Creating the perfectly warm environment in your spa
Ambient water temperatures in Australia fluctuate rapidly throughout the year with the seasons. Heating your spa ensures that you always have a regular temperature, without having to constantly fiddle with heating elements.
An ideal temperature for an outdoor spa is between 36 and 37 degrees Celsius — the same temperature as your body. Maintaining this temperature should be relatively easy for most units in most climates. However, there are several instances when an external heater may be required to assist in regulating the temperature of your spa.
Here are several things to consider when weighing up whether to buy a conventional spa model, or one with an external heating element.
Heating vs non-heating
Most heated spas are now designed to be permanently heated using a relatively small electric heater element. You leave the power on and set your required temperature, and your spa is ready to use at any time. This is an ideal energy efficient solution for most spa owners.
Non-heated spas will require the use of an external heating element. You can read more about these in the section below.
There are several ways to heat a spa, each with their own benefits and drawbacks. When it comes to heating yours, you will want to choose an option that is efficient, fast, and energy-conscious.
- Heat pumps add thermal energy to the body of water via electricity, gases, and conductive metals.
- Electric heaters are another popular element, but may not be as energy efficient as other options.
- Many domestic spas use gas heating as a easily accessible and affordable primary heating system.
- Solar heating is usually relegated for use in pools and larger spas, but can be used for smaller spas as well.
Choosing the right heating element for your spa is an imperative step in creating an efficient heating system. If you aren’t sure of what will work best in your backyard, it’s best to talk to a spa expert, like a member of the team at Oasis Spas.
How long it takes
However, you might not want to keep your spa running around the clock. If this is the case, quick heat-up times might be important to your lifestyle for many reasons, including:
- • If you use your spa infrequently
- • If the spa is at a holiday home
- • If your spa needs to be off around children
- • If you like hosting impromptu parties
If this sounds like you, a gas heater is the best choice. For a holiday home, a heat pump could still be an adequate choice as long as your spa has a wireless module fitted that allows you to control and heat your spa in advance using a phone app.
Size of spa
If the spa is very large, a heat pump is the best option. It can heat a large body of water for up to 70 per cent less than an electric heater and is both cheaper to buy and run than gas.
Climate and location
It’s worth getting an external heater if you are in a very cold climate. Extremely cold outdoor temperatures, like those experienced throughout Melbourne’s winter, may require frequent use of an external heater to remain comfortable.
Design of spa (insulation)
For spas with good insulation, it is not viable to use a heat pump or gas heater. The installation cost of the heater will not be covered by the savings in heating costs.
These heaters also take up space, but they are worth considering if your spa has minimal insulation, or no other features to reduce running costs.
