Differences Between Inground And Above Ground Pool Heaters

Inground pools, on the other hand, will take a maximum of 5-8 weeks once the installation process starts. Some pool builders may complete the pool earlier, but due to some common factors such as bad weather may slow down the process.

Pool Cost

Aboveground pools may range from around $900-$ 3000 when dealing with online DIY pool packages to around $4,000-$8,000 with local pool dealers. However, the price will also depend on the size of the pool, ad the quality of components. With Inground pools, the price may cost around $5000-$8000 for online DIY pool kits. For local installation, the inground pool may cost around $30,000-$50,000. Like all other pools, the price will depend on size, pool type, and optional features.


Space may not be a determining factor in deciding whether to build the aboveground pool or inground pool, but it will determine the shape or size of the pool. However aboveground pools may be surrounded with wood deck depending on the terrain while the inground pool may take any shape and can be small or as large as you want.


Many homes have different slopping surfaces. Some are having slope downs and slope ups. Terrain may affect the choice of an aboveground and inground pool. However, the inground pool may work well in sloping terrain compared to the aboveground pool, but it will be too costly.

Soil and Water

It is always tough to dig inground pools in places with big igneous rocks; hence aboveground pool may be considered as an alternative. Constructing an inground pool in places with marine clay and sandy soil can also be stressful. De-watering will also be required in places with a high water table when constructing an inground pool; hence one may opt for aboveground pools in such areas.

Different Types of Inground Pool Heaters

You may want to start with this article so you can narrow down some options when looking at a pool heater. Let’s go over to What Size Heater for My Pool? and see what we can calculate to narrow the field down some.

Gas Heaters

These are heaters that are run on natural gas and propane. They thus require the use of a propane tank or also a natural gas hookup. The gas heaters can end up being more expensive regarding operation. They will be working great for the pool owners looking towards turning them on when they have visitors. In case the pool has been located at a vacation home, it will only get used periodically. It is easier to keep water at a consistent temperature with the use of a gas heater regardless of the weather’s nature. As a result, gas heaters are tending to work more significant for the spas.

Heat Pumps

Heat pumps are relying on electricity in their operation. Air will be pulled through the pump and will be run through the present compressor. This kind of pool heater is best for pool owners and athletes looking to benefit from the therapy. They will end up maintaining consistent temperature without paying much attention to the weather. They are keeping the water in a warmer state than the other primary swimming pool heaters.

Solar-Based Pool Heaters

Solar based heaters are using the sun’s heat to help them in warming up of the pool. The present pool pump will be running water through the heater located at the roof of a given building or house. Swimming solar pool heaters will be working only during day hours and best in the case of bright and sunny days. They are quite limited regarding how much they will be increasing the water temperature.

What Types of Pool Heaters Do You Need?

The best heaters are solar heaters. The significant benefit of solar heating is the fact that it is free of charge. You will end up heating large volumes of water without any expenses.

The solar water heater has the capacity of providing to even 80% of hot water needs even while in temperate climates. It is thus translating into significant utility bill savings from one month to the other.

Factors to Consider When Choosing the Best In-ground Pool Heater

A pool heater is one of the essential devices you should consider installing in your pool. However, if you are considering upgrading your swimming pool, the following factors should be considered.

Matching your pool size

It would be best if you considered buying a medium-sized heater for your pool. A small pond will not get the work done while an oversized heater will waste energy. Matching your pool’s gallon with the heater’s capacity is very important. A heater with BTU ratings of 100-200 should be used within the pools with a capacity of 2000-10,000 gallons. The surface area of the pool should also be another factor to consider. It is because of the more the surface area, the faster the heat loss.

Maintenance of the pool

Suppose you need the pool heaters to operate efficiently, proper caring need to be done throughout the year. Besides routine cleaning, heat pumps require appropriate fixture at required levels. When you are using solar heaters, its servicing should only be done by a trained solar energy expert. Getting a trusted pool care team will help you maintain and have the necessary repairs when required.

Choosing your power options

Pool heaters will automatically add the utility bills of your monthly expenditure. Considering the operating cost should be a factor when choosing a pool heater. For instance, solar heaters are exclusively running on solar power and will only impact your wallet at purchase. Gas heaters will require a connection with a gas line or decide to have propane tanks (propane is ridiculous in my area). Electric rates can vary dependent on your location and supplier.

All that will not come cheap; hence you will have to dig a little deeper into your pockets. The good news is, you are trying to heat the pool when your house heating and cooling bills are less. Yep, typically the average pool in the USA is heated in spring, and fall.  This is to jump start, and extend use season.

Using a heat pump is more efficient with energy but are always limited at the beginning and end of the swimming season. Electric pool heaters are the most convenient but are also very expensive. Electric heaters are mostly used in indoor pools and spas.

Noise issues.

You will always want your pool area to stay calm, peaceful, and away from unwanted noise. Some heaters have pumps, fans, and motors that produce a lot of noise, thus not favorable for a noise-free neighborhood. Most heaters require the circulation of water to and from the pool, usually provided by the pool pump. Solar heaters do not produce sound at all; hence, they are more efficient by way of cost turned to heat.

Electric is another quiet pool heater, however a heat pump style pool heater has a fan that may kick on like a central air unit turning on. typically the gas powered heater, propane or natural gas have the noise of the exhaust of the combustion.

Placement of the heaters near the pump or farther away from the ear may negate any notice of the noise. This can sometimes be a better compromise than trying to heat with solar because you do not have the area for the panels, and, or there are shaded areas where you can mount them.
