Hi

Any help or advice on is it possible to run the diesel heater into Truma heating duct that goes to Battery/Tanks and garage please? with main flow into the living area of van.
This our first van with a Truma heating system and not that impressed with heat/blow flow all around the van, Diesel install would be for trip to Norway/Sweden and it wasn't that warm in Wales when tested!! our previous vans have had Alde systems,
Thanks for your help

Yes you can a couple of Funsters have done it, you need adaptors for the trunking as the diesel heater is 75mm internal and I think the Truma is 65mm.

The Truma heaters are pretty good if installed properly a lot of manufacturers cut corners. Our 7.5m A Class gets toasty warm with the Truma most of the time the fan is on low you can't even hear it.

Hears a search result for Diesel Heaters.

Do you want to use just the diesel heater full stop or be able to use your Truma to blow cool air in summer heat if it has that function?
 
Strangely I had this thought as well.

Think I’ll do as Two on Tour has done and I’ll just blow the hot air from one outlet under the bed straight down the van 😊

Unless he has evolved it as he’s known to do 😊

I've fitted an additional Webasto airtop heater to our PVC and have 2 separate outlets, one under the dinette seat and one in the bathroom which points to the rear of the van. We still had problems with the Truma dump valve triggering as there wasn't enough heat getting into the area where the dump valve is located and also the water pipes that go across floor under the bed. The original Truma ducting gets to all these locations. We have been on a 5 week ski tour in the Alps and the Webasto saved us using the gas all the time when off grid but has its limitations due to lack of ducting in the rear of the van.

Retrofitted a Webasto EVO 40 diesel heater to a 2016 Hymer Exsis-I

Just wanted to share this, since I was unable to find any information similar when doing this project. Me and my family use the MH a lot during the cold winter here in Norway. It can get colder than 30 celcius below freezing, (-22 F), but normally around -10 celcius (14 F) during winter. The...

The heater outlet into our van has evolved by changing from a 75mm to a 90mm outlet and changing the pipework to the heat exchanger inlet of the heater again to 90mm with a flap to throttle the air in if required to increase the heat output.

For anyone feeding into Truma ducting of any length and with multiple outlets, needs to remember that air will always take the route of least resistance, so you may need to partially close off outlets to get the heat where you want it, a bit like balancing radiators on a home central heating system.

Same as ours in our Hymer motorhome.

A contrast to the heat output of our Truma 3002 in our Hymer caravan coupled with the poor heat retention of of walls. Yes, we can stay warm. But the 2000w electric element in the Truma 3002 need the additional gas input when cold or windy. Along with a 500w electric radiator oil the bathroom.
 
Thanks for the input:giggle:

My idea was to try and keep the cavity between floors warm so reducing chance of Lithium/grey&fresh tanks/boiler dump valve and garage having problems if below zero for prolonged period,
Have many of you taken fuel from main fuel tank? or just using 20ltr marine tank?
Anyone recommend someone to do supply and installation? not worried about location as would prefer a recommendation and do the job correctly once..
thanks
