Patent ID: 6889910

Claim:
A system for controlling a combustion environment within a combustion chamber of a hydronic heating unit, said hydronic heating unit including a boiler containing a HTF, a heating element disposed within the combustion chamber associated with the boiler means and a fluid distribution network in fluidic contact with the boiler thereby enabling movement of the HTF, said system comprising: a first heating unit for adjusting fuel temperature, wherein fuel being transferred from a fuel source to the heating element has a predetermined temperature upon arrival at the heating element, said first heating unit including a first chamber and second chamber in thermal conductive contact, whereby regulating the HTF through the second chamber enables regulation of the fuel temperature of the fuel passing through the first chamber; a second heating unit for adjusting combustion air temperature, wherein combustion air transferred to the heating element has a predetermined temperature upon arrival at the heating element, said second heating unit having a first portion and a second portion in thermal conductive contact, whereby regulating the HTF through the second portion enables regulation of the combustion air temperature of the combustion air passing through the first portion; and a third heating unit interconnected with the boiler for heating the HTF to an operational temperature, such that the operational temperature of the HTF is sufficient to adjust fuel temperature and combustion air temperature to predetermined levels prior to ignition of the heating element.
