Being so large, it only runs for less than a minute cycling on & off as needed. I expect it will pay for itself the first month.
It can set on the floor with the included feet or be wall mounted with the included bracket. It's a bit modern looking for my taste but the blue flame and performance more than makes up for that minor flaw.
To connect it to a gas supply, you will need some brass fittings / hardware, a hose & regulator unless connected to your main supply. Every component is available on Amazon or your local hardware store. Don't forget teflon tape for the threaded pipe joints! Maintenance is quick & easy. Basically cleaning the pilot orfice of dust that may accumulate. The manual says every three months. My house apparently lacks any insulation and resembles a wind tunnel. (I bought it over the phone, without seeing it first lol. Initially I didn't care, I bought it for the land & planned on building a new house anyway. I just never imagined it could be this bad.) I'm in awe these two heaters can keep up but they do, and quite well! They are comparatively economical to operate too. Hopefully our new house will be finished before next winter. And yes, I'm transferring these heaters to the new place! If it turns out they aren't needed, I can put them in the stable to keep my horses warm. I would absolutely buy them again and highly recommend them! To clarify, the larger heater (30,000 BTU) in the living room would heat the entire house but the back is generally closed off. That's why I needed the smaller 20,000 BTU unit. FYI the thermostat in the living room is set about 2 1/4 to maintain 74 degrees. Obviously you can adjust the temperature to your liking. I prefer HOT. Shipping was fast and very well packed. UPS proof. After using them I suspect they would perform equally well in a workshop / garage where open flame wouldn't be an issue. Buy this, you will be VERY happy with it.
Update... After complete satisfaction with the first two, I just bought a third for my workshop. This time Amazon suggested a hose & regulator kit which I gladly bought with it. It's somewhat of a pain in the rump to find the right hose & fittings each time. This made it really easy. Everything was included but a tank (which I already have). I think it's actually less expensive in kit form as well. I might buy #4 for the barn to spoil my horses. 😉

Reviewed in Mexico on January 17, 2021
El calentador es automatico, enciende cuando la temperatura deciende y se apaga cuando alcanza la temperatura que eliges.
La falla es que cada vez que prende, el calentador lanza una llama intensa que sobresale como 10 centimetros fuera de la rejilla de protección. Esto solo sucede durante una fracción de segundo para después volver a la flama normal.
Intenté comunicarme con Mr Heater, pero nunca logré que me contestaran, ni por correo, ni por llamada, ni por una plataforma ineficiente que tienen para su atención a clientes.
Lo comento para que lo tengan en cuenta, si les toca uno que funciona bien, excelente. Si les toca falla, sepan que será dificil recibir atención por parte de la marca.
