Jeff Remas Posted December 31, 2008 Report Share Posted December 31, 2008 You are inspecting a 20 year old home that is not considered to be unusually tight construction. The family has recently finished the basment and has framed around the utility area creating a separate, nice size utility/mechanical room of 12'x12' with 8' ceilings. The room has an energy rating and is sealed. All combustion air comes from within the room. In the room is an electric hot water heater and a gas fired hot water boiler for the hot water baseboard. The boiler has a 60,000 BTU input rating and a 52,000 BTU output rating. Is there enough combustion air in the room? Quote Link to comment Share on other sites More sharing options...
