Honda and Climate Energy Begin Retail Sales of freewatt Micro-CHP Home Heating and Power System

American Honda Motor Co., Inc. and Climate Energy, LLC have begun retail sales of freewatt, their collaborative Micro-sized Combined Heat and Power (Micro-CHP) cogeneration system for homes.

The freewatt Micro-CHP system consists of an MCHP cogeneration unit developed by Honda paired with a furnace or boiler produced by Climate Energy. The ultra-quiet MCHP unit—based on Honda’s GE160EV natural gas engine—produces 3.26 kW of heat and 1.2 kW of electric power.

In relation to energy costs, Climate Energy test data has shown that when the freewatt Micro-CHP system replaces a typical 80% efficiency home heating system, homeowners can realize an average of 30% in energy cost savings.

The electric power produced displaces electricity that consumers would otherwise purchase from the local electric utility, saving $500 to $1000 per year on their electric bill. An additional financial savings benefit of utilizing the freewatt system is realized through the process of net metering. In states where legislated, net metering allows homeowners to sell unused electric power back to the power grid in their community, providing additional savings.

The system produces 30% less carbon dioxide emissions than a conventional heating system with electricity provided from the grid, according to Honda.

Initial sales of the heat and power units will be targeted at customers living in the Northeastern United States in conjunction with select local utility providers. The geo-targeting is due to the cold climate and high heating demand in the region which allows the system to provide the greatest benefit. The freewatt Micro-CHP systems will only be available through certified, trained, and authorized Climate Energy installation professionals.

Climate Energy and Honda plan to gradually expand production and sales of the freewatt Micro-CHP system and plan to introduce the system to other cold weather climates in the US in the future. The units will be assembled domestically in the United States with components supplied by both companies. Currently, a similar version of an MCHP system is retailed in Japan, with more than 45,000 units sold to date since its introduction in 2003.




I am interested in combining air heat pump tech, heat exchanger tech and electric power generation.

I live in a bog standard 100 yr old brick terrace with two chimmney brests four chimmneys..

The idea is to use a reversible air heat pump located in attic instead of a heat exchanger to recover heat lost in ventilated air.
(want to use the old fireplace chimmneys as air vent extraction point)
This will draw in hot air from chimmneys and from outside cooling it and producing warm 60'c water
- in a sealed UFH system for the ground floor..
with in/out pipes chased into the chimmney brests
using them as heat/cold store.
- also in a closed tank that pre warms water for input into my existing combo boiler..
Hopefully the boiler should hardly ever need to
'flame on' saving me gas.

This should save money on heating and help to cool global warming just a tiny bit :-)
But air heat pumps are most effective when you don't need heating in the summer?

So is there anyway of producing electric power from the 60-70'c water this air heat pump could produce in summer?
Anyone know of an existing system?
Have thought maybe using the boiler to run a small closed steam turbine. Anything like this exist?
Did see a solar steam project for africa using solar mirror collector.. but that wasn't in production.
have read about rankine and stirling heat engines
also about reverse compressor turbines?

Anyone got any ideas for an easy add on el. generator?
