Viessmann 100, 200, or Bosch?
Were replacing a 7 year old boiler nightmare, (HTP Munchkin MC-120 which is 120000 btu ). Our requirements are 1450 sq-ft house with air handler, indirect water heater, and 1000 sq-ft attached garage with floor heat. The present munchkin is installed in the crawl space with a space from cement cap to the floor above of 68 inches, this is between the floor joyces that are about 24 inches apart.. My question is how much room is required for a Bosch, and for a Viessmann. and is the Viessmann 100 capable of servicing my 3 heating requirements or do I need a Viessmann200. I will also add that my previous plumber 7 years ago added some black pipe to make a circle with a pump, a air handler that also has another pump, floor heat with another pump, the garage floor heat also has a mixing valve and another pump, indirect water heater with another water pump, with relay switches and water heater had priority. So before I start to contact plumbers to try and get an estimate if any will even commit to redo's now a days, WHAT IS THE BEST OPTION between these 3 boilers, or who makes the best?
