FAQ
1. Is the engine available separately?
• No, because the minimum input is 60,000 Btu, ignition occurs at no less than 2 gpm-this is not a viable stand alone
tankless product.
2. Is this product ENERGY STAR rated?
• No, currently there is no qualification for tank water heaters over 75,000 Btu.
3. What is the energy factor rating?
• Energy factor ratings are only assigned to tank water heaters with 75,000 Btu or less.
4. Is this product eligible for any federal tax credits or incentives?
• Not at this time. The efficiency is compliant but the Btu for a tank must be less than 75,000 to qualify as a residential
water heater.
5. What happens if the demand is great enough to deplete the tank?
• If demand is 3 gpm or less, the engine will service the demand adequately. So, the unit can provide an endless supply of
hot water supply to a single standard shower or washing machine, etc.
• If demand is greater than 3 gpm, after the tank is depleted of its stored hot water, there could be a reduction in
temperature—this will be dependent on the flow and groundwater (supply) temperature.
• It is important to note that full recovery with no demand is only about 15 minutes.
6. Does the controller beep when there is an error code?
• No.
