Yes, running a jumper wire between the R terminal and the W terminal will put the heater to an always on status, heater would then be controlled by an on/off switch.

answer 4
Because this heater has a direct spark ignition, the level of energy may be sufficient to disturb the logic circuit in a microprocessor controlled thermostat. It is
recommended that an isolation relay be used when connecting the heaters to a microprocessor controlled thermostat.

I have 2 - 120 gallon tanks per 75k BTU Mr Heater. As it happens, the tanks were in place from the previous owner, so I kept them and use them sparingly. Having said that, you could get along fine with 1- 120 gallon fuel tank.

answer 2
I am not the resident product expert, but how long your fuel would last depends upon how cold of a climate you live in, how warm you set your thermostat, if you heat your building full time or only when you are working out there... quite a few variables. The reason for the need for the 100# tank is so you have the capacity to vaporize enough LP for the heater to operate correctly, especially in very cold weather.

Hi Mike.

Guess it depends on the temperature you set it at, the heat loss of your building and the environment. I typically burn 250 Gal per year keeping a 30 X 40 garage with 10" concrete walls (partially buried on rear and sides) and 10' ceilings at about 50F. NH winters are Zone 4, I would estimate in my area.

Question

I have a shop 32' X 36' w/ 6" walls 12' ceiling, Zone 4 climate. can I get by with a 45,000 BTU Htr to maintain 50 deg. and 70 Deg. once in a while?

Would it be more efficient to have a 45,000 BTU or a 75,000 BTU?
I have insulated walls , sheet rocked.
I'm not in a hurry to heat the space to 70 Deg.
The main concern is; can the 45,000 BTU maintain, or is it more cost effective using the 75,000 BTU running a shorter time to maintain a temp?

With the area being almost 14,000 cubic feet and 70 degrees being the desired temperature at times, you should be considering the 75,000 BTU heater. The larger heater is not going to work as hard, making it more cost effective and ensuring a longer life to the heater.

Yes, 45,000 BTU will woork just fine.
I have the 75,000 and my garage is 24 X 28 with 16, ceiling. I also install a ceiling fan on the other end of the garage and this works very well.I know now I could of install a 45,000 BTU and be just find. I thought at the time bigger is better . I don`t need all the extra heat it can produce.

answer 4
I'm running the 75K unit in my 30 X 40 shop with 10' ceilings, but my walls are 10" concrete. I generally prefer to go with the larger unit figuring it will more easily handle the load. That way if you have a prolonged cold snap your heater isn't running 24/7. Go with the bigger one. (My opinion only) Mine is usually set at 50F unless I am working on the tractor or washing a vehicle. Then I bump it up to 70. It takes very little time to heat things up.
