This is a nice heater, smaller and lighter than one might think, which is a good thing.

I did the installation, power and control wiring myself and it was all very straightforward & relatively easy.

I had my energy provider plumb and run the propane and the heater fired right up. Beautiful heat for my 40’ x 30’ greenhouse in central NY.

We have been using Sterling heaters in our greenhouses for years. I like that we don't have to pay extra for sealed combustion any more.

Very easy to install. Finished getting the wiring done yesterday with a new thermostat. Our HVAC contractor was impressed with the unit. Fired right up after being connected to everything. This is for a volunteer fire department, had a Sterling unit there before that lasted for 30 years. Hoping this will last that long!
