Whilst many people even in cold climates choose to run their hot tubs all year round, the vast majority of people will only run their hot tub in the Summer months and simply empty the water out of it at the end of the season, put the cover back on and then simply just hope for the best over the winter months.
However this can prove to be a very expensive mistake indeed. It is a bit like taking a car off the road for winter, you need to do the correct work on it to make sure that it fires up first time next summer.
This is because just like a car a spa tub can be badly damaged by frost over winter. If your car radiator freezes in winter due to lack of antifreeze then it will crack and leak due to the cold weather, so why expect your hot tub to be any different?
When it comes to making sure your hot tub is ready for winter you will need to have a wintering routine, and this means ensuring that all water is drained out of the system. If even the smallest amount of water is left in the system it could freeze in winter and break a pipe or worse still it could break the water pump resulting in a nasty bill next summer.
Prior to shutting it down you will need to flush the system with a spa flush solution. You should then turn on the air blower to remove any remaining water from the vents, just note that the air heater should be turned off prior to doing this, if not it will overheat.
When all of the above is done, turn the power going to the tub off, then remove all of the systems filters (and change them prior to next season) and finally loosen off all of the hot tubs adjustable fittings.
Vacuum any debris out of the spa tub and then wipe the whole of the inside of the tub with a non-foaming cleaner.
When everything is perfectly dry ensure all access panels are secure and place the cover back on the hot tub.
When it comes to getting it ready for Summer then simply repeat the above process in reverse.
Time spent wintering your investment will pay long term dividends and avoid costly frost damage over winter, as frost damage to it can cost hundreds to replace. So time spent preparing your tub for winter is time well spent, and could save you money in the long term.
