Right now an unglazed solar system can heat a pool to 78 85 degrees fahrenheit without much effort.
Heating a pool using solar panels with heat exchanger.
If you have been reading and researching about ways to heat your pool you most likely will have come across the term heat exchanger.
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.
This is a very simple and efficient process.
Solar pool heating panels use solar thermal technology to heat pools.
Solar radiation is absorbed and heat is transferred from the panels to the pool water within.
They also typically last longer than gas and heat pump pool heaters.
Selecting a solar pool heater.
For best heating results run the pool pump during the sunniest time of the day.
Flow rate of the two heat transfer fluids.
If you want to use two or more solar collector panels connect them in parallel.
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.
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.
A swimming pool heat exchanger uses hot water from a boiler or solar heated water circuit to heat the pool water.
A solar pool heating system usually costs between 3 000 and 4 000 to buy and install.
For applications that use salt water we recommend the titanium version of the solar pool heat exchanger.
Solar water heating systems use three types of heat exchangers.
That s assuming your system operates efficiently which most do.
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.
Area of heat transfer surface separating the two liquids.
Three variables are important in transferring energy when using a solar heat exchanger.
Pressure drop across both sides of the heat exchanger.
This works with the use of a heat exchanger in the airflow of your forced air system.
It s even possible to use a solar thermal system to heat a home with forced air heating.
Heat transfer fluids such as antifreeze protect the solar collector from freezing in cold weather.
Your actual cost and payback depend on many factors.
Keep the solar panel out of the wind as much as possible.
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.
Heat is transferred by conduction through the exchanger materials which separate the mediums being used.
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.
