Home & Pool Solar Heating


Finally the mercury has started to rise and days are getting longer and brighter. Clocks are turning back an hour this weekend, heralding spring and summer and of course, the first thing that comes to mind after ice cream is swimming pools and beaches.

While it may be cool until June, keeping us from spending a day at the beach, we can definitely start an earlier swimming season availing our pool of solar pool heating technology that has been bestowed upon us.

Solar heating is a simple and maintenance-free way of heating your home and pool water using the energy from the sun. Stop paying the high utility cost of standard pool heaters, water heaters and home heating.

Home Solar Heater Systems:

Before we get into Solar heaters for pools, here’s a tutorial on using solar heating in the home. Home solar systems are defined based on their type of collector and circulation system.

Home solar heating systems have three different types of collectors. All three types serve the basic function of trapping the sun’s heat and transferring it to your home, the difference lies in their design and functionality.

solar-batch-collectionBatch Collectors, also known as Integrated Collector-Storage (ICS) Systems, use insulated boxes that are fitted with dark tubes that help store warm water for long periods of time making them very practical. They can be used for heating homes, barns or garages, or for heating water for kitchen and bath.

flat-plate-collectorsFlat-Plate Collectors make use of flat absorber plates that are fitted with copper tubes and are contained within an insulated box. This type of connector is ideal for heating and storing up to 40 gallons of water, thus making them ideal for heating water in the home.

solar-batch-collectorsEvacuated Tube Collectors are the most efficient type of solar heater collector available on the market. Evacuated tube collectors consist of two glass tubes with a vacuum resulting in minimal heat loss and maximum efficiency. These types of collectors work well even on cloudy days, and can operate in temperatures as low as 40°F.

Home Solar Heater Circulation Systems:home-solar-system

A solar heater circulation system circulates the heated water through your home, to heat floors or walls, or to heat sink and shower water. There are four types of Solar Heater Circulation Systems.

Direct circulation systems works exactly as its name suggests – taking the sun’s energy directly and using it to warm water in the collector before bringing it back to the home.

Forced circulation systems make use of electric pumps, valves and controllers to move water from the collectors to a storage tank and then dispersing it to the home.

Indirect systems use a non-freezing liquid to trap heat from the sun and use it to warm water in the storage tank with the help of a heat exchanger.

Passive systems are the simplest to use; they move water from the collectors to the storage tank as it heats up and do not require any pumps to circulate.

Solar Pool Heaters

Solar pool heaters are thankfully, not so confusing. We use a closed-loop system, without a storage tank, diverting cool pool water through black rubber mats, and back to the pool return. A very simple design, which can be automated with temperature sensors and a motorized 3-way valve, and controlled by a thermostat.


Come with me to go over the various Solar Pool Heaters that we carry at In The Swim – take my word, you will find the one that meets your pool’s heating needs and your budget.

The more direct sun exposure you have, and the more solar panel area you have – the better. Depending on these two factors, you can raise the water temperature 5-25 degrees with a solar pool heating system.
