I’m re-building a pool – going from larger to smaller(<15K gallons). Also adding a heater, ozone and SWG(all Hayward) to my equipment which has a Hayward 1.85 THP VS pump and membrane filter. I don’t want to add control at this point. I read some of the discussions on how to do a bypass. I was thinking that with 2 3-ways valves, one on input and one on output of heater, I could effectively create a versa-flo like function. Ideally the flow rate of water thru the heater when not in use could be reduced to let’s say 10% by setting the 3W valves accordingly to allow only small portions of the flow in/out of the heater. Likely the heater will not be in use for the summer, which is 3-5 months here in Southern Cal. The companies with these pumps say that the reduced flow will prolong heater life by 3-5X. Will this work? Or maybe I just 100% bypass the heater for the summer?
On a related note, the heater will not fire when flow is below some number( about 1500GPM I believe). Can I use my VSP to effectively turn the heater on/off just by reducing the flow rate in the VSP? I could imagine a system where I remotely control the speed of the pump and the settings of the 3W bypass valves to reduce the flow thru the heater when the pump flow is below the minimum. Would the internal heater flow detection work if the heater is 90% bypassed?
I’m not a pool guy. But I am experienced doing code-legal DIY electrical and plumbing on multiple residential property re- builds. Any thoughts welcome.
