| Boilers and reducing fuel
bills |
| |
| Due to far reaching advances in heating technology,
today's boilers are more energy efficient than boilers previously
installed and now coming to the end of there normal working
life. Replacing a 15 year old boiler with a modern highly efficient
model, could save you over 20% on your existing fuel bills. |
| |
| Regular maintenance of the boiler |
| |
| Boilers should be checked at least once a year
and the filter on a warm air unit should be regularly cleaned. Check the
plumbers database for engineers that provide servicing or regular maintenance
contracts. |

Replace an older
boiler |
| |
| Older boilers are only about 50-60%
efficient and should be replaced by either a modern conventional model -
efficiency 70-80% - or a condensing boiler - about 90% efficient. Condensing
boilers cost more than a conventional boiler but savings in fuel bills will
give a payback period of 3-6 years. New 'high efficiency' gas boilers, for
example, those with thermal capacity heat exchangers, are more efficient
than standard new boilers and may be more suitable for small or medium sized
houses |
| |
| How to choose an efficient
boiler |
| |
| There is now a boiler database showing
the efficiency of gas and oil domestic boilers. Both current and obsolete
boilers are included and the database is regularly updated. The database
was developed on behalf of the government to help SAP assessors and is also
intended to help purchasers and specifiers to select efficient heating boilers
for domestic central heating system. |

Most boiler manufacturers publish the average
seasonal efficiency figures of their boilers, similar to the ratings you
see on electrical appliances such as fridges freezers and washing machines
etc. A simple guide to efficiency, has been created with SEDBUK efficiency
bands assigned to boilers on a 'A' to 'G' scale. The band is shown on the
database and may be used on product literature, the scheme is temporary
and it will be replaced when the European directive on boiler energy labeling
is introduced. |

| SEDBUK (Seasonal Efficiency of Domestic
Boilers in the UK) |
| |
| SEDBUK is the average annual in-use efficiency
applicable to a particular boiler. It should not be confused with other
output figures for efficiency that are sometimes quoted in the manufacturers
product literature.
The Boiler Efficiency Data File is published as part of the
DETR's Boiler Efficiency Database scheme. It holds data on
domestic boilers, gas and oil fired only, current and obsolete,
for the purposes of carrying out SAP energy ratings. SEDBUK
(Seasonal Efficiency of Domestic Boilers in the UK) is
a new method for calculating the seasonal efficiency of central
heating boilers, developed and agreed with boiler manufacturers.
Its purpose is to identify differences in efficiency between
different boilers in such a way that they are recognised and
treated fairly in the SAP. The new method uses efficiency
test results already obtained by manufacturers to demonstrate
compliance with the European Boiler Efficiency Directive,
so does not require any additional testing to be carried out.
