Over the last 130 years Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing lasting heating solutions is seen in every boiler they make. The WTGO is a flexible durable oil-fired combi boil. In the WTGO Weil-McLain has taken their exceptional WGO design and added a tankless coil for water heating making the WTGO an inclusive heating solution. Efficient energy use is a high point of the WTGO’s design allowing you to make the most of your energy dollar. Weil-McLain knows the value of longevity that’s why they used cast-iron for WTGO boiler sections. Between the high efficiency durable construction and flexibility the WTGO excels both as a replacement combi boiler and as an addition to new construction.
