My old propane heater is on its last legs and I plan to replace it with a heat pump. I've narrowed the choice down to two candidates...the Hayward HP21404 and the Heat Siphon 575HP.
I am a DIY sort of person and am really impressed with the videos on YouTube for diagnosing and repairing the Heat Siphon. They would make it easy to maintain the Heat Siphon myself.
Does anyone know of similarly detailed information (manual/videos) for servicing/repairing the Hayward heat pumps?
