What temperature should a condensing boiler be set

A condensing boiler is one of the most efficient types of boiler. This is because it is able to recover virtually all the heat from the flue gases and use this to heat your home. For the boiler to work at its most efficient, the heat exchanger needs to be equal to or below the dew point temperature.

What outlet temperature is ideal in a residential boiler

Many modern systems are able to vary the outlet temperature of the boiler by modulating the firing rate so as to match the heat load of the structure to the ability of the radiation to satisfy the load. Most commonly this is done with "outdoor reset". Other systems -- where the boiler can't modulate -- instead modulate the water circulating in
