Thermal Solutions has designed the high-efficiency copper-finned condensing Evolution® to meet the needs of today's commercial heating requirements. The Evolution EVCA design takes the very best of existing technology to the next level by incorporating a secondary heat exchanger. The result is higher efficiency and greater reliability in your application.

The Evolution is now being featured as a fully condensing boiler. Ranges are 750,000 through 3,000,000 BTU/hr.


..Top Reasons why you should be thinking Thermal Solutions:

Efficiency - It's 97% to the latest DOE guidelines, the BTS2000. A true rating, AHRI certified, with no gimmicks lowering return water temperatures to boost numbers. Beware of what you read...

Reliability - Proven design with installed base approaching 7 years. Have you seen how long some of these other condensing products have been on the market? You won't be a "Product Test Case" with Thermal Solutions.

Flexible - Easily integrates into existing systems or new construction with primary/secondary or varying flow requirements.

Smart - NO WELDS in our boiler; our competition is littered with 100's of feet of leakage vulnerability.

Simple -We confine acidic condensate to a cleanable, repairable, and replaceable component. Our competition exposes their entire boiler to this caustic environment; any and all leaking issues are catastrophic to their boiler and not repairable with a replacement part.

Environmentally Friendly - Lowest standard NOx offering of any boiler in its class, with half the emissions of other products. No adders or alternative burners needed here.

Low Annual Maintenance - Can you change an air-filter? No need to remove the burner for cleaning.

Backed with Commitment - 10 Year Burner warranty, you will be hard pressed to find another with more than 2 years.
