Solar Pool heater - is it even working?

[webguy]

Hello,
I am trying to figure out my solar panels and whether they are heating my pool. First a little background - purchased a home with a saltwater pool and solar panels heating it. It was great when we moved in - real hot right around this time of year. The actuator that lets water through to the roof (panels) rusted shut and I replaced it. It seemed that there was more than one way to put the handle on. I tried two ways over the past month and can't seem to get any heat.

I took some pictures and a video which are below.

What is going wrong? I can hear water moving around in the pipes that go to the roof. I do not feel a temp difference in the water that comes out. Let me know if there is anything else I can do to explain my situation. Thanks for any help.

The typical temperature rise from a solar panel is about 3-4 degrees from input to output so it may not be easy to tell the difference. Your setup looks like it should work and the brown valve you pointed at is a check valve and prevents water from flowing backwards through the filter when the pump is shut off.

What is the filter pressure with solar off vs solar on?

Hi Pintohenry! Have you checked this guide to swimming pool heaters at http://www.indoorpoolguide.com/heating-systems

Warming your outside share with a solar pool heater is a simple way to lower your energy expenses and keep your share warm enough to move all at the same time.
