The EC-20 Series is a triple pass boiler made with a proprietary eutectic cast iron heat exchanger that is resistant to thermal shock and corrosion.  The cast iron is flexible and resilient which allows for lower temperature operation. We’ve done the testing and have matched burners and components to this boiler to make sure the boiler will stay running clean after you leave the job.

How It Works

The EC Series efficiency is a result of the boiler’s unique three pass design heat exchanger with specially designed baffles for maximum heat exchanger contact, flue turbulation and heat transfer. The three pass design of the Eutectic makes it very quiet too. There is plenty of room for thermal expansion of the flue gasses to keep burner and flame noise to a very minimum.
