How have you got on with the hot tub heater? Any success??

Now that its getting quite frosty out there, thinking of going down the very same route.

Hello Nathan.

I have spoken to electrician and connections are ok to use via a fused switch.

The only concern is the plumbing side of things .

The outlets supplied are for fixed plumbing and I would need to put flexible hoses on.

The pump has a flow switch inside which means it will cut out if no water moving through, which is good.

Another problem may be if the pump has enough power to be able to draw the water up through the top of an upright tank approx 1.2 m. Also if it has the power to then return the water back up into the top of the tank.


If not then it may have to be connected from the outlet at the bottom which would mean splitting the supply between the heater and normal pumps and switching it between the two when needed.

Any input from others would be welcomed.

Cheers

Its sounds a bit faffy to get it started, but think i will soon place my order for one. 2 me it still sounds better than cutting into my tank.

Im now thinking mount it on a plank of wood that can quite easily sit on top of tank. Removable and easy to store when not needed. If the pump isnt powerful enough, i wil get a cheap Chinese pump on ebay to  put before it with a cheap analogue flow switch.  All mounted on board. The pump can then feed into hot tub pump.  Plastic pipe fixed to in/outlets then plumbed into push fit fittings, then connect to suitable hose. (Similar to how i use my submersible pump for my trolley)
