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

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
