Home heating is an essential aspect of comfort during the chilly UK winters. Among the myriad of options available, electric storage heaters stand out for their unique functionality and efficiency. If you’ve ever wondered, “How do storage heaters work?” you’re not alone.

Understanding how these heaters operate can make a significant difference in your energy bills and home comfort. They harness off-peak electricity, offering an economical solution that can reduce costs and provide warmth when you need it most.

Let’s delve deeper into the mechanics of these heaters and discover if they are the right fit for your home.

How do storage heaters work?

Electric storage heaters are specifically engineered heating systems that store thermal energy during off-peak hours, particularly under the Economy 7 tariff in the UK. Subsequently, they slowly disperse this stored warmth throughout the day.

This feature has made them a preferred option for individuals seeking to effectively minimise heating expenses while maintaining a cosy and inviting home environment. But how do storage heaters work? Let’s break it down.

The heating process

• Charging phase: During the off-peak hours, electricity flows into the heating elements within the storage heater. These elements heat up specially made ceramic or clay bricks that act as effective thermal mass, storing heat for later use.

• Heat retention: The bricks retain heat for many hours, allowing the heater to continuously radiate warmth even after the electricity supply has stopped.

• Releasing heat: As the day progresses, the heater gradually releases the stored heat into the room. The output control dial allows you to adjust the amount of heat released, tailoring the comfort level to your needs.

Control mechanism

• Input dial: This knob controls how much heat the heater absorbs during the night. A higher setting means more heat is stored, which is ideal for particularly cold nights.

• Output dial: This knob adjusts how much heat is released during the day. If you find the room too warm or too cool, tweak this setting to achieve optimal comfort.

• Boost setting: Need extra warmth? The boost setting provides extra heat on demand, perfect for unexpected guests or chilly afternoons.

Safety and efficiency

Modern heaters often come equipped with a damper valve and a thermostat. The damper valve helps regulate airflow, while the thermostat ensures that the room temperature remains steady, enhancing energy efficiency.
