Storage heaters have been a fixture of UK homes since the 1960s. Affordable to install, and originally designed to take advantage of cheap off-peak electricity, they remain in tens of millions of properties — particularly in flats, social housing, and older homes without gas connections.

But as energy prices have risen and the limitations of storage heating have become harder to ignore, more and more homeowners and landlords are asking: is there a better option?

Infrared panel heating is increasingly being fitted as a direct replacement. In this article, we compare both systems across the things that matter most — warmth and comfort, running costs, damp and mould, control, and ease of installation.

How Storage Heaters Work

Storage heaters charge overnight using cheaper Economy 7 or Economy 10 electricity tariffs. They store heat in ceramic or brick-like core elements, then release it gradually throughout the day.

On paper, this sounds efficient. In practice, it creates several problems:

Heat Release Timing

Storage heaters release most of their stored heat in the morning and early afternoon — often when occupants are out. By evening, when the home is occupied and warmth is actually needed, the heater may be largely depleted. The result is a warm, stuffy morning and a cold evening.

Air-Based Heating

Like radiators, storage heaters warm the air. Warm air rises and stratifies — the ceiling is warmest, the floor is coldest. When the heater cools or the window is opened, this warm air escapes and the room must be reheated from scratch.

Limited Controllability

Older storage heaters have two manual controls: input (how much heat to store) and output (how fast to release it). Getting this balance right is genuinely difficult. Newer generation storage heaters have improved on this with automatic controls, but they remain fundamentally constrained by their charge-and-release model.

Running Costs

The Economy 7 and Economy 10 tariffs that made storage heaters economical are less advantageous than they once were. The unit rate for off-peak electricity has risen considerably, and the difference between peak and off-peak rates has narrowed. Many storage heater users supplement with portable electric heaters in the evening — adding to costs and negating any efficiency gains.

How Infrared Panel Heating Works

Infrared panels emit long-wave infrared radiation — the same gentle warmth produced by the sun. Rather than heating the air, infrared energy travels in straight lines until it is absorbed by solid objects: walls, floors, furniture, and people.

Those objects then radiate heat back into the space, creating a consistent, stable warmth that feels more natural than forced air heating.

Surfaces Warm First

This is the key difference from storage heaters. Infrared heats the building fabric — the walls, ceiling, and floor — rather than the air. Because the surfaces themselves are warm, the air temperature required to feel comfortable is lower. Most people feel comfortable at 18–19°C in an infrared-heated room versus 21–22°C in a conventionally heated one.

Immediate Response

Infrared panels reach operating temperature in minutes. There is no need to predict what heat you will need hours in advance. You turn the panel on when you need warmth; you turn it off when you do not. Combined with smart thermostats and scheduling, this gives precise control over when each room is heated.

No Stratification

Because infrared does not heat the air directly, warm air does not stratify. The temperature at floor level is close to the temperature at ceiling level, which means less heat is lost to the ceiling and the room maintains its warmth more evenly.

Infrared vs Storage Heaters: A Direct Comparison

Comfort

Storage heaters produce a convective warmth that many people find stuffy or oppressive at its peak, and inadequate in the evenings. Infrared produces a radiant warmth that is widely described as more comfortable and natural — closer to the feeling of sunlight on the skin.

Running Costs

Infrared panels typically operate at between 300W and 1,100W, and because they heat the building fabric rather than the air, the fabric retains heat for longer — reducing the total on-time required.

Storage heaters draw significant power overnight during their charging phase. Whilst the off-peak rate is lower than peak rate, the sheer volume of energy drawn — and the fact that much of it is wasted at the wrong time of day — often results in comparable or higher bills than a well-managed infrared system.

For properties with solar PV, infrared panels are an excellent match. Excess solar generation in the middle of the day can directly power infrared panels at zero marginal cost — something that is simply not possible with a storage heater charged overnight.

Control

This is where infrared has a clear advantage. Each panel operates independently and can be controlled by a room thermostat, a smart controller, or a central app. You can set different temperatures for different rooms, different schedules for weekdays and weekends, and adjust remotely from your phone.

Storage heaters, particularly older models, require you to estimate your heating needs the night before. Modern smart storage heaters have improved on this, but they are still constrained by their fundamental design.

Damp and Mould

This is one of the most practically important differences — particularly for social housing providers and landlords subject to Awaab's Law.

Storage heaters produce a burst of warm, moist air that rises to the ceiling and then cools against cold wall surfaces. This cycle of warm-humid air meeting cold surfaces is precisely the mechanism that causes condensation and mould growth.

Infrared, by contrast, warms the wall and ceiling surfaces directly. When surfaces are warm, they remain above the dew point — the temperature at which moisture in the air condenses. No condensation means no mould. This makes infrared panels significantly better than storage heaters at preventing and eliminating damp.

Properties switching from storage heaters to infrared typically report a marked reduction in condensation within weeks, with mould eliminated entirely within a full heating season.

Installation

Both systems run on standard 230V single-phase electricity and require no gas connection. Storage heaters are large, heavy units fixed to the wall at skirting level. Infrared panels are slim (typically 20–25mm deep), lightweight, and can be ceiling- or wall-mounted — keeping floor space clear and enabling better heat distribution.

Replacing storage heaters with infrared is straightforward. The existing electrical wiring can typically be repurposed, and there is no requirement for new pipework, boilers, or pressure testing.

Environmental Impact

Both systems run on electricity, so their carbon footprint is directly tied to the grid's generation mix. As the UK grid continues to decarbonise, both systems become greener over time. However, infrared panels tend to use less energy overall due to the efficiency gains from heating surfaces rather than air — giving them a marginal but real environmental advantage.

Who Should Consider Switching?

Infrared heating is particularly well suited to:

• Properties without a gas connection — flats, rural homes, older housing stock

• Social housing providers replacing ageing storage heater stock and seeking Awaab's Law compliance

• Properties with damp or mould problems where storage heaters are contributing to condensation

• Homes with solar PV where daytime generation can offset running costs

• Landlords wanting lower-maintenance, longer-lasting heating systems with individual room control

The Verdict

Storage heaters served their purpose in an era of cheap overnight electricity and limited alternatives. That era is over.

Infrared panel heating offers better comfort, more precise control, comparable or lower running costs, and — critically — a fundamentally different relationship with moisture. By warming surfaces rather than air, infrared removes the conditions in which condensation and mould can form.

For social housing providers, landlords, and homeowners looking to upgrade from storage heaters, infrared is a proven, practical, and future-proof replacement.
