Is a spa pool heat pump worth it? - Spa World NZ

Want to lower your spa running costs? A heat pump could be a smart investment, helping you maintain a warm, comfortable spa while using significantly less energy. But how much can it really save? And is it the right choice for you?

With competitive price and timely delivery, Nancent sincerely hope to be your supplier and partner.

In this article, we’ll break down how spa heat pumps work, their costs, efficiency, and whether they’re worth it in the long run.

What is a spa heat pump?

A spa pool heat pump works like a household heat pump, but instead of heating or cooling air, it regulates the temperature of your spa or swim spa water.

Unlike traditional electric or gas heaters, heat pumps use ambient air to generate heat, making them a more energy-efficient option. Some models can also cool the water, which is perfect for hot summer days.

A heat pump is an external unit that sits outside the spa and connects via pipes and fittings to the spa’s plumbing system.

It is important to note that heat pumps only work with heat pump-compatible spas, such as those sold by Spa World.

How does a spa heat pump work?

Heat pumps function like reverse-cycle air conditioners—they extract warmth from the surrounding air, amplify it, and transfer it to your spa water through a heat exchanger.

Most spa heat pumps can generate up to five times more heat energy than the electricity they consume, making them a cost-effective alternative to standard electric or gas heaters.

They take about the same amount of time to heat the water as built-in electric elements but do so far more efficiently.

Are spa heat pumps energy efficient?

Yes, heat pumps are considered the most energy-efficient heating option for spas and swim spas.

Comparison with other heating methods:

  • Standard electric spa heaters convert 1 kilowatt of electricity into 1 kilowatt of heat (100% efficiency).
  • A heat pump can generate up to 5 kilowatts of heat per kilowatt of electricity used—making it up to 75% more efficient than electric heating.
  • Gas heaters, while effective, tend to be less efficient and come with higher running costs.

Heat pumps are by far the most energy efficient and cost-effective way to heat your spa.

Using refrigeration technology, they heat your spa water much faster and use less energy than the spa’s inbuilt electric heaters.

Potential Energy Savings

While individual savings vary based on spa size, climate, and usage habits, heat pumps can significantly reduce electricity costs—often paying for themselves within 2 to 3 years for a standard spa and as little as 12 months for a swim spa.

Example: Heat Pump vs. Electric Heater Energy Use

For every 1 kilowatt of electricity used:

  • A standard electric spa heater produces 1 kilowatt of heat.
  • A heat pump produces up to 5.5 kilowatts of heat—giving you up to 4.5 kilowatts for free.

This efficiency can translate to hundreds or even thousands of dollars in savings over the lifespan of your spa.

Over a short amount of time, the electricity savings repay the investment, resulting in a $0 net cost. The return on investment (ROI) can be as short as 12 months for a swim spa and 2 to 3 years for a standard spa.

How much does a spa heat pump cost?

The price of a spa heat pump varies depending on brand, size, and efficiency. Generally, prices range between $3,400 and $5,200.

Example: SpaNet® Heat Pump Pricing

As an example, we’ve compared four models of SpaNet® heat pumps, one of the world’s most popular heat pump brands.

SpaNet® heat pump prices (RRP at the time of writing—check with the retailer for the latest prices):

  • SpaNet® SV Series Heat Pump 5.5kW – RRP $3,322.00
  • SpaNet® PowerSmart Generic Spa Heat Pump 8.3kW – RRP $4,385.25
  • SpaNet® SV Series Spa Heat Pump 12kW – RRP $5,173.44

Larger units with higher kilowatt ratings typically cost more but also offer faster heating times and greater energy savings.

Should You Get a Heat Pump for Your Spa?

A spa heat pump makes sense if:

  • You own a swim spa or a 5+ seater spa and want to reduce heating costs.
  • You frequently use your spa, especially in colder months.
  • You want the option to cool the water in summer.

A heat pump may not be necessary if:

  • Your spa is small (4-seater or less) and doesn’t use much power.
  • Your spa is a budget model, where the heat pump’s cost might be disproportionate to the spa’s value.
  • You only use your spa occasionally and don’t mind higher short-term electricity costs.

Important: If a Purezone™ filter is included in your spa, it should not be used with a heat pump, as it may cause a water flow error. We recommend using pleated filters instead.

Comparing Heat Pumps and Gas Heaters

Heat pumps and gas heaters both have their pros and cons. Gas heaters heat water quickly but are expensive to run. Heat pumps take longer to heat water but are much cheaper to operate. For those who use their pool frequently, heat pumps offer a more cost-effective solution in the long run.

Environmental Benefits of Heat Pumps

Heat pumps are environmentally friendly. They use renewable energy from the air and emit fewer greenhouse gasses compared to gas heaters. By choosing a heat pump, you contribute to a cleaner environment and reduce your carbon footprint.

Maintenance

Maintaining a pool heat pump is straightforward. Regularly clean the filter, check for debris, and schedule annual professional inspections. Compared to gas heaters, heat pumps require less frequent maintenance and have a longer lifespan.

How Heat Pumps Work Year-Round

Heat pumps can operate efficiently in various weather conditions. They extract heat from the air, even in cooler temperatures. This makes them ideal for extending your swimming season, allowing you to enjoy warm water year-round.

Noise Levels

One concern with pool heat pumps is noise. However, modern heat pumps are designed to operate quietly. Noise levels are typically lower than those of gas heaters, ensuring a peaceful pool environment.

Installation Process Simplified

Installing a pool heat pump is relatively simple. Most installations can be completed in a day by a professional. It involves connecting the heat pump to the pool's filtration system and setting up electrical wiring. For a detailed installation guide, visit this resource.
