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.
What are the different types of storage heaters?
Now you know how do electrical storage heaters work, but what type of storage heater is suitable for your home? There are several types, each designed for different needs and preferences, so finding the right one is crucial.
So, let’s explore the primary categories of electric storage heaters available in the UK:
Manual night storage heaters
Manual night storage heaters are the traditional option and are commonly found in many UK homes. These heaters charge overnight to utilise off-peak tariffs, have few manual control options, and offer limited functions for adjusting warmth needs.
High heat retention storage heaters
High heat retention storage heaters are designed with advanced materials, such as ceramic and clay bricks, to maximise heat retention. These heaters are built to store more heat and release it gradually throughout the day.
They are especially effective in homes where maintaining a steady warmth is a priority, reducing the need for frequent recharging.
Fan-assisted storage heaters
Fan-assisted storage heaters incorporate a fan to distribute heat more evenly across the room. The fan helps eliminate cold spots, ensuring consistent warmth throughout your home. These heaters are particularly effective in larger spaces to ensure quick and even heating.
Combination storage heaters
These ingenious electric room heaters combine the benefits of storage heating with a convection heating element. The built-in convection heater provides immediate warmth, making them perfect for those cold morning hours when you need heat fast.
Smart storage heaters
Smart storage heaters represent a modern solution in electric heating technology. With smart features, you can manage heating schedules from your smartphone or tablet. They often also come with programmable thermostats.
Many smart models learn your heating patterns, automatically adjusting their settings to maximise comfort while minimising energy costs.
Pros and Cons of storage heaters
Knowing how do storage heaters work and their types is not enough to make an informed decision. Before making a decision, take into account these pros and cons:
Pros:
- Cost-effective heating: Storage heaters utilise the Economy 7 tariff that can help homeowners significantly lower their electricity bills.
- Stable temperature: Most storage heaters, especially modern ones, excel at maintaining consistent warmth throughout the day.
- Minimal maintenance: Generally, storage heaters require less upkeep compared to traditional heating systems.
- Electric-only solution: For homes without gas connections, these heaters provide reliable heat using just electricity.
- Flexible placement: Their adaptability allows for customisable heating solutions, ensuring you can place them where they are most effective in your home.
Cons:
- Initial investment: The upfront cost for purchasing and installing electric storage heaters can be a little higher than that of traditional electric radiators.
- Delayed Warmth: Due to their storage nature, there may be a delay in heat availability, particularly for the older, less modern storage heaters.
- Manual control limitations: For manual night storage heaters, the need for manual adjustments may not suit every homeowner’s lifestyle.
- Space requirements: Storage heaters can be bulkier than alternative heating options, which could be a consideration for smaller homes.
Tips for maximising the performance of storage heaters
After learning how do storage heaters work and all the necessary information, you might choose to install a storage heater in your home. But how can you maximise performance and minimise energy costs?
Let’s give you some effective tips you can use to boost efficiency:
- To kick things off, it’s crucial to grasp the ins and outs of setting your heating schedules. Most storage heaters operate best when charging overnight during off-peak hours, particularly if you’re on the Economy 7 tariff.
- Take a moment to map out your daily routine and tailor your heating settings accordingly. Ensure your heaters are fully charged during the night to meet the demands of the day ahead.
- Adjust the input dial based on the expected temperature. On chillier evenings, crank up the input to store ample heat.
- During the day, tweak the output setting to release heat as needed. Remember to dial it down on milder days to avoid overheating.
- Exercise caution when using the boost function, as it can spike energy costs if overused. Reserve it for when you truly need that quick heat fix.
- Keep an eye out for wear and tear, and ensure that all heating elements are functioning properly if not take assistance from a storage heater repair expert.
- Ensure proper insulation plays a pivotal role. Inspect windows and doors for draughts, and seal them with weather stripping or draught excluders to prevent heat loss.
- Yearly maintenance by a professional storage heater professional such as My Local Electrician can help you keep your electric storage heaters running smoothly and safely.
- If your heaters boast programmable thermostats, make the most of their capabilities.
- Schedule your heating to suit your lifestyle, providing warmth when you’re home and conserving energy when you’re away.
- Regularly review your heating costs to spot any unexpected spikes. Adjust your settings and habits as needed to keep expenses in check.
