I bought a used acrylic hot tub shell that I plan to sink into the ground in the backyard. The plan is to heat it with a tube/shell exchanger off my thermal store, with a main pump for the jets, and a circulating pump for the filter and heat.
I plan on putting the pumps & controls in my workshop which is about 4m away. I suppose this is too far away for an air switch, what is the best way to get around this?
- anyone know a good place to buy jets, and other hot tub parts?
- if the system has two pumps, I assume they need to be in parallel. Does one need check valves to prevent back flow through the reciculating pump when the main one is on?
- any ideas for the best way to insulate it from the ground?
