FAQs
Renata Single Vertical 1800 x 520 in RAL 9007
Choosing the Right Radiator
To establish how much heat your room needs, consult your Gas Safe registered installer or heating engineer. If you want to work it out yourself, visit our Heat Output Calculator . All our radiators are shown with their heat outputs, so you can choose a radiator or a number of radiators whose outputs add up to the heat you need.
All outputs listed are calculated in line with the European BSEN442 Testing Standard at Δt50°C (the latest standards for modern boiler systems). To convert Δt50°C to Δt60°C simply multiply x 1.264.

Radiator Positioning
In modern homes, radiator positioning is less important due to insulation and modern building regulations, however, please be sure to consult your plumber or heating engineer prior to purchasing and installation of your radiator. In traditional homes, most radiators are best placed in the coldest part of the room - usually found under a window, as this allows for airflow and radiant air convection. Large spaces are more effectively heated with 2 or more, smaller radiators rather than one large one.
A rule of thumb often used in the trade is to have one radiator every four metres (about 15 feet) or so in the room. An alternative could be two tall thin radiators on either side of the window or a long low radiator along the wall.
Positioning
Colours and Painting
Most of our radiators and towel rails are available in a range of colours. Each product page states the colours available for that specific product. In total, we offer 26 colours and 8 special finishes across our radiators and towel rails range, these can be viewed on our Colours and Special Finishes page.
Please note that due to the screen resolutions, printing process and manufacturing tolerances the colour (including white) of a finished radiator may vary slightly from the colours represented on the website. It should also be noted that if the same type of Radiators are ordered and produced at different times they may also differ marginally in finished colour from any previously ordered.
If in doubt you can order a colour chip sample; a tear-drop piece of metal finished in the colour or finish of your choosing.

Valves
The TRV controls the radiator's temperature by sensing the room air temperature and automatically opening and closing the flow to the radiator to maintain a preset temperature.
A manual valve controls the temperature of the radiator regardless of how warm the room already is.
TRVs are now a requirement as part of Building regulations, check with your installer to make sure you have the correct valves.
