Why throw your old furnace away, when you can recycle it and use it for years to come? We can turn your old, inefficient and potentially dangerous furnace into an integrated system that heats at up to 98% efficiency simply by connecting your high-efficiency Navien water heater to it using the innovative H2Air system from Navien. We will remove the burners, gas valve and combustion chamber from your furnace, rendering it safe and quiet, and install hot water heating coils that will produce space heat at the efficiency of the attached water heater. Your furnace then becomes a "fan and a box", and your new water heater does all the work to heat your home with no flue gases. This is also a very simple system that costs 1/3 the cost of an equivalent furnace to install.
