Replacing My Boiler | Energy Saving Trust

A condensing boiler has a larger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient. Sometimes the flue gases get so cool that the water vapour in the gas condenses out, hence the name, and even more energy is recovered from the condensing vapour. Things to consider. If it is time to change your

What is a low loss header? - Hamworthy Heating

The size of the low loss header relates to the output of the boiler and the system load, design and chosen temperature differential. The header should be sized so that the pressure loss at full flow is small. All secondary circuit flows and the flow from the boilers should normally be at the top, or one end of the header. All secondary circuit
