intercooler

Are you sure? I took a look at the manual for my tub (Hawthorne), and in the US the circuit can be 40/50/60 Amp, whereas in Europe Sundance specify 20/30/40 Amp for the same model tub. Isn't the load (amperage) on a 110v circuit higher than the load on a 230v cicuit for an equivalent power demand? Also, does this mean a tub in Europe will not only heat slower, but the pumps will also have a lower output (less power)? I'm willing to stand corrected but I find this hard to believe as there's plenty of countries in Europe, including Sweden, where it can get just as cold as the coldest parts of the US. I live up north in Norway and in my new Hot Spot Mallorca the temprature drops from 40C to 38C within one hour, this happens in cold weather, -10C. Is this normal or is the heatin element to small? (1000W 230V 50Hz.) Before i bought it the dealer told me that the heater was big enough but I am not sure.

Which brand is it? Maybe it`s normal.

i would say that it is to small most tubs come with iether a 4000 or a 5500w ... i guess one question to ask is your tub a 110 acv or a 220acv? at -10c a 1000w will not keep up unless its a really small tub how big is the tub??? It is 230VAc/50Hz and the heater is on. The dealer her in Norway told me that it will be no problem in the winter but I am a little skeptical. It is Mallorca mod. 1360liters of water. I belived hot spring was made for winter use.
