Electrification of your DHW plant could be as simple as specifying a water heater with a resistance element. However, this can be expensive to operate over the long term with a utility cost of approximately 4 times that of natural gas water heating. Heat pumps utilize the properties of refrigerant gas to move heat into the domestic water from another medium, typically either air source or water source. These systems can have lower recovery rates so typically larger storage tanks are used along with a resistance element for final heat back-up / top–up. With our Lync, Hubbell, SHARC, and PVI product lines, we can provide a comprehensive zero emission domestic water heating package designed for your application.
Lync by Watts
The Aegis heat pump water heater by Lync uses natural CO2 / R744 refrigerant for a GWP of 1 and an ODP of 0. Lync Aegis is available in air- and water-source, along with a combination model that is air source with ‘cool recovery’. Essentially the heat pump can switch over to water source when there’s a demand for cooling in the building, saving load on the chiller for a combined COP effect. Available in commercial scale sizes from 250-500 MBH. The air source model can operate down to -20°C ambient air temperature, and provide hot water up to 82°C. Long lasting storage tanks, backup electric water heating, and digital thermostatic mixing valves are available to complete the system.
