Designer Radiator FAQ's

The top 11 designer radiator FAQ's you need to know before buying a designer radiator.


No 1 Designer Radiator FAQ: Can I change the radiator in just one room?

Yes, within an existing system you can replace all the radiators or just the ones you want, when you choose to. Designer radiators have common pipe fittings, the same as standard radiators and are compatible with normal central heating systems that have British Standard fittings. You can fit a designer radiator in your home, and it will work alongside standard radiators. However, it is important to know what material the radiators already connected to the system are made of, as the two major materials, steel and aluminium, used in the same system, might lead to corrosion damage. For this reason do not buy an aluminium radiator if the other radiators on the system are steel radiators. We advise you to consult a heating engineer or a competent plumber.

No 2 Designer Radiator FAQ: Are all designer radiators guaranteed?

Yes and No. Every Agadon designer radiator comes with a 10 year no quibble product guarantee.*  However, many online retailers of designer radiators give the promise of a guarantee but it's not a manufacturers guarantee. Why is this important? Well, if they have only been in business for a couple of years - and they have an issue with radiators purchased in bulk at rock bottom prices and sold on to consumers - then they haven't got the manufacturing base to get the issues fixed or replace with an non-faulty radiator. So it's crucial you check out the company you're buying from - see if they have a showroom you can visit, get a feel if they are credible or just in it for a fast buck!

*Agadon offers a 10 year guarantee on all of its products, this covers the product and the finish (our painted radiators are powder coated - this is also covered by the guarantee).



No 3 Designer Radiator FAQ: Why are the radiator valves sold separately?

The type of radiator, location within the room and look your after, mean our radiators and accessories are often a unique combination to suit your needs. Selling the radiator valves separately means you get more choice on the possible options to complement and enhance your designer radiators' look and functionality. Radiator valves are an indispensable part of your designer radiators or heated towel rails because it allows you to control the heat output of an individual radiator with a TRV (Thermostatic Radiator Valve) this means each room can be set to its own desired temperature.

What is a thermostatic radiator valve?

A Thermostatic Radiator Valve (TRV) is a type of radiator valve that gives you greater control over the heat in each room. Each TRV can be set to a temperature to suit you, so you can have different temperatures in different rooms.

No 4 Designer Radiator FAQ: Which are the best designer radiators?

It's a question often asked but in real terms, it depends on what you need. The styling, colour or finish of a radiator are all subjective – but what one person likes in a designer radiator, another person may not.

No 5 Designer Radiator FAQ: What is the best designer radiator for your heating needs?

Heat output is an objective criteria measured in BTU's. BTU is an acronym, it stands for British Thermal Unit. It's a form of measurement that measures energy. To get an idea of the heat output you need for the specific space, you can use our Radiator BTU Calculator. The radiator calculator helps you work out how much radiator heat you need. To heat a room, you'll need to enter the details in the BTU Calculator - this will give you the heat output in BTU's required to efficiently heat the space. Remember you can have one high performance radiator or two or three radiators sharing the load.

No 6 Designer Radiator FAQ: Do designer radiators give enough heat?

Designer radiators come in a very broad range of shapes, sizes and finishes. They are obviously amazing for adding a touch of style to your room but can also be adaptable to suit difference spaces in a way that standard panel radiators can’t. But however great they look, sometimes they won’t offer the same heating performance as a standard radiator.




No 7 Designer Radiator FAQ: Are anthracite radiators more efficient?

Anthracite radiators are highly effective, and can give each space a more sophisticated appearance, which is why interior designers love them - but are they more efficient?  Anthracite radiators are about 1% more efficient than a lighter coloured radiator.

No 8 Designer Radiator FAQ: Can a single radiator be replaced with a double radiator?

You can replace a single for a double radiator to enjoy higher heat outputs or just for a different look. However, there are a few things that you’ll need to take into consideration before you make your selection for your new double radiator. One of the most common difficulties of replacing a single radiator with a double is that the size of the new radiator hasn’t been checked properly and the pipework doesn’t measure up. Double radiators also have different brackets from their single counterparts, so you’ll need to be prepared to remove the old brackets and add a new set before you finally hang your new double radiator.




No 9 Designer Radiator FAQ: Are vertical or horizontal radiators best?

A better question would be which one is the right type of designer radiator for your room – horizontal designer radiators or vertical designer radiators? In terms of heating a room, it doesn’t really matter whether the radiator you choose is horizontal, vertical or square. Modern radiators are available in just about every shape you can conceive.



No 10 Designer Radiator FAQ: Where's the best place for a radiator?

The short answer it depends upon the room shape and size, how you use the room, plus any existing radiators.  Sometimes the smallest and most efficient wall space to use is underneath a window which means a horizontal radiator is the obvious choice.  Other times it’s a jutting out wall keeping up the wall between a new extension and the old house, this would mean a vertical radiator would be best. If the room needs more heat, you could add an infrared panel radiator, with the added flexibility and freedom you'll get - because this only needs a power supply. If you are looking for a quick upgrade for your home’s heating, more often than not, it is easier to select a like-for-like swap of the horizontal radiators you already have in place. When it comes to wall space though, you would have a little more to play with if you were to install the vertical design instead of the horizontal radiator.
