How do I get better efficiency from my boiler or cylinder?

There are a number of ways that you can help to get better energy efficiency, those being:

  1. Insulation – if your house is not insulated correctly then you will be losing heat through the roof, floors walls or windows which means that your boiler will need to work a lot harder.
  2. Radiator size – the bigger the area of the radiator the quicker it will heat a room. The bigger the room, the bigger the radiator needed.
  3. Smart controls – this technology is more convenient and gives you more visibility and control of your energy usage so that you can reduce waste.
  4. Annual servicing – this ensures that you can catch problems early on before they develop into bigger problems or cause long term damage.
