Heater Short Cycling Advice
Greetings all you fine folks.
Having an issue with my 40K BTU RV furnace in my bus short cycling, at a 45 degree outdoor temp (t-stat set at 60), it will run for about 4 1/2mins get it super hot in there then shut off for about 20mins, and in that 20 mins it starts to get pretty cold in there. The is repeats over again slightly annoying to say the least.
I had an old guy tell me the trick to keeping any RV warm is a low amount of heat all the time. Something a WAVE style heater would do or one of those Chinese diesel heaters.
What would you think would give me a more stable temp.
1. Rip out the RV propane rig and install diesel heater at 5K BTU might be too small in a 40ft bus in Montana. Don't look forward to the work)
2. Leave propane RV rig in place and install wave 6 heater under current T-stat (see photo) don't like that ideal as it lacks a T-stat but follows the old guys advice.
3. Remove the 42K BTU RV rig and install a 25K BTU version, with maybe a better t-stat. I vote for this but will is solve my problem.
4. Maybe it's all a waste and because I have all of my windows and stock celling in place, I will keep feeling those wild temp swings. Or maybe my poor vent placement is an issue too.
What would you guys do?
