Garage heater info

[OCCOBRA]

Our PE at the main office cinfirmed my thoughts on your sizing. It appears that you will have a 25,000 btu/hr load given the factors listed above. Beacon Morris (one of the companies owned by Mestek, my employer) builds a Horizontal Unit Heater Model HB125A which is rated @ 24,800 btu per hour @ 200 deg F entering and 180 deg F leaving. Since your boiler is 160 deg F setpoint you will recieve 23,882 btu/hr output when the water is hottest, and 16,516 btu/hr when the water is @ 120 deg F. As an average say at 140 deg F boiler water your output from the heater would be 20,187 btu/hr with a cold garage (30 deg F) When the room heats up you will get 14,161 btu/hr input when your garage is @ 60 deg F which will keep you nice and toasty. They max flow rate through the unit is 2.5 gpm with a head loss of 2.2 ft hd. This will only utilize a very small zone pump depending on the run. Your loacl Hydronic supplier should be aable to help you pick a pump. I currently do not have a used R & D unit. Apparently these disappear fast after testing.
Check your local supply house, distributor for our product or use another brand if you can find a good deal (you wont hurt my feelings).
If you have an old radiator that is laying around you could use hose to AN fitting adapters (Jegs/Summit have them) and use hose to connect AN/NPT fittings to your existing piping, then get a fan that will do at least 500-600 CFM to blow through the radiator. For a car guy that would really be cool and would/could be cheaper. Just a thought.
Hope this helps. Any other questions and PM me

Thanks so much, Dane. I somehow missed this when you posted it. That's great information, I really appreciate the time and effort it took for you to gather all this. Thanks again.

The best way to heat up the old workshop is to fire up Mr. Heater, sit in a circle of chairs and drink alot of beer. The bench racing alone will generate approximarely 25'000 to 50'000 BTU's of heat. If more heat is desired, turn the on game the TV or turn up the music..that's good for maybe another 25'000 BTU's.
If still too cold crack open a window and fire up the Bar-B and grill some stuff ( oh you might need a fan to blow the smoke out)...There is no limit to the methods of generating garage heat.

I have a queation, does BTU mean Buy Thermo Underwear?

Last but not least..move to Lake Havasu City in Arizona...it currently is getting down to 50 degrees at night and 75 during the day.

Good luck with heating the garage.

Bill..ps. I'm looking for my shorts and flpflops so I can go work in the garage.
