HEAT PUMP TECHNOLOGY
• Concept
• History
• Design
• Integrated Design
• Energy Savings
• NAECA Standards 2015
HEAT PUMP OPERATION• Use of
condenser side for heating
• Use of evaporator side cooling
• Has been effectively applied to water heating
• Domestic• Pool• Residential• Commercial
ECU SYSTEMS
• Field Installed ECU System
ECU SYSTEMS• Popular in late 1970’s and 1980’s• ECU = “Energy Conservation Unit”• Utilized an external Heat Exchanger and
Circulating Pump or Passive• Very Effective in Florida• Users could operate 10+ months per year
on ECU only• Huge savings on electricity• Reduced stress on Heat Pump or A/C
HYDRO-HEATING SYSTEMS
HYDRO-HEATING SYSTEMS• Popular in late 1970’s and 1980’s – still alive and well• Utilized the water heater (typically gas-fired) for heating
the home• Use stored energy in water heater to circulate a heating
coil for domestic heat in winter months• Open Loop domestic hot water• Hot Water inside coil – Air blown across outside of coil• Incorporated with “straight cool” systems• Eliminated use of heat strip electric heating• Reduced Electrical cost• Increased Gas cost• Very effective dehumidification• Integrated “Apollo” systems (water heater, heating coil
and pump) introduced
HYDRO-HEATING / RADIANT• Packaged systems are sold
today that include the heating source (Tankless or Tank-Type Gas) and a “straight heat” coil.
• Radiant panel heating is also very popular today – consists of PEX tubing in slab or wall, under tile, etc. with circulated hot water in tubing
• Other methods such as Geothermal, Water Source Heat Pumps, “Combi” Hydronic Boiler with Indirect Storage Tank, Solar

The Premier® Hybrid Electric is an integrated system that utilizes heat pump technology to pull heat from the surrounding air and deposit the heat into the tank.In “efficiency” mode, the water heater operates in the following manner: A fan brings air through the top air filter
Heat in the air is absorbed by the refrigerant inside the evaporator coil
The refrigerant is pumped through a compressor, which raises the temperature
Hot refrigerant is circulated through the copper coil and transfers heat to the
water

ADVANCED ELECTRONIC CONTROLS
OPERATING MODES
HIGH EFFICIENCY• Hybrid electric design: Integrates heat pump
technology– Conserves energy; less than half the cost
to operate compared to standard electric model
• Standard electric units are .93 to .95 EF
– Hybrid Heat Pump - The only type of electric water heater that is ENERGY STAR® qualified
• 66 and 80 Gallon Models• 2.3 EF
• 50 Gallon Model• 2.78 EF
