Due to far reaching advances in heating technology, today’s heating oil boilers are more energy efficient than those boilers previously installed and now coming to the end of there normal working life. Replacing a 15 year old heating oil boiler with a modern highly efficient model, could save you over 20% on your existing fuel bills.
Regular maintenance of the heating oil boiler
Boilers should be checked at least once a year and the filter on a warm air unit should be regularly cleaned. Please ensure that engineers that provide servicing or regular maintenance work contracts are registered with OFTEC.
Replace an older heating oil 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 heating oil 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 labelling is introduced.
