Furnace Failure...UGH!
Ray,
Thanks for the lead. I like what I've read about Reznor so far. How long have you had your Reznor unit in use? Have you had any problems/repairs in that time? Thanks, Gene "Ray" wrote in message ... OK. Contrarian is not an unusual stance for me , so... I avoided the Southern Burners as my greenhouse would have needed several, amounting to a severe loss of plant-growing space. (If they only made a higher-output unit.) I was a long-time Modine user until the "specially for the greenhouse" unit turned out - as yours did - to be not worth a damn in the humid environment of the greenhouse. At that point I decided to go with the separated combustion type, but Modine's smallest was overkill for my GH size. I found that Reznor made one that suited the bill perfectly - it has the high efficiency heat exchanger design of the Hot Dawg from Modine, plus the separated combustion. Combined, my propane usage was cut by 40%. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Artwork, Books and Lots of Free Info! "K Barrett" wrote in message ... For what its worth I'm with Al. I have a Southern Burner heater, vented to the outside. Like an idiot, I decided to turn it off over summer (why pay for the pilot light when its summer time, I thought.) Big mistake. The humidity in the GH froze, rusted or whatever name you want to call it the valves shut. dead dead dead. I was ****ed. Luckily, I had a Grainger's catalog and for about a hundred dollars I bought a replacement valve assembly and was back in business. I have not shut off the heater ever since. The heat from the pilot light keeps enough heat at the valves to keep them from rusting over the summer. While this isn't the same as your squirrel cage assembly, it does lend credence to Al's comment that you can fix this yourself or get someone else to fix it for you for much less than you'd think.

I feel for you... look up the part number of the squirrel fan at http://www.grainger.com/Grainger/wwg/start.shtml, if it is what you need and a good price buy it and find somebody ELSE to install it for you. Those heaters that draw the combustion air from outside the greenhouse are better for a variety of reasons. My heaters have both been on very good behavior this year. Only one nozzle replacement needed on one of the two. On the subject of rust... When they came on last fall they spewed out a fine coating of iron red rusty dust on all the plants below. I can not imagine them lasting 20 years. "Gene Schurg" wrote in message news:MwV%f.6575$MU4.6227@trnddc03... If I had hair I would have pulled it out by now. A week ago my 4 winters old Modine HotDawg natural gas heater stopped working. It would not fire. Luckily it's been warm enough to keep the greenhouse warm with house heat so I am not too concerned. If this had happened in January I would have been frantic. After numerous phone calls to the manufacture and their rep I was told that any HVAC company should be able to work on it. I called a local company who took their good old time coming out and the repairman took two hours to figure out what was wrong ($255.00). The squirrel cage that exhausts the heater has rusted and fell apart. The HVAC company took the part and today 4 days later called to tell me the part was going to cost $650.00. I was shocked since the whole heater only costs $550 online at numerous sites. Once again I called the manufacturer's rep who told me the part lists for $141.00. The HVAC company says too bad that their price is $650....plus installation. Now I'm thinking about cutting my losses and just getting a new heater. I need 45,000 BTUs and it has to hang from the ceiling. The Modine Rep said the greenhouse environment is why the furnace failed after 4 years. He says the new ones that vent air from outside are better because they don't have the humid air of the greenhouse rotting the insides. The ones vented from the outside are double the price of the model I have now. I thought I'd ask the experts in here what their experience is with gas furnaces. How is your greenhouse furnaces holding up? Would you recommend it? I'm hesitant about making another investment in a Modine product. Good growing, Gene |
