Electric Heating

Introduction

The heating industry has undergone significant changes over the last decade, becoming almost unrecognizable with the commonplace adoption of renewable technologies. New innovations, technologies, and legislation have collectively transformed the products we use, with energy efficiency emerging as a primary driver for these shifts.

The electric radiator market has also evolved, with designs and functionalities now aligning with homeowner demands. Gone are the days of bulky storage radiators and unappealing panel convector heaters. Modern electric radiators are sleek and minimalist, fitting seamlessly into contemporary home aesthetics and posing a significant alternative to traditional gas central heating systems.

Beyond their appearance, electric radiators offer substantial functionality and control, appealing to heating specifiers seeking more than just a cost-effective solution. They are expected to deliver on energy savings, safety, ease of installation, controllability, design, versatility, and comfort – a comprehensive set of requirements that electric radiators are now capable of meeting.

Versatility

Electric radiators are now simple and quick to install, allowing placement almost anywhere within a property. Larger units can effectively warm substantial rooms, making them ideal for areas where extending or installing a central heating system is impractical. They can be retrofitted independently of existing hot water systems, eliminating the need for additional pipework or a higher-output replacement boiler.

Their versatility extends to various applications, including apartments, houses, and offices. Unlike traditional gas systems, electric radiators require no annual maintenance or servicing, making them a preferred choice for landlords. Furthermore, if additional heating capacity is needed later, electric radiators can be easily added to the existing system.

Energy Savings

Modern electric radiators now rival traditional gas heating systems in terms of energy savings. While they are cheaper to install and maintain than gas systems, their running costs are also competitive. Electric radiators have shed the stigma associated with inefficient, inflexible storage heaters of the past.

Today's electric radiators are 100% efficient at the point of use, meaning all electrical energy input is converted directly into heat output. Sophisticated programming devices and controls ensure that only the electricity necessary to maintain comfortable temperatures is used.

The heating process involves both radiant and convection heat. Convection warms the air, circulating it throughout the room, while radiation heats people and objects directly. Electric radiators warm the air from beneath, using natural convection currents to distribute warmed air. Once the room reaches the set thermostat temperature, the heating element shuts off. When the temperature drops, the thermostat reactivates the unit.

A thermostatically controlled electric radiator typically draws power for 30-50% of the time to maintain room temperature. For example, a 1.5kW radiator might use up to 750 watts per hour, depending on the room's heat loss, while keeping the space and occupants warm.

Controls and Comfort

Inflexible control is now a relic of the past, thanks to advancements in electric radiator technology. Modern systems offer highly accurate digital controls for time and temperature, with some, like Electrorad's Digi-line range, achieving +/-0.1°C precision. Each emitter has its own controllable element, allowing an entire system to be linked to a central room controller and programmed for specific heating needs.

Wireless radiators are gaining popularity, especially in new builds, due to their slimline design and fully programmable remote RF controls. These systems can be zoned, enabling radiators to turn on and off automatically based on the temperature requirements of each zone. This zoning capability allows for control of separate floors or areas, preventing energy wastage by heating unoccupied spaces.

Some of the latest electric radiators even feature integrated smart meters.

The beauty of electric radiators is that they produce both radiant and convection heat – convection warms the air and circulates it around the room, whilst radiation heats people and objects directly. Electric radiators warm the air from beneath the heater and, by using natural convection currents, circulate the warmed air throughout the room.

Design

The aesthetic appeal of modern electric radiators has significantly transformed the electric heating market. Homeowners increasingly expect heating products to be both functional and visually pleasing, often requiring them to complement their home décor. Many new products originate from Spain and Italy, reflecting a design aesthetic that often mirrors traditional European central heating. In contrast, Electrorad's Digi-line range emulates the look and performance of classic British central heating.

Today's electric radiators represent a significant leap from models of ten years ago, offering enhanced comfort and sophisticated controls. This facilitates precise management of energy usage and efficiency. As energy efficiency remains a key concern, electric radiators are well-positioned to continue gaining market share against traditional heating systems.

The demand for electric radiators has seen exponential growth in recent years and is projected to continue. With increasing sales, a wider product selection, and greater availability, the future market for electric radiators looks promising. Perceptions have shifted dramatically; no longer considered the inferior option to gas central heating, electric radiators are on an upward trajectory.

The optional central programmer on the Digi-Line radiator is battery powered and uses radio frequency signals to communicate with the radiators so no wiring is required.

Safety

Significant advancements have also been made in electric radiator safety. Unlike earlier models, contemporary radiators feature sealed hot elements immersed within fluid inside the metal casing. This design prevents dust and objects from falling onto the elements, enhancing safety for operation and touch.

These safety features, combined with high-quality components, allow some electric radiators to offer superior guarantees. For instance, the Aeroflow range provides a 30-year warranty covering all internal components (electric elements, thermal switches, and wiring), excluding the thermostat. This warranty is among the most comprehensive in the industry.
