Hi Delta™ FlexGas™

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.

With Raypak’s FlexGas Hi Delta boilers and water heaters, natural-propane gas switchover is fast and economical. And there is no requirement for costly propane-air blenders or air compressors.
