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.

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?

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

good for you

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.

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

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 .
