here's something i made Thursday .
and ive used all friday =Saturday,   i got the idea while looking at the perfect heat cc  didn't fancy the cleaner but liked the idea of the coils heating the water first before the in line heater. anyhoo  i bought the copper tube from a plumbing gaff  its called 8mm micro pipe 10 meters long 33feet ish [i payed £15in vat] i coiled it round a 6inch paint pot  any more than 6inch and it wouldn't heat well any less than 6inch and the motor might over heat .
 then i joined  them together and broke into solution pipe and joint to each end of the coils .
NOW i wasn't sure how or if this would work but believe me its very good .
maybe not as instant as they say  but pretty dame good.
before i made it i ran the cleaner for an hour then measured temperature of motors [pretty hot]
then checked after with coils on and was exactly the same.
now i know theres some nut jobs on here just sitting waiting to pull peoples ideas to bits and thats fine [takes all sorts]  but i think thats the point of this site  yeah        thanks for reading

Very ingenious, attempting to use "free" heat that would otherwise be lost.

So how much extra heat are you gaining from this John?

Have you noticed any drop in flow rate, because the pump now has to pull the water through an extra 10m of pipe?

I'm presuming your machine has an inline heater after this home-made arrangement?  Or you use an external heat exchanger?

[Colin Day]

I think that's pretty brilliant mate

well it dosent seem to be loosing any pressure and if it is its not much
mind you i dont want to get tecnical but the hotter your water gets the higher your pressure gets.
  and my cleaner has a in line heater  cheers fella

thanks for that  i may be pretty thats true but brilliant no   well ok then

I've looked and looked at the pics and have to say well done on something 'simple' that makes use of wasted energy ie the heat off the motors.
I did wonder why (to prevent pressure loss) you didn't put the coils after the motors but clearly that would require far better connections than just jubilee clips than required on the inlet side!!
Have you measured the temp of the water after it has been through the coils?

asked about putting after pump [if thats what you meant] and was told would loose pressure.  but hay who knows first go maybe next time .
 also about temp my in line wasn't the best . ok but could be better .  but it has really inproved now  mind you like i said it dosent happent straight away [5-10 mins] but for £15 quid im happy

[Neil Williams]

Sorry my fault, I meant coils after the pump.
But if you did that you would need connections capable of dealing with 200-300 psi and jubilee clips wouldn't be suitable then.

[Russ Chadd]

Yep thats when things get dangerous... high pressure connections will then need to be involved... im sure the water wont be hot enough to damage the pump... i think its a great idea of using otherwise wasted energy.

So come on... what's the temperature increase at the wand?

[Colin Day]

The hot air exhaust at the back of the Altec is great for aiding in the drying of chair cushions and for keeping your pasties warm...

which pasties are those then colin or is it best we dont know

Cornish ones... Though I do prefer cheese and onion...

ok at the wand well lets just say its a lot better and well worth doing .
im not going to fall into that trap coz it will be different for each cleaner
but what i will say is its got to be better than not having one yeah

[clinton]

Must say it look a great idea mate too..

[Neil Williams]

I showed the pictures along with a spare motor I have in the shed to a friend who is an elect/mechanical engineer with all the degrees etc.
In his opinion you could take it a stage further by coiling closer to the motor and also coiling over the top of the motor to catch the fan heat, he also suggested some fins on there too. He then took it a bit further (don't they always!) with switches etc all over the shop because whilst the machine is on and the wand isn't being used the heat build up in the copper pipes could be quite big, and then with the wand in constant operation you wouldn't gain much heat in the water as too much water flow is in operation.
His answer without all the additional switches would be to have it on constant flow back to the tank. Mind you by this point I was thinking you might as well buy the ready made machine.

Just out of interest, anyone seen the third picture down on this page before?

Would have thought that induction would have been better than radiation ?

[Adam Fearnley]

I have the perfect heat CFR, the coils do heat the water up a decent amount and also help with cooling the motors.  I wouldn't start putting coils over the fans, it could restrict air flow into the motor.  As with the perfect heat system i think the best thing is to have two layers of coil around a motor i.e as much copper surrounding the motor as possible then the water has more time in the coil to heat up.

at no time did i say it was my idea  i said straight way where i got the idea from
but like i said there was always going to be one

[Russ Chadd]

i wonder if you could also wrap some foil tape around the coils to help store the heat? or possibly attract heat?
Its a good idea without a doubt... if someone were to develop it so it was very efficient i would buy this system! i wonder how long you would have to run the motors before the water were to flow warm?
