I just installed a big max in my garage this weekend. I don't have easy access to gas so I converted it to propane. I'm not super impressed with the heat coming out of it but I do need to adjust the gas pressures as it's different for propane. I'll give a better review later this week when I finish it.
Here is a floor heat boiler system I installed last week. This has 30 runs in it.
