At Howarth, we have a range of high-performance compact radiators to warm up any room in your house. Compact radiators are one of our most popular radiators, mainly due to their neat, compact, and simple design. They also fit in with other traditional and modern house interiors.

Types of radiators

Type 11 radiator: A single panel with a single convector, and one of the most common compact convector radiators, mainly due to how affordable they are. They are also the perfect radiator to be fitted into a type of small room like an office. They come in various heights from 300mm up to 750mm.

Type 21 radiator: A double panel with a single convector, these types of radiators are perfect for small to small-medium rooms because of how the double panels offer more heat than the single panel option. These are available from 400mm in height, up to 750mm in height and include both a front and back panel. These radiators are great for small to medium sized rooms, as the double panels offer more heat than the single panel option.

Type 22 radiator: A double convector radiator with a double panel, these radiators are available in heights from 300mm to 750mm and have two convectors which are great for creating larger heat outputs without the need for a larger radiator.

Radiators are a necessity when heating up your home, and they can also be of multipurpose. The style makes them ideal for drying clothes, as the heat rises through the grilles on the top. They sit close to the wall and are attractive and modern in appearance.

For further expert advice and guidance on which type of radiator would be best for your home, please contact your friendly local Howarth branch.

Frequently Asked Questions

What size radiator do I need?

To figure out what size radiator you may need for your room, you can use a radiator BTU calculator tool online.

How does a radiator work?

Radiators work through a heat transfer process called convection. This means that when water in the radiator is heated, the surrounding air is also heated up via convection and this hot air is then moved around the room as the air circulates.

How to measure a radiator?

Take your tape measure from the lowest point of your radiator to the highest.

Can you paint radiators?

Yes, you can paint radiators.

When to bleed radiators?

Radiators need bleeding when they have air trapped inside of them. If your radiator is cold at the top, but warm at the bottom, it usually means they need to be bled.
