Completed in early April 2009, this customer’s house, on the Sanderstead/Purley borders (Surrey, UK) had an aged Potterton boiler removed and changed for a new wall hung Worcester Bosch 24Ri.

Who left that van there?

Who left that van there?

The new boiler was a third of the size and weight of the old unit, but had exactly the same power output.

The old cast iron unit had been very reliable, but extremely wasteful of gas.  Old floorstanding cast iron units rarely give an efficiency of greater than 65%. 

A new high efficiency boiler will achieve around 90% efficiency.

In other words, comparing the old boiler to the new one, for every £1.00 you spend on gas, 25p is immediately lost, forever.

And of course, if you are using less gas, your household emissions will lower, and there will be considerably more gas left for everyone else.

The only losers are the people selling you the energy in the first place…….. 

Getting back to our installation picture file, the old boiler had an enormous balanced flue which we painstakingly bricked up to match the existing….. if you look closely you may be able to see.
