I would buy this again and from Supply House
I needed to replace a Qmark heater which had been discontinued. This one met the specs and slid in perfectly to the previous cut out. It works great! The price was much lower than my electrician's supply house.

The fan on this heater is cheap and noisy.
The fan on this heater is cheap and noisy. The only good place for this heater is in a garage. It took an hour to get the rattle out of it, and then when you put the cover back on something else starts rattling. When the fan is running you can hear it two rooms away, There is no way it has to run at the high rpm's that it does to blow that small amount of heat around.

Better packing needed
Product is working well but it was packed with no protection to the face of the heater. The face was scratched and one louver bent. Packing needs improvement. There was no damage to the outside of the carton so I don't think it was an issue of rough handling.

Using these heaters as a secondary heat source as needed. Easy to install in wall between 2x4s. Generates a ton of heat. I like the simplicity of the design.

Q: how much electricity does it use (what is the cost to operate), is it cost efficient?
Asked by lorraine 12 years ago

Energy is energy. Unless there is a lot of heat loss in the room, any heater that does not lose excessive heat elsewhere (up a chimney or out the back and sides of a unit like this), will be equally efficient. The issue is cost/BTU, cost/watt or whatever unit of energy/time you choose to use. Electricity is about twice the cost rate of gas in the Midwest, but it is much easier to snap in a breaker and pull some wire. This is a pretty standard unit. Well made, but not fancy. There is a little fan noise that is acceptable. Hope this is helpful.

I don't know. I use it to heat a 3 car garage in the winter for short time periods. It works fine & is quiet. I don't use it for extended periods, so it does not affect my electric bill.

Q: what size room does this unit heat?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe answer depends on the BTU requirement of the room. Depending on your climate and heat loss, the LFK404 should be able to handle somewhere around 200 square feet.

Q: What is the fan speed in RPM? Reason I ask is I'm looking for the most quiet heater in the 4kW range for a basement home theater. I'm open to other suggestions for a quiet fan-forced air heater.
Asked by edn116 15 years ago

Verified Reply- PexSupply StaffThe motor on the LFK404 runs at 1550 RPMs.
