Rear of motorhome cold while traveling.

There is/was an add heater matrix that could be run via the cab heater,into the rear seats

My Swift MH has a Heat Exchanger under the front lounge seats which allows me to heat the hab' area from the engine while driving.   This equipment came as standard.    So much for all those Swift knockers who are always having a go at Swift.

Are there other makes of MH who have a similar system?    Do the German vans have this?      Probably a very expensive option!

Doug, as stated, a lot of vans now have this system, but as its a Truma 'system' perhaps this is why it isnt fitted as part of a whale system.

i dont know if its possible to fix, but in simple terms, the regulator and rupture proof hose are there to cut off the gas supply from the heater in the event of a collision....they were previously marketed as CS ('crash safe'....)

i would have thought that this type of regulator/hose combination would provide similar protection as its not really to do with the heater, rather the cylinder.

perhaps a call to Whale might help...

some systems, primarily ALDE, as in Bill's van fully incorporate heat exchangers to make use of otherwise wasted engine heat to warm both cab and to heat a tank of water while en route...

some also work in reverse, taking heat from the ALDE boiler and warming the engine prior to departure, allowing for instant engine warm up and subsequent cab heating.

i think there are heat exchangers that can be cab fitted but nothing to do with a separate MH heating system.

a little more from OAL on the heat exchanger thinking ....a 10 uear old thread but a lot of still relevant thoughts..

In 1976 |(forty-two years ago) (she says, hardly believing it) we hired a motorhome from somewhere in Essex and set off on a four week trip (which turned into nearly six weeks) to Prague setting off in early September.  There were two couples, and one three year old. 

The motorhome had some sort  (obviously advanced) of heating. (I have no idea how it worked, but it was warm)..... which heated the back so much that we had to open some windows, even on the way home in October.  Can here really have been so little progress since then that passengers in a (possibly) £50,000 plus motorhome have to be cold whilst travelling?

Stand alone Webesco underfloor heater would fit the bill, and work without using up gas cylinders !   Travelling with gas heating on does use up a lot of gas, even if you use auto gas.  

The problem with Autogas is that you can get left with butane residue in winter that will not evaporate in colder weather. 

Not to useful if you are a winter mhomer !  

There are kits which use the heater coolant  to warm the Motorhome on the move.  This ok if you are continually on long runs. The major problems nowadays is that the vehicle particulate filters can be very fussy if the engine does not get hot enough To to allow regeneration.  The extra coolant can slow down the warming up process of the engine.

my Fiat takes a good 10 / 15 miles to get to a sensible engine temperature ie oil temp of about 90 / 95 deg C.

The heater is warm by 5 miles, but all you are doing is robbing the engine of heat delaying the time to get to working temperature if used in cold weather.

Doug, yes I have heard of this and, from what I have read, this seems to be a 'rule' to do with UK build regs?....ie 12v systems go off when the engine is on...

this is not an issue with our van, or other continental models...

as a quick test, before you buy all the kit, start the van, turn in the gas, try and fire up the heater and check what the fan does....

or do it the other way round...fire up the heating I gas mode, ensure the fan is running, then start the van.....if it goes off you have your answer and may ay need to check with the dealer re thise regs I mentioned..

something to do with NCC?

good luck.
