    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 GV90+ is a testament to their dedication to durability. A steel base and jacket are combined with cast-iron sections to make one of the most rugged high efficiency boilers in the marketplace. Condensing technology allows the GV90+ to capture gases expelled by traditional boilers and reuse the heat that these gases contain, saving you energy and expense. Getting your GV90+ up and running is simple; the boiler control features snap in connections and venting can be achieved through a direct vent, direct exhaust, or concentric vent system. The GV90+ is a boiler that will save you money for years into the future, the boiler's high efficiency and durability see to that.
  • Dual Heat Exchangers
  • A cast-iron primary exchanger provides reliable heat and peace of mind with its tremendous durability. The secondary exchanger is made from stainless steel to resist the corroding effect of condensation.
  • Multi-Pass Efficiency
  • The GV90+ features multi-pass designs for both heat exchangers. A five pass primary exchanger and two pass secondary exchanger improve the heat transfer surface area of the boiler, improving system efficiency and comfort.
  • Dual Circulators
  • The GV90+ includes a bypass circulator and system circulator. Including two circulators allows the GV90+ to accept low temperature return water that would damage other boilers, expanding the possible applications for the boiler right out of the box.
  • Extra Wide Waterways
  • The design of the GV90+ includes extra wide waterways. These channels are a blessing for older systems where debris may be present. Wider waterways improve flow within the boiler and prevent buildup which can limit efficiency.

Product Questions Answered by Bob, the Heating Product Expert
What is the reason for a "12" max" connecting pipes between the output and input of a boiler? I have a multi-zone system with one circulator on the return line to the boiler. Does the internal circulator use this pipe to heat up the return water?

Will the Weil-McLaine GV90+ convert to propane? Is the adapter included for the switch from NG to propane?
