What are standard size radiators?

While size or shape of space no longer needs to be a constraint, it’s likely that your existing radiators, if not installed in the last few years, do fit the previous standards for radiators. These were, traditionally, 700mm x 1400mm at the smallest and 600mm x 2400mm at the largest for horizontal radiators.

Which is best type 21 or Type 22 radiators?

The main difference between Type 21 and Type 22 radiators is the layers of fins, also known as the number of convectors. As you can imagine more is always better so Type 22 radiators typically generate much more heat than Type 21 radiators. This is down to the additional layer of fins inside.

How do I know what size radiator I need?

A quick and easy way to calculate the size of the radiator required for any room in your house is by measuring the room in cubic feet and then entering the information into a BTU (British Thermal Units) calculator found at the base of this page or using the table below to estimate the total BTU’s required to correctly …

What is Radiator Type 22?

A double panel convector radiator (also known as a Type 22) is an even more efficient and effective way of heating a room because it features two panels and two sets of convector fins, so the surface area of the radiator is vastly increased.

Are new radiators more efficient than old?

You may think all radiators are born equal, but you’d be wrong. In fact, modern radiators can be up to 50% more efficient than their year 2000 counterparts. This increased efficiency leads to a decrease in energy bills, meaning that your new radiators will eventually pay for themselves.

How do you size a central heating radiator?

To effectively calculate what the BTU output for any room is, you have to start by getting a tape measure and measuring the height of the room, the width of the room, the length of the room and then finally the size of the window area (that’s the length by width of a window in m²).

Which type of radiator is most efficient?

The best material for a modern radiator is aluminium. As we previously mentioned, Aluminium is better for heat transfer which makes Aluminium radiators incredibly efficient. They’re also very stylish right now and would look great in many rooms in the home.

What is the difference between a Type 11 and type 22 radiator?

Type 11 Radiator Sometimes called a K1 type, this design gives out the lowest heat, but is also much thinner than type 21 and type 22 radiators, so is perfectly suited to rooms where space is a premium.

Can a radiator be too big for a room?

A radiator that is not powerful enough will not be able to heat the room adequately, but a radiator that is too big will not only overheat the room but will cost you unnecessary money to run. A radiator’s size (or power) is measured in BTUs.

How many BTU do you need to heat a room?

To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.

Why do they put radiators under windows?

Windows are traditionally the worst insulated surfaces in a building shell. In the twentieth century, to combat that cold feeling and keep the room comfortably warm, radiators were always placed under a window. The rising heat of the radiator forms a kind of hot air curtain that shields you from the cold air.
