I want to keep a 2 x 4 x 2 space at 85 degrees for two hours at a time. will this heat source do it?

Henry - it might, but it will depend on the rate of heat loss - so how cold the surrounding air is, whether there is any insulation, whether the top is open for heat to rise out of your desired warm area. Mine are in an insulated wooden box that is ~3x3x3" out doors where the temperature gets down to freezing but no lower, and indoors in a terrarium that is ~1.5x1.5x4 . The temperature inside is 50-75 and the only way I can keep the terrarium cool enough (below 83) is to avoid covering the top. Best of luck.

Not sure, but I think yes. It works really well but I use it for my hedgehog and haven't gone above 80-82.

I have a 40 gallon breader tank and it keeps it around 80 threw the mesh top with about room temp at 67-70...if I place it inside the rank it will keep it around 85ish...

There is no set wattage for size of enclosure because of variances in ambient temperatures, heat retention of materials, etc. This may actually over hear that space depending. I usually get one that i know to be stronger than I need and then put it on a rheostat.

No. But even if it did, you have no way of knowing if the bulb burns out or stops working because there is no light that goes with it. It looks the same working or not. I didn't like it for that reason. But more importantly, it is not strong enough to radiate heat in a 2x4x2 space.

This dependes on whether it is an enclosed space and the ambient temperature around the space. If you have an enclosed area with household temp. around of about 65 F I would think this would work just fine. But there is not a thermostatic control to prevent it from going over that temperature.

That would be a great idea. I never tried that but don't think it would work. the controls (mine has two) have to be set manually each time to the heat setting you want. They shut off after about 10 -12 hours. They will not come on automatically by adding power. 9

No. Was told by company you need at least 2 feet of clearance from heat source.

Hello-- Yes, I've used it up to nearly 2 hours, but it gets very hot, so be careful.

Save your money. I used this for about 18 hours a day to remove heat and it lasted 1 month.. Buy this instead VenTech IF4 4" Inline Duct Fan 190 CFM and you will be happy. I have been running this between 12 and 20 hours a day for about 6 months now a great investment! VenTech IF4 4" Inline Duct Fan 190 CFM

I have not needed to heat anything yet (I live in FL) but a 14 x 14 space should easily be heated by this unit.

This may be fairly normal. Is it making plenty of heat? I know it should be able to heat a tent very nicely in an hour.

Assuming that is 25' x 25' x 10', I believe 1 unit would be challenged if you're in Northern Alberta - checking some weather info for Fort McMurray (a guess), I see 'average' lows of -10 F and minimum lows of -30 F over the last 20 years (and -58 F for the long-term). I set mine at 45 F for a 24' x 30' x10' (12' roof peak) metal building (not that well insulated) in Texas and with +8 F ambients, it was on 45 minutes/off 15. I did buy 2 but only put 1 in service, as that was acceptable to me. Also, there are recommended minimum clearances of 34" top and 68" below for these units; a 10' ceiling and a 12" unit height means you're almost at minimums (34" + 12" + 68" = 114" = 9'-6") to start. With the radiant heat flux off these units, the area directly below (or directly facing if you mount the unit at an angle, as I did) will get hot, so depending on what you're using the space for, there may be issues with localized 'hot spots'. Having a method to keep the air in the building/room well-distributed is also important (I used 2 ceiling fans) for several reason. The unit will consume O2 out of the air - about 1 cubic foot of O2 per minute. There is a recommended fresh air flow in of 160 CFM for this heater (high, IMO as a Chemical Engineer, but I'd want at least 50 CFM), so proper ventilation is also a concern if your room/building is 'tight'. You can better evaluate your specific application, but I believe one 40,000 BTU/Hr unit would be marginal in that size building (unless very well insulated) in the climate I think you're looking at.

As long as you use very hot water at the start- it will stay warm for 2 hours..

I have not done it but I believe it will. I use it in a sous vide setup, and it coasts holding it at 165 degrees F.

Yes but I'd use a heat defuser. I place it on the defuser and then start the heat medium.

So, only use it for half an hour at a time, let it cool down, then continue with the project. Mine didn't over heat.

We used it to heat approx 400 sf of garage space. I don't think it will get to the high temp you are looking for.

I used Mr. Heater in an area approx. 400 square feet. After about 40 minutes I had to turn it way down. I would say this would heat an area at least twice that size, to a comfortable temp.

"hot enough" may not help you. More specifically, two temp settings are approximately 480F/250C and 660F/350C.

I think you would need some sort of venting to occur in order to prevent expansion from the heat. It works very well the way it is designed.

For a space of 60 sq ft....I doubt it'll have an immediate warmth impact....You may feel warmth after a few hours of use...If your looking for a high output portable heater...Allow me to suggest "The Big Heater Buddy" ...It'll put out btween 4000-9000 Btu's... Check Cabelas website...The deal with refurbished units....Good Luck.
