Pros and Cons of Electric Swimming Pool Heaters

Electric swimming pool heaters are an established part of the modern home swimming pool, and these pieces of equipment are often used by private pool owners and public baths. Swimming pools can be very chilly, particularly once the summer has ended, and you may decide that the only answer is to purchase a heater for your pool so that the water can be warmed. Swimming pool heaters are designed to warm up the water so that even on cold days there is little chance of the water freezing your bones. The electric pool heater has been developed into many different types of model, so whatever size or shape of pool, you are unlikely to be disappointed in the range available to you.


Electric swimming pool heaters are the most reliable of the heaters available to the general public. Solar heaters, while they may be more environmentally friendly, are not very consistent, being dependent upon the sun. Gas heaters are less clean than the electric heater, and may also be unreliable in colder days, as they may be affected by frost, and valves may become leaky. Gas bottles which are left outside over the winter can even become unstable when being used, and this is also a serious problem.


Electric swimming pool heaters are considerably cheaper than their gas and propane counterparts. Solar panels are the cheapest, but as described they may only work for part of the time. The actual heaters and installation is less costly for the electrical version than any others, but gas and solar panels are both less expensive when being used. In order to get the best from your electrical pool heater, you may need to moderate the amount of use, in order to save money. In terms of environmental cost, solar panels here outclass electric swimming pool heaters in every respect, but their use is limited. Gas heaters, on the other hand, leave a much larger carbon footprint than an electric heater.

Heating Power

Most electrical heaters function by drawing in air from the environment close to it, and while this works very effectively during the summer, as the air is already warm enough to be sufficiently heated by the motor. However, during winter some may find that the heater does not have enough power to warm up the pool, there will be much more cold water than the average heater can manage. As the heater has to warm up the air as well as the pool, there is not usually enough power to manage it. Like the solar panel, and also like the gas heater, there are some problems with heating during the winter, although the electrical swimming pool heater is still more reliable than the other versions.
