Up to 60% Savings in Water Heating Costs
It is really just basic math.
(Based on a typical 15-minute shower using 22.5 gallons of water – 1.5 GPM)
Standard 50 gallon tank type with (2) 4.5 kW Metallic Electric Resistance Heating Elements
Recovery Mode: (2) 4.5 kWh heating elements in simultaneous mode - Cold water replaces hot water in the tank heater and takes 34 minutes at full power to reheat the water. (Standby Mode not included in calculation) Recovery Mode: 22.5 Gal @ 40GPH = 0.66 GPM/min = 34 minutes (0.57 hr. x 9kWh) = 5.1 kWh
5.1 kWh x $0.135/kWh = $0.69 Per Shower
The SioGreen Quartz Infrared Tankless Water Heater
Actual Run Time - 15 Minutes: 17.6 kW @ 60°F rise x 0.25 Hour – Actual metered usage with modulation @ 8 kWh = 2 kWh metered usage. Recovery Mode: None = 2 kWh
2.0 kWh x $0.135/kWh = 0.27 Per Shower
These savings are real...$0.42 or 60% savings on every shower!
