Efficient heating

The heat loss of a home depends upon a number of factors including –

  • type of dwelling such as detached, semi-detached or attached or whether it is an apartment
  • number of stories
  • condition of the fabric such as doors and windows
  • level of insulation

Adding insulation
The average life time of a dwelling in the EU is now more than 100 years. Over the years the building standards have increased in all countries so that the older the dwelling, the poorer the insulation standard. Increasing the level of insulation to that closer to today’s standards will improve the fabric of the dwelling, extend its life and reduce any condensation that might be present. In this way, savings can be made in terms of energy, money and the environment. A grant may be available to insulate your home so it is worth checking with your local energy advice centre or utility.

Servicing
If it is more than two years since your heating system was checked, it is worth arranging a service visit to minimise your heating demand and save the environment. Servicing your system will also allow the service engineer to undertake a ‘health’ check to ensure your system is operating at optimum efficiency.

To ensure good heat transfer from your radiators, the neutrality of the central heating water (pH level) should also be checked at the same time. If this level is not neutral then corrosion will likely have occurred between the water and any metal parts such as the radiators which will result in the build up of deposits on the inside of your radiators. This deposit will reduce heat transfer, increase heating bills and reduce life of your central heating system. To prevent such corrosion occurring, an inhibitor and descaler (such as Vexo X-P010) should then be added.

Replacing heating system
If your system is more than 15 years old, it is worth asking the service engineer about the condition of the system, the availability of spare parts and the cost of replacing the existing system with a newer and more efficient heating system. As additional insulation may have been added since the existing boiler was installed, it is desirable to recalculate the heat loss so that the heating system can be correctly sized.
