Q:  How much does a solar pool heater cost to install and operate compared with other types of pool heaters?

A:  Generally speaking, the initial cost of installing a solar pool heater is slightly higher than a gas-fired or electric pool heater. However, while the annual cost of electricity to run a heat pump may be only two thirds that of natural gas (and far less than propane), the sun’s energy is FREE! Once a solar pool heating system is installed there are zero operating costs. That’s right, no more ridiculously high utility bills just to use your pool comfortably! In fact, over a 15-year span of heating your pool installing a solar pool heater can save you up to $28,000.

Note: The sharp increases shown for fossil-fuel heaters around years 7 and 10 indicate the purchase of a replacement heater after average lifespan.

 

Q: But, doesn’t the pump have to run longer? And it must be working harder to push all that pool water up to the roof?

Actually, a high-efficiency solar pool heating system only needs about 6-8 hours of good sunlight each day to effectively heat a swimming pool. Most residential pools already run their pump or filter at least 8 hours a day (8-12 is recommended). So, as long as the pool is being filtered, it is being heated.

There is more than enough power in today’s pumps to operate a solar pool heater without stressing the motor. Did you know a 1-horsepower pump is capable of pushing a column of water 60-70 feet in the air, without breaking a sweat? Once water is diverted up to the roof, physics tells us it has to come back down – creating what is known as a “siphon effect” – effectively helping to reduce pressure drop at the pump. In the end, the pump is simply overcoming a very minor frictional loss.

    Solar water heating is popular in many parts of the world, with installation costs varying widely from country to country. In the United States, it can cost $5,000 or more to have a system installed, though you can recover 30% of those costs through government rebates.
