For many households, heating controls are something we rarely think about, until energy bills rise or the home starts feeling uncomfortable. But understanding how your heating controls work could help you save money, improve comfort, and make your heating system far more efficient.

 

Why does my heating system need temperature controls? 

Your heating system is designed to cope with the coldest winter days. That means for much of the year it is capable of producing far more heat than your home actually needs. 

Temperature controls help manage this by ensuring your home reaches the temperature you want, without wasting energy overheating rooms unnecessarily. 

Without effective controls, your heating system can continue producing heat even after rooms are already warm enough, increasing running costs and reducing comfort. 

Can’t I just turn the boiler on and off myself? 

Many homeowners still manage heating this way, but it’s not usually the most efficient approach. 

Heating systems without proper controls often warm rooms unevenly. For example, bedrooms may become overheated before living spaces feel comfortable. This means more energy is used than necessary. 

There’s another important factor too: boilers are typically least efficient during the first hour of operation. Running your heating for slightly longer periods with the right controls in place can often use less energy overall while maintaining a more consistent level of comfort. 

In other words, better controls can help you get more warmth for your money. 

Should I turn the thermostat up when it gets colder outside? 

No - and this is one of the most common misconceptions about heating controls. 

Your room thermostat is designed to maintain the temperature you set, regardless of the weather outside. If temperatures drop outdoors, the heating system will automatically work harder to maintain the same indoor temperature. 

Turning the thermostat higher won’t heat the house faster; it will simply make the home warmer than intended. 

Is it cheaper to leave heating on low all day? 

This is a question many households ask, especially during winter. 

Some people believe it is more efficient to leave heating running continuously at a low temperature rather than turning it off when not needed. The theory is that reheating the building structure uses more energy. 

In practice, most homes will use less energy by turning heating off when it is not required. However, this can vary depending on the type and insulation levels of the property. 

Testing carried out at the Salford University Energy House found that maintaining a background temperature of 16°C during non-heated periods increased running costs by around 3% compared to turning the heating off completely. 

A programmable room thermostat can help strike the right balance by automatically lowering temperatures when you are asleep or away from home. 

Why heating controls matter more than ever 

With energy prices continuing to be a concern for households, getting the most from existing heating systems has never been more important. 

Simple changes to the way heating is controlled can improve comfort, reduce wasted energy, and lower fuel bills, often without the need for major upgrades or disruption.
