How Long Did Your Hotblast Circulating Fans Last?

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

I bought one of these from TSC last year.My fans run 24/7 for about 7 mo.a year.No trouble so far but they do seem a little hinky(cheap).Just wondering if anyone had to replace theirs yet?I oil it like I'm supposed to but they do seem cheap.

BTW I like this furnace a lot but it did take a long time to learn how to burn it.

I can't answer specificly about the fan on the Hot Blast, but if an electric motor is kept lubricated and clean of dust accumulation, it should last many years..

The big issue I think is the dust/cobwebs/flyash environment that these motors and fan assemblies operatate in... The dust etc coats the fan, coats the cooling holes and passageways, then the electric motor starts to overheat... Heat softens, then destroys the thin insulation on the wire windings in the motor, then.... mushroom cloud and no more motor.

I recommend a pass with a vacuum every week or so to keep the cooling vents clear, and maybe every month or two, shut it down and clean the fan blades with a q-tip or similar device. Or what ever works for your motor and fan.

I have fan motors that are over ten years old, workng fine,, I treat them as I describe above.
