How a Swimming Pool Can Reduce Pool Water Heating Cost Substantially

by Pool Builders on 03-18-2013 in Articles

It is not uncommon to see a swimming pool today that's installed with a solar hot water system even though the initial purchase price is higher compared to a non-solar water heater system. Lots of homeowners these days already know and understand the many benefits of harnessing the sun's energy. Hence, they are willing to spend for a high installation fee because they know that the savings in energy bills will generally pay for the difference in the long run.

Solar hot water systems generally have a longer lifespan than a conventional water heating unit. This is also another major factor that made some people go for it apart from the financial returns. The initial cost for a solar hot water system installation ranges from $3,000 to $10,000. A system that's apt for an average household will cost around $4,500. This is the cost before rebates as the state and federal government offset the initial cost of installation.

Flat panel and evacuated tube collectors are used as solar collectors that work to attract energy from the sun. Pool water is heated by the sun's energy as it passes through the collectors before it flows into an insulated storage tank. This transfers heat to the water tank passing through a heat exchanger. Hot water flows into storage tanks through a passive or active system.

In passive systems, the water storage tank is positioned above the solar collectors, so that the cold pool water sinks into the collectors and warmed before it goes up into the tank. In active water heating systems, the solar collectors are located on the roof whilst the storage tank is placed on the ground. The pools water is pumped via the solar accumulators aided by a small electric pump. The pump runs using a temperature sensing controller.

Swimming pools installed with solar heating systems are usually built with water storage tanks that fitted with electric or gas fuel booster for water heating purposes when the heat from the sun is not enough. Boosters are only used at certain times of the year, such as in winter. Hence, the overall energy savings of installing a solar hot water system per year will offset your pool water heating costs substantially. It also helps a lot to place the solar heating system near wet areas if you want to save on energy costs as cool areas helps reduce heat loss in the pipes. To further reduce the amount of heat loss, insulate the piping line.

Some owners of swimming pool still prefer the use of electric heating. For them, it is the only option especially when they are in an area with no access to natural gas. In reality, it doesn't matter what the type of heating you have installed for your pool as all water heating devices have equal efficiency in turning electricity into heat. So, before you go ahead and proceed with your heating device installation, consult your builder on the best system that will work best for your pool type and location.
