Vitodens 222f or green star combi

I usually only install Vitodens 100’s but I need a floor standing unit due to space. I’ve never installed a 222f and didn’t know if anyone has had any issues.

I have installed two of them. Both 130 MBTUs. Excellent boilers. Nice for "on-board" domestic hot water.
Intall and service "friendly."

Just make sure you ask for the correct connection set to go with the 222f. Inexperienced sales people may quote them without the connection kit, make sure you get that kit as part of your quote. I am quite partial to the 222f but they never caught on in my area. I have one that I am procrastinating on parting out/ scrapping that I used as a display for the past 5 years or so.

The two places I installed them MI and VT, I would say the same thing: "they didn't really catch on." So finding local contractors that will readily service them is a bit of a stretch. You MUST be 'conversant' with Viessmann's tech support protocol and their parts acquisition. And of course STUDY the manual to understand the "boiler logic.' It's a nice machine...all that said. Oh, and service them annually.

FWIW.... another option for a floor standing unit.

222F is an excellent boiler. Installed many of them with no issues.

We've installed three, all with no problems. However, there was one up in the wine country that was installed by another contractor that had issues with a frozen check valve in an unusual location that took days to find. V. technical support, as good as they are, had never seen the problem. Other than that, they have been flawless.

Make sure to check the condition of the boiler when they get delivered as the packaging is not the greatest and they can get manhandled.
