Heating On, But House Still Cold? 5 Possible Causes

It's a common scenario that many homeowners face – the heating is on, but the house is still cold, and you're bundled up in blankets. Before you turn up the temperature, it might be worth investigating some common culprits. Here are five possible reasons your house isn’t as toasty as it should be, even with the heating on.

1. Inadequate insulation

The insulation in your home acts like a cosy blanket, keeping the warm air in and the cold air out. If your house isn't properly insulated, that lovely warm air your heating system is working so hard to make could be slipping right out – especially in key areas like the attic and walls.

Checking the quality and effectiveness of your home’s insulation is the first step to ensuring the heat stays where it should be – inside!

2. Draughty doors and windows

If you've ever sat near a draughty window in the middle of winter, you know it can feel like there’s an invisible ice breeze slipping through. Gaps in doors and windows let warm air escape and cold air enter. It might be time to weatherstrip your doors and windows or consider replacing them if they’re old and inefficient. This not only helps in keeping your home warm but also aids in reducing your energy bills.

3. Outdated or inefficient heating system

Your heating system is like the heart of your home during the colder months. If it's outdated or not working efficiently, it’s likely the reason the heat is on but the house is cold. It won’t pump the heat throughout your home effectively. Regular maintenance, such as annual check-ups by a professional, can keep your heating system running efficiently. If your boiler is older than 15 years, it might be time to think about a replacement.

4. Blocked or closed vents and radiators

It’s a small thing that can make a big difference. Make sure all vents and radiators are open and not blocked by furniture or curtains. Blocked vents can prevent the warm air from circulating freely in your rooms. It’s also a good idea to bleed your radiators to remove any trapped air that can cause cold spots and reduce their efficiency.

5. Thermostat issues

Sometimes, the issue could be as simple as a malfunctioning thermostat. If the thermostat is not calibrated correctly, your house will still be cold with the heat on. The heating system may not be signalled to start or might turn off before the house is adequately warm. Check to ensure it's working correctly and set at the right temperature. Consider upgrading to a programmable or smart thermostat for better control over your home’s heating.
