Daikin Altherma Heat Pump systems available soon on Martha's Vineyard

The Daikin Altherma heat pump uses the stored solar energy in the outside air to heat water up to 130°F – even during the middle of winter. This heated water can be used for radiant heating systems and domestic hot water. The Altherma heat pump is also designed to work with solar hot water panels to create a truly energy efficient heating system.

The Altherma is a revolutionary air to water heat pump that will make combustion obsolete! We are getting a demo unit for Living Local on Oct 3rd – first time this unit has been shown in US outside a brief appearance in Chicago in January. It will be released in October for sale.

Operating costs will typically be half the cost of operating a similarly sized fossil fuel boiler – for example, if a home currently used $4,000 in propane a year with a boiler or furnace, the Altherma operating cost would be $2,000 in electricity a year with no propane bill.

The efficiency of the Altherma meets or exceeds that of geothermal heat pumps. Because with the Altherma there is no need for a geothermal field, the installation price will be about half that of a geothermal system. This heat pump represents a truly revolutionary advance and will be an essential part of the effort to make our island energy efficient and all electric.

From Martha's Vineyard Times
When it comes to alternative energy choices, some Islanders look no further than the ground beneath their feet. Geothermal energy provided by heat absorbed in the earth from the sun offers them a free, clean, renewable energy source for heating, cooling, and water heating in their homes and businesses.

Two of the Island's biggest geothermal enthusiasts are Brian Nelson and David Sprague, co-owners of Nelson Mechanical Design.
