I'm no expert but I have a lot of interaction with homeowners (and I am on the internet which, on second thought, does make me an expert) and Water Furnace seems to be one of the brands that has a solid track record, especially with the newer generations of units. WF is headquartered right here in good ol' southern Canada aka Fort Wayne.On my 2nd geothermal water furnace. Love the low electric bill, the almost free hot water, and almost no need for maintenance. Been good to me.
My observation is that a lot of the systems made in the ~80s/90s-ish era never saw the expected longevity though the newer units seem to be meeting expectations.
