He made mention of without doors it wasn't enough but I thought he had doors.
Just to clarify the confusion.
1 . I replied to another member that he does not need heater if the winter is mild and he is not planning on installing doors.
2. In my case when we get minus 40-50, aquhotheater is ok, after about 30 mins ride but p500 lacks small bypass circuit like 700 and 1000 have and fresh heat comes only when thermostat opens in p500.
So for now solution is get propane golf cart heater and use it to warm up cab before ride or when the engine is off and I need comfortable temp in my cab.
Later this fall I will work on bypass vavle that would be very good must add on for those who are planing on liquid engine fed heaters , that would give instant and better heat
