Buy Dimplex: The UK's Leading Electric Heating Brand

For over 75 years, Dimplex has been the trusted name for electric heating, and today remains the market leader in the creation and manufacture of energy-efficient electric heating products and solutions.

Part of the Glen Dimplex Group, the brand has built a global reputation for combining practical, user-friendly design with the latest heating technology — all with a strong focus on energy efficiency and sustainability. The origins of the Dimplex name are rooted in one of the very first products the company manufactured — an oil-filled radiator featuring distinctive dimples on its surface. This design not only improved performance but inspired the name that would go on to become synonymous with quality and innovation in the heating industry. Today, Dimplex heating products are used in homes, offices, and commercial buildings right across the UK and beyond, trusted by homeowners, landlords, and heating professionals alike.

Frequently Asked Questions

Are Dimplex heaters energy efficient?

Yes. Dimplex heaters are designed with energy efficiency as a priority. Many models feature built-in thermostats, programmable timers, and open window detection to avoid unnecessary energy use. Storage heaters in the range are specifically engineered to take advantage of cheaper off-peak electricity tariffs, making them a cost-effective long-term heating solution.

What is the difference between a Dimplex panel heater and a storage heater?

A panel heater heats a room on demand, producing warmth as soon as it is switched on. This makes it ideal for rooms that need heating at specific times of day. A storage heater, on the other hand, absorbs heat during off-peak hours — typically overnight — and releases it gradually throughout the following day. Storage heaters are generally more economical for properties on Economy 7 or similar tariffs, while panel heaters offer greater flexibility and instant control. Can Dimplex heaters be used as a primary heat source?

Yes, many Dimplex heaters are suitable for use as a primary heat source, particularly in well-insulated rooms or smaller properties. Dimplex storage heaters in particular are designed to provide whole-home heating as a standalone solution. For larger or open-plan spaces, a combination of Dimplex panel heaters and storage heaters can provide a practical and efficient heating system without the need for gas or traditional central heating.
