Factors to Consider When Buying the Best Pool Heat Pump
There are several factors to consider if you want to buy the best pool heat pump. Make sure to read each feature carefully to make an informed purchasing decision.
Pump Size
One of the first factors to consider before buying a heat pump is its size.
Think about your pool dimensions. Take note that different-sized pools have distinct heating requirements. Larger pools obviously need more heating power compared to small spas.
Besides the pool size, you also have to factor in the humidity levels, average temperature rise, and wind exposure. Doing so can help you determine the size of the heat pump you need.
If you want to learn about the temperature rise, take the average pool temperature during the winter. Then, deduct this amount from your desired water temperature.
You can also visit some pool heater manufacturers. Check if they have a calculator to help match your pool to the right heat pump size.
BTU Output
The BTU output is another important consideration when shopping for a pool heat pump.
BTU stands for British thermal units. It refers to the heat amount needed to increase the temperature of a pound of water by 1°F.
You have to do the right calculations if you want to know the right BTU output for your pool. Use the following formula:
(Surface Area) x (Temperature Increase) x 12 = (Minimum BTU Needed)
For instance, you have a 15 x 30 feet pool with an overall surface area of 450. You know that it has a current temperature of 65°F, but you want to raise it to 80°F. That means an increase of 15°F.
Multiply 450 (pool surface area) by 15 (desired temperature increase). Then, multiply the result by 12. You will need a pump with at least 81,000 BTU output for effective heating.
Type
There are three types of pool heaters—electric, gas, and solar. Each one offers pros and cons, so it is up to you to choose which one suits your needs.
However, this list of the best pool heat pumps only includes electric models.
Electric pool pumps cost less to operate. They do not use propane gas to heat the pool pump, which can cost a lot, especially in cold weather. Electric heaters are also more energy-efficient than gas heaters.
Solar heat pumps are also a great alternative to gas models. However, they have a high upfront price. They might also have limited use because they depend on the sun to heat water.
Durability
Choose a durable pool heat pump if you want it to last for several years.
Consider the materials used. Look for one with corrosion-resistant properties. You can expect them to withstand pool chemicals, saltwater, and other harsh outdoor elements.
You might also want to buy one with a casing. This can protect the heat pump from water damage, temperature changes, and impact.
Efficiency
Consider the energy efficiency of a pool heat pump if you want to use less energy to operate it.
Look for the coefficient of performance (COP). It usually ranges from 3.0 to 7.0. The higher the COP number, the more energy efficient the heater is. Hence, choose a pump with a COP closer to 7.0 if you want to produce more heat at a lower cost.
Ease of Installation
You might also want to buy a heat pool pump that is easy to install.
Check the fitting size required and choose one with convenient access. It is also important to meet the power requirements. So if you do not know how electrical connections work, it might be best to employ professional help.
Improper installation can lead to reduced efficiency. It can also damage the heat pool pump and void the warranty.
Price
Electric pool heaters vary in price depending on their size, ease of installation, and overall capability. On average, these pool pump heaters can cost you between $1000 and $3000. However, more powerful models can easily set you back more than $3000. Not everyone has this kind of budget, so it is understandable if you set your eyes on more affordable units.
Besides the actual upfront cost, you also want to consider the installation cost. Of course, you can always go the DIY route. However, it is recommended to hire a professional if you do not have electrical service around your pool.
Warranty
Do not forget to check if the pool heat pump has a warranty. Buy one with a longer coverage as it indicates the quality of the unit. A longer coverage also means that the manufacturer is confident that its products can last you for several years.
It is also best to check if customer service support is reliable or not. Some manufacturers might offer a lifetime limited warranty, but they can be difficult to contact.
Frequently Asked Questions
How do pool heat pumps work?
A pool heat pump has a built-in fan that can pull in outside air. Then, it directs the air over the evaporator coil to convert it to heat energy. Finally, the hot gas in the coil passes through the compressor and increases the water temperature. It ultimately heats your pool and extends the swim season.
Pool heat pumps use electricity to power their components. But since they take advantage of natural heat, they use lower energy than traditional electric or gas heaters.
How fast does a heat pump heat a pool?
The amount of time it takes for a heater to heat your pool depends on several factors. These include the pool size, the BTU output, your desired temperature, and the current outdoor temperature.
But to give you a general idea, it takes at least eight to 14 hours to heat an average-sized pool (10,000 gallons of capacity).
How warm can a heat pump get in a pool?
There is no one answer because it also varies depending on the capability of the heat pump.
On average, it can reach water temperatures between 85°F and 89°F. Some powerful heaters can even increase the temperature up to 90°F and above.
However, electric pool heaters only work efficiently if the outside temperature stays in the 45°F to 50°F range. Once the weather gets colder, these devices will not be able to warm the water as much.
How to install a pool heat pump?
You can install a pool heat pump on your own if you want to cut down costs. Below is an overview of the step-by-step installation process.
The first thing you must do is choose a suitable heater location. Select an area near a power outlet and the pool filter. You also have to ensure that airflow is not restricted. Consult your product manual for the proper clearance.
Then, connect the heat pump to the plumbing pipes. Use the right connections and fittings to ensure proper water flow. Some units already include these for your convenience. But if not, you can purchase PVC pipes—just make sure they are the right size.
Once everything is connected, plug the pump into the power outlet. Allow it to run for a few minutes. Finally, make sure that the water properly enters the heater and inspect for any leaks.
How to maintain a pool heat pump?
A pool heat pump can easily last you for several years, as long as you properly maintain it.
The most basic maintenance is to ensure sufficient airflow around the heat pump. Remove any debris that might block the air movement. You must also ensure that there are no insects or rodents nesting inside the unit.
Furthermore, it is essential to install the pump in a flood-free area. Keep the unit away from water because it can damage the internal components.
Finally, turn off the heater if you will not be using it more than once a week. Doing so can help reduce electricity costs.
Are pool heat pumps worth it?
Pool heat pumps do not come cheap, so you might be wondering if they are worth the purchase or not.
However, these electric heaters have lower operating costs than gas heaters, especially if you live in a relatively warm climate. They do not require propane gas to generate heat. At the same time, they provide more economical heating while using lower energy.
Pool heat pumps also require little to no maintenance. They can last you for several years with proper care.
Overall, they might be worth buying, especially if you want to extend the swim season.
