Energy specialists are warning homeowners that a prevalent heating practice may actually lead to increased energy consumption and higher bills. As temperatures drop, many property owners are seeking cost-effective solutions to keep their homes warm. However, a common belief that heating systems should be run in short, frequent intervals might be backfiring.
Experts from Grant Store have highlighted that modern heating systems operate most efficiently when maintaining a consistent temperature rather than being turned on and off multiple times throughout the day. A spokesperson from Grant Store explained that when heating systems are activated for brief periods, they need to work harder each time to reheat the property, ultimately consuming more energy than if a steady, moderate temperature were maintained.
The start-up phase of a boiler or heat pump requires additional power to reach the desired temperature, using considerably more energy than continuous operation. Furthermore, frequent short heating cycles can not only waste energy but also increase wear on system components, leading to decreased reliability and higher maintenance costs over time.
Grant Store’s experts elaborated that allowing a home to become excessively cold between heating cycles can also hinder system performance. When the house loses too much heat, the heating system must expend more effort and time to restore comfort levels. In contrast, maintaining a stable indoor temperature typically requires less energy than repeatedly heating an entire house from a cold state.
To alleviate these issues, experts recommend setting thermostats to keep a pleasant, constant temperature during times of occupancy. They advise using timers or smart thermostats to reduce heating when individuals are asleep or away, but caution against letting the interior cool down completely. A steady heating approach, as opposed to the “little and often” technique, is far more energy efficient.
Furthermore, proper insulation and draught-proofing are vital for optimizing energy efficiency. A well-insulated home can retain heat for extended periods, allowing inhabitants to utilize heating systems less frequently while remaining warm. Experts noted that sealing gaps around windows, doors, and floors can significantly reduce the need for heating.
The Grant Store team concluded that while frequent bursts of heating may appear economical, they often result in higher energy bills over time. They emphasized that modern heating systems are designed to perform best when allowed to run efficiently rather than undergoing constant restarts. Adopting a consistent heating strategy, paired with adequate insulation, can help households maintain comfort and reduce unnecessary energy waste.
The NHS also advises that maintaining a minimum home temperature of 18 degrees Celsius is essential for health and comfort. For those with smart meters, tracking real-time heating costs can provide invaluable insights into energy usage.
