Mr Heater 25000 BTU
By A Customer
This is a really nice unit if it fits your purpose. I must stress however, that is if it fits your purpose. As I now realize, 25,000 BTU/hr is not an enormous amount of heat. This unit really is designed for use in a closed in space w/ minimal air curculation. The heating method is to raise the temperature of all objects in the radiant field so that the space stays warm. A breeze or draft will reduce it's ability to maintain the heat. The unit comes with a thermostat for mounting on a wall and setting a desired heat. I've eliminated the thermostat and just hard wired the unit. If it's cold enough to have it on, then I want it on. Mr. Heater advertises using the term "millivolt" ignition or something to this manner. This is misleading. This is not a electronic ignition unit!!! This means the unit has a pilot light. The pilot light heats a thermocouple which provides the "millivolt" current they refer to. The thermostat either "opens" or "closes" the circuit, depending on the temperature and thermostat setting. The "closed" loop opens a solenoid valve in the pressure regulator which releases the gas to the burner.

My unit is installed on a large covered patio outside approximately 8' above a sitting area. Sitting below the heater in a 8' diameter circle is nice and toasty, even with a slight breeze. Sitting across the table at 12' you can feel a slight warming effect with no breeze. More than 12' away....no impact. This is not a highly effective heater if used in an open space. As advertised....this is a garage heater. To get the heat I need I am adding a second heater across the patio from the first.

Clearances around the unit are important. I have 2' clear above my unit, and the lumber above the unit gets warmer than I would like. After 2 hours of use I can touch the wood with my bare hand without having to remove it, but it is quite warm. I'm thinking about 120 to 130F. I have some harditrim up there too and i t is even warmer. Not too sure how long the paint will last.

Installation is a breeze. Includes a video if you need it, but there is essentially nothing to it.

Good buy....if it's what you need. If you are thinking of installing it outside......you may want to consider getting more BTU's.

Good space heater
By S. Lau
I have used this in my garage for several years now, if I have my garage door closed it will warm the space pretty well. Directly under the heater its really nice and toasty, but the furthest corner of the garage will still be cold. In a 20-degree day with the garage door closed (I have a two-car garage with most of the garage walls NOT insulated), I get over 70 degrees directly under the heater (where I usually change the oil etc.) and at least 40 degrees at the coldest corner of the garage. Most of the garage becomes very comfortable to work in, that I usually don't even need to wear a jacket. BUT - as soon as I open the garage door, I lose all the warm air and it takes a little while to heat the whole place back up. That being said, I typically also let it run for an hour or so before I start working on my car, just so I know the area is nicely heated.

Hope that helps. :)

Good cheap garage heater
By Palhaco
I purchased this heater about 2 years ago to keep my garage about the freezing level, principally to melt ice and snow from the cars, but also to provide a comfortable sleeping environment for my dog (and to keep his water from freezing). For this purpose, it works very well, and even keeps the snow melted from my snowthrower, which I keep on the opposite side of the garage. It was quite easy to install after getting all the proper fittings and hoses, which are not included.

I do have some complaints, which keeps me from giving this 5 stars.

1. Clearance is very important. When the burner ignites, I'm always alarmed because of the small ball of fire that the heater emits across the burner.

2. Because of the radiant heat nature, I have burned my hands while working under the heater, similar to getting a sunburn.

3. I've had problems with the pilot light going out. It is easily adjustable with a screwdriver, but is very sensit ive and this was very annoying to fine-tune in the beginning. I still have to adjust it about once a year.

4. The garage always smells like natural gas.

This heater worked well in my situation, because I had natural gas stubbed into the garage when the house was under construction. Had I not done this, I would probably opt for an electric heater next time, and this means you need 220 volts. Depending on the size and type of heater, most also require some type of vent.

I would recommend this heater as it works as advertised for my 625 SF garage. However, I also recommend you explore other options first.
