Has anyone that has a diesel heater installed had an issue with excessive localised heat build up in the heater unit compartment. Such as under bunks or in cupboards. Guessing that as most are encased in plastic that it shouldn,t be a problem but curious as to how much heat would be generated in that storage compartment. Many Thanks Mike.P

We have had a diesel heater (eberspacher) in our van for approximately 2 years. It was installed in the kitchen where a "half drawer" was formerly located due to an imposing wheel arch. It is about a 30 x 30 cm area. The heater has run all day at times and I have not noticed any excessive heat build up in that compartment area. The access door to the unit is not hot nor are any surrounding surfaces.

Mine draws room air from just rear of the LH wheel arch and the air enters under the fridge to the heater which sits directly under the fridge. The hot exit air is ducted immediately into the bottom of the pantry and then towards the centre of the van from the Fridge/Pantry cabinet. only low down in the pantry gets a little warmer.
The temp in that storage compartment under the fridge doesn't get warm much at all. Doesn't worry the fridge performance.

Michael

I have used Diesel heaters (Webasto) in 3 different vans now and found that if the heater is drawing its cool air from the compartment that it is in then there is not any substantial heat build up in that compartment, however if the cool air is ducted directly to the heater then there is a substantial heat build up in what is then substantially a sealed compartment.

My current installation is under the bed and drawing its cool air from within that well ventilaated compartment, any heat build up would only serve to warm the bed. If cool enough we do run the heater all night.

If you run it all night, wouldn't the noise keep you awake ??

No, the little noise is often more bearable than the cold, and as I am used to having an Oxygen generator running all night for the past few years then there was no noise from the heater.

If the units are installed as per installation instructions there should not be any heat build up. Not withstanding that, the heaters do have over temperature protection, for heater.
