Save Money and Energy with an Efficient Commercial Water Heater
To ensure customers receive the benefits of high-efficiency, Liberty and NHSaves® have created the Commercial & Industrial (C&I) Natural Gas Water Heater Initiative, a market transformation initiative that partners with distributors to offer monetary incentives on high-efficiency water heaters to commercially metered natural gas customers.
Water heating accounts for approximately 20% of natural gas use in commercial applications. Installing a high-efficiency water heater can result in thousands of dollars in energy bill savings, provide better comfort and control, and can lower water and sewage costs.
Qualifying Water Heater Equipment
Incentives are available for qualifying high efficiency equipment in the chart below:
|Water Heater Type||Input Rating||Required Efficiency||Customer Discount|
|Storage||>= 75 Mbtuh||Thermal Efficiency >=94%||$2.00/Mbtuh|
|Tankless (On-Demand)||< 200 Mbtuh||Energy Factor >=0.94 or Uniform Energy Factor >=0.91||$1.00/Mbtuh|
|Volume (Domestic Hot Water Boiler)||>= 75 Mbtuh||Thermal Efficiency >=94%||$2.00/Mbtuh|
There are several high-efficiency water heating options available to commercial customers.
Condensing storage water heaters utilize the heat from exhaust gas to heat water efficiently. Condensing storage water heaters can support multiple, simultaneous uses of hot water and are preferred for emergency replacement situations because of the ease of installation. Field-supplied materials are limited to piping and fittings near the heater because these water heaters use the same gas line as the unit they are replacing.
On-demand tankless water heaters provide a constant supply of hot water and are not subject to standby energy loss since they heat water only when needed. Tankless water heaters are well-suited for facilities with restricted or limited space because they do not require a storage tank.
Indirect water heaters consist of a storage tank that connects to a building's main furnace or boiler to heat water. The energy stored by the tank allows the furnace or boiler to turn off and on less often, saving energy. Because they can be installed without additional exhaust piping, indirect water heaters tend to have lower installation and maintenance costs than traditional water heaters.
Condensing volume water heaters utilize heat from exhaust gas to heat water efficiently. Because they produce a high output, condensing hot water boilers can be a good option for facilities with high-volume hot water demands.Download Form
