The HBXB-HW air handler is designed for use with today's high efficiency split system condensing units, heat pumps, hot water boilers, and tank-less water heaters. Multi-function micro-processor circuit board blower start relay eliminates field installed boiler relay, allowing direct wiring from the boiler …
Measurement of Domestic Hot Water Consumption in Dwellings
Capable of Heating, Cooling and producing Hot Water Capacity measured in tons One ton of capacity = 12,000 BTU per hour (Cooling or Heating) Typical new home is about 4 – 5 tons of heating capacity & 2 tons cooling Typical Classroom is about 2 – 3 tons of heating or cooling capacity What are Heat Pumps?
Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently available. To learn more about furnaces, boilers and other types of home heating systems, explore our Energy Saver 101 infographic on home heating .
The water consumption consists on the control of the make-up water, the blowdown water and the condensed water quantities. These three waters determine the cycles of concentration that can be reached in the cooling tower. The mass balance of a cooling tower system can be written as the following: Make-up = Blowdown + Evaporation loss
• Every ton of cooling (12,000 Btu/hour) requires evaporation of 1.5 gallons of water/hour cooling tower water usage by 20 percent. 26 Savings Potential From Increased Cycles. Sample Chemistry Report 27 Hot water boilers • Open systems provide hot water for end uses such as
