How Are Hot Tubs Heated?

A hot tub without heat is like an ice cream cone without ice cream. An essential component is missing. Hot tubs, by definition, require heated, massaging water. So, how are hot tubs heated? In this article, we’ll go over the various types of hot tub heating and what you can do to make them more efficient.

How Is Hot Tub Water Heated?

Most hot tubs use electric water heaters to raise the water temperature. Some traditionalists might prefer a wood-fired hot tub or one that relies on a hot water spring, but they require extra effort or being lucky enough to have easy access to a natural phenomenon. Some hot tubs run on solar power although it may need to be converted into electricity to run the water pump and heater. Other solar-powered hot tubs rely solely upon the sun to heat the water, but still require electricity to pump the water. No matter the type of system is used to heat the water, there are always ways to make that heating more efficient.

Maintaining A Consistent Water Temperature

If you’re looking to conserve power and/or reduce your energy bills it might seem to make sense to turn off your water heater and pump after you’re finished using the hot tub. And while this might be the case with a wood-fired hot tub or in a high-temperature climate, hot tubs that run off electricity are often more efficient when a consistent water temperature is maintained. This is especially true in freezing weather conditions. Turning off your hot tub during sub-zero weather could lead to irreparable damage to your plumbing. If you use your electricity-powered hot tub consistently and aren’t experiencing a major heatwave, leaving your hot tub running when it isn’t being used will ultimately reduce your overall power consumption.

The Importance of Insulation

Hot tubs can be bought from the showroom with varying degrees of insulation. Those who live in colder climates and expect to use their hot tub throughout the winter will benefit by investing in as much insulation as possible. A poorly insulated hot tub will quickly lose its heat through the plumbing, shell, and cabinet walls. Make sure to match your hot tub insulation with the climate that you live in.

The Importance of a Hot Tub Cover

Hot tub covers are not only important for keeping debris out of the water when it isn’t being used, they’re also important for keeping the heat in the water when it isn’t being used. Most of the heat that escapes from the hot tub occurs through the water’s surface. And when you consider the hot tub will be sitting idle throughout the night and for most of the day, it truly pays off to keep it covered when it’s not in use. Those who live in colder climates should invest in a highly insulated cover as well as a floating, insulated water blanket.

The Importance of Protection from The Wind

Wind can play a major role in both water evaporation and the cooling of the hot tub water. Hot tubs that are exposed to strong winds will be more difficult and expensive to keep heated. When choosing a location for your hot tub, this should be kept in mind. If it’s impossible to prevent the hot tub from being exposed, investing in some wind barriers can reduce your reliance on your water heater. These could be in the form of trees, shrubs, bushes, or specialized windscreens.
