in building basement. For air intake system field guys usually complain for cold air from outside.
I am thinking of pre-heating intkae air. I wanna know is it right approach or is there any other way of doin it? If yes what should I use for it. Total boiler hp is 146.
Appreciated for support any related references.

RE: Boiler air Intake

One method to avoid cold air would be a to use sealed combustion boilers, where the inlet is ducted directly into the combustion chamber.

Many/most boiler manufacturer's offer this as an option.

I'd also consider cross-posting this over to the HVAC forum:


RE: Boiler air Intake

I have to agree with Chris on this one. We have used sealed combustion boilers and are great.

RE: Boiler air Intake

Another vote for Chris - Sealed combustion/direct vent is the way to go.
