Hearth DVAG11L Liquid Propane Direct-Vent Wall Heater

Love this little wall mount heater, kept the main furnace from over compensating to heat the addition. I highly recommend.

This Ashley Hearth unit has proven to be an excellent replacement for a 20 year old unit that performed well. The Ashley draws all its combustion air from outside via the concentric through-the-wall vent pipe that also routes its exhaust. No fumes enter the room. The unit is extremely quiet and easy to light and control. The Ashley Hearth unit has no electrical connection or requirement. In a power failure, it continues to heat my small (240 sq ft) guest cottage dependably and well. I believe it is also available with a propane orfice for real off-the-grid applications.

I bought this to heat an insulated single car garage. It replaces a ventless gas heater of about the same BTU output.Installation was pretty straightforward and the directions were pretty clear. BUT I wanted to install directly to dry wall. This requires installing a six inch deep, ugly, unpainted spacer. So while the heater itself is pretty unattractive but at least relatively compact, once you add the spacer, its downright ugly and bulky.This uses a piezo ignitor to light the pilot light just like my older ventless heater but the design is so bad, it will not light. It took DAYS of fiddling to get it to light. Absolutely useless and frustrating. The ventless heater always lit on the first try. Once I finally got it lit, I thought I would just leave it on but just the pilot puts out a fair bit of heat. So I had to turn it off. I was hoping the next time would be easier but it was not.You might still be thinking that this is cheap enough that it might be worth it. I would reconsider. The thermostat kind of sucks too. Now that its been on for a few months, I can say that it can't regulate the temperature worth a darn. The ventless heater used to do pretty well. This unit seems to vary significantly. I'd say 66 to 72 is about as good as it gets. There's lots of variables so its hard to be precise. I am now trying to add a fan to circulate air in the garage but it doesn't seem to help much.Finally, I would say this is about as inefficient as it gets. Most of my heat seems to be going outside. The unit seems to be running all the time now that its December. I am not sure what my gas bills will be but I think I am in for an unpleasant surprise.

We replaced the ventless gas heater with this vented gas heater. The room is an enclosed patio pad. The 3 outside walls are full panes of glass.The heater is GREAT! We live in Erie, PA & we have COLD winters with a lot of snowToday is 28° & we are warm. The heater was professionally installed. The installer did extend the outside vent. We are VERY pleased.We'll have the wall repaired in Spring.

I have to write this review to express how happy I am with the heater. I had it installed to replace Williams 14k direct vent, the model that I had issues with since 2007 but kept buying for lack of the alternative, 3 units total in 14 years. And finally, I found the great replacement, and half the price at the same time! This wonderful heater is similar size, making constant 57F temperature, while set at 1st heat mark. I have a free standing brick studio building, with zero insulation in the walls, while outside temperature varied from 15F to 55F, the inside stayed perfect for storage. When I set the dial to 2, the temperature easily went to 61, perfect for working on projects inside, during winter in February in New York area. Didn't try 3 or 4 setting on a thermostat, no need to sweat! And the best of all, after 5 weeks of the heater operation, nor once the pilot light went out, dispite some strong winds, which caused other model I've had for years to be constantly relit (what a pain in the neck), I could never be certain the pipes wouldn't freeze one windy night! The installation went very smoothly, the hole in the wall I had before worked perfectly. My only complaint was about 2.5" screws included to mount the frame to the wall. Those stripped while being screwed into predrilled 2x4 wood frame boards in the wall. All 4 stripped completely, had to use pliers to take out, painfully slow process! Overall, I give this heater 5 stars so far.

It works quite well but it is a little small, I might have gotten a little bit bigger one but it will work. Overall very happy with it. Up date, I at first thought that it might be to small but I'm very happy to say that it's perfect for me.

Thank you!

installed unit and knob to ignite pilot would not engage. Called manufacturer who set up a claim but then failed to email me back after numerous messages sent. Finally called manufacturer again who advised me the part necessary for repair was unavailable and I should try to find one from 3rd party. Not surprisingly - there are none in the off-market place. Called and paid an independent repair company $75 thinking they might be able to jump start the heater only to learn the gas valve was also defective.I now have a non-functional 11000 BTU gas wall heater that doesn't work with no parts to repair.
