Types of space saving radiators

There are several types of small radiators that can help you to save space in your home. These include:

  1. Narrow vertical radiators – These are often very tall, with heights up to 1800mm and widths as little as 225mm which allows them to fit snugly in most rooms.
  2. Short horizontal radiators – These are the perfect choice for fitting underneath low windows or within conservatories.
  3. Small towel warmers – The obvious choice for small bathrooms, cloakrooms or downstairs toilets where space is in short supply but you also need to keep towels (or coats) dry.
  4. Electric Plinth heaters – These are a fantastic solution for kitchens that lack wall space due to kitchen cabinets and appliances taking up space. These plinth heaters fit snugly underneath your units and blow out soothing warm air on your feet which rises up into the room.
  5. Portable electric heaters – Ideal if you have several small spaces that need heating at different times of the day. Simply unplug the heater, take it into another room, plug it in and away you go!

How small is too small?

Obviously, you’re going to need a small enough radiator that will fit comfortably into the limited space that you have. Although, you might also like to consider that the smaller the radiator is, the less heat output it’s going to generate. You can use our free BTU calculator to work out exactly how much heat your room will require. This will ensure that the room is kept toasty warm all year round.

What are the best space saving radiators for different rooms?

If you want to make sure that you choose the right size radiator for each room then here are some tips:

Kitchens – A narrow vertical radiator is ideal for keeping your kitchen warm throughout the winter months. It should sit near a window or ideally be placed close to the door to maximise its effectiveness.

Bathrooms – The bathroom is usually the smallest room in any house and therefore needs a radiator that’s as compact as possible. A short horizontal radiator is perfect for this purpose, especially when fitted under a window.

Downstairs toilet – A dinky electric towel warmer works well in this situation because it fits neatly beside the toilet where you can conveniently hang and dry hand towels.

Bedroom – A narrow vertical radiator is great for bedrooms because it doesn’t take up much floor space. However, it’s important to remember that the height of the radiator affects the amount of heat that it generates. Therefore, if you want maximum warmth, you may need to invest in something taller.

Cloakrooms – A small wall-mounted towel warmer works great in a cloakroom because you can hang up your wet coats and dry them on the radiator itself or the radiant heat can keep moisture at bay for the entire cloakroom.

Living Room – A short horizontal radiator is a good option for living rooms because it won’t take up much space. However, it does mean that you’ll need to keep an eye on the temperature so that it doesn’t get too hot.

Conservatory – A short horizontal radiator is a must-have for your conservatory as it can fit neatly underneath the large windows; helping to reduce the amount of cold air that drops down from the window ledge onto the floor.

Does a small room even need a radiator?

This will depend on several factors, such as the heat loss properties of your home, the location of the room and the surrounding insulative features. If you take a look at our room BTU calculator you’ll be able to find out exactly how much heat your room requires in order to be heated sufficiently all year through.

You should also consider things like:

  • How often you’ll be in the room
  • Is it just used for storage
  • The cost associated with heating the room

Our website has lots more information about choosing the correct radiator for your particular circumstances. We hope that this article helps you to understand the heating options available for small rooms and awkward spaces in your home.
