Anyone know what KW output the d3/4 webasto pre heaters are? Thinking of fitting one to central heating in static caravan, need a min of 5kw really.

I reckon you are talking 3 to 4 kilowatts . I have the thermotop pro 90 fitted on my landy and at full chat it's 9 kilowatts I believeAnyone know what KW output the d3/4 webasto pre heaters are? Thinking of fitting one to central heating in static caravan, need a min of 5kw really.

Then IMO there is a problem with the cooling system cos webasto auxiliary heater is made as to stop when the coolant temp gets to 76*C so if i still works the coolan temp is below thatOn the D3 in winter, it is not unusual to drive 100 miles and when you get to your destination, the fbh is still running.
that's how mine does, retrofitted thermo top c with oval timer fitted by webasto lincensed personnel and that's how it's set by them, i asked them why the 30 mins as i was curious at that time and they said that it's the best for the unit to last long ... AFAIK there is a difference between those made for vehicle auxiliary heater and those for caravans/boats etc... what i meant was to no use for caravan one which was dedicated for car auxiliary heater cos these are dependant on the vehicles ECT input.... there are special kits for caravans/boats with own analog water temp sensorI am not sure where people are getting the 30 min max run time from? lots of people use them on boats etc

IMO on a modern vehicle like the D3 if the thermostat and cooling fan works well once it went up to working temp(aroud 90*C) it should not fluctuate much with engine running... when the engine comes out of load so does the cooling fan.
