Solar Heating Pump Size?

Hi All,

I just purchased a solar pool heating kit for the pool and need some advice.

The Kit is 28m2, The Pump I have already on the filter is a Onga PPP1500 (1.5hp) connected to an Onga P25 Sand Filter.

The pool is fairly small 35,000lts, and i believe the pump and filter i have already is overkill for this pool, I think the pool guy told me it can do a pool 3 times the size.

Anyway, What i need to know is, can i use the exsisting pool pump to run the solar heating also? Is it powerfull enough Or do i need to purchase a sererate pump?

It will have to push the water up one story to the roof which is about 15 meters away from the pump.

I had the extra solar provisions installed when the built the pool but it's pretty cold all the time, so i was thinking of not using it and just using the pool filter to heat the pool as it would be cheaper than running two motors daily. I could always put a diverter inline so i can stop it flowing to the roof if needed.

Any other advice??

Also what silicon should i use to hold down the matting on the tiled roof?
