Pool Heater Checklist

Sense Of A Pool Heater
  • A pool heater warms the water to comfortable swimming temperatures.
  • The pool heater can be electric or solar powered.
Types
  • Heat pump (heat by ambient air)
  • Heatexchanger (heat by solar system)
  • Electric pool heater (heat by electricity)
Solar Powered Pool Heaters
  • The water is diverted after the water filter and then passes through the solar panels. In the process, it heats up and flows back into the pool.
  • The connection after the water filter is important to keep the solar system efficient.
  • Advantage: Uses free solar energy, easy to set up, high performance and long life, no maintenance costs, good for the environment.
  • Disadvantage: Works only when the sun is shining, depending on the size of the pool, more than one may be needed.
Electric Heat Pump
  • It is placed next to the pool and connected to the pool with glands. The outside air is attracted by the pump, heated and transferred to the pool.
  • Advantages: hardly any operating costs, particularly efficient and environmentally friendly.
  • Disadvantages: high initial costs, relatively large.
Electric Pool Heater
  • Here, too, the water is diverted, heated by a heating coil inside the pump and released back into the pool.
  • Advantages: easy installation and low initial cost, works regardless of the weather.
  • Disadvantages: high electricity and operating costs, bad for the environment.

FAQ About Pool Heaters

When are babies allowed in the paddling pool?

As soon as a baby can sit, nothing stands in the way of fun splashing around. This is usually the case from 6 months , but can also occur earlier or later, depending on child development. Almost every child has fun in the water.

How often to change the pool filter?

The fitter cartridge must be clean to function well. Therefore, you should check its condition once a week and clean it if necessary. If the dirt is heavy or cannot be removed, the filter cartridge should be changed. As a rule, this is enough every two weeks.

How often to change water pool?

As a rule, the water can be used for one season. However, it is important that the pool is properly maintained, protected and cleaned (appropriate chemicals, filter use and maintenance, tarpaulin, if necessary, manual cleaning with a landing net, …).

Which pool heater does what?

A pool heater warms the pool water to comfortable bathing temperatures. They are made for outdoor use. Thus, even if it is still too cold in terms of temperature, the swimming season in your own pool can be opened earlier. If you need help with the selection, you are welcome to take a look at our guide. There we have listed recommended pool heaters and created a checklist with the most important purchase criteria.

Which pool heater is the best?

This cannot be generalized. It is important to be clear about the respective advantages and disadvantages before buying a pool heater. In addition, it is also relevant for how many years and how often the pool heater is to be used, as this also affects the cost-benefit calculation. The environmental aspect also plays an important factor for most people. So it remains to be weighed individually.

How long does it take to heat up a pool?

The heating time per 1°C water temperature should not exceed four hours. However, this is always dependent on the power of the heater. You should choose it according to the size of the pool . For a heat pump, for example, a power of min. 9 kW is recommended for 30 – 40m³ (for 40 – 60m³ min. 12 kW power, for 50 – 80m³ min. 16 kW power). So pay attention to the manufacturer’s specifications on this.
