Geothermal Systems From WaterFurnace Support Messages of Earth Day and National Indoor Comfort Week

FORT WAYNE, IN--(Marketwire - April 22, 2008) - As Americans observe Earth Day April 22 and National Indoor Comfort Week April 20-26, they hear messages that promote environmental protection and encourage them to learn more about the systems that provide comfort in their homes. Geothermal systems from WaterFurnace (TSX: WFI), the leading manufacturer of geothermal and water source heat pumps, support these messages by offering Earth-friendly heating and cooling solutions that use a clean, renewable energy source to conserve energy, reduce operating costs, improve indoor comfort and protect the environment.

-- Geothermal systems use the renewable solar energy stored below the Earth's surface to provide free, geothermal energy that increases the efficiency of home heating, cooling and hot water systems in a proven, cost-effective way, saving homeowners as much as 70 percent for heating, cooling and hot water costs.

-- The system operates by transferring energy via an earth loop connected to a geothermal unit inside a home. In winter, the system absorbs heat from the ground and transfers it to the home. In summer, the process reverses, collecting excess heat from the home and transferring it to the ground.

-- The system uses this excess heat to generate free hot water, reducing annual hot water costs by 30 percent.

-- Because these systems do not burn fossil fuel to create heat, they generate no carbon dioxide, carbon monoxide or other greenhouse gases.

-- Geothermal systems minimize the threats of acid rain, air pollution, the greenhouse effect and global warming, problems directly linked to the burning of fossil fuels.

-- The system requires only a small amount of electricity to power a compressor and small circulating pumps, reducing the average home heating and cooling energy consumption by up to 70% percent.

-- Geothermal systems help reduce peak load demands on electric utilities, also reducing the need for natural resources like coal or gas used to generate electricity.

-- By providing these green advantages, geothermal systems also help interested homeowners and facility managers achieve Leadership in Energy and Environmental Design (LEED) standards (established by the U.S. Green Building Council) that measure a structure's sustainability.

-- WaterFurnace uses the latest "green" technology to provide the highest performance ratings in the industry, qualifying homeowners for tax credits, where and when available.

-- The U.S. Environmental Protection Agency has named geothermal as one of the most energy-efficient, environmentally friendly technologies currently available.

-- Geothermal systems can be used in new construction and retrofit projects, for home and commercial applications.

-- WaterFurnace's 115,000-square-foot headquarters serves as a model for commercial geothermal installations worldwide, with 41 WaterFurnace units and a pond loop meeting all the facility's heating and cooling requirements.
