Company Background

• Ilios Dynamics Inc. was created in May 2009 as a majority owned division of Tecogen to develop and market high efficiency heating products

• Ilios products utilize advanced thermodynamic principles for recovering heat and improving efficiency

1 2012High Efficiency Water Heater 9HEWH-500-AS

• We are now introducing our first commercial product: The IliosHigh Efficiency Water Heater (HEWH-500-AS)

• With a heating capacity of 500,000 BTU/Hour and up to 180% efficiency, the Ilios High Efficiency Water Heater can cut fuel consumption and carbon usage in half

Heat Pump Cycle For Hot Water Heating

� Heat is extracted from the environment with mechanical work

� It is pumped to a higher temperature using a standard vapor

Product Concept


� It is pumped to a higher temperature using a standard vapor compression refrigeration cycle

� Natural gas engine, in place of an electric motor, provides recoverable heat to supplement refrigeration cycle heat

� Engine also drives small electrical generator so parasitic load (fan motors, pump, controls) is self-contained

� Efficiencies up to 2X of a gas-fired boilers

Product Concept


Product SpecificationHEWH-500-AS

� 400,000-600,000 BTU/Hour (4-6 Therms)

� Engine (<50 bhp)a. 2.5 L 4 Cylinder

b. Natural Gas

c. Ultra Low Emissions

� Small 5 kW generator for electrical parasitic load


� Small 5 kW generator for electrical parasitic load

� Next-generation control system• Internet-Based

• Touch-screen display

• Advanced communications (CAN)

� Efficient, low-pressure, HFC-134a refrigerant

� Open-drive reciprocating compressor

� Custom evaporator coil design

� Compact brazed plate condenser

Heat Output


Coefficient of Performance


� In June 2009, the California Energy Commission granted Tecogen additional funding of $530,000 for an ongoing program to develop and test advanced emission control systems for Combined Heat and Power. The program included co-funding of $90,000 from Sempra Energy

Emissions Development


� This work resulted in patent pending technology which virtually eliminates criteria pollutants using a proprietary two stage emission system

� Tecogen’s technology provides clean energy efficient emissions and the ability to meet today’s stringent air quality requirements

Emissions Development


� 50 % reduction in carbon footprint

� Save 100 tons of carbon annually at typical installations

Environmental Benefits


� Exceed clean emissions standards throughout the US including California

� Ultra low emissions with near zero criteria pollutants

In 2008 and 2009, two federal bills were passed with provisions that support Combined Heat and Power (CHP)

� For qualified CHP systems such as the Ilios High Efficiency Hot Water Heater, a 10% Investment Tax Credit is available for systems placed in service before January 1, 2017

Incentives


systems placed in service before January 1, 2017

� For 2012, 50% Bonus Depreciation is available under the federal Modified Accelerated Cost-Recovery System (MACRS)

� Federal incentives as well as utility incentives may significantly reduce the payback period for the Ilios High Efficiency Hot Water Heater

Product Features & Benefits HEWH-500-AS

� 400,000-600,000 BTU Outputa. Highly Efficient

b. Ultra Low Emissions

� Hot Water delivery temperature at 120F, 140F, or 160F

� Highly Efficient Heat Pump cuts heating costs and carbon


� Highly Efficient Heat Pump cuts heating costs and carbon footprint in half

� Ultra Low emissions with near zero criteria pollutants

� Simple installation to existing hot water system

� Minimal Electrical Requirements-120V 15A

� Modular & Scalable

Economic Environment

Natural Gas Rates

� Since July 2008 natural gas rates have collapsed by 75% (Source: Distributed Generation September 2012-US Energy Information Administration)

� Low gas rates favor natural gas chillers and CHP where


� Low gas rates favor natural gas chillers and CHP where electric rates are high, not gas fired heat pumps

Payback Analysis

� With natural gas, a payback ≤4 years can be achieved in buildings with significant thermal loads in the Southern US

� With propane, a payback of ≤2-3 years is possible in the buildings with significant thermal loads in the Southern US

� High fuel prices, propane (LPG) infrastructure, and focus on efficiency make Europe an important market
