DO NOT BUY ONE OF THESE!

I would call them a flaming ball of shit, but they actually won't fire.
These are Enerco (several brand names - Mr Heater is one) and we also have several DESA (again several brand names - Master is one) and while the DESA have never been particularly reliable, these fucking Enerco take the cake.
We bought 3 of these Mr Heater 175000 BTU units 3 years ago. They've all had the hoses rot out inside of them, with various small problems, bad pumps, bad ignitors, etc. They all get cycled through and repaired (I think we have about a dozen kero heaters all similar to this). We finally have gotten down to what's broken now?
ALL THREE OF THESE MR HEATER'S! And they are the newest ones.
All Chinese parts inside, it's either the flame sensor or the circuit board. I'd kill for a Taiwanese made part. I'm betting money that the cheap white chinese circuit boards are fucked. The flame sensors look good on an ohm meter, but I don't know for sure.
We did get one to crank up and run for more than 5 seconds without throwing an error code, but either the pump or nozzle is bad, because it burps and spits kero and doesn't smell right.
Just dropped a $130 for replacement parts trying to get them back into service, but damn, the Ford Pinto was more reliable than this.
