New Boiler Installation and Servicing

Your boiler is the heart of your house. Whether it is a gas boiler, oil, solid fuel or electric boiler, it must be reliable, efficient and safe to operate. A well-maintained and high quality boiler will serve for decades. Here are a few essential points to keep in mind.

Boiler Servicing

After fitting a new boiler it is crucial to identify all the factors that can affect its efficiency. You can find a boiler inspector, boiler cleaner or electric on an ad hoc basis, however best way to always keep the appliance in a good condition is to hire a local company that provides boiler maintenance services. A boiler man will then come regularly to conduct an annual performance and safety check as well as advise on any procedures your boiler might need. As a part of health and safety inspection, the following components must be regularly checked:

  • Air Elimination Devices
  • Back Flow Assembly Devices
  • Burners
  • Combustion fan
  • Flue ways and terminals
  • Gas pressure and heat input
  • Heat exchangers
  • Ignition systems
  • Low Water Cut Offs
  • Pressure Relief Valves
  • Seals (gas and water)
  • Secondary Aquastat
  • Ventilation provision
  • Visible pipework & controls

Backflow Testing

Most probably you boiler is connected to the city water supply via a device called backflow assembly. It is required to prevent contamination of domestic water systems by the stagnant water from the ground, from storage or from other sources. It is important to periodically test your back flow device as a sudden drop of water pressure occurred because of a water main burst or pipe freeze may result in your water being contaminated.

Boiler Efficiency Testing

It pays to regularly measure boiler combustion efficiency and make adjustments when necessary. Without proper maintenance boiler efficiency can drop to 50% or lower (see rate bands below)! Dirty fire side or water side of the heat exchanger or inadequate combustion air may cause a drop in combustion effectiveness. The combustion efficiency can be measured by trained maintenance staff or a qualified contractor and normally a special analyser is used to take the measurement. However, combustion efficiency is not same as overall boiler efficiency as there are other factors like heat losses that need to be taken into account. After boiler efficiency testing procedure the specialist will be able to give you advice on whether any further maintenance like burner adjustment, chemical boiler cleaning or enlarging air intakes is required. Remember to check your boiler at least once a year as boiler maintenance reduces the cost in the long run and prevents break downs.

SEDBUK - boiler efficiency rating

Sometimes you might want to consider installing a new boiler as it has a few important benefits. Boilers that are older than 10-15 years may not have energy saving controls and safety devices found on boilers of a newer generation. With an improved heating control you will also get an improved boiler efficiency and quieter boiler operation. The new boiler will probably also be smaller in size. If you opt for fitting a new boiler and you are located in the UK, you should know what SEDBUK is. This abbreviation stands for the Seasonal Efficiency of Domestic Boilers in the UK and it is a rating standard developed under the UK Government's energy efficiency best practice programme with the co-operation of major boiler manufacturers including Worcester Bosch Group, Vokera, Vaillant and others. When comparing boilers from various manufacturers, make sure to check their SEDBUK rate as a boiler of band D for example would mean that for every £1 spent on fuel, 18-22p would be lost and with only 72-82p being used to heat your house.

What type of boiler do you need? Combi Boiler provides heating and hot water directly from the boiler, which means no large cylinders or roof tanks required. Due to these great space-saving features, it is an increasingly popular choice in UK homes. A combi boiler provides both water heating and central heating and can fit in a kitchen cabinet. It is a perfect solution if you live in a flat or bungalow, or if you want to use your house loft space for a room conversion or even if you don’t want to wait for the system to heat up to get hot water available on tap.

Regular boiler or as it is also known conventional boiler on the other hand heats your central heating system and provides hot water for your cylinder. You may decide to go for that option if you are replacing an existing regular boiler system, if your property has more than 2 bathrooms, or if the main water pressure is low.
