Things to consider when selecting heater for above ground pools:

If you have an above ground pool, then you are probably looking for ways to make it more appealing and enjoyable. One of the best ways to do this is by installing an above ground pool heater. This device will keep water warm even in winter, allowing you to enjoy swimming all year long. However, there are many different types of heaters available on the market and choosing one can be tricky. Here are a few things to consider when purchasing one:

1. Life span

One of the most important things to consider when choosing an above ground pool heater is the life span. A longer-lasting heater will save you money in the long run, as well as increase your comfort level and enjoyment of your pool.

Most manufacturers offer at least a three year warranty for their products, with some going as high as five years or beyond. This should give you peace of mind that if anything does go wrong with your heater within this time period (and it probably won’t), then it will be covered under warranty. If something breaks outside of normal wear and tear, such as internal damage caused by poor maintenance practices or misuse (such as leaving chemicals in the water too long), then replacing parts should be within reach even without any kind of extended warranty plan.

2. Eco-friendly

When you’re searching for the right above ground pool heater, it’s important to consider its impact on the environment. There are many different types of pool heaters to choose from, but some can be more environmentally friendly than others. For example:

  • Solar: These rely on the sun’s energy to produce heat. While they’re not as efficient as other types of heaters, they have an established green reputation and tend to be less expensive (or free).
  • Heat pump: This type uses electricity instead of gas or propane; so while it’s not completely renewable energy, it still has lower emissions than traditional models.
  • Natural gas: This heats pools with natural gas instead of electricity; however it still produces greenhouse gases like CO2 and methane, just not directly in your backyard!
  • Propane: If you want something that burns cleanly and doesn’t require additional maintenance beyond refilling your tank every now and again then this might be a good option for you (but don’t forget about other costs such as installation fees).

3. Price

The price of a pool heater can range from $500 to $2,000. The size and type of the heater will affect its price. The larger the pool, the more gallons of water it holds and thus a larger heater is needed to heat that amount of water.

The size and type of your pool’s particular pool pump also factors into how much you will have to spend on a heater. If you already have an existing pump for your swimming pool, check with local hardware stores or online retailers for recommendations on what types work best with that specific model. Your local installer should be able to offer some guidance as well when selecting an appropriate pump for your above ground swimming pool system as well as help determine if there are any additional costs associated with purchasing one at all (i.e., installation fees).

4. Easy to use

The best aboveground pool heaters are easy to use. You should be able to install and operate them with ease, as well as maintain them when necessary. They should also be easy to repair if something breaks down, such as a heating element or thermostat. When you are ready to upgrade your current heater or purchase a new one, consider how easy it will be for you and your family members to use the product once it is installed in your backyard.

The best aboveground pool heaters will also take up minimal space when they are stored away during the off season. If this is an important factor for you, research the available models so that finding one that suits these needs becomes much easier than choosing blindly without knowing what else is out there on market today!

5. Heater Capacity

You should also consider how many gallons of water your pool holds when choosing a heater. If your pool is small and holds only 100 gallons, then it does not matter as much if it has a large capacity or not. But if your pool holds 500 gallons or more then you should get a higher capacity unit because it will be cheaper in the long run because it will take longer for it to break down from overuse than if it were a lower capacity unit.

6. Size of pool

The size of your pool is an important factor when deciding on a heater. Smaller pools (up to 20 feet) can get away with a smaller and less expensive heater, while larger pools need more power to heat the water. You should also consider the depth of your pool. The deeper your pool is, the more heat it will require to keep it warm enough for swimming in the winter months.

7. Maintenance

The best above ground pool heaters are easy to maintain and repair. All you have to do is drain the water from the pool heater and clean it out. If you have a gas heater, then you will have to check the propane tank for leaks and make sure that it is full. You also need to make sure that the gas line is not clogged or blocked.

If you have an electric heater, then you should clean out any leaves or debris that might be blocking the filter screens in the filter pump housing. You can also clean off any dirt or dust from around your pool heater if necessary.

8. Replacement Parts

Most above ground pool heaters do not require replacement parts very often, but when they do need them, it can be very expensive! This is why it’s important to take care of your pool heater so that it lasts as long as possible. In general, most above ground pool heaters will last anywhere from two years to five years with proper maintenance and care.

9. Warranty

A good warranty should cover parts, labor and service. A more expensive unit will probably have better quality parts, but if you’re going for a budget option the warranty might be your best bet. The warranty should be at least 5 years for an above ground pool heater. Some companies offer warranties as long as 10 years.

The length of time that the heater is covered by this warranty is also important. The longer your heater’s warranty period is, the more confident you can feel about purchasing it without worrying about paying extra down the road when something breaks or needs repair or replacement because it won’t cost you anything to do so.

Some tips:

If you want to enjoy swimming in your above ground pool all year long, then you need to get the best above ground pool heater.

Summer is just around the corner and soon it will be time to pack up the winter sweaters and break out the bathing suits. You will want a reliable way of heating your pool so that it’s ready for those hot summer days when everyone wants a dip in their favorite body of water. A good quality above-ground pool heater can provide you with warm water at any time of year, allowing you more opportunities for fun with family and friends!

There are many different options available when choosing an on-demand heating system for an above ground swimming pool, but one thing remains true: You should always do your research before purchasing anything online because there are many websites that may not have all the information they need about different products that could save buyers money on their next purchase (or cost them dearly).
