The Heating System That Makes Electricity!

Typical Installation home market

  • Connections:

  • - Gas

  • - Electrical

  • Thermostat

  • Venting

  • Condensate

  • Coolant Lines

  • - Internet

Installed by Factory Authorized Dealers (Heating/Cooling Contractors)

Gas usage and electrical savings beta sites
Gas Usage and Electrical Savings home market(Beta Sites)

  • freewattuses about the same amount of natural gas as the replaced system to make the same amount of heat

  • freewattmakes electricity as a bonus

    • beta units average 3400 kWh per year in the Boston area

    • beta units produce only 1.0 kWe versus 1.2 kWe for production model

    • projected 4000 kWh/year average with production model

The Heating System That Makes Electricity!

Reduced co2 emissions
Reduced CO2 Emissions home market

Electrical Generation Only

  • CO2 reduction could be 1to 4 or more tons per year depending on average emissions for the local grid

  • A utility could aggregate the emissions credits for thousands of installations

Based on average emissions for the New England electric grid

What can freewatt do
What Can home marketfreewatt Do?

  • Nearly double the Governor’s energy savings objective -28% immediately

  • Provide 80% of the energy and environmental benefit of residential solar electric power at 30% of the cost

  • Neutralize residential peak demand from grid

  • Produce significant amounts of on-site electric power at total costs comparable to typical residential utility rates

  • Provide automatic back-up power during grid outages

  • Widely deployable: Over 25 million candidate home sites

  • Siting challenges: None

Energy savings with freewatt

The old way – gas fired central heat and grid power home market

Typical home heating fuel use about 100,000,000 Btu/yr (2500 ft. sq. home)

70,000,000 Btu heating delivered at 70% efficiency

Typical annual electricity consumption in NY’s single family homes is about 9,000 kWh

Net average delivered efficiency of grid is 30% with line losses, etc.

Total energy needed for electricity generation is about 9,000 kWh x 3412 Btu/kWh divided by 0.3 which equates to another 102,360,000 Btu/yr

So, total energy consumption is 200,000,000 Btu/Yr.

The new way - generate 5,000 kWh/yr by replacing old heating system at 70% efficiency with a freewattMicro-CHP system

No actual increase in gas consumption due to increase in total efficiency to 90% (70% for heating with added 20% for electricity for a total of 90%)

5,000 kWhr is 55% of total electricity needed per year.

So now consuming 145,000,000 Btu/yr, i.e. 100,000,000 Btu/yr for heating and 45,000,000 Btu/yr for electricity.

55,000,000 Btu/yr saved.

Percentage reduction in total home energy use is 55/200 = 28%

Nearly double the Governor’s objective! (15 by 15)

  • Energy Security

Benefits to the homeowner
Benefits to the Homeowner home market

Choice to Make a Positive Change in Energy Use and Environmental Impact without Sacrifice

Compares to : Switching from SUV to compact

Downsizing your home

Turning off about half of all your appliances

Climate Energy freewatt vs. Solar PV home marketNortheast Residential Application

Design Basis: Reduce Grid Power Use by 50%


Freewatt provides about 80% of the benefit of Solar PV for less than 30% of the cost.

What can AEE do to help fulfill the promise of Micro-CHP? home marketLet your legislators and the PSC know that you support…

  • Net metering: keep it simple and low cost to interconnect and measure

  • Capacity Aggregation: allow thousands of homes to combine to provide dispatchable Megawatts

  • Incentive parity with “renewable” energy

  • Education

Thank You! home market
