(based on running hours, calculated using FTC-published average energy costs, Jan.
2009; $1.21 per therm) The cost of fuel in some areas of the country has increased by
almost 40% in just one year. The highly efficient modulating output of the Mod Con
VWH will provide a maximum payback on fuel savings. As the charts below illustrate,
savings can result in a payback period in less than three years when compared to the
conventional technology of other Hot Water Supply Boilers. The Mod Con VWH could
save you as much as 50% on your present fuel bills.
