Heating A Pool Using Solar Panels With Heat Exchanger

Solar pool heating panels use solar thermal technology to heat pools.

Heating a pool using solar panels with heat exchanger.

Keep the solar panel out of the wind as much as possible. Heat exchangers allow heat from a. These heat exchangers can handle the higher secondary side flow as well as the high levels of chlorine and also have better flow characteristics making them ideal for solar pool heating or solar hot tub heating. This works with the use of a heat exchanger in the airflow of your forced air system.

Liquid to liquid a liquid to liquid heat exchanger uses a heat transfer fluid that circulates through the solar collector absorbs heat and then flows through a heat exchanger to transfer its heat to water in a storage tank. The heat exchanger has metal fins that allows the collected solar heat to be dumped into the air where it s circulated into the ductwork. A swimming pool heat exchanger uses hot water from a boiler or solar heated water circuit to heat the pool water. Solar water heating systems use three types of heat exchangers.

Heat is transferred by conduction through the exchanger materials which separate the mediums being used. Right now an unglazed solar system can heat a pool to 78 85 degrees fahrenheit without much effort. That s assuming your system operates efficiently which most do. A solar pool heating system usually costs between 3 000 and 4 000 to buy and install.

Solar pool heating panels last about 20 years so in that scenario you could be looking at about 17 years of cost savings. For applications that use salt water we recommend the titanium version of the solar pool heat exchanger. It s even possible to use a solar thermal system to heat a home with forced air heating. Pressure drop across both sides of the heat exchanger.

This provides a payback of between 1 5 and 7 years depending on your local fuel costs. Running it longer will result in more heat in the pool. This is a very simple and efficient process. Three variables are important in transferring energy when using a solar heat exchanger.

Solar radiation is absorbed and heat is transferred from the panels to the pool water within. Area of heat transfer surface separating the two liquids. They also typically last longer than gas and heat pump pool heaters. If you want to use two or more solar collector panels connect them in parallel.

Selecting a solar pool heater. For best heating results run the pool pump during the sunniest time of the day. Solar pool heating panels can convert as much as 85 of the sun s energy hitting them into heat energy that is transferred to your pool. Flow rate of the two heat transfer fluids.

Propane pool heaters for an average 400 000 btu heater with a price tag of over 2200 it will cost you about 10 per hour to run assuming the heater consumes around four gallons of propane in an hour of use and propane averages about 2 50 per gallon as of the time of this writing it will heat your pool about 5 degrees in that amount. Used for solar pool and hot tub heating applications.
