Additional rear heater pics

Hi all

Recently fitted a heater into the rear of my 110 CSW.

Got it from T7 designs, good quality kit.

Runs off the cooling system, not stand alone. Nice improvement all round in the cab, especially the back.

I might add ducts and vents to it but not sure yet. Got the 3 speed switch from cbsonline. Added 2 resistors for speeds 1 and 2, 3 is full power.

Here's the pictures

I'm assuming this is a 200 TDI. Would the extra pipe runs and matrix not put a bit of a strain on the water pump?

300tdi

Less than half a litre extra coolant so I can't see it stressing the pump. Time will tell I suppose

No - the coolant pump runs at something about 1.5 x engine speed, it throws coolant through the engine very fast and in large quantities, the small bore pipe and matrix he has added it not a lot to worry about. Compared to the main radiator hoses and through the whole radiator it's a walk in the park.

Remember the pump is pumping a sealed system so pumping loads associated are a lot less as it's a push pull system, if it pumps water out, it's being forced back to it.

On the old series camper conversions they used to run pipes all the way to the back of the conversion via a big heat exchanger - no bother.

I never thought of it like that - good point!

i want one lol

Plus the pump is pushing water through two heater matrices in parallel rather than just one. That makes for less resistance rather than more, just like those electrical resistance problems you may remember from school science lessons.

linkys, I likes the look of that....

Very quick delivery. Seems a decent little heater. Making a difference so far but not as hot as main heater unfortunately. But it is a tiny little matrix!

I was amazed at the vitriol dished out to someone regarding this sort of modification a while ago, so I'm glad that this has been a success.

Very interesting. Did you buy a kit of parts from them? I can't see one so how did you know what to order or did they advise?
Thanks.

the winterised military rovers used to have radiators fixed to the rear tub sides and plumbed from the heater system.... toasty

cheers steve

i guess the ideal would be a load of copper piping under the tub making it under floor heating!

I bought most of the parts from t7. Heater, pipes, clips and t pieces or y pieces Chose this heater as the dimensions fitted under the rear seats. Could go bigger but hen you'd have to fit it somewhere else. I liked under the seats.
The heater switch is just a 4 position switch from cbsonline. I got some resistors from ebay to make up the intermediate speeds. You can buy them with built in resistors but they just cost more. This way I can choose how fast each speed will be.

I like the underfloor heating idea but think the airflow would make it a no go er?

I have considered insulating the feed pipe to the rear heater as it is a couple of metres long running along the top of the chassis, will see how it goes.

The insulation will only be about a fiver from diy store.

Was getting complaints from my daughter the other day now that it's getting a bit colder out. I was thinking of a little electric heater - any good?

Another idea I'd not considered, why do these not come to me when in thought of warmer cabins?

The extra heater matrix and blower sounds like the most effective option but it sounds like a lot of work and I'm really lazy.
The electric fan heater sounds like a big current draw for little output but I'd like to be proven wrong so I can get one too.
Anyone got one that does the job?

depends on the power draw / output / alternator fitted

i'm taking my battery off once a week for an overnight charge already (is a series 3 though) currently running a 340 watt veg oil heater and the commute to and from work is now in the dark with lights on prob means i'm pulling close to 40 amps already

if your doing higher miles, or daytime commutes you could prob get a fairly high output one that would do the job and not cause any issues.... what sort of loads are u already running?

cheers steve

Ive got a standard def 90 so not sure what it's pulling. I've got a small cabin with the 90 and a short enough run into town that it only starts heating up when I get there

I was thinking a small 150 watt heater would do the trick. What do u think?

Hmmm the electric heater might be best for me then, I've just had a high output alternator fitted

How much was the alt?
