Pool Gas Heaters – Heating Efficiency With No The Significant Expenditures
“
However, a pool heater allows you to extend usage of the swimming pool from early spring until later into fall even in cooler regions of the country.
In warmer regions, installing heaters would make swimming pools usable 365 days in a year.
In general, there are three classifications of swimming pool heaters: gas-fired heaters that use propane or natural gas, oil-fired heaters and heat pumps. Pool gas heaters continue to be the most common swimming pool heating option. Raised consciousness of the environment and energy efficiency paved the way for the emergence of solar heaters and heat pumps.
Water source and geothermal heat pumps are also being introduced to the market although with higher first cost. Nowadays there are more efficient pool heaters compared to older systems. Advances in technology have significantly increased efficiency of traditional pool heaters. Innovations in mechanical engineering, heat exchanger technology, pilot-less ignition and hydraulics have raised the bar in heater efficiency.
