Terms to Know for Your Home Heating

Home heating can be a real head-scratcher. With all the terms and words melding into a hot pile of jargon, you might find it difficult to decipher your instruction manual. Whether you’re buying a new radiator from Great Rads or simply trying to refurbish your pre-existing one, there are plenty of terms out there to help you along the way.

From the simple to the downright complicated, we’ve compiled a glossary which explains some of the words that might come up during your radiator purchasing experience. This list only goes up to the letter H, but stay tuned for more terms for your radiator glossary!

Aluminium is one of the many materials that radiators can be made out of. With its lightweight and quick conduction time, aluminium has become one of the most popular materials to make heating units out of. Take a look at our range of aluminium radiators.


Radiator bleeding is the process of getting rid of any air bubbles that form inside your radiator’s body. The bleed valve on the top corner of a radiator gives you the ability to release any trapped air that could have built up and caused cold patches in your radiator unit.


British Thermal Units are the unit of measurement for the heat content of your radiator. One BTU is the amount of heat required to raise one degree of the temperature of one pound of liquid water. This is especially useful for radiators from companies like DQ Heating, who present the BTU of their products on each radiator they sell.

Calculate the BTU needed for your rooms by checking out our handy radiator BTU calculator.

Cast Iron

The traditional material that column radiators were made from in the Victorian era, cast iron is brittle and heavy, but is a sturdy and long-lasting material for your radiator, providing that you don’t mind the long heat-up times. Take a look at our range of cast iron column radiators.

Convector Fins

Convector fins increase the surface area of your central heating radiators or electric radiators by creating zig-zag shaped sheets of metal behind your radiator body. The convector fins of your radiator mean that your radiator can produce more heat for your room without taking up much more room in your home.

Designer Radiator

Designer radiators are modern, often boutique designed radiators that keep up with modern trends, alongside the needs of your home. Boutique designer radiators give you the opportunity to customise your model to suit your interior style and property’s needs.

Double Panel

Double panel radiators provide more heat by adding an extra panel to the radiator body. This extra piece of metal is often separated from the outside panel by internal convector fins and also allows water to run through it.

Dual Fuel

Dual fuel radiators are designed with a valve that allows you to swap between electric and central heating. This means that you can control whether your radiator works in tandem with or separate from the rest fo the radiators in your house, especially useful for hard to heat areas like the bathroom and the kitchen, which are used more sporadically than other rooms in the house.

Electric Radiator

Electric radiators are heating units that are plugged into the mains of your home and work separately from the central heating. This means that you can switch them on and off without affecting the rest of the home.

Flat-panel radiator

Flat panel radiators are built to save space and convey a minimalist aesthetic. These flat metal sheet radiators are often attached to the wall rather than the floor and come in a number of different finishes and colours.

Horizontal radiator

Horizontal radiators are radiators that utilise wall space rather than height. There are many subspecies of horizontal radiators, including column radiators, towel radiators and classic panel radiators.
