HELP: Garage Heater Recommendation
Hello all,
I'm hoping some knowledgable heating experts might be able to help me out here. We're in the process of building a new house, and have an attached garage. The garage size is 26x24, and has a ceiling height of 11'6". The way the garage is positioned within the house, two of the walls are shared internal walls, and two are external (cold) walls. The external walls are 2x6 construction, are are R19 insulated. Above the garage is a bonus room which is finished, and has R33 insulation above the garage ceiling. And the garage door itself is very well insulated. Basically, I'm looking for a recommendation on a good heater for this garage space, since I will be setting up a small workbench area, and would prefer to work in the warmth rather than the fridgid cold My plumber originally suggested a thermostatically controlled space heater from Rinnai - the 606TRAII. Here's the link: http://www.rinnaina.com/products/hea...E606ATRAII.asp However, after speaking to the sales people where they sell this heater locally, they talked him out of this model saying it wouldn't be sufficient for this space. Now his recommendation is to setup a small furnace unit, and run duct work overhead blowing heat down into the garage. While I'm sure this second method will work just great, it's way overkill for what I'm looking to do with this garage. My original thought was to go with a simple brick heater, but my contractor talked me out of this saying it would burn up way more gas than I wanted, since it is NOT thermostatically controlled. So now I'm back to square one. My budget on this is preferrably around $600 or under. If anyone can make a suggestion that would fall into this category, I would greatly appreciate it! Kevin G. |

What does the heat loss calculation say you need in BTU? |

What does the heat loss calculation say you need in BTU? 25K BTU - http://www.northerntool.com/webapp/w...5606&R=2560 6 30K BTU - http://www.northerntool.com/webapp/w...83&R=10 29783 40K BTU - http://www.northerntool.com/webapp/w...0858&R=2085 8 45K BTU - http://www.northerntool.com/webapp/w...&R= 200307937 Well, you get the idea. |

Honestly, I don't have an answer to your question... that's getting a little more technical than I'm equipped to handle I'm guessing there is a formula to be used when calculating heat loss? The problem is, I don't know if I would adequately be able to plug variables into a formula because there are a few windows in the garage, an interior door, etc.. This would probably be something I would have to pass along to my contractor. Any suggestions on figuring this out? Kevin |

This would probably be something I would have to pass along to my contractor. Any suggestions on figuring this out? It is relatively trivial to run a quick "Manual J" calculation for your purpose. Here's an online calculator that will probably get you close enough. You can also Google on "Manual J" for more technical details and other calculators. http://www.mrhvac.com/index.html?htt...nualjshort.htm |

So if you want the inside temperature to be 70 and the outdoor temp is zero, you would need 46K BTU. Run the numbers for yourself and see what you get. |
