Weil Mclien GV90

[Firebrick43]

Does anyone have experience with a weil Mclain gv90 ci boiler?

I really need a boiler with pvc intake/exhaust. Originally looking at mod cons but in researching them the high maintenance al low life doesn't appeal to me for the small efficiency gain.

They always had a decent reputation ... have you looked at the Buderus traditional sealed combustion CI boilers .. they are a great boiler and a very good value.

Is this a retrofit .... ?

Buderus is all I use .... would not be going with a mod con in my new build unless I had to ... no space and propane. I still own my first project w/ Buderus -- typical CI w/ chimney 1993

I installed a Weil-McLain boiler in 1988 in my house in Chicago. It was a GVxx and I also used the boiler to heat the domestic hot water. Worked fine. I had trouble with the vent piping as it was the concentric pipe in a pipe the for intake and exhaust. In the winter the wind would blow the exhaust back into the intake and the cold air would freeze the condensate. If you have the pipes separate that wouldn't be a problem. I moved out of there in 2006 and the system was working fine. I put one igniter for repair.

New build. Plenty of space but it's going to be very difficult to do a traditional chimney as the floor between the basement/living level is a composite Stella concrete slab. It has 3.25" hole for PVC pipe cast in for intake/exhaust but to add a real chimney is going to be very difficult. Buderus does appear to offer a CI boiler with a recuperator like the gv90. There SSB has a stainless water tube boiler?? It's appears to be a modcon packaged in a floor cabinet???

Thank you. I was looking at the concentric vent (more for looks) but I am at the point of build that I can seperate them with a significant distance and would be cheaper anyway. I am existing on the gable end of the house.

The GA was the CI Buderus I was thinking .... typical boiler -- it uses metal 3" pipe and can also use concentric.

The SS unit must be new .. wonder if it's a Bosch setup? I don't see a picture of the internals -- must be a low mass boiler.

Most of my projects are restorations and typically have some form of hydronic heat -- being in the mid atlantic we have a longish heating season. I really like old school high mass boilers with any type of radiators -- CI or more modern panel (I don't like or ever use copper baseboard). Set them up with outdoor reset -- work great. They also work great with radiant ... simple systems with little to go wrong. Buderus boilers are able to take the cold return water that kills others.

You have to follow the concentric direction to the letter -- most don't want the vent high up on a gable side.
