We won’t hang you out to dry: having a pool heater can be a significant investment, but you built your pool to enjoy it when you want to, right? One of the biggest factors associated with expenses associated with operating your pool heater is efficiency.
The more efficient a gas pool heater is, the lower the cost is to operate it, and the less time it needs to run to deliver the same amount of heat for your pool water. What does this mean? If you buy $1.00 worth of gas and your heater is 82% efficient, your heater puts $0.82 worth of heat into the water. Likewise, at 96% efficiency, the ETi 400 would put $0.96 worth of heat into the water for the same price. The more efficient the heater is, the less it costs to operate.
