Thermo Products, releases 95% efficient Oil Furnace

NORA R&D funding contributes to the new ultra-high efficiency appliance.


Thermo Products has developed a 95% AFUE oil condensing furnace that is Energy Star qualified and can match the AFUE ratings of gas furnaces.

Thermo Products Research and Development Department, headed by Chief Engineer, Everett James, have designed and developed this new ultra-high efficient oil furnace with funding assistance from the National Oilheat Research Alliance (NORA). “With efficiencies equal to many gas furnaces, we are excited to offer this energy efficient product to our customers”, according to Linda Keene, Marketing Coordinator of Thermo Products.

The OHC95 has a firing rate of 75,000 Btuh with up to 4 tons of A/C capacity.  This furnace uses industry standard components such as the Riello BF3 Burner. Standard ECM blower motor offers additional energy savings.

When designing this new oil furnace, Thermo Products asked themselves “How can we make this unit easier to service than our competitors?”.  Well, they have designed easy access to the primary and secondary heat exchangers by mounting them on a roller system to be pulled out. This makes servicing the primary and secondary heat exchangers quick and easy for routine maintenance. They have also designed the secondary heat exchanger with larger tubes allowing less restricted airflow minimizing buildup.

According to Rob Paquette, National Sales Manager for Thermo Products, They have had units in beta testing for some time now and even with the cold weather we have been experiencing lately, we have had no issues at all with this furnace.  One beta test site has seen fuel savings of approximately 25%.The OHC95 is offered in direct vent only using 3” PVC pipe.  The cabinet is 24W x 37.5D x 48 H with heavy 22 gauge cabinet steel with rounded door corners.  The powder-coated cabinet is black with silver front panels, which differs from the classic Thermo Pride furnace colors. Venting can be either left, up or right with an air supply opening of standard 20” x 20”.

Each unit comes with a ventor assembly. This is similar to an inducer fan on a gas furnace but it is in-line with the PVC pipe. This ventor is a sealed system venting flue gases when the furnace is running while at the same time bringing in combustion air.

The OHC95 Condensing Oil Furnace is currently available for sale. Thermo Products will initially offer the OHC95 to contractors who have gone through their online training class. They are offering the technical training to make sure the system is installed to their specifications for maximum performance and efficiency.
