Answer:

SEDBUK stands for ‘Seasonal Efficiency of a Domestic Boiler in the UK’, and is designed to provide a fair comparison of the energy performance of different boilers.

SEDBUK 2005 ratings are shown on labels as A-G, similar to those found on refrigerators and washing machines, where A is 90% or more efficient.

This method has been superseded SEDBUK 2009, where the boiler efficiency is shown as a percentage.

Answer:

Depending on heat output, combination boilers can only supply a one tap at a time. Turning on additional taps will reduce the flow of hot water.

If the water is not hot enough you may have to reduce the flow (by turning the tap down) to increase the temperature.

This may be necessary especially in winter when the water supply to the boiler is colder.

Answer:

Most standard shower fittings will be compatible with a combi boiler.

If you have a multijet shower the water demand may exceed that of a combi boiler and you should check the manufacturer’s installation instructions.

You may be better with a system boiler and hot water storage cylinder.

We recommend that you always seek the advice of a Gas Safe registered installer.
