Dual-Fuel Boilers and Water Heaters

Catalog No.: 1000.20A Effective: 07-10-08 Replaces: 01-10-06

Rising energy costs, regulations and utility incentives have

increased the demand for dual-fuel appliances. Many state

and local regulatory agencies require “dual-fuel” capability for

critical facilities, such as hospitals and schools, to ensure

emergency operation. Until now, the typical equipment solution

for domestic hot water supply and hydronic heating have been

gas/oil water heaters and boilers, or propane-air blenders, both

of which are costly to install and maintain.

Cost factors are also driving the demand for dual-fuel

appliances. Companies with rapid fuel-switchover capability

can take advantage of discounted rates being offered by gas

utilities throughout the United States for interruptible fuel

supplies. Then there’s the rising cost of fuel, making the ability

to switch fuels in response to pricing an attractive proposition.
