During this lockdown period I am sure I am not the only person to do something that is totally unnecessary. This is just one of those things. The Intex Purespa hottub is a great product that we have very much enjoyed using over the last year, summer and winter. But to be able to enjoy this spa you have to make sure that the temp of the water does not drop below 6 degrees or the spa will not turn on and start to heat up. This is not a problem in the summer months as the water always stays...
