Introduction to Pool Heat Pump
Pool Heat Pumps are the most efficient pool heaters in the market. These machines do not generate any heat by themselves, but instead, they use electricity to capture heat and then retain and move it from one point of the pool to another. This basically means that unlike other pool heaters that need a continuous power supply, pool heat pumps will only capture a small amount of heat and use it to keep your pool warm for extended periods. As a result, pool heat pumps cost a lot less in running costs than other pool heating options. This makes them a favorite to a lot of pool owners who are willing to spend relatively more on getting and installing a pool heater that’s long lasting with minimal running costs. If maintained properly, pool heat pumps will also last a lot longer than gas pool heaters and other options.
What makes pool heat pumps an excellent choice is their efficiency but how exactly do they achieve this? To understand this, we have to look at how these machines work. As we already pointed out, pool heat pumps utilize electricity to capture heat which they then transmit to your pool water. These heaters pump your pool’s water through the filtration system and the heat pump heater. This heater comes fixed with a fan that draws in air from outside the pool and passes it above the evaporator coil.
The evaporator coil contains liquid refrigerant which absorbs heat from the air to become a hot gas. The gas is then passed through the compressor where it is heated even further before proceeding to the condenser. It is at this point that the heat from the warm gas is transferred to the cold pool water moving through the heater. The water gets warmed up and then its pushed back to the pool as cooler water circulates through. On the other hand, the hot gas in the condenser coil gets converted into liquid form, and it’s returned to the evaporator where the whole process starts again.
Weirdly enough, the cooler the outside air, the more efficient these heaters are. Pool heat pumps work best when the surrounding temperatures are between 45ºF and 50ºF. Most pool heat pumps also use scroll compressors to improve efficiency even further.
Buying the Best Pool Heat Pump
There are so many pool heat pumps, and they are all uniquely designed to be used with certain types of pools. Therefore, to get the best pump that will work for your pool, you need to consider various crucial factors which include:
The best thing about having quite a lot of pool heat pumps to choose from is the variety of options that you get. Different pool heat pumps have different daily, monthly and even lifetime operating costs. When purchasing these pumps, you get an opportunity to calculate their operating costs and choose one that suits you best.
Take note that most pool heat pumps have quite a steep initial cost. Purchasing and installing these pumps can be quite high, but the good thing is that they compensate on it with their high efficiency. Spending a little bit more in acquiring and setting up a heater that will save you hundreds of dollars in operating costs is a lot better than a cheap heater that’s expensive to run, don’t you think?
In calculating the operating cost, you should also include the initial cost, maintenance, and repair to determine the overall cost of owning the pool heat pump you are eyeing.
A pool heat pump’s compressor is where the refrigerant is condensed into a hot gas. Buyers get an option between two types of compressors; reciprocating and scroll compressors.
Reciprocating compressors used to be so popular because they were affordable and very compact. Over time, however, issues with their efficiency were raised and this is when scroll compressors came in. Scroll compressors use metal scrolls in compressing refrigerant. Their overall designing is also entirely made to boost energy-efficiency even further, and the best part is that they are durable and cost much less to operate. Scroll compressors are also made with fewer moving parts, and this has significantly reduced the need for frequent maintenance and cases of malfunctions.
- Heat Exchanger
The heat exchanger is the medium through which heat is transferred from the condenser to the swimming pool’s water. Standard heat pumps are made of either cupro nickel or copper heat exchangers. The two types of exchanges are both efficient and affordable, but manufacturers have in recent years, started using titanium exchangers which are corrosion resistant and more durable. Unfortunately, titanium exchanger tubing is usually very expensive, but it provides the best performance to everyone who can afford it.
Pool heat pumps are rated according to their horsepower and Btu output. The ideal pump size that will work for your specific swimming pool depends on quite a lot of factors. These include your swimming pool’s surface area, wind exposure, cool nigh temperatures, humidity levels, the average air temperature, and the pool’s temperature. Sizing a pool heat pump as you can see can be quite complicated. The good news is that you can get a professional to do the hard task and give you an accurate and detailed report that will help you get the right size of the heat pump.
