Answer: 
Technically, about 400 sq. ft. I use it to heat about half that: one 12x10 room and one 8x8 room. The unit is attached to the far wall of the larger room. It will bring both rooms up to temperature moderately quickly, depending on several factors. The smaller room always remains somewhat cooler, of course.

What prevents rain from entering the heater through the vent?

This question is from 14,000 BTU/Hr Direct-Vent Furnace Natural Gas Heater with Wall or Cabinet-Mounted Thermostat
Asked by
Read all my Q&A
December 17, 2015
I have purchased this unit and inspected it carefully, and from what I can see there is nothing to prevent rain from entering the intake or exhaust vents, flowing along the ducts, and from there falling into the heater. The ducts are completely horizontal and have nothing protecting their exposed ends from the rain. The cap on the end of the ducts is vertical, and several inches away from the ends of the ducts, and, as such, provides absolutely no protection from rain. In addition, the collar around the outside end of the exhaust vent will easily catch rain and hold it, since it has no drain hole on the bottom. This seems like a recipe for promoting rust.

I contacted the manufacturer about these issues and was told that nobody had ever mentioned them before. They had no answers to offer. This greatly concerns me.

The only solutions I can think of are 1) build a little roof above the vent, or 2) install the heater at an angle so that the vent angles slightly downward as it leaves the building, thus preventing water from flowing in. Neither of these seem like very satisfactory solutions to me. I would appreciate any advice about this potentially serious design flaw.

Answer: 
Clarification/correction of my question: further inspection of the ducts has revealed that there is a weep hole in the collar which will drain any water that enters the collar before it gets to the outer duct, but I see no such system for the inner (exhaust) duct, which is also exposed to the rain. So the remaining question is: what prevents rain from entering the inner (exhaust) duct and flowing into Read More
