I have a water heater in the basement that vents exhaust gases up a chimney. The chimney is only used for this purpose. My Furnace side vents to the outside of the house through a side wall using PVC pipe. Is it possible to side vent the Water Heater also, as I wish to remove the chimney from the attic for conversion of the attic? We do not have fire places etc so the chimney is pretty useless.
My understanding is that only some of the water heaters can be side vented. You may be able to do the side venting if you use a power venting system which inserts a blower to exhaust the gases, but I'd check first with your HVAC pro before doing so.
I think integradad is right. I have a Power Vent HWH in my house. It's ducted w/PVC right through the ribbon board. Once outside, by BOCA Code, it was 'terminated' 18" above ground for snow buildup reasons.
Do check w/a Pro first. My best to ya and hope this helps.
