The Pulse Hydronic Condensing Boilers transfer more heat per square inch than conventional processes. The combustion method, coupled with the condensing design, provides significant dollar savings by operating with thermal efficiencies up to 99%. They only require 90 watts of electricity during run mode. Pulse combustion is maintained through a series of positive and negative pressures, which draw in additional gas and air as required. This self-aspirating design prevents the need for a blower motor and decreases venting diameter requirements.
