Winter Heating Mistakes to Avoid
Winter heating mistakes homeowners often make and how to avoid them

When winter arrives, every household wants a warm and comfortable home. The colder months can also bring sudden boiler problems, frozen pipes and higher energy bills. Many of these issues happen because of small, easy to prevent mistakes that most people do not realise they are making. With a few simple habits, you can keep your winter heating system running smoothly all season.
Below are some of the most common winter heating mistakes and how to avoid them. These friendly, practical tips will help keep your home warm, safe and efficient throughout winter.
Turning the heating fully off during cold weather
Switching your heating off completely when you leave the house or overnight may seem like a money saving idea, but it often has the opposite effect. When your home gets very cold, your boiler has to work much harder to warm it back up. This uses more energy and increases the risk of frozen pipework.
A better approach is to:
- Keep a low background temperature set on your thermostat
- Use smart controls to reduce the temperature rather than turning the heating off
- Aim to keep the home above roughly 12 to 14 degrees to protect your boiler and pipes
Blocking radiators with furniture
Placing sofas, beds or large cabinets in front of radiators is very common, but it traps heat, reduces airflow and makes your boiler work harder. This often leads to uneven heating and higher energy bills.
Blocked radiators can cause:
- Cold rooms even when the heating is on
- Slower heat up times
- Inefficient system performance
Try to leave a small gap around radiators and avoid covering them with clothes or drying racks, especially during winter.
Ignoring low boiler pressure
Boiler pressure naturally drops more often during winter because the system is working harder. Many homeowners do not notice the pressure gauge until the heating stops or radiators feel lukewarm.
Signs your boiler pressure might be low include:
- Radiators taking a long time to heat up
- Rooms feeling cooler than usual
- The boiler turning off unexpectedly
Check your pressure gauge regularly throughout winter. If the pressure keeps dropping, there may be a leak or a faulty valve that needs professional attention.
Forgetting to bleed radiators
Trapped air inside radiators is a common winter issue. It creates cold spots and stops heat circulating properly. Many people do not realise there is a problem until their home feels colder than usual.
Bleeding your radiators helps prevent:
- Gurgling noises coming from the system
- Uneven heating in different rooms
- Cold patches on radiators
If bleeding does not fix the issue, your system may have sludge buildup. In that case, a professional flush can help restore efficiency.
Using the thermostat incorrectly
Thermostat habits play a big part in home comfort during winter. Constantly changing the temperature wastes energy and does not heat the home faster.
To get the best results:
- Choose a comfortable temperature and keep it steady
- Make sure the thermostat is not placed in sunlight, near draughts or close to heat sources
- Consider using a smart thermostat for improved control
Skipping annual servicing
Winter is the worst time for a boiler breakdown, yet many households delay their annual service. A routine service keeps your boiler safe and improves efficiency, lowering the risk of a winter failure.
Annual servicing helps by:
- Identifying small problems before they turn into costly repairs
- Improving energy efficiency
- Keeping the manufacturer warranty valid
Neglecting condensate pipe protection
During cold spells, an external condensate pipe can freeze and block. When this happens, the boiler shuts down completely, which is a very common winter problem.
To reduce the risk:
- Ensure the pipe is properly insulated
- Ask an engineer about increasing the pipe diameter if freezing happens regularly
- Thaw a frozen pipe with warm water, never boiling water
Final thoughts
Winter places extra pressure on your heating system, but avoiding these common mistakes can make a big difference. With a few simple checks and good habits, you can enjoy a warm, reliable and efficient home throughout the coldest months. If you ever have concerns about your boiler or winter heating system, contacting a qualified engineer early can save time, stress and money.
