Ecological concerns are becoming a priority for not only governments, but to individual home owners. As we move more towards sustainable energy sources, solar heating plays a more important role.

In the USA, tax breaks are available for solar pool heating and in other states, legislation is being introduced to make it law to use solar heating as part of the pool heating system.

For example, in Southampton NY, a heated pool MUST have a properly sized solar pool heating system to maintain water at 80 degrees, a secondary source may be installed but be of the highest efficiency.

New Jersey is considering introducing "the Hybrid Swimming Pool Heating act", which would demand that at least 25% of the swimming pool heating is acheived through solar power.

Solar Swimming Pool Heating

Solar swimming pool heating has many advantages in climates where there is plentiful sun, with advances in vacuum technology and more effecient solar panels a reliable instalation is a reality.

Vacuum tube solar pool heating is extremely efficient, the tubes were designed to boil water in the Arctic circle! The tubes are so effective that the water from them can not be pumped directly into the swimming pool, it must go into a heat exchanger first.

These tubes are good because they are compact, not needing much room for instalation.

Traditional solar panels need 75% of the surface area of the pool in panels, which presents some challenges of where to put the panels.

A good solar instalation should include a temperature sensor that will start and stop the pump, its no good pumping water through the panels if they are colder than the pool water.

Evacuated vacuum tubes for swimming pool heating, are the most effecient solar heating available, but this effeciency is expensive. An instalation would be comparable to a heat pump.
