Hydronic Heating Efficient Natural Gas Boilers (NG)
Natural Gas Boilers for Hydronic Heating Systems. Efficient Gas Boilers in Cast Iron, Wall Hung, Condensing, Combination (Combi). Natural Gas Heating Boilers for all types of Hydronic Heat Applications such as Pex Floor Heating, Hydronic Radiators, Hydronic Baseboards or Fan Convectors. You can also connect up Indirect Hot Water Storage Tanks to Natural Gas Boilers and get efficient hot water (IE, what ever the efficiency of the boiler - that will be the efficiency of you tank minus heat losses).
With the increasing amount of Natural Gas and lower cost associated with Natural Gas Fired Boilers - more and more households are switching to Natural Gas over Propane, Electricity or Oil Fuel. Of course, if you don't have Natural Gas - then your best options will be Electric, Oil or Propane gas depending on the cost of these fuels in your area.
