I have been looking at these diesel heaters as a heat source for the shop for a while and finally found one that had a feature that caused me to pick one up. The Hcalory TB2 has an auto on/off feature so it can turn itself off if it reaches the maximum temperature.
Right now I'm running a test to see if i can get 48 hours out of 6 liters of diesel maintaining 66⁰ set temperature. The highest it will go is 72⁰ before it shuts down to standby mode and it will start up again at 60⁰.
When the heater reaches 66⁰ ambient temperature the heater slows down to a very low level and just maintains that temperature until it needs to output more heat or it hits the upper limit. The actual room temperature is actually closer to 63⁰
The clicking fuel pump is noticeable but not horrible. Not a hint of burned fuel or any smell at all after the first few hours. The CO detector is at zero.
The phone app is really nice..... Very much a nice addition.
Another really nice feature is the low exhaust temperature. I have not seen the pipe go over 220⁰. I put a 1-1/4" pipe with a flange through the wall and wrapped the exhaust in aluminum screen to keep it off the walls of the pipe. The flange has yet to get above 130⁰.
Shop heater math
I was using two electric oil radiators to keep the shop between 40⁰ and 50⁰ for approximately $75 or more. Warmth came from two infrared heaters not included in that calculation while I was present in the shop.
This heater may actually make it to 48 hours on $5 in diesel while maintaining 66⁰ (63⁰ actual). That's $76 a month for comfortable temperatures.
So far I'm really liking it.
