Solar Pool Heater Valves

Solar pool heater must have a vacuum release valve 7 installed on or just off the roof.

Solar pool heater valves.

Isolation valves in solar pool heating systems may be standard ball valves or high quality two way valves from pentair jandy hayward praher or others. Includes led indicators that shows status of system operations. It automatically maximizes solar heat collection by actuating a 24v valve when there is solar heat available. The main solar pool heating page aleady showed a diagram of a manual system using a single control valve and a check valve.

The auxiliary heater is completely optional with solar pool heaters but most people with a spa want a traditional heater to quickly heat a spa on demand. Some people erroneously believe the relief valve in a solar pool heater is there to relieve excess pressure and heat. These valves control where water is returned the the pool. The following two diagrams illustrate how a manual system can be done using three identical manual valves.

Winterizing pools in cold climate locations should set the valves to bypass when closing down the pool for the winter. Manual control using three valves. As the pump stops and the system wants to drain back the function of this valve is to open on negative pressure and allow air to enter the collectors so that the weight of the water pulling internally on system components does not internally crush. Solar pool heating 3 way valve solar bypassed your valve configuration may be different on the ground rather than the wall or may not contain all of the pictured valves.

Not using the heater if the heater gets very little or no use then it should be bypassed. The pump still runs several hours a day to filter the pool but from noon until about 6 00 pm the timer turns the pump on and off at 1 2 hour intervals. Automatic diverter valves use sensors to detect temperature and automatically direct water to or away from your solar panels. To solve this i installed an outdoor timer to my pool pump.

This gives the water in the solar heater time to heat up before it goes into the pool. Hayward solar pool heating control system comes with 2 by 2 1 2 inch 3 way valve actuator and 2 pc sensors. Two valves control the flow to and from the solar collectors and one allows for. Can be controlled with automatic diverter valves.

While every solar pool heating system includes a manual diverter valve for managing water flow automatic valves are an upgrade. Bypass the heater until the pool is clear. Because a solar pool heater is an open loop system expanding water and air due to heat easily escapes back to the pool and no pressure relief is necessary.
