Kellydean Posted August 18, 2018 Report Share Posted August 18, 2018 I'm looking to use a 5-foot tub that was once used for a 220 volt heater and pump. The brand is Great Lakes Spas. I am thinking about buying a softub heater and pump which is 110 volt. Will it work? Quote Link to comment Share on other sites More sharing options...
mrwrick Posted August 18, 2018 Report Share Posted August 18, 2018 Check with the forum here, but my opinion is that the change to 110 (120V) will simply reduce the functions of heater and jet pump to either/or. When jets are on heater will not be. Once jets are off heater will function. I have a 110 v. older spa and that is exactly what it was designed for, as opposed to the 220v. model in which both circuits function together. Unless you cannot enjoy a spa as temperature slowly drops when jets are on you will find it is fully functional in both cycles, either/or.

mrwrick Posted August 18, 2018 Report Share Posted August 18, 2018 I should add that if the spa was originally wired and circuited for 220 there may be some modifications of the circuitry, relays, etc., that are necessary in order for the reduced voltage pump and heater to function and to not burn out your pump or heater with the higher voltage the circuitry may draw if not modified. Do check with a professional. Quote Link to comment Share on other sites More sharing options...
Kellydean Posted August 24, 2018 Author Report Share Posted August 24, 2018 I was simply going to only use the softub heater and pump and not use 220 at all. Go directly from softub unit into pipes on older tub. Think that will work? Quote Link to comment Share on other sites More sharing options...
