Optimize cost, comfort, & carbon performance with solutions from Danfoss

EEFA Report Recommendations for Steam System Upgrades:

uInstall Multi-Sensor Thermostatic Heat Controls:

Traditional steam heat controls do not monitor apartment temperature. Rather, they respond to external temperatures -- the colder it gets outside, the longer the boiler runs, resulting in overheating and uncomfortable residents. The solution? Replace with smart, multi-sensor heat controls that monitor inside temperatures like Danfoss Thermostatic Radiator Valves.

•Reduce high energy bills

•Control tenant comfort levels

•Save money

•Happy tenants, less complaints

•Less maintenance

vInstall Orifice Plates on all Radiators:

Almost all two-pipe steam systems use radiator traps that typically fail after a few years, resulting in underheating in some apartments and overheating everywhere else. The report recommends equipping each radiator with an orifice plate; a small metal plate about the size and shape of a bottle cap. These plates obviate

the need for most radiator steam traps, never wear out, and help balance the steam system throughout the building.

•Eliminate costly radiator traps

•Durable design - install & forget

•Helps balance system

wLeverage Energy Efficiency Programs:

Government incentive programs for multifamily buildings offer an additional return on investment for system efficiency upgrades, lower utility costs, create happier tenants, and increase occupancy rates. Some current programs include:

•Con-Edison Rebate: Up to $45 rebate per TRV installed on one-pipe steam stysems. Learn more: bit.ly/ConEdRebates

•National Grid Rebate: $50 each, limit 20 per gas account. Learn more: bit.ly/NatGridRebate
