Buderus BoilersIf it’s time to upgrade your home’s outdated heating system… it’s time to talk to the Mercury Professionals about Buderus. Buderus heating systems are designed in Europe, where fuel costs are considerably higher than in the United States and environmental regulations are more stringent. Their superior design and construction maximize the heating value of every ounce of fuel – whether in operation or on standby.

In fact, Buderus produced the world’s first low-temperature hydronic heating systems. Today, Buderus products are acknowledged as the world standard in high-efficiency, low emission hydronic heating.

Dependable Craftsmanship
For over 60 years, Thermo Products, makers of Thermo Pride heating and cooling equipment, has listened to your concerns about comfort and has met your demands for the best, most reliable, and efficient furnaces and cooling systems. When you want to experience exceptional comfort, increased efficiency, and handcrafted quality along with the proven warranty of Thermo Pride, but have limited space, select the low profile OH6 or OD6 oil furnaces. You’ll be sure to receive quiet, reliable, long lasting performance from your home heating system that is specifically designed to meet your home’s needs.


Comfort is the purpose behind any heating system. “Temperature rise” makes the difference between feeling warm, comfortable air from the registers in your home or the feeling of cool air blowing across you when the furnace is on. It is the difference in air temperature from the point where it enters the furnace to the point where it exits. The  higher the temperature rise then the warmer the air is when it enters the rooms of your home. Thermo Pride achieves a 70°F temperature rise across our full line of oil furnaces. This is an air temperature up to 30°F warmer than the competition—providing a far superior comfort level.

Handcrafted Quality
Each Thermo Pride cabinet is powder coated inside and out after it is formed for a durable, tough finish that will ensure long life and a quality appearance. The interlocking insulated furniture grade steel cabinet helps retain heat within the furnace and prevents annoying vibrations during operation. The rounded corners add structural strength and a pleasing appearance to the cabinet. The heat exchanger is fabricated of 13-gauge copper coated steel in a unique octagonal shape to increase surface area and the heat transfer of the heat exchanger. The copper coating helps prevent corrosion from damp external conditions. This unique combination of design and material provides Thermo Pride oil furnace owners with the confidence that these furnaces are made to last a lifetime!

The proven longevity of Thermo Pride’s heat exchanger, combined with the Limited Lifetime Warranty, virtually eliminates the worry of ever having to replace your furnace. Should you sell your home, the warranty will automatically transfer to the new homeowners. Thermo Pride furnaces also come with a “Peace of Mind” 10-year parts warranty. You have the opportunity to extend this warranty to include a 10-year labor warranty.

We’re proud that Thermo Pride furnaces are manufactured in the United States out of American steel. Thermo Pride oil products have also earned the industry-respected certification for safety from Underwriter’s Laboratory.
