John Bacon Posted December 11, 2006 Report Share Posted December 11, 2006 is there any other benefits to going to a high efficiency I am missing? Gerritt. If you have a high efficiency furnace you don't need to use a chimney. They are vented through the wall via a plastic pipe. If you do not have any other appliances that require a chimney, then you may be able to remove the chimney and use that space in your house.

danc Posted December 11, 2006 Report Share Posted December 11, 2006 I think your logic is backwards. There is more benefit to having an high efficiency furnace in an inefficient house than there is in an efficient house. You are absolutely right John. But I think that in Gerritts case, a mid makes more sense simply because he stated what his heating bills are now and what his savings will be. But you are correct in the fact that an older, less efficient house would benefit the most from a high efficiency furnace. Link to comment Share on other sites More sharing options...
Daplumma Posted December 11, 2006 Report Share Posted December 11, 2006 Especially if you duct in the combustoin air from the outside(90+).The furnace wont pull the combution air thru all of the nooks and crannies of the house.Went with the 90+ in the old and new section of the house and it saved me quite a bit.The wood stove helps in the romm it is in but I'm sure its a break even thing for the overall house efficiency.

Daplumma Posted December 12, 2006 Report Share Posted December 12, 2006 Looks like a good solid unit with a pretty good warranty.Enjoy the new heater.Make sure the tech checks the wiring and T-stat and sets the heat anticipator for that unit.

Gerritt Posted December 12, 2006 Author Report Share Posted December 12, 2006 Hey Joe... it comes off the same line as the carrier unit.. the t-stat wire is being replaced and a new programmable t-stat installed... I think I did ok in terms of priceing... 1750.00 CDN for the furnace, installation, new t-stat and chimney liner.... hell cheapest place I found for the liner installed was 400.00.. I think I am getting a good deal considering my in-laws just paid 3000.00 3 months ago for a mid (non brand name) and did not require a liner... Gerritt.

Daplumma Posted December 12, 2006 Report Share Posted December 12, 2006 Good deal bud.I'm not too familiar with the pricing on units anymore.The last two I installed were for my house so the labor was free..sort of... Joe Link to comment Share on other sites More sharing options...
Fisherman Posted December 13, 2006 Report Share Posted December 13, 2006 Daplumma: Question, if I'm going to install a new gas furnace, do I have to replace the B vent chimney that's in there now? It's been in there for 20+ years. Thanks. Link to comment Share on other sites More sharing options...

It's been in there for 20+ years. Thanks. Unless your b vent galvanized exterior is rusted, which is possible above the roof line, then it's fine. I've never seen the aluminum lining wear out. If it's rusted above the roof line, then you only need to replace the top section. Link to comment Share on other sites More sharing options...
Daplumma Posted December 13, 2006 Report Share Posted December 13, 2006 Take a look up in the pipe and like R2 said if it looks good it should be OK.Make sure the new funce in not a condensing furnace though. Joe Link to comment Share on other sites More sharing options...

I've never seen the aluminum lining wear out. If it's rusted above the roof line, then you only need to replace the top section. When I installed my gas dryer I was told that I could not use aluminum vent pipes because they would react with the exhaust. Would this not also happen with a furnace and aluminum liners? Or, was I misled? Link to comment Share on other sites More sharing options...
steve_paul Posted December 13, 2006 Report Share Posted December 13, 2006 We vent dryers with aluminum John, don't think you should have a problem. Fisherman, if you have an existing B Vent chimney you can use it for your new furnace, it just has to be sized properly. If you are going with a mid and have a conventional vent water heater, likely should be a 5" chimney, if you go to a high and still have a conventional vent water heater you would need a 4" chimney. Whatever the configuration is, the contractor will put the right size aluminum liner down the existing B Vent to code. Gerritt, good luck with the install and don't forget to send in the rebate form for the programmable stat - you will get $75 dollars back from the OPA and $15 from Union Gas - $90 for fishing stuff!!!!!! Sounds like your parents either got some added features with their furnace (2 stage heat, variable speed motor) or some contractor did very well for himself.

Fisherman Posted December 13, 2006 Report Share Posted December 13, 2006 Okay, did the exterior inspection, no rust, still looks fine. It appears to be a 6" exterior, 5" interior. After seeing Gerritts 4 tube heat exchanger, I'm beginning to wonder, mines only a 2. Mybe time to start looking for something a bit more efficient. 65000Btu input, 49oooBtu output.
