No disappointment here

Expensive to run, but works well
This item works well on our generac generator. Note that it is 1500 watts. Similar to other brands. Looking at our electric monitor, it is running at about a 50% duty cycle in 50 degree weather. That means over 24 hours it is using 18 kWh of electricity. At our electric rates, if we left it on all year it would cost around $2000! We will only switch it on if we get cold weather which is rare in our location

Pretty Good Especially When Price is Down
We have several chicken houses that we inherited so from time to time we have to replace this. It’s a pretty good deal. They work well and seem to last so far.

Fit perfectly, working well
Was a perfect fit for the one that stopped working. Be sure to follow directions to purge any trapped air after you install it.

Works well
Mounted onto a Ford 3400 Diesel. Heats engine up to starting temperature within 2 hours. Longevity yet to be understood.

Good Quality
We use these on our standby power generators to keep the engines warm and ready 24-7-365. They last several years heating around the clock.
