Comments: After almost 20 years, my existing wall heater finally pulled it's last breath, and passed on. As the heater is located in our garage/paint studio, and, as winter was fast approaching, I hit the web to find a replacement. As I am in no way an electrician, I looked for, and found, a unit that matched the old one, that had good on-line reviews. A further search led me to Heater Home where I found a competitive price, and made my order. Within a week, the heater was received,self installed and was functioning great. While I have only had the unit for two weeks, it's doing everything I want it to do, and I could not be happier.

Review Title: Good value, but loud
Comments: Overall it works well. But it is relatively loud. Obviously there will be "air" noise from the fan, but beyond that there is a loud hum. I replaced an older fan and it had essentially no hum, just the air noise, so this one is much louder.

Comments: The heater was easy to install I already had an existing 240 outlet so cutting the hole was the biggest job, the auto thermostat is nice which allows me to leave the shop without concern, thanks also for your quick delivery.

Comments: Needed more heating power over a 110V wall heater in a large bathroom. The Q-Mark LFK404 220V unit blew me away. Even at half power the room is nice and warm in less than 3 minutes.
