We will also explore the simple solutions to these causes for Mr. In this section, we will take an in-depth look at the possible causes for common Mr. Read our Mr Heater Buddy troubleshooting guide to solve these issues ASAP. Heater Buddy keeps going out, igniter doesn’t produce a spark, pilot won’t light or stay lit, burner face to ignite, delayed ignition, burner backfiring, heater smells like gas, control knob won’t turn, abnormal noise, and heater not getting propane from tank. Heater Buddy problems that users face are Mr. ![]() Propane is nearly 100% efficient so no exhaust is needed and 100% of the heat energy stays in the van.The common Mr. Webasto- Air Top 2000 St- deisel On low 3,100 btu/hr *1hr/.3 gallons=10,333.3 btus/gallon ĭespite diesel larger btu/gallon, its hard to direct a large enough percentage of btu from the exhaust as it exits the van. ![]() Exhaust has a lot of heat and must be directed out of the cab so how much heat is sucked away from exhaust and directed into cab? Sounds like a mini jet fighter taking off. You can hear it loud and clear from like 5 ft away. On low according to mr heater fuel consumption 4,000btu/hr*1 hr/.044 gallons=90,909 btu/gallonĪt 100% efficiency (which it should be very close to) 91,000 btu/gallonĭiesel= about the same as propane- $2.99/gallon here in san Francisco, maybe less out in the Midwest 139,000 btus/gallon The guy turned his on for me. My CO detector has never gone off but I have some serious "weather proofing" issues. IF less than 96%, CO is emitted which is lethal, so must have CO detector on board. Co2 is only byproduct besides h20 if burned over 96% efficiency. Propane=2.99$/gallon where I live has 91330 Btus in 1 gallon and mr heater buddy claims its practically 100% efficient, indoor safe and has oxygen depletion sensor. And after seeing this post I ran some numbers: Guy I bought solar from tried to sell me his. Same idea, not as well made and twice the size, but a lot cheaper than a Propex. If you've got more room you can get the smallest versions of the RV furnaces for around $300 on eBay. Just set the thermostat and you're good to go. They're basically a tiny version of a home furnace, with an external air intake and an exhaust, so there's no worry about fire, carbon monoxide or water buildup. ![]() They're expensive, but tiny, efficient and safe. If I were living full time in the van I'd break down and get a Propex. The nice thing about the heater is in the morning it only takes a couple of minutes to get the van toasty when I get up. When it's time to sleep the heater goes off, the windows go up and I go into a warm sleeping bag. I use one, the way I do it is I open the front windows an inch or so for the required ventilation, then get the van nice and warm before bed. The more you run the heater the more water you get built up in the van, which can get into the walls and cause rust. The combustion of propane produces water as a byproduct, no way around it. You can get detectors, but how comfortable do you feel trusting your life to them? Finally, there's water. Of course you have concerns about fire, which are easily dealt with Then you have carbon monoxide. There's several separate issues with using something like the Mr.
