Tips and Tricks: Keeping Your Hot Tube Warm
1) Make sure the insulation behind the hot tub doors is securely closed and add tape between each sheet of thermofoil to hold them together;
2) Turn off the air valves, otherwise cold air will continuously flow into the water when you are not using your hot tub;
3) A hot tub plugged into a 240 volt outlet increases the capacity of the water heater from 1 kWh to 4 kWh on 40 amps. Please note that an electrician is required;
4) The hot tub usually loses 3 to 5 degrees after about 30 minutes;
5) Depending on the year of manufacture, block the 3"" drain holes located under the hot tub. They are accessible by opening the hot tub doors (careful, don't block 1"" holes or less);
6) Finally, double the insulation by adding Roxul Rockwool, available at all good hardware stores, on three sides. It is important not to add it to the side of the pump and heater.
