E.W. Leonard and Robur
Corp. Provide a Green HVAC Solution in NH.
New Horizons for New Hampshire, a
homeless shelter serving greater Manchester needed innovative
answers to solving their heating and cooling needs. the
shelter never had air conditioning, and the need for a green
solution was never greater. They serve over 900 people per
year at their facility.
impetus for seeking a new HVAC system was a desire to cut
heating costs and provide air conditioning for this non-profit
organization. The load requirements are 600,000 Btus
heating and 25 tons of cooling.
Clark Peters of E.W. Leonard,
manufacturers' rep company and Jeff LaPointe of wholesaler
distributor F.W. Webb put together a specifications for the
The equipment list includes 5
Robur heat pumps; 2 Imperial HRVs; 3 Myson hot water/chiller fan
coils units; First Company air handlers for large spaces; a
thermal mass tank and 2 back-up Rinnai wall hung units along
with 2 storage tanks.
The project is a $249,000 makeover
that replaces and antiquated oil burning system with one that is
estimated to be 40% more efficient. The natural gas and
solar sources use five soar panels and a collector system with
240 gallons of potential hot water storage.

The old system used an
out-dated oil fired steam boiler connected to steam heating units.
The entire heating and hot water energy distribution system is
fueled by solar and natural gas. Eighty percent of the
ductwork is new, although existing ducts were utilized where
The ROBUR Gas
Absorption Heat Pumps are also GREEN units because emissions are
reduced by 9,300 pounds of C02, which is equivalent to those
absorbed by 599 trees or to those produced by 2 green cars.
Gas Absorption Heat
Pumps combine the advantages of the two most common heating
technologies; gas boilers and electric heat pumps. They offer
all the advantages of boilers because: they are fired by natural or
propane gas; they don't use any refrigerants harmful to the
environment and they are easy to install. They also offer all
the advantages of electric hat pumps because they use renewable
energy ,such as air ground and water; they can supply chilled water
for cooling in summer and hot water for heating in the winter
(reversible type) and they are suitable for outdoor installation and
they don't need mechanical room (air-source).
principle is similar to traditional electric heat pumps. The
main differences are the se of a gas burner instead of an electric
compressor and the use of a water-ammonia solution instead of a
refrigerant harmful to the environment, as is the case of most
electric heat pumps.

Robur equipment, E.W. Leonard also supplied three Imperial heat
Recovery Ventilators to the new Horizons project. Imperial
Manufacturing Group's remarkable story began with an entrepreneur
