7 ways to prevent heat loss in your home

Think you’re losing heat at home? These tips can help you to prevent heat loss, and save money on your heating bills as a result!

It can be hard to know if you’re losing heat at home, especially if you have no obvious draughts. But heat loss is pretty common, and it could be costing you on your energy bills. Here’s what you can do to prevent heat loss and save money on your heating bills:

  1. Close off any draughts around windows and doors
  2. Keep your curtains closed at night to keep the heat in
  3. Insert a layer of radiator foil on the wall behind your radiators
  4. Keep internal doors closed so heat can’t escape
  5. Insulate your water tank
  6. If you don’t light your fire, use a chimney balloon
  7. See if you’re eligible for energy-efficiency grants

1. Close off any draughts around windows and doors

The majority of draughts come in through the gaps around the windows and doors. Attaching brush strips to the end of your door will really help and, for windows, you can use silicone to seal off draughts around the frame.

2. Keep your curtains closed at night to keep the heat in

Much of the heat loss from a house occurs through the windows, especially if they are single glazed. So keep your curtains closed at night, even in empty rooms, and - if possible - ensure that the curtains don’t hang over the radiators as that will just funnel all your heat out the window.

3. Insert a layer of radiator foil on the wall behind your radiators

If you have wall-mounted radiators, inserting a layer of radiator foil on the wall behind them will ensure that none of the heat is absorbed into the wall. Radiator foil costs around €20, so there is an outlay, but you should notice the difference on your bills.

4. Keep internal doors closed so heat can’t escape

Most people have one or two rooms in their house that they spend the vast majority of their time in. If this sounds like you, make sure you close the doors into these rooms once you’re inside, to stop heat escaping. By doing this, you could also turn off radiators in the rooms that are not in use - thereby saving even more energy.

5. Insulate your water tank

This is one you may not notice, but you could be using the immersion for longer than necessary if your water tank is not insulated. Fit a lagging jacket and you’ll notice a huge difference.

6. If you don’t light your fire, use a chimney balloon

If you have an open fireplace but you never light the fire, consider fitting a chimney balloon. They cost around €25 each and not only do they eliminate heat loss through the chimney, they also stop cold air coming down into the room.

7. See if you’re eligible for energy-efficiency grants

Talk to your energy supplier or the Sustainable Energy Authority of Ireland (SEAI) about grants and financial help to install energy saving measures. Most of the heat in the home is lost through the roof and walls, so using a grant to install some wall or attic insulation could make a huge difference.
