Title: Daft idea or not ???
Post by: Ian101 on February 02, 2012, 10:22:05 pm
I will try and explain this idea the best I can  :)

Poss daft but seen dafter ones on here though

Whilst loading reels and poles into van this morning I had engine running and realised a lot of heat from exhaust .... so would it be a good idea to make a metal pipe that wraps around length of exhaust and have a small pump that pushes water thru this pipe from bottom of tank, thru coiled pipe and back into tank on a continious loop.

Water wouldnt get piping hot but would still be warm.

When tank low just turn small pump off.

It'd be easier to "T" into your heater matrix & run a coil of underfloor heating pipe or similar round inside your tank,...

I've thought of this; there's a LOT of waste heat from an engine - with wide enough pipes (28mm copper) and a bit of thought you might be able to get it to run through convection alone.  With another bit of thought you could run a bypass through a normal diameter pipe from your normal pump back into your tank.

Obviously never got round to it, so let me know how it goes.

I was worried for a moment that you were thinking of running an exhaust into your car  ;D

But, this is not as bonkers idea as it sounds, the water not the exhaust gasses.  Could be some mileage in it somewhere, although it would need a circulation pump like you'd use on a central heating system I think, rather than the type of pumps we use.

What about copper tube, low diameter like gas pipe?  Wound around the down pipes, with anti freeze added as well.  Then up into the van and connected into plastic under floor heating pipe, that's flexible sort of and tough to break, will radiate the heat very well in your tank.

My old man designed a decent heat recovery system from his log burning fire using two flues many moons ago, works very well.  I'll annoy him tomorrow with this little conundrum  ;D  I also happen to have 30m of underfloor heating pipe knocking about in the shed  ;)

Pit falls.

1 Some Pikey robs the copper  ;D and your Catalytic converter
2 The engine will need to be running to keep generating heat (ish)

I still like the idea though  :)

Just because people tried and failed does not automatically mean CleanCare will!

It was discussed on Matts cleaning forums around christmas time.

Matt said he was going to speak to his garage mate about it.

The Prowler TM carpet cleaning machine uses a heat exchanger around the exhaust to heat the water, takes it to 70deg in seconds.  It's not a daft idea, it would just take some working out.

How much condensation do u get from having an immersion heater in tank

It'd be easier to "T" into your heater matrix & run a coil of underfloor heating pipe or similar round inside your tank,...


thats the way to do it. ;D

Was talking to a br some time ago who was a mechanical engineer and fixed somebody up with a system like this. Used a coil from a central heating tank. Was like a 30 second conversation and didn't have time to ask how well it actually worked. Thought that was an excellent solution, if it works. Should work.

Quick look round the web has the exhaust temp running at around 500°C - plenty of heat there.

So, harnessing it is the tough bit.  Spoke to the garage last night - was in for a bulb - and they reckon a tube coiled round the pipe would do it.  The problem is dealing with 500°

Ignore the naysayers; there's a bundle of free heat there.  Find a sensible way to use it and you'll be quids in.
