Spa Heating Types

---

Electric Elements are by far the most common way of heating a spa. They are typically included in most Portable Spas & Swimspas. They are the cheapest to buy, slowest, and most expensive method of heating a spa.

Brands like: Balboa, Davey, SpaQuip, Gecko, Aeware, Hydroquip, Pentair.

Typical outputs are 1.5kWh to 6kWh

Heat Pumps are becoming a very popular method of heating spas and swimspas. They are 3-7 times more efficient that an Electric Element.  They have higher up-front costs, but often pay for themselves in 1-3 years, depending on outlay.

Common Brands are: Sensa-Heat, Madimack, EvoHeat, SpaNet, Astralpool.

Typical outputs are 5kWh to 55kWh

Gas heating is a tried & proven FAST way of heating a spa. If you are an occasional user, this may be the best way to heat your spa. They are the Kings of Speed. Check out their outputs compared to other methods.

Brands are: Astralpool, Hurlcon, Raypak, Pentair, Waterco, Dega

Typical outputs are 15kWh to 110kWh

Solar is a method not recommended for typical spas, as it reequires a fair amount of water to be pulled from a spa. Some swimspas have it, but is very weather dependant and rarely reaches the temperatures required for spa temperatures.

Wood-fired spa heating is a pretty uncommon in Australia. Regulations regarding their use are unclear, and temperature control can be very difficult.

Brands are usually unknown and of Chinese-origin.
