As the temperatures continue to fall, it’s important to separate fact from fiction and bust these common central heating myths once and for all. 

Energy experts at Warma have shared four of the most widespread misconceptions households need to know about.

1. Cranking heating to full blast is more efficient

This is one of the most common myths, and it’s a “big myth”. Overloading the heating system can lead to unnecessary strain and may cause the heating system to overcompensate for the sudden demand. 

This will only result in a sharp increase in energy usage and at the same time, “reduce your system’s lifespan”. 

Instead, it is best to maintain moderate and sensible settings to “keep your energy bills at bay”.

2. Closing does to unused rooms will save energy

This often practised myth is “completely flawed” as most central heating units are designed to distribute heat evenly throughout your home, so shutting the doors can disrupt the airflow and “lead to colder rooms and costly bills”. 

This can cause the system to overwork to distribute warmth to the cold areas, leading to higher bills overall. 

The experts explained: “Closing doors will not only result in uneven room temperatures but also increase the pressure on the ductwork, making your central heating system work more harder than necessary.”

3. You only need to check your central heating every couple of years

This could not be further from the truth as the central heating system plays a key role in keeping a house warm and, at the same time, protecting pipes and the water supply. 

The experts warned: “Like other electrical appliances, your central heating system will wear out over time and may develop faults and breakdowns that require maintenance, making it important to schedule regular inspections.

“Waiting for the system to develop an issue will only result in costly emergency repair bills.” It is recommended that you schedule a maintenance check at least once a year to “avoid major issues”.

4. Radiators don’t need bleeding

Radiators require regular maintenance, just like your central heating system, to keep them working properly

Trapped air inside the radiators or the pipes will result in reduced heat output, making your heating system “less efficient, and reducing warmth in your home”. 

The solution to this problem is simply known as bleeding the system. Bleeding is a “quick and easy” process that releases trapped air from the radiators and resumes “optimal performance”.
