Its intelligent water channeling facilitates the condensation process and created even greater energy efficiency (up to 98%). The SB615 utilizes standard US burners and conventional controls and is a perfect match with thermostream boilers in multiple boiler systems. The SB615 and the SB735 are constructed with stainless steel fire tubes and a full three-pass flue design extracts latent heating and maximizes overall efficiency. Its simplified system design eliminates the need for dedicated boiler pumps, bypass and or shunt pumps.
