Do you have a furnace or water heater located within a bathroom or bedroom? The water heater location and that of a furnace is very important. If you own a home or are about to buy one, there are some things you need to know.
It may seem obvious, perhaps even logical, that having a non-direct vent gas or oil-fired furnace / boiler or water heater located in a bedroom (e.g. in a closet / room only accessible from the bedroom) is a bad idea from a fire safety perspective, not to mention dangerous by-products of combustion such as Carbon Monoxide (CO).
Water heaters are not permitted to be installed in a bathroom with a shower either, unless they are power vented and have adequate combustion air not supplied from the bathroom (or bedroom) they area contained within. A natural draft water heater can be installed in a “room” that you gain access to through a door from a bathroom or bedroom so long as that “room” has the same or larger volume as the bathroom or bedroom.
If you’re not sure about whether your water heater or furnace is located properly, or someone has built something around it or enclosed it, consult a professional.
