First Hour Usage ( 15 min shower usage):

1) Metallic Electric Resistance Heating Elements with Storage (Tank type heater)

50 Gal tank storage dual elements 2 x 4.5 kW @ 1.5 GPM x 15 min = 22.5 Gallons used

(non-simultanous mode – 4.5kW heating element cycle one at a time)
Recovery Mode: 22.5 Gal @ 30GPH – 0.50 GPM/min = 45 minutes (0.75 hr x 4.5kW/h) = 3.375 kWh
Non–Simultanous Mode (4.5kWh) Total = 3,375 Watts

(simultanous mode – 9kW {2 x 4.5kW} heating elements on at same time)
Recovery Mode: 22.5 Gal @ 40GPH – 0.66 GPM/min = 34 minutes (0.57 hr x 9kWh) = 5.1 kWh
Simultanous Mode (9kWh) Total = 5,100 Watts

2) Non–Metallic Electric Quartz Infrared Heating Elements without Storage (SioGreen Tankless)

17.6 kW @ 1.5 GPM x 15 min = 22.5 Gallons used
17.6 kW @ 60°F rise x 0.25 Hour = Less modulation @ 8 kWh = 2 kWh measured
Recovery Mode: 0 Watts
Total = 2000 Watts


Example of Cost: Estimated cost per single 15 minute shower for the consumer:

1) Tank Type

Non–simultanous mode – 4.5kW heating element cycle one at a time
3.375 kWh x $0.11/ kWh = $0.37 per shower

Simultaneous mode – 9kW {2 x 4.5kW} heating elements on at same time
5.1 kWh x $0.11/ kWh = $0.56 per shower

2) SioGreen Tankless
2 kWh x $0.11/ kWh = $0.22 per shower

Energy Usage Tank(Metallic Electric Resistance Elements) vs. Tankless(Non–metallic Electric Quartz Far Infrared Elements)

Example based on DOE National KW Average of $0.09/KW.

For 15 min shower comparison:

Tank Heater (3.375kW) x $0.09 KW= $0.30/per shower
Super Green Tankless (2kW) x $.09 KW = $0.18/per shower
(Tankless cost $0.18 vs Tank type cost $0.30) = $0.12 or 60% savings per shower


The higher efficiency of the tankless quartz heater consumed 60% less energy to perform the same task. The tankless achieved a net savings of $0.12 to the consumer for a 15 min shower compared to a 4.5 kW tank heater . In addition, by simply eliminating stand–by heat loss alone, the energy consumption can often be reduced by an additional 20% to 30% when the tankless is not in use.
