I am looking at a condensing boiler (propane) for my house to heat
domestic how water and radiant in the floor. I will need about
50000-75000 BTU.

My plumber is pushing a Viessmann model, which is extremely costly. A
Buderus boiler is still costly but not as bad. The vent kit is also
more expensive for Viessmann,which requires its own venting pipes,
compared to Buderus which uses regular Sch 40 PVC.

Can anyone offer any ideas on this comparison?

Thanks, mh

What will you do when that runs out?
