95% Efficient Gas Furnace & Venting for a Sealed Foamed Attic

[7777dmith7777]

my furnace is 150% efficent !! I bypassed the meter with a ball valve..

Don't leave the cat litter box in the furnace room. The ammonia from the cat urine will eat away at the furnace heat exchanger and reduce the life of the furnace. Also don't store any chemicals even in closed containers, especially chlorine for pools.

I had a Trane furnace installed last year. They vented it outside and also piped a fresh air pipe but tyey never connected that pvc pipe to the furnace. They left it near the furnace and said the furnace would draw the fresh air from that pipe there. I had to put a pvc elbow on the furnace where this pipe should be because it got clogged,the furnace room has a cat litter box in it and that may have clogged the opening. Should we add more pvc pipes to connect this fresh air vent to the furnace ?

@ILoveLucyE68NY YES, for sure. This video was made during the install and the piping wasn't done. With a fully sealed and foamed attic you MUST provide piped in fresh air and exhaust for the sealed combustion. The clients got their first month's energy bill in June and it was $37 in electricity for a HOT month!

@ILoveLucyE68NY - If there are parts missing, the job is incomplete, and you are asking questions on youtube about your illegal HVAC project, then you must of hired the uninsured, unregistered group of Stooges to install that system for you. When your family gets sick because you are too cheap to have it installed properly, then you will have to deal with the consequences of endangering the lives of the people that live, and visit your home. Tell us who installed it for you, and where you live?

@mack70214 Good question. I don't believe it would burn hotter. The unit we're showcasing in this video is natural gas powered and is very efficient as it turns 95% of the gas into usable heat and 5% is lost to inefficiencies. Typical Gas furnaces are 75-80% efficient. I've never installed an oil fired unit but I would guess that they make some equipment that will use the oil more efficiently too. Hope that helps.

So knowledgeable, great video!

[MattRisinger]

Thanks for your kind words! I get kinda geeked out on the HVAC systems in my houses. Matt

It only make good sense to get a 95% efficient gas furnace.

[MattRisinger]

Yes indeed. This furnace is much more efficient than the standard 75-80% efficient models you see in most new homes. BUT, equally important is that it's a power venting model. The flue is PVC and stays cool. It doesn't use combustion air from the attic so we can use this furnace in a foamed & conditioned attic space. Plus, no worries about combustion gas spillage into your house (meaning no carbon dioxide worries). I recommend these to all my clients.
