Qmark SSHO4004 Smart Series Digital Programmable LED Touchscreen Wall Heater for Home or Commercial Use, 4000 Watt, 240 Volt, White

I have a 3 season room that I wanted to turn into a 4 season room and this heater did the trick. I looked at installing a baseboard heating unit but it required that I tear up my kick moldings, required a remote thermostat, and would not force the heat into the room. When I sized the heater to the room (easy calculation - floor area x 10 = watts you need) I wanted a heater which pushed the heat into room.The installation was a snap in spite of the installation manual. The bottom line: cut out a 18 1/2" high opening in the drywall between 2 studs (assuming they are 16" on center) and the hard work is mostly done. The wiring threw me for a loop - I am used to using 4 conductor wiring for a 240V application. In this application you use #10-2 conductor wire - which actually has 3 wires in it. The middle ground wire serves the same purpose as the white (neutral) usually does. Make sure to use #10 wire - the unit draws 16.5 amps at full load. #10 will handle 30 amps so you have a generous safety factor. I used a double throw 20 amp breaker. The unit has a thermal safety feature so no fears there.Overall I am very pleased with this unit. It is reasonably quiet, very compact, and heats my 13' x 18' room quite well. It took a few days to get the room temp back up to 68 degrees but that was more of an issue with my floor (ceramic tile on cement) than the heater. This is a great heater for any cold room you may have.

After installing the heater the unit smoked and did not work. I am waiting for a reply from Marley. Will update after hearing back.

I researched wall heaters extensively for about two weeks, and settled on this one, based on the btu's and the fact that it is programmable. I just got it fired up: Easy to install, easy to program, and heats our large bedroom very well (about 500 square feet.) I love the fact that you can program it so that it's only on when you need it to be; shuts off when it reaches your desired temp; and there's a vacation "hold" mode too. Zone heating is working well for us, since heating oil has gotten so expensive. We don't use our oil furnace now much at all; we installed a wood stove for the main living area (about 1500 square feet) and now this Smart Series Heater. -So far so good, and both have already paid for themselves in fuel cost savings.

Great heater. Works great and I have seen a decrease in my electric bill since I had these heater installed. (average bill $220 down to $170) during the weather months. Keeps a large 20 by 18 room(old house) very comfortable.

Heater only lasted 3 months (December 2022-March 2023) before quitting and not able to turn back on. Control screen not showing anything. Still waiting for electrician to come and pull unit to determine why it completely shut off and won’t restart. Very disappointed!

Me agrada que calienta muy bien y papito.

Works pretty old keeping the room warm but is very loud. It's a constant loud noise when it runs. Which is almost all day to keep up with the cold we've been having.

I looked at many different models and ultimately picked this heater because of its rating. I am happy with my purchase. I rated this a 4 for only one reason, the shipping. I received the box with the unit that has now protective foam around the heater, packed in a bigger box stuffed with a little packaging paper for padding. Of the two I received, one had a bit of damage to the box and the fan frame was bent slightly. Fortunately this is all thin sheet metal so it was easy to just bend back. Everything works fine and they keep the house very comfortable.

Pour du chauffage. excellent produit, mais compliqué à programmer
