Understanding Your Storage Heater Controls
Many homeowners grapple with the dials and levers on their storage heaters, often leading to wasted energy and unnecessarily high bills. The fundamental principle behind these units is simple: they absorb heat from the electricity supply during off-peak hours, typically overnight under an Economy 7 tariff, and then release it throughout the day. Getting the 'settings' right, therefore, involves a balance between charging enough heat and not overheating your home. The most common controls you'll find are the input control (often labelled 'input', 'charge', or 'day') and the output control (labelled 'output', 'heat', or 'thermostat').
The input control dictates how much electricity the heater draws during the charging period. Turning this up means the heater will get hotter and store more heat. The output control, conversely, regulates how much of that stored heat is released into the room. It effectively acts like a thermostat, opening vents to allow heat out as needed. Misunderstanding these two is a primary reason for setting storage heaters incorrectly.
Common Mistakes in Setting Storage Heaters
One of the most frequent errors is turning the output control up too high throughout the day. This releases all the stored heat prematurely, leaving you cold by the evening and forcing you to rely on less efficient supplementary heating. Another pitfall is setting the input control too low during the night. This results in insufficient heat being stored, meaning the heater won't provide enough warmth the following day, regardless of how high you set the output. It’s a common misconception that simply turning everything to maximum is the solution; in reality, this leads to overheating and significant energy wastage.
Mistaking the purpose of the input and output controls is pervasive. People often fiddle with the output dial throughout the day, expecting it to 'top up' heat, when its primary role is to manage the release of pre-stored heat. If you find your rooms are too warm, the instinct might be to turn the output down, which is correct. However, if they are too cold, many incorrectly assume they need more heat *now*, rather than adjusting the input for the *next* charging cycle.
Finally, neglecting seasonal adjustments is a considerable oversight. Storage heaters are designed to work with varying ambient temperatures. Continuing to use the same settings in milder spring or autumn weather as you would in the depths of winter is inefficient. The goal is to achieve comfort without unnecessary expenditure.
Correctly setting your storage heaters requires understanding the difference between charging heat and releasing it, aligning settings with the day's expected temperature.
Adjust your input control based on the forecast for the *next* day, not the current temperature.
Why Setting Them Incorrectly Costs You
The primary reason for correctly setting storage heaters relates directly to affordability. These systems are most economical when used with an off-peak electricity tariff like Economy 7. If you fail to store sufficient heat, you'll be left cold and may resort to using expensive peak-rate electricity for other heaters, negating the savings. Conversely, overcharging means you're paying for heat you don't use, which dissipates into the atmosphere, wasting electricity and money. This is particularly true for older, less efficient high heat retention storage heaters where heat loss can be more pronounced if not managed.
Beyond the direct cost, inefficient operation can lead to discomfort. A room that's too cold is unproductive and unpleasant, while a room that's too hot is stifling and can even encourage mould growth. Getting the balance wrong means you’re not only spending more than you need to, but you're also not enjoying your home as you should.
The effective lifespan of your storage heater can also be indirectly impacted. While they are robust, consistently running them at extreme settings could potentially put undue strain on components over long periods, though this is less common than the financial and comfort implications.
The true cost of inefficient storage heater use is a combination of wasted energy and compromised comfort, both of which directly affect household budgets and well-being.
Achieving Optimal Storage Heater Settings for Savings
Setting your storage heaters for optimal performance and economy involves a thoughtful approach rather than guesswork. The key is to tailor the settings to your household's needs and the prevailing weather. For most people using Economy 7, the strategy revolves around the night-time charge and the day-time release.
Step-by-Step Guidance for Setting Your Heaters
Start by identifying your heater's controls. Typically, you'll have an input dial (often numbered 1-10 or similar) and an output dial (also numbered or with symbols indicating heat flow). You'll need to understand your local electricity supplier's off-peak hours for Economy 7 to ensure the heater is charging when it's cheapest.
- Initial Setup: Before the heating season begins, set the output control to a moderate level, perhaps midway. Observe how much heat your rooms retain throughout the day.
- Adjusting the Input: If you find your rooms are too cool by the afternoon, increase the input control for the next charging cycle. If they are too warm and you're wasting heat, reduce the input. The aim is to store just enough heat to maintain comfort until bedtime without overheating.
- Fine-Tuning the Output: Use the output control to manage the release of stored heat. If a room becomes too warm during the day, simply turn the output down. If you need a little more warmth before the next charge, you might turn it up slightly, but be mindful that this draws from the stored heat.
- Seasonal Changes: During milder weather, significantly reduce the input control. You may not need a full charge every night. In very cold spells, you might need to increase the input slightly, but avoid overcharging.
For modern Dimplex Quantum or high heat retention storage heaters, the principles are similar but controls might be more sophisticated, sometimes digital. If you have a Dimplex Quantum, for instance, it often has intelligent controls that learn your habits. For older Creda or other models, manual adjustment remains the norm.
Experiment with small adjustments to the input dial over a week to find the sweet spot for your home's heating needs.
When to Call a Professional
While setting storage heaters is largely a matter of understanding their controls and your home's usage, there are times when professional help is advisable. If your heaters are making strange noises, emitting unusual smells, or not heating up at all, it could indicate a fault that requires expert attention. Similarly, if you've tried adjusting settings and are still experiencing significant temperature fluctuations or excessively high bills, an electrician or heating engineer can assess your system's efficiency and identify potential issues. They can also advise on whether newer, more efficient models, such as those with better insulation or smart controls, might offer long-term savings compared to your current setup.
The decision to seek professional advice should be based on safety concerns or persistent operational problems, not just unfamiliarity with the controls.
