FAQs Central Heating

Carbon Monoxide Kills

Here we answer some of your FAQs (Frequently Asked Questions) relating to central heating, types of boiler installations and the dangers of not servicing gas appliances.

See the video on gas safety below.

Combi boilers (also known as combination boilers) are the UK's most popular type of boiler for gas central heating and domestic hot water.

This is mainly due to their size as they are often smaller than other types of boiler and do not require a tank or hot water cylinder. The ‘instant’ hot water combi boilers produce hot water directly from the mains which makes them very fast and very efficient particularly for smaller homes, which need constant hot water.

If the property where you are looking to install a new boiler has a number of bathrooms/en suites, a combi boiler may not give the best delivery of hot water – it may be more advantageous to fit an open vent or system boiler, both of which are able to supply hot water quickly to several outlets at the same time. Baxter Heating offers a wide range of combination boilers to suit all types of properties and homeowner requirements.

Combination boilers are rated from A to D.

If your boiler is rated as C or D, you are literally burning money. Find out how much an energy efficient boiler could save you.

If you are experiencing any of the signs below with your boiler, you should contact a Baxter Heating engineer for an assessment – this may result in having boiler maintenance.

  • A reduction in the overall heat

  • Poor circulation
  • Excessive noise

  • Increases in your bills
  • Dirty water in the system

Carbon monoxide is colourless, odourless and tasteless, so the easiest way to detect it is by using a good quality audible carbon monoxide alarm. For you and your family's safety, it is advisable to fit a carbon monoxide alarm in each room in your home that has a gas appliance.

The Gas Safe Register recommends the use of an audible carbon monoxide alarm rather than one that changes colour when carbon monoxide is present.  It is important that it will alert you straight away or wake you up if you are asleep. The alarm should be marked with British Standard EN 50291, and a British or European approval mark such as the Kitemark.  It is also advisable to use carbon monoxide alarms that have a battery life of five years.

Fitting a carbon monoxide alarm is not a substitute for having your appliances regularly serviced.  Smoke alarms do not detect carbon monoxide. Don't forget to take a portable audible carbon monoxide alarm on holiday with you. Protecting the family when away is often overlooked in the rush to pack the family suitcases.
