That's why I posted details about temp, etc. I knew we couldn't be the only ones with this issue, since pool therapy is a really big deal on this forum, and thought it might be useful to someone else.

Basically, the solar panel hooks to the pool's filter pump. Water goes from the pool to the filter, then through the solar panel and back into the pool. Some people install the panels on their roof, but we just laid it on the ground facing south. We had to buy an extra hose to attach the solar panel to the pool inlet valve. The hose doesn't come with the panel, probably because different pools need different size hoses. We also use a solar cover (looks like blue plastic bubble wrap), which holds the heat in. Here is a link to the solar panel we used:

It helps that our pool is only about 3,000 gallons (it's a 36" deep pool), so there's not too much water to heat.

It's still worth doing therapy at a pt place so that you get an idea of what exercises to do and how to build on them. Our son did pool therapy for about 6 weeks and we only pulled him out when they moved him back into the gym before he was really ready to tolerate it.

So glad you can start pool therapy, it's the BEST!
