Furnace Retrofit

ThorpeWood took note of a design inefficiency in our dual-fuel furnaces (wood/oil), and retrofitted them with hot water coils to be more energy efficient. By redirecting hot water circulation to include a loop through the heating ducts, we have taken advantage of a heat source that was present but underutilized. By this simple mechanical retrofit, we can heat ThorpeWood each year with less than half the oil we used in previous years, and pay for the cost of the retrofit in oil savings within approximately five years.
