Hello. I just had solar panels installed. I have a 2-speed pump, and the solar controller is set up to switch the pump into high speed when solar heating is needed. When my pool was set up, the installers set it so that the salt water chlorinator only runs in low-speed mode. Their explanation as to why wasn't a great one, but at the time it didn't matter.
Now that I have the chlorinator, it does, as the pool will be running more, and in winter a lot, in high-speed mode. The tech who installed the panels had many misconceptions about pool functioning, so I take what he said with a great degree of suspicion, but when I asked him about whether to have the chlorinator run in high-speed mode too, he said:
- The amount of chlorine produced is similar in high and low speed modes, i.e. it is independent of the speed of the pump
The hotter water will consume more chlorine.
I read a post on here that JasonLion said that hotter water does use more chlorine. However it was my impression overall that UV consumes chlorine. My fear with turning the chlorinator on in high speed was that if the output of chlorine went up because of the high-speed, and in cooler/less sunny months the heater would run more, that my chlorine could quickly get high with a temperature drop. But if the output is the same, I will just need to to adjust the chlorine % just a little. And more chlorine consumption because of the higher water temperature balances a little the less chlorine consumption because of less UV in the cooler periods.
Would you guys agree that I should have the system settings changed to run the chlorinator in high-speed mode too?
