Anyone know anything about heat siphon z575 heat pump

[Docs911]

I am in the market for a heat pump. Was leaning towards a Aquacal SQ155 (135k BTU). I contacted Poolheatpumps.com and they suggest a heat siphon brand pump (z575). Does anyone know anything about this company and this model?

Thanks

I have a heat siphon. It's an older unit, doesn't get alot of use, but works well when I need it to.
Here's their web site: http://www.heatsiphon.com/
