Why Bergen County Pool Owners Choose This Product

Our Northeast climate demands reliable heating to maximize your investment. Bergen County pool owners rely on these heaters to extend our brief summer season and enable comfortable evening swimming. Energy-efficient models particularly valuable here, where heating costs can quickly add up during our unpredictable spring and fall weather.

Installation Considerations

Gas heaters require proper venting and must meet local clearance requirements from combustible materials. Heat pumps need adequate airflow (minimum 6 inches clearance) and should be protected from wind. Professional installation required for gas connections.
