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: Simultaneous
-
22.5 Gal @ 40GPH – 0.66 GPM/min = 34 minutes (0.57 hr. x 9 kW) = 5.1 kW (Simultaneous mode – 2 x 4.5 kW heating elements - 9kW) Total = 5,100 Watts - 5.1 kW
Recovery Mode: Non-Simultaneous
-
22.5 Gal @ 30GPH – 0.50 GPM/min = 45 minutes (0.75 hr. x 4.5 kW) = 3.375 kW (Non–Simultaneous mode - 1 x 4.5 kW heating element - ) Total = 3,375 Watts - 3.75 kW
-
Maximum Cost per Shower - 5.1 kW x $0.135/kW/h = $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 kW = 2 kW metered usage. Recovery Mode: None = 2 kW
2.0 kW x $0.135/kW/h = 0.27 Per Shower
These savings are real...$0.42 or 60% savings on every shower!
