Pool Heat Pump FAQs

Take a look at our FAQs for answers to some of your most common questions about pool heat pumps.

Why do you recommend heat pumps based on the surface area of the pool, rather than the total water volume?

The size of heat pump we recommend is intended to maintain your pool at your preferred temperature. There are many factors that we consider when recommending a heat pump, however one of the main ones is the surface area of the pool. This is because this is the largest exposed area of water, where the most heat loss occurs.

Should I use a heat retention cover over my pool?

Heat retention or thermal pool covers are a great way of reducing the running costs of a heated pool. They reduce the heat loss from the pool surface, which means that a smaller heat pump can be used to maintain a similar temperature. If you are unsure, give us a call to discuss.

How long can I expect my heat pump to last?

This depends on the running conditions of the heat pump, and other factors including whether it receives regular maintenance. However, typical life expectancy of our heat pumps is 15-20+ years.

What do you mean by ‘extended season’?

The extended season is the period between mid-October and mid-April. It is the length of the season during which you are able to enjoy your pool in comfort if you have installed a heat pump to regulate temperature.

Why have you recommended a different size heat pump to other brands?

There are many different reasons why we may recommend a different size heat pump than another brand. We have years of experience in sizing heat pumps for the specific temperature and climactic conditions that Australia experiences. Our business specialises in heat pumps, and so we have a deep understanding of how they work and their efficiency in different situations, which other businesses which do not have our specialist knowledge may not have.

We are able to custom build, and we have a very wide range of standard heat pumps with much more variety than most other brands. This gives us more flexibility in sizing a unit for your specific requirements, which other brands may not have.

The components that we use to build our heat pumps are high quality and designed by engineers with over 30 years of experience in the field. The compressors in our heat pumps are up to twice as efficient as some other brands, which is another reason we may recommend a different size of heat pump than others would.

Does winter or cooler climate lower heat pump efficiency?

It does. Because heat pumps draw their heat from the air around them, the efficiency of the unit is generally reduced when the air temperature is cooler, as there is less ambient heat available to draw from. However, we have taken this into consideration in the design of our heat pumps, as well as in the sizing that we recommend. Our heat pumps are designed to maximise efficiency, making them very effective in cooler conditions.

What temperatures will your heat pumps operate in?

We have designed our heat pumps to operate effectively in air temperatures down to -10 degrees Celsius.

Do these heat pumps have de-ice control?

Yes, all of our heat pumps have an advanced de-ice system as a standard feature. This helps to melt ice on the coils quickly so that the heat pump can continue to operate normally, and is essential for effective operation in situations where the ambient temperature is low.

Why are your heat pumps bigger than other brands?

In order to maximise efficiency and improve the output of our heat pumps, we have designed them specifically to get the best out of every situation. To do this, we produce our heat pumps with a much larger evaporator coil than most other brands, which means that the maximum amount of ambient heat is extracted from the surrounding air, with a higher level of performance. In order to house the larger coil and minimise noise levels from the fan, the housing of the unit is built bigger.

What does ‘wet bulb air temperature’ mean?

Different to the ambient air temperature, the wet bulb air temperature is the temperature it feels like when you have wet skin. This can sometimes feel a lot cooler than what the actual temperature is, because the low humidity of the air is so different to the moisture on your skin. Refrigeration technology operates on wet bulb air temperature. Heat pumps generally perform better in high humidity, and often produce condensation.

Should my pool be insulated?

Insulating your pool will ensure that the water temperature can be maintained at a comfortable level, without losing heat through the walls or from the water surface. Any form of pool heating, whether by a heat pump or other methods, will be more efficient if your pool is insulated. Speak to your pool builder about the best way to insulate your pool before it is built.
