What Is The Best Hot Tub For Cold Climates

What is a hot tub without heat? It wouldn’t be much more than a large bucket of water. Along with massaging water jets, heated water is one of the main characteristics that define the hot tub experience. It becomes even more important when the weather outside is cold. Soaking in a hot tub in cold weather wouldn’t be anywhere near as popular as it is if it wasn’t possible to keep the water temperatures at a reasonable level. If you’re wondering which are the best hot tubs for cold climates, we’ve put together this list of important characteristics.


When it comes to insulation, not all hot tubs are built the same. If you live in an area with colder climates, buying a hot tub that is properly insulated will ensure that you can maintain an ideal water temperature without drastically increasing your energy bills.

Properly insulated hot tubs should prevent the escape of heat wherever possible. It should also make use of waste heat generated by the water pump and heater by directing it back towards the water.

The piping that the water runs through is a primary area of heat loss and should be well insulated. Insulation that makes the best use of air pockets is particularly effective around plumbing and should be combined with a traditional insulative covering.

Because the floor of most hot tubs is often in direct contact with a concrete pad or other heat-conducting bases, it should also be properly shielded to reduce heat escape.

The walls of the hot tub cabinet should also be insulated to retain heat radiated from the mechanical components and the hot tubs shell. The cabinet is the last defense against the escape of heat from the inner workings of the hot tub.


Hot tub covers are often erroneously described as accessories. a well-insulated hot tub cover is imperative – especially when it comes to operating a hot tub in a cold climate,

Hot tub covers come in a variety of materials, thicknesses, and other features like assisted lifters. When comparing like-for-like materials it only stands to reason that a thicker cover will provide the best insulative ability to keep to the cold.

When it comes to heat escaping a covered hot tub, it’s typically around the areas where the cover folds that are most problematic. Look for covers with insulated baffles along the folding lines to reduce the amount of heat that escapes.

Employing a floating thermal blanket in conjunction with your hot tubs cover is another way to retain heat when the hot tub isn’t being used. The thermal blanket can also reduce wear and tear on your hot tub cover by protecting the underside from humidity caused by water evaporation.

Adjustable Vents

Adjustable vents allow you to lock heat into the hot tub cabinet space during cold weather while allowing it to escape during warmer weather. If you live in an area that experiences large temperature fluctuations, you should check the cabinet design for any areas that allow exposure to the environment. Being able to control any such ventilation will reduce dependence on your hot tub water heater and lower your energy bills in cold weather.

Energy Efficiency

If you’re running your hot tub in the winter, the amount of energy you’re using to heat your water will necessarily increase. To prevent unreasonably expensive power bills, investing in a hot tub with an energy-efficient filtration system and water pump will be worth the extra upfront cost. This includes looking for systems that can filter the entire volume of the hot tub in as short an amount of time as possible and water pumps that provide a high rate of flow with low energy requirements.
