How It Works

The electric boiler is installed alongside (in parallel) the existing natural gas-fired boiler(s). You then compare gas prices and electric rates for a given timeframe and produce steam using whichever boiler provides the lowest cost steam. An automated controller can be installed to perform this comparison and signal the appropriate boiler to operate. It is as simple as that! When the electric energy price controller signals to make steam, the electric boiler is turned on and runs 5 psi higher than the gas boiler(s). When electricity costs are high, the opposite occurs.
