Dual-Fuel Boilers and Water Heaters

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.
