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
