Using A Solar Heater For Swimming Pool

To keep your swimming pool a source of joyful baths even in cold weather, some source of heating the pool’s water must be employed. Now a day, many people choose to install a solar heater for swimming pool. The reason behind this popularity appears to be the easy and cost-effective way by which a solar heater for swimming pool raises the pool water’s temperature, usually from seven to ten degrees, and provides a warm, comfortable feeling of bath in a free and open space.

Function Of A Solar Heater For Swimming Pool

A solar heater for swimming pool basically works by forcing water of the swimming pool through a filter that leads it into a solar collector. This contains solar heat collected from the sun by means of specially designed panels. The pool water absorbs the collector’s heat and returns into the pool through the pump. Certain kinds of solar heaters serve a dual function i.e. besides heating the pool water in winter they can be run during the night and kept off during daytime. This helps maintain a cooler water temperature during the summer days.

Price And Heating Capacity

The price and heating capacity of a solar heater for swimming pool depend on the heater’s size. The most popular size of the heater is the one with 2’x20’ panels. It costs about $150 a set. Two panel sets i.e. 4’x20’ suffice to heat a 18’-24’ round pool. If you have a 16’ round pool, you can do with smaller panels i.e. 4’x10’.


Installing a solar heater for swimming pool is fairly easy and usually takes less than an hour. What you need to do is take a hose and clamps and with these, connect the solar panel to the pump. Now roll out the panel to finish your installation. Remember that you need not mount the panels permanently. You may either simply mount them up on the roof or position them by using frames available from the dealer. On first turning on the panels, they will feel hot to touch for some minutes. After that, they’ll cool down.


Though little maintenance is required for a solar heater, keeping balanced water chemistry is important as well as keeping the filter in proper working condition.

Using solar heater for the pool is very beneficial since it is totally free after you pay the initial cost. You can also use solar heaters in conjunction with another swimming pool heater. This brings down the costs by as much as 70 per cent.

Swimming Pool Heater Adds To Enjoyment

Nobody enjoys swimming in cold water, which is why most people installing a pool opt for a swimming pool heater to keep the temperature more comfortable. Several options exist, including gas, heat-pump and solar power. Which option is chosen by the pool owner will be determined by their budget.

Understand, most swimming pool heaters operate on the same premise. Water is pumped from the swimming pool, through the heater and back into the pool where the heated water raises the temperature level of the pool water. A thermostat installed on the line into the pump records the temperature of the water in the pool and stops pumping until the temperature drops below a pre-set temperature.

How the water is heated is what determines the cost. There are two variables to consider when deciding the type of swimming pool heater is best for your pool. The initial cost and the annual operating cost. Some may offer cheaper installation costs, but prices of utilities and the climate in the area, may make them expensive to operate during the season.

Installation And Operating Expenses

Of the three main types of swimming pool heater, gas, either natural or propane, is the cheapest for initial installation. For comparison purposes an example of a 15 foot by 30 foot kidney shaped pool will be used. A gas swimming pool heater will cost roughly $1,200 and another $500 for installation. A homeowner can usually install a swimming pool heater themself, but it is highly recommended that connections for gas and electric be left to a licensed professional.

A heat pump swimming pool heater is more expensive to install, about $3,900 including installation and a solar powered swimming pool heater will run about $3,000 with installation. Their operating costs are what sets them apart.

A gas swimming pool heater will cost about $1.20 to realize a dollar’s worth of heat. On an average, it’s expected to cost between $1,000 and $1,500 per season to operate on propane. Depending on the price of natural gas in the area, it could cost about 50 percent less.

A heat pump swimming pool heater, on the other hand will cost about 20 cents for $1,00 worth of heat, bringing the annual cost of between $250 to $500 per year, which can offset the initial cost. A solar powered swimming pool heater will cost about $30 to $75 in electric to operate the pump required for water circulation, but not for the power itself.
