Gas-fired pool heaters remain the most popular system for heating swimming pools. Today you can find new gas-fired heater models with much higher efficiencies than older models. Still, depending on your climate and pool use, they may not be the most energy-efficient option when compared to heat pump and solar pool heaters. Gas pool heaters use either natural gas … continue reading →

Most Energy Efficient Natural Gas Swimming Pool Heaters

The efficiency of natural gas swimming pool heaters are measured by their output in Btu (British thermal unit) and is determined by a standard test. Heater efficiency is the ratio of usable output to energy input. For example, an 80%-efficient heater uses $80 worth of useful heat for every $100 worth of fuel. Therefore, it … continue reading →
