I'm halfway through my pool/spa plumbing equipment update and relocation, having purchased an existing house with poorly located and very aged and failing equipment.
I have successfully completed the pool - pump, sand filter and SWG - which has independent filtration and heating lines, so that was relatively easy to get my head around, but I'm struggling with the spa. Heat pump being wired in this weekend by electrician.
Spa/Pool water is completely independent systems - there is no common plumbing between the two.
My concern is only having 1 x 50mm (2inch) suction pipe from the SPA, and setting up eithrr a GAS or HEAT PUMP heater - how do I maintain the right flow rate through the heater, whilst maintaining high flow rate for the jets? The existing setup had the 2hp pump plumbed directly into the gas heater with no bypass - I have a suspicion this is what killed the existing gas heater as everything else worked?
I understand the logic behind a bypass valve setup on a heater, but given the heat pump will likely have to run for a few hours each day to keep the SPA hot, is this likely to be sufficient?
Ideally, I'd like to have a filtration/heater pump and then a separate booster for the jets - noise is a factor and don't want a 2hp pump running unnecessarily because of this reason. Cost is not overly an issue if I can achieve a good outcome.
Is this possible with just one water line, and maintaining the heater on whilst in the SPA?
I can't figure this one out. Any help would be appreciated.
