SolarAttic PCS2 Pool Convection System Solar Heat Exchanger
Solar Without Panels: SolarAttic, Inc. has engineered the Pool Convection System 2 to heat your swimming pool using your attic and roof as a source of free energy. When your attic gets hot, the SolarAttic Swimming Pool Heater can add six weeks on to each end of your swimming season and can raise your pool temperature 10-15 degrees over a non-heated state. That means your family can enjoy the swimming pool without having to pay high heating bills. You get the benefits of solar pool heating without roof mounted solar panels.
Basic Operation: The simplified graphic diagram to the right shows how the PCS2 works. When the sun shines, the roof acts as a large solar collector. Heat accumulates inside the attic. The PCS2 safely uses this attic heat to warm your pool. It eliminates the need for solar roof panels. AND, as it heats your pool, it cools your home! This house cooling effect can lower air conditioning costs 25% or more.
Description of Technology: Solar radiation strikes the roof and reaches the attic through a process called "conduction." The SolarAttic pool heater is physically located inside the attic and then transfers this solar radiation from the attic air into the swimming pool's water through a process called "forced air convection."
Automation: Full Automation is achieved by using an optional solar controller. When the attic is 8° [LX220] warmer than the pool and the pool needs heat, the solar control automatically routes water up to the PCS2 and turns it on. The solar control can also synchronize the pool pump turning it on at the same time. Temperature sensors sense the pool and attic temperatures. The pool owner sets the desired pool temperature setting and maximum heat extraction in the attic occurs automatically. Note: The pool pump must be turned on during the time the PCS2 is turned on to effect heat transfer.
Notice: Purchasing the SolarAttic solar pool heater PCS2 heat exchanger by itself assumes that you have the support equipment locally to either run it manually or automate it. The solar pool heater PCS2 will work with all standard solar control systems. Programmable controls require that the solar pool heater be programmed in order to operate. The solar pool heater heat exchanger requires a bypass valve for manual operation at a bare minimum. Plumbing it directly into the pool support system and simply turning it on renders the system ineffective since it will both heat and cool the pool depending upon temperature conditions. Cooling can offset the heating and that is why SolarAttic recommends automating its solar pool heater. Note: Linear temperature sensors in programmable controls must be properly wired through the solar pool heater's internal float or else the system will not turn on. This requires observing the polarity of the linear sensor.
