Yes, you can absolutely replace just one storage heater, and for many households in the UK this is often the most sensible place to start, rather than committing to a full heating system change all at once.
Night storage heaters are usually installed throughout the property, but there is no rule that says they all need to be replaced together. If one room is uncomfortable, expensive to run, or simply no longer meeting your needs, you can upgrade that single heater independently and leave the rest of the system in place.
In fact, this approach is becoming increasingly common as homeowners look for more flexible and cost-effective ways to improve comfort without a full renovation.
Many people do not replace all of their storage heaters in one go. Instead, they start with the room that causes the most frustration; usually the living room or main bedroom.
Night storage heaters release heat gradually from the overnight charge, which means they are often warm in the morning but cold again in the evening – when you actually need heat the most. This is one of the main reasons our customers replace their storage heaters.
Replacing just one heater with an ELKATHERM® electric radiator allows you to experience the difference in comfort and control before making decisions about the rest of your home.
When you replace a night storage heater with an ELKATHERM® electric radiator, you are not just swapping one heater for another. You are upgrading the way that room is heated.
ELKATHERM® radiators are designed with a high density fireclay storage core, which heats up quickly and stays warm for hours with minimal top-ups. Unlike traditional storage heaters that are locked in to off-peak charging times, ELKATHERM® radiators give you full control over when and how the heat is delivered.
That means you can heat the room exactly when you need it, whether that’s in the morning, afternoon, or evening, without waiting for a night charge cycle. The result? A much more responsive and comfortable heating experience, particularly in living spaces that are used at different times throughout the day.
Yes. In many cases, it’s one of the most practical ways to start improving your heating system.
Replacing one storage heater allows you to target the worst performing room first. This is often where the biggest comfort issues are felt, and where the improvement is most noticeable.
Many homeowners choose to upgrade in stages, rather than all at once. Once they experience the difference an ELKATHERM® radiator makes in one room, they often decide to gradually upgrade the rest of the property over time.
Replacing a single night storage heater is often a very straightforward installation. In most cases, it can be done with minimal disruption, especially when there is already an existing electrical supply in place.
The cost does depend on the size of the room and the power output required, but starting with one radiator allows you to spread your investment over time, rather than committing to a full system replacement upfront.
We recommend booking a free home survey, where one of our advisors will ensure your new radiator is correctly sized for the space in order to provide you with efficient and consistent heat.
There is no one size fits all answer. Some homes benefit from a full upgrade, especially where very old storage heaters are installed throughout the property. However, many customers prefer to start with one room and expand gradually.
Starting with just one ELKATHERM® radiator gives you a low-risk way to test performance, improve comfort immediately in your most used room, and make informed decisions about future upgrades.
If you’re struggling with an old storage heater that no longer keeps your home comfortable into the evening, replacing just one heater with an ELKATHERM® electric radiator can be a simple and effective first step.
It allows you to modernise your heating room by room, improve your comfort where it matters most, and move away from the limitations of outdated Economy 7 storage heating without a full system replacement upfront.
