Question: does it have a thermostat?
Document: Then you have to hold that pilot for a solid minute or longer to keep it from going out. Once going the heat takes quite a while to warm a space up. I honestly wish I would have bought something else. When temps dropped into the 30's outside it took 1.5 hours to warm up my well insulated space. Kind of disappointing since I use it as a home gym area and need it to warm up much faster than that.
The main furnace went out the other night and we didn't even realize it until lunch.Just this week the oxygen depletion sensor started shutting it down. I reread the manual and realized I had never cleaned it which requires only a Phillips head screwdriver to take it apart, Windex to clean the surfaces, and a straw to blow the dust out of the burner. When the flames stay yellow on the tips it is time for a cleaning.
The Pro-Com wall heater I purchased for my 192 sq ft garage/workshop. The shipping I was a little disappointed with since it took almost a full week just to leave the shipper but it was free so I anticipated a wait regardless. The unit itself was a bear to get working well. I ended up needing a 2 stage propane regulator which is not spelled out at all in the ProCom manual.
Our finished basement is so cozy with the gas heat! I was worried about how to use it at first, but we really need it in our finished basement during the winter. It's great.Update: It quit working after just a few months. It worked great, but the handle that you turn seems really rinky-dink and we can't get it to work now. It got harder and harder to light the pilot light until it stopped lighting at all.
If you need something to run for many hours it is just fine then.
I thing that this is due to timing. If too much gas enters before ignition, the oxygen safety sensor kicks in. Usually, letting it rest a while will result in a start. The start button sticks from time too time. Good quality components inside and easy to switch to propane in an emergency.
I bought this for backup heat as our central furnace is very old and the pilot goes out occasionally. We also live in an area where power has been out for ten days twice in the past five years. Once I installed it, I decided to leave it on to save on heating bills. Now our 60% efficient furnace kicks on half as often saving us enough to pay for the heater.
I LOVE this little heater! It works very well and it's tiny. Doesn't take up a lot of space in the little area
However, the company I purchased it from was kind enough to refund us. I am interested in getting a similar product, but perhaps a different brand.
Different dealers on Amazon where out of stock on this heater. Amazon referred one more and they were actually cheaper.I am heating double the capacity. Good thing that is not so cold in California. Next winter I will buy the larger unit and we will use this unit in the smaller room. Got rid of the ceiling mildew problem due to an old fashion central floor heater in this uninsulated,turn of the last century,farm house.
