Ted Bayne and Lea Delacour live on Martha's Vineyard in
a 3,000 square foot home heated by radiant floors and a Viessmann
propane boiler. Their goal was threefold – to find a heating source
that would make their existing 90% efficient heating system more
economical to run, would not involve destroying their extensive
gardens with a geothermal installation, and would use electricity
to operate – making their home ready for the “all-electric” island
that Martha's Vineyard will become in the near future.
Until the arrival of the Daikin Altherma, there was no realistic
or cost effective way to meet these goals. The Daikin Altherma provides
geothermal levels of efficiency at a much reduced installation cost
and can operate all winter long. They contacted Nelson Mechanical
Design (NMD) to design, engineer, and install an innovative heating
system that would meet their three goals. NMD recommended the Daikin
Altherma as the solution that uses electricity, operates at geothermal
efficiency levels of 200 to 400%, has a tiny outside footprint,
and heats water for the home's radiant floors and domestic hot water
system.

| : NMD is Martha's Vineyard and
Nantucket's "green" mechanical contractor, designing and
installing geothermal, solar thermal, heat pump, and conventional
HVAC systems, plumbing, and control systems. They designed and installed
the mechanical systems for the Vineyard’s first two LEED for
Homes residences. Several of their projects have won national awards;
they were awarded 1st place in “Most Innovative Green Design”
and 2nd place in “Best Residential Green Design” in
the 2009 nationwide Green Mechanical Awards held at GreenBuild 2009
in Phoenix, AZ. Their solar hot water systems include the island’s
largest residential solar hot water system (20 panels) and the first
and only commercial solar hot water installation (Atria Restaurant).
They have received state and federal funding to conduct wind turbine
feasibility studies on two island farms as part of their “Massachusetts
Electric Farm Model”. |

Mechanical Design, Inc. is pleased to announce the arrival of “Geo-Balls”
on Martha’s Vineyard. A “Geo-Ball” is an innovative
approach to geothermal installations – when used in a horizontal
geothermal field, a “Geo-Ball” reduces excavation costs
by up to 30% compared to a conventional geothermal field.
