Sizing an Indirect Hot Water
Just finished up installing a Buderus G124X/32 with the Logamatic (dId it myself) and my old standalone hot water 50 gallons is 10 years old. I'm thinking of going indirect for the effiency but I'm not having any issues with regards to running out of hot water at the moment even though I have 5 adults in my house (3 of the will be moving out within the next few months). My question is if I purchase the Buderus St-150 40 gallons size will I still have enough hot water just for two people?
3 zone loops each zone covering 1000sf of living space for each floor; but we no longer use the third floor, so I'll be heating just the two floors.
