How to Identify the Best Electric Pool Heater For You
When deciding which electric pool heater is right for you, there are a number of variables to consider. Take the following factors into account so that your purchase will feel like it’s been worth every penny!
- Pool Size – The size of your pool will significantly influence which type of electric heater you need to purchase because each type of pool has different heating needs. Spas for example require rapid heating of small amounts of water to relatively high temperatures, so a different type of heater is required other than what is typically used for larger swimming pools. Larger pools can take advantage of slower heating to lower temperatures, while maximizing efficiency and saving on energy costs.
- Pool Use Habits – How you use your pool will greatly affect which electric pool heater is best for your needs. If you use your pool daily, you’ll need a heater that is energy efficient and can maintain a consistently even temperature at all times. Conversely, less frequent pool and spa users, ones that use it primarily only on the weekends for example, will need a heater that is powerful and has fast heating abilities. This way, you won’t have to wait long for the pool to reach your desired temperature.
- Climate – Climate plays a major role in deciding what type of electric pool heater is right for you. In general, the colder the climate, the more heating capacity you will need. If you live in an area with warm weather year-round, you may only need a small amount of heating, or possibly only at night. On the other hand, if you live in a climate with cold winters, you will need a heater with more power to maintain a comfortable temperature.
- Wattage – When shopping for an electric pool heater, it’s important to pay attention to the wattage rating. A higher wattage rating indicates a more powerful heater, which will result in better performance. This is especially important if you live in an area with cooler weather, as you’ll need a heater that can generate enough heat to keep your pool comfortable. Additionally, a more powerful heater will heat up your pool more quickly, so you won’t have to wait as long to enjoy a swim.
- Temperature Range – As anyone who has ever taken a dip in a pool knows, the temperature of the water can make a big difference in how enjoyable the experience is. If the water is too cold, it can be uncomfortable and even painful to swim in. On the other hand, if the water is too hot, it can be unpleasant and cause excessive sweating. For this reason, it is important to check the temperature range of your electric pool heater to ensure that it can offer temperatures as you need. Depending on the model, electric heaters can offer a wide range of temperatures, from 70 °F to 104 °F. If you have a specific temperature in mind, be sure to check the heater’s specifications before making a purchase.
