Home Heating Systems that Generate Electricity

Our revolutionary Rankine cycle micro-cogeneration technology is unique in its suitabilitycogenunit.jpg (16739 bytes) for the residential and small commercial user.   It provides all of the heating and hot water needs of a home whilst also generating electricity for use in the home.  Surplus electricity can be sold into the grid.  Micro cogeneration systems, also known as micro CHP (Combined Heat and Power) systems, are thus uniquely able to provide home heating whilst earning an income.  Our technology is simple and affordable and has been designed with the comfort of the end user in mind - it runs very quietly and requires almost no maintenance.  Installation in the home is as easy as replacing the conventional boiler used in hydronic heating systems.

This technology also reduces greenhouse gas emissions and saves energy.  Widespread implementation of micro-cogeneration is arguably the most significant change that can be made in the short to medium term, to minimse climate change - refer to our micro-cogeneration discussion for the reasons.

Our production release is still a couple of years away, however, our development time and system reliability is aided by the simplicity of our technology.  No exotic materials or working fluids or Swiss watch manufacturing tolerances are involved.  We are still seeking strategic partners to assist us in getting our product into the marketplace as soon as possible.


Sales and Specifications

Unfortunately we are not yet taking orders.  We envisage that market release of our products will be in mid 2012.

We will have two sizes: a 2.5kWe unit for domestic applications; and a 10kWe unit for large residential and small commercial use.

The preliminary specifications are as follows:

Electrical Output 240V 50Hz, 110V 60Hz 240V 50Hz, 110V 60Hz
Electrical Power, kWe 2.5 10
Heating Power, kW 11 (22 boost mode) 44
Overall Efficiency 90% 90%
Weight, kg 60 175
Dimensions, mm 870h x 600w x 400d 960h x 800w x 600d


Note:  Specifications are subject to change without notice.

Pricing of these systems has not been released but our systems will be significantly cheaper than competing options.


Our Competitive Advantage

Unlike most competing technologies, we have designed specifically with the typical cogeneration application in mind.  Compared to Stirling cycle engines, our system is light and compact for ease of home installation.  And unlike internal combustion engines, it is inherently quiet, has low exhaust emissions and requires almost no maintenance.  In contrast to fuel cells, the technology is simple and affordable and ready for volume manufacture using conventional processes.

We understand that home heating boiler replacement is often a distress purchase.   It is thus critical that our system can slot straight in where the boiler came out.   And even more importantly, it must cost not much more than a conventional boiler - otherwise the payback time will be unattractive.  Our system meets these critical requirements with its simplicity.  Our innovative approach to Rankine cycle engine design eliminates many moving parts and replaces them with electronic control and actuation.  Our system uses water as the working fluid, basically making it a small steam engine, eliminating issues with exotic working fluids that require hermetic sealing and periodic replacement.  High efficiency ensures that it generates enough electricity to pay for itself rapidly.  Our domestic unit will produce 2.5kW of electricity whilst producing 11kW of heat, operating at an overall efficiency of over 90% (based on higher heating value).  Even more importantly, unlike almost all other competing technologies, our system operates at high efficiency at part load.  This is important, as heating systems are generally sized for the coldest day, so operate at part load most of the time.

Our technology is protected by a comprehensive intellectual property protection strategy.   This includes patents that cover core aspects of the heat engine technology and the control system that allows us to connect directly to the grid without the need for a costly inverter.

We also have one of the best technology development teams in the business.  Our technical team has a proven track record at developing and commercializing technology.   The team has been responsible for many successful products developed by our sister company Applidyne, a consulting engineering company, for its commercial clients.
