3. 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

4. ECU SYSTEMS
Field Installed ECU System

5. 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

6. HYDRO-HEATING SYSTEMS

7. 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

8. 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

10. INTEGRATED DESIGN 1 2 3 4
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 1 2 3 4
