First time order of boiler / burner unit & am SUPER happy!

I love Supplyhouse.com they are so easy to order from, everything came as it should & the boiler & burner went together very easy. It was pretty much plug and play. I hate dealing with most of the people at the local supply houses, especially when you have to pay an extra 25% more for their nonesense . The Weil Mclain WGO-3 & GO-3 Beckett burner I ordered replaced the old 25 y/o W/M blue series unit we had at one of our rentals. We ordered the outside temperature sensor too. It's amazing how far the electronics for efficiency have come. I'm hoping this new boiler system will save the tenants money with their heating, a happy tenant is one who stays longer and feathers the Landlord's nest that much more :)

Concerned about noise

Just bought a WTGO-3 and had installed a couple of days ago. It is louder then the old model it replaced. Is there anything that can be done to reduce noise? I paid for professional service to install and set up to avoid installation problems. Any suggestions?

Amazing product

Great boiler, especially for the price. Has no issues, hooked right up to the old piping. Me being a DIY guy thought it was going to take a day or 2 to install, minus my time for running around for things I forgot it took about 3-4hrs to take out the old and install the new. It's so quiet and barely runs compared to the old one I had.

Best Brand boiler out there!

Plumber recommended b/c it lasts longer. Arrived off truck with a small dent, spoke with customer service and they offered a little credit, made me feel better. Had it installed seems to work like a dream, will get better use out of it in the cold weather.

Right price, prompt delivery, excellent customer service

I ordered this furnace, and it's recommended burner assembly on a Monday afternoon. My order was in my basement, ready for install by Thursday after. Everything was spot on, well packaged, and at a price that comfortably beat all my local supply houses.

I would buy again if ever needed.

It is a little louder than I expected, but seems to work very well. Company was great to work with. First one delivered was damaged, but Supplyhouse replaced it expediently.

Pleased

Bought WGO3 boiler from Supplyhouse to replace weil McLain boiler I installed in our century home 1977. Delivery was quick & no problems. Its been operating without problems for 2 months now. Very pleased. Much improved over old unit. Smart control unit adjusts temp according to demand plus it does not fire the burner if boiler temp is already adequate for demand. Burner now has startup and shutdown blower purge cycle to start draft and purge exhaust so you do not smell any combustion fumes. Nozzle maintenance is easier with access door and coil spring loaded igniter contacts.

Q: What is the difference between WTGO series 2 and 3?

Asked by Martin 14 years ago

Verified Author and ReplyVerified Reply- PexSupply Staff

The difference between series 2 and 3 is a change in the cast iron design to reduce draft loss through the heat exchanger. Cast iron sections are still interchangeable between series 2 and 3.
