One of my last portables had built in heaters with a switch on the machine, so you would heat the water up first, but could also leave it heating as you extracted. With the inline heaters it obviously heats the water as you extract but is not in the tank, is separate so has its own cable.
Alltec say that the Evolution should run on 1 cable for the twin vacs and pump, with the heater having its own cable, so 2 cable max. They also say with the Advance and three vacs and pump needs 2 cables, so with the heater too, it is 3 max.
Cleansmart say that the Airflex Storm requires 2 cables for the twin vac and pump, and a seperate one for the magna heater. so again three.
So all in all, discarding the heater with all machines, as it has its own independent cable,
The Alltec Evolution needs just 1 cable to run both vacs and pump.
The Alltec Advance needs 2 cables to run the 3 vacs and pump.
The Airflex Storm required 2 cables to run the twin vacs and pump.
I just don't like the idea of having cables all over the place, it also makes it look like you are using an awful lot of electicity.
I know the Airflex Storm has more powerful vacs than the the Alltec Evolution, but requires 2 cables as standard, however in reality using the inline heater will be necessary because you don't want to be just using it as it comes out of the tap, do you.
Is this how you guys that have these machines or similar run them, with the inline heater working all the time as you extract?
