Criteria Used for Evaluation

Effectiveness

What good is a pool heater if the water isn't warm?

Swimming is a very good form of exercise. Some people prefer to swim because it is refreshing but you lose the same amount of calories just by doing a few laps.

During the cold season, taking a dip gets a little too challenging because the water can get really cold. And a cold dip on a cold weather doesn’t sound inviting at all. But what if, the water is warm? Now, that is a different story! It becomes more relaxing, imagine that! A warm pool waiting for you at the end of the day! It will not just help you relax, it will also help soothe your body aches and pain and you will feel the stress just leaving your body and even help you get a good night’s sleep!

Accessories

Another thing you have to consider when buying a swmming pool heater are the additional accessories.

Putting aside the motor eficiency, heating capacity and voltage, that are all considered as basic features, but there are also some additional accessories that can help you make your choice. For instance, not all heaters are suitable for every pool. Also, some of the products on the list have digital control systems that allow you to change the temperature to your liking.

Capacity

The capacity of the pool will be another important factor to consider because some units are suitable for small to medium pools and some are for larger pools.

While you can make a rough estimate by way of a rough calculation, we suggest you consult with a professional to give you a sound recommendation.

When planning on installing a swimming pool usually these types of recommendation are already included but for some who already have a swimming pool and are contemplating on buying a new one or replace an old water heater, then we still think it’s best to consult a professional. For instance, if you are thinking of switching to solar panels you have to know how many panels would be sufficient for certain pool sizes. Because buying solar panels are in sets or pairs and you can’t just add one or two if you feel it is convenient.
