Condensing boilers/ VSI or Mixing valves? — Heating

However, on the boiler side there is a BIG difference. On a condensing boiler if the return water temps are not below the dewpoint (approx. 136 degrees F. for Nat. Gas) then there is no condensation on the fire side. This means that you have sold someone a higher priced condensing boiler that only sees about 85-87% efficiencies.
