Energy saving heat pumps
What is a heat pump?
A heat pump for a hot tub is a device that warms the water by moving heat from the air into the tub instead of generating heat directly. It works a bit like an air conditioner in reverse. A fan pulls in warm air, a refrigerant absorbs that heat, a compressor raises the temperature, and then the heat is transferred to the water.
Key benefits of a heat pump
Eco-friendly
Lower energy use means reduced carbon emissions (especially if paired with renewable electricity).
A greener choice compared to gas or high-wattage electric heaters.
Energy efficiency (lower running costs)
Heat pumps don’t generate heat directly. Instead, they extract heat from the surrounding air and transfer it into the water.
This can make them 3–5 times more efficient than electric resistance heaters.
In practice, you might pay only 20–40% of the energy costs compared to standard electric heating.
Durability
Heat pumps generally have a longer lifespan than standard heaters if maintained well (often 10–15 years).
Cooling option
Our modern hot tub heat pumps can also cool the water, which can be a great feature in hot climates or for hydrotherapy.
Consistent temperature maintenance
Heat pumps are designed to maintain heat efficiently over time, not just for rapid heating.
Ideal for hot tubs that are kept warm continuously, since maintaining temperature costs much less than reheating from cold.
Long-term savings
Though upfront cost is higher, the payback period can be just a few years thanks to lower running costs. This is particularly beneficial if you use your hot tub often.
