Str8rippin Posted November 4, 2011 Report Share Posted November 4, 2011 So Just bought a Hot Tub/Spa and i fired it up and it took over 8 hours to get to 35 Degrees Celcius (95 degrees Farenheight) I Figured this is rediculous so i worked out a way to heat it much quicker and without using any power apart from pump Power (No Heating Element) All I Have done is bought a Rinnai Tankless/Instantanous LPG Hot water heater off ebay for $300, Connected it to a 9KG BBQ Gas Bottle, And Run Garden Hose From The Pressure side of the pump into the Inlet, and out of the heater into the suction side of the pump. The Water heats up within 1 Hour to over 100 Degrees, I Have An Rinnai Electronic Controller which keeps it heating at 42 Celcius (110) farenheight. This Uses little Gas Being a 5 & and half star gas rating unit, And i only need to have it on for 1 hour then i can either use the old slow electric one to keep it warm or occasionaly turn it on again to pump Hot water straight in. Reasons Why this is alot better than ANY other Type of Spa/Pool Heating 1. Gas Bottle = Know how much your spa is costing and how cheap is gas? 2. From Cold to Hot in 60 Minutes (Beat That Electric Element) 3. Whole Setup Cost Under $550 Or you can a Normal Spa GAS Heater From Pool Shop Start At Around $1500 NO THANKS! 4. Power Bill at End Of Month = inted of :@ 5. Breaks Down? Easy to repair/replace Domestic Tankless Water Heater NO The chlorine will not damadge the Unit, Heres Some Picys Of The Setup Oh And Added Cd Player Quote Link to comment Share on other sites More sharing options...
