How to Choose the Best Above Ground Pool Heaters?

above ground pool heaters

The most efficient heating solution for above ground pool heaters is the pool heat pump. When compared to conventional heating equipment, a decent pool heat pump can save 65 to 70% of the heating capacity.

Furthermore, because the pool heat pump is a very environmentally friendly device, it is becoming increasingly popular among consumers these years. However, how can you select the best above ground pool heat pump for your swimming pool?

How to select Above Ground Pool Heaters?

Noise

Heat pump noise emissions have almost surpassed cost as the most critical choice consideration. The plots of land are very small, especially in urban areas, and one does not want a noisy heat pump on the property line to ruin a good relationship with the neighbors.

Because the efficiency of middle-class heat pumps is frequently comparable, the price differences are most visible in noise reduction techniques. Heat pumps with ABS housing are often quieter than those with metal housing.

If you’re going to put one near the pool, make sure it’s a silent model. I would suggest the full-inverter pool heat pump with a silent feature in this case.
Modern inverter heat pumps are far quieter than “regular” heat pumps in SILENCE mode, roughly half the volume. These pumps create hardly more noise than a puff of air in regulated mode: only 20 dB!

Efficiency

The coefficient of performance (COP), which is a measure of how much heat a pool heater uses, normally varies from 3.0 to 7.0 and produces an efficiency of roughly 50%  for the ON / OFF type. 

  • ON-OFF:

A constant compressor speed is used in most above ground pool heat pumps. This type of heat pump has a COP of around 4.5-5.0 at 15°C and 5.0-7.0 at 26°C. On the more efficient variants, an Electronically Controlled Expansion Valve (EEV) guarantees that good efficiency is obtained more evenly throughout a larger temperature range.

  • Full- inverter:

Swimming pool heating is reported to be good with full-inverter heat pumps. They have two modes of operation: ECO and SILENCE. They can achieve a COP of up to 16 if they operate at a high level of efficiency. 

These heat pumps operate at a very low noise level. As a result, the INVERBOOST tech heat pump series is excellent for consumers who want a heat pump that is both quiet and efficient. When compared to “regular” heat pumps, inverter heat pumps can save between 30 and 50 percent on running costs.

Active defrosting

Depending on which region you live in, the active defrost function will be your best friend and will allow optimal operation at low temperatures.

  • pool heater defrostIce begins to form on the heat exchanger of the outdoor unit when outside temperatures reach freezing levels.
  • When this happens, your heat pump enters defrost mode to thaw the ice. 
  • This keeps the unit operating at maximum efficiency and prevents damage to the equipment.

The volume of your pool

When choosing a heat pump, the size of the pool and the season are also significant elements to consider. A heater is sized based on the pool’s surface area and the temperature difference between the pool and the ambient air temperature.

The number of gallons in your pool usually determines the size of your pool heat pump. If you don’t know or aren’t sure how many gallons you have, measure your pool and utilize our pool volume calculator tool.

Some heat pump manufacturers list their heaters in BTUs rather than gallons. The bulk of variations ranges from 50,000 to 125, 000 BTUs.

Small pools or aboveground pools of less than 12,000 gallons use 50K BTU heat pumps. It will work in larger pools, but the heating will be sluggish, and the total temperature rise may not be what you desire.

When choosing a heat pump for your swimming pool, take into account the size of the pool and the required temperature change. Other elements that affect a heat pump’s ability to warm pool water include average air temperature, humidity, and wind speeds. Using the following calculation, you can calculate the approximate heat pump BTU requirement based on a temperature increase of 1-1.25 degrees per hour:

(Surface Area) x (Temperature Increase) x 12 = (Minimum BTU Needed)

If you use your heat pump straight through your filtration system, you should increase the kW output somewhat to reduce run times, but here’s an example.

50 – 80m³

Service

It’s the last and crucial part of your consideration when purchasing a pool heat pump. Many individuals are concerned about the quality, price, and amount of technology required, but lifetime servicing is essential.

Heat pumps, if installed appropriately, have the potential to be very dependable. Furthermore, for long service life, a titanium heat exchanger is required. Because they are always outside, they require durable, weatherproof housing. Housings made of ABS plastic or aluminum have shown to be effective in this application.

Calculate the surface area of the pool (pool length x pool width)

The swimming above ground pool heaters must be large enough to meet the surface area and pool size.

Many pool owners mistakenly believe that the number of gallons in the pool is used to determine the size of the above ground pool heaters. Although in fact, some websites use gallons to determine the size. The size of the gallon is very important, but it is not a direct way.

If you have a larger pool,  there will be more space to release heat, and then more water needs to be heated. Instead, if your pool is a small or mini pool like Intex pool, you will need a small pool heater, the mini pool heat pump might be a good choice. Therefore, swimming above ground pool heaters need to be large enough to meet the surface area and pool size. So the surface area is the most important factor. Please multiply the length by the width 

Divide the surface area by 3 (surface area / 3)

After calculating the surface area of the swimming pool, divide it by three. The recommended minimum BTU size for a specific surface area. For example, a pool is 15×30, so the surface area is 15×30. Divide by 3 to get 150. Therefore, for a 15 x 30 pool, the recommended minimum heater size is 150,000 BTU. But be clearly aware that this is only the recommended minimum size. It is possible that you will need a higher BTU.

Because there are many factors that affect heating, such as wind has a great influence on the heat loss of the swimming pool, so whether there is a swimming pool cover requires different heat pump sizes; another example is whether the swimming pool is outdoor or indoor because the floor and walls inside the swimming pool will emit Heat.

The swimming pool heater’s job is to replenish the heat loss on the surface of the swimming pool in time. Most of the heat loss occurs at night. If there is no protective cover, there is no way to make up for the loss. At this time, higher heating above ground pool heaters is required. ALSAVO-Wärmepumpe Wool

Consider all variables for  above ground pool heaters

After you know the minimum BTU recommended for your swimming pool, you must decide whether you need larger above ground pool heaters. Before you make a decision, please consider all variables that may affect the efficiency of the above ground pool heaters, such as whether the pool has a pool cover, wind speed, indoor and outdoor pools, and swimming frequency.

So think twice and double-check before deciding on which above-ground pool heaters to buy. Above ground pool heaters from Alsavo INVERBOOST are the best option.
