I have a 2014 HS Glow model and the manual states the following shown below. I was wondering if anyone has bought the equipment compartment insulating kit or if you think I'm ok without it. I live in Northern NY and it can get below 10 degrees here.
PREVENTION OF FREEZING
Your spa has been designed and engineered for year-round use in any climate. In some areas, extremely cold temperatures (below 10°F) combined with strong wind, may cause partial freezing of the jet pump, even though the water inside the spa remains at the selected temperature.
The energy efficiency of the spa may also decrease during these cold periods, as the heater will cycle more frequently. As an additional precaution against partial freezing of some of the components, the equipment compartment can be insulated with an insulating kit (available from your local dealer). This insulating kit will also help to maximize the spa’s energy efficiency. NOTE: When warmer weather returns (approx. 60°-70°F), the insulating kit must be removed to prevent overheating of the jet pump.
