Heating Tips

Heaters:

  • When buying heaters, make sure that they are the right size for the rooms they are to heat, and that they have thermostatic controls.
  • Remember that electric heaters other than storage heaters consume electricity at the most expensive charge rate.
  • Use a space or portable heater instead of the central heater, if only one room needs heating.
  • Choose heaters with thermostat controls and timers.


Central Heating:

  • Turn off the heating overnight and when you are out during the day.
  • Turn off the heating if you are going to be out of the house for more than a day.
  • Proper control and regular maintenance of your heating system can reduce fuel consumption by 10-20%
  • If you have gas heating, turn-off pilot lights during the warmer months.
    Heat bedroom areas to less than 18oC
  • 20o C is an ideal room temperature. Turning down thermosats by 1oC can reduce annual space heating energy consumption by 10% with an equivalent reduction in greenhouse gas emissions.

 

Heat Loss:

  • Open fires are wasteful of energy with more than 70% of the energy going up the chimney.
  • If the radiator is mounted below a window, a projecting window-board or shelf above the radiator will direct warm air into the room, reducing heat loss through the window.
  • Close doors to separate heated from unheated areas of your home, and minimise the area you are heating.

 

Hot Water Heating:

  • Use the timer on immersion heaters. This should supply you with enough hot water as and when you need.
  • Heating hot water account for 64% of energy consumption in the home: you should be thrifty in its use.
  • 90% of the energy consumption of washing machines goes on heating the water. Wash clothes whenever possible in cold or cool water.

 

Insulation Tips

  • Insulate your attic well and save up to 20% on your home heating bill. If your attic insulation is currently less than 200 mm, then you should add further layers. There are a variety of suitable materials including mineral wool, rock wool, sheeps wool, polystyrene, cellulose fibre and multi-layered foil.
  • Wall insulation can be increased in a number of ways. The pay-back period is dependent on a number of factors including type, thickness and quality of existing insulation. The most popular types of insulation systems are, (i) insulated dry lining, (ii) blown mineral or cellulose fibre or polystyrene beads into the cavity, or (iii) rigid external insulation with render or brick finish. Specialist advice should be sought in all cases.
  • Choose double glazed units when replacing windows. Much of the heat loss from a house occurs through the windows particularly if they are single glazed. Significant energy savings can be achieved if double glazing has Argon fill and low-emissivity glass.
  • If replacing the hot water cylinder, a cylinder with factory applied insulation should be considered. Such insulation is more effective at retaining heat than a lagging jacket, is less easily damaged and cannot be pulled out of place.
  • A lagging jacket on your hot water cylinder will keep water hotter for longer and pay for itself in 2-3 months.
  • Keep curtains closed at night and ensure that the curtains don’t hang over the radiators.
  • A reflective foil, backed by insulation if space permits should be fixed behind radiators mounted on external walls.
