Company History

The Puget Sound community's #1 locally owned heating oil company for over 80 years.
Taking pride in our work and our commitment to our customers. We don't go home until everyone is warm. Rossoe provides the
'Greatest comfort for the least cost'.

Since 1928 Rossoe Manufacturing Co. designed, manufactured and distributed oil, gas and electric heating equipment throughout the Pacific Northwest, thousands of which are still keeping homes warm.
The #1 locally owned oil heating company in the Puget Sound community. Rossoe is the #1 oil, gas and air conditioning equipment, service and repair company. The leading research company since 1928 and now into the 21st century.
Rossoe Energy Systems is always looking for new ways to provide better service for our customers. Some of the areas we are investigating:
  • Researching oil powered fuel cells for homes to individually produce the electricity they require.
  • Combination burners that can burn oil and natural gas, whichever is less expensive.
  • Investigating the sale of natural gas to homeowners when gas utilities are deregulated.
  • Testing the means to improve air quality in homes for better health.
