Welcome to our forum.
I am looking at purchasing a Solana RX spa tub. This is in my price range. This is a 110V tub. They tell me that the only difference in 110V and 220V is that I can't run the jets and the heater at the same time. How big a difference is that? Let's say I sit in the tub for an hour - how quickly will it cool down if it is 60F outside?

I'm shocked to see these replies. 110V is more costly to operate (as mentioned) and generally will not keep temperature in colder climates. 2 or 3 degrees can make a SUBSTANCIAL difference between comfortable and luke warm.The difference between a 5KW heater and a 1.5KW heater is obvious here in Alberta and very uncommon. Maybe if temps only got down to the low 50's would I consider it in an outdoor application.
If the Solana uses a 24 hour circ pump for heating, there will be ABSOLUTELY no difference in heating cost. Yes it will heat at 1/4 the rate, but it's also using 1/4 the power. If the heat pump runs only when heat is called for, that pump will use 4 times the electricity on a 110v system over a 220v system.
