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?
-
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
-
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.
-
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?

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... :D

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
-
Must say it look a great idea mate too..

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 ?
-
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
-
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?

Imagine if you put the coils around 3 motors like a Scorpion or an Airflex you could have a portable TM with only 2 plugs.

well i was at a job friday and they had no hot water surprise surprise.
so i explained to the cuzzy that i would have rather it was at least warm .
but anyway put it in and switched cleaner on vacs and heater .
left about 2minuets
and it was hot im not talking ripping your skin off hot and i had to keep stopping to let it catch up as it where . but not bad not bad at all for stone cold water
lets face it if it where a extracta id have been there three days waiting to heat
its been a week now and for £15 id highly recommend it
theres even being a couple of jobs where the water in the tap was hot and i dident use the heater at all anyway thanks for asking

3 days???? what planet are you from. I can put 40ltrs of cold water in my extracta exel, turn on the heater and in 15 mins its at 50 - 60 deg c

Hi Guys
You can work it out.
A 3 kw heater will take just over 37 minutes to heat 40 litres of water by 40 degrees centigrade asuming no heat loss.
cheers

Doug, if I fill my machine with "cold water" from the hot water supply and it is at 20 - 25 C (never been sad enough to check it) out of an insulated tank, should it not reach 50 - 60 C in about 15 mins?
My point is, the 3kw heater on extracta machines does work. and even if the water was at 10 C your stated "just over 37 mins" isnt 3 days. The half hour is ample time to set up and prepare for extraction.
-
The idea of using heat exchangers around the motors is just to heat the water so its not cold when it passes in to the inline heater... this would in fact take the inline heater less time to reach its operating temperature.
Again i think its a great idea and i wouldnt mind trying this on my new Airflex turbo when i get it.
Copper is a really good heat conductor and if the pipes are wound closer to the motors and then covered with insulation, this would again reduce heat loss.

Hi Guys
Paul, I am a great believer in in tank heating, as you say fill up, put heater on and then prespray, vac and whatever else you want to do and you will have nice hot water.
I also clean under furniture first which normally doesn't need much cleaning so that when I get to the dirty bits I have really hot water.
Cheers
Doug

Another untapped heat source is the van engine ....
anyone whos used a Bane would be familiar ( perhaps others use it ?)
The hot water from the circulating van cooling system is fed through a heat exchanger ( might be just copper coil ) which is mounted inside a large insulated clean water tank .
As you drive the water in the tank warms ... gets quite hot eventually , and can even last overnight ...
Works suprising well on its own or combined with an inline .
