Combined heat and power (CHP) has long been seen as advantageous in todays’ energy producing environment. The capture and use of combustion heat in generating power is the basis of CHP. Inherently, CHP systems are more efficient than a generator that does not capture the heat.
Smartwatt®, the EnviroPower™ (EP) system inverts the CHP model by establishing itself as a heating unit that generates power. A greater percentage of the fuel consumed goes to heat. The result is a very high efficiency system. During prototype testing our average system efficiency is 93% with peak efficiency at 96%. Rather than struggle to find a use for ‘waste’ heat the EP system is the heat source for a facility. Power generation, at extremely high system efficiency, is nearly ‘free’.

How it works:
An Enviro Power™(EP)micro combined heat and power (mCHP) unit provides both electrical power and heat which can be used for Domestic Hot Water (DHW) and/or hot water heating applications.
Using a single fuel source (natural gas, liquid propane, biomass, etc), an EP™ mCHP uses external combustion to burn the fuel (similar to a boiler/furnace) keeping emissions extremely low and converting the heat into on demand steam which is instantly converted into electricity via a micro steam turbine. The steam is never stored in a pressure vessel using our patent pending process. Our turbines do not require oil and have little to no maintenance. Normally wasted heat associated with electrical power production is recovered and then used in a heating application. This gives an EP™ mCHP unit extremely high total system efficiencies greater than 95%. Once the work of the steam is converted into electricity, the exhaust steam is cooled, converted back into water and stored in a water storage tank. This completes the closed loop energy system without the use of high pressure boilers. The only requirement is fuel and a heating system.
These mCHP’s seem like heating boilers?
The biggest difference between an EP™ mCHP and a traditional boiler/furnace is the electrical output. New boilers/furnaces have high system efficiencies similar to the EP™ mCHP. These efficiencies can reach as high as 98%. An option a boiler can’t provide is below market electricity to the consumer.
Similar to boilers and furnaces, an EP™ mCHP utilizes external combustion. Compared to internal combustion engines (think car engine), external combustion processes burn fuel in a combustion chamber at lower internal pressures and temperatures. This allows power production to become fuel agnostic. Enviro Power’s™ initial products will burn natural gas/propane but are not limited to only this type of fuel. By using any fuel that contains heat content, there is a significant opportunity to begin generating power with alternative fuels.
