jeeper Posted July 25, 2013 Report Share Posted July 25, 2013 Hi All Ive recently inherited a spa which has added a significant amount to my electricity bill (4x up). Im from New Zealand and the spa controller is a spaquip 500 (see link) http://www.spa-quip.co.nz/shop/Controllers/Spa+Power+500/Spa+Power+500+Touch+Pad.html So the controller is basic and the whole system will not run without both the heater and the motor going at the same time. We are using a slow release silver compound to keep the pool clear which is working great but means we have to keep the spa on 24/7 in what can only be described as a temp maintenance mode ie the spa flicks on for what seems like a 45 min period every couple of hours to keep the temp steady. The silver requires 75,000 litres of water over it per day to be effective. My Question is two fold. A - Is the more costly of the two system pieces the heater element to run? And if so are there any products that I can run inline in the ribbon cable to bypass the thermostat and keep the element off while the pump goes? Reason being is that I can then just run an old school timer on the plug limiting the pump operation to the min hours per day required to keep the silver working. B - Is there any truth to the fact that shutting the power off at the wall on a spa will decrease the heater elements life? By the way its a 2KW heater and a 0.75kw (280l/min) pump... if it makes a difference. Quote Link to comment Share on other sites More sharing options...
spanoob9 Posted July 25, 2013 Report Share Posted July 25, 2013 I'd guess the pump is more costly in electricity.. They also tend to die faster than heaters. Not sure about B, but makes sense since these spas aren't designed to be shut off constantly. Quote Link to comment Share on other sites More sharing options...
