they should last a long time. My first one is a year old and is working fine. The thermostat
on the second one stuck after 2 weeks. I had a bad experience with this company (not amazon)
with the first unit. You will notice that there is not a lot of information in the description. I wanted
a heater with a low and high setting. While it is not mentioned in the description, the picture
clearly showed 2 settings. The unit I received only had one. I emailed the company thinking
they sent the wrong heater. I was told the picture was of their 240 volt heater and the 120 volt
has only one setting. They would be happy to take the unit back if I was willing to pay $37. Since
their ad did not properly represent the product, I felt they should take care of it. Subsequently
purchased a couple of Patton milkhouse heaters with 2 settings through Amazon for $30 each.
They are performing just as well in the greenhouses. (yes, I have a number of greenhouses)
1500 Watts is 12.5 Amps and that is really a lot of power in a heater because any defect will overheat and melt. The contacts in the thermstat are apparently rated for the load but are poor quality and they can't take endless cycling with that much power. There is a thermal fuse built in which is good and probably explains why some units stopped making heat but continued to blow air.
I rewired using 14 AWG marine grade wire, crimped and soldered connections and a heavy cord and plug. I reconnected the thermal fuse but took out the thermostat and switch. That removes the problem areas completely.
A few weeks later, I ordered another unit and rewired it with a $14 HVAC contactor. This contactor is designed for repeatedly cycling a load. Now hardly any current goes through the thermostat and switch because they only power the contactor and fan. As before, I upgraded the connections and wire. See my photo. Now this is a 5 star product. Too bad this company ruined their product trying to save a few bucks.
These modifications are not something you should attempt unless you have electrician skills.
I am using an extension cord for power and I read the warnings, but what else am I going to do? Since, as sated above, the heated blows warm air instead of hot air, then the power requirements should be less. The heater is using less power to produce warm air and not hot air. An extension cord may not be the best option, but is shouldn't be a dangerous option. Just be sure that you use a good quality cord and maybe a cord with 12 gage wire instead of 14 gage.
I bought my greenhouse to keep stored plants (plumeria) from freezing in the winter rather that growing plants. I have a big lack of storage place for
my plants elsewhere. Anyway...I am very happy. Hope my review was a help.
