# Pool siphon question

I have a pool that's about 5ft deep in the middle and I wanted to use a siphon to possibly heat my pool. Essentially my idea was to use a black hose, have it submerged about a ft or so in the pool run it out onto the deck where it could be heated and then back into the pool where the other end was submerged say 5ft... Would this siphon be able to work if it essentially ran in a circular loop back into the pool just at a greater depth?

Hi anthony:

A siphon works to move a liquid from a place where its surface is higher to a place where the surface is lower. To move in the reverse direction you need a pump.

You seem to want to move a liquid from a height which is below the surface of the liquid to a deeper height in the same pool. (While moving the liquid you want it to become warmed.) A siphon cannot do that. Imagine putting a four foot hollow pipe between one foot below the surface of a pool to five feet below the surface. Why should this move any water?

Hope this helps.

Regards,
Buzz
