  • Here we present 16 different colour options, all professionally presented showing you a how the full size radiator will look in each colour.
  • Some of the colours shown above are smooth, flat colours and others are matt, textured colours. See the respective descriptions on each colour for detailed notes of the textures.

  • The "Tesi" range of Traditional Column radiators from reputable brand, IRSAP, are extremely high quality products covered by a 10 year guarantee, available in an extensive range of sizes and colours. Bespoke custom sizes are also available, more information further down this page.
  • The IRSAP manufacturing plant, located just outside of Venice, is state of the art and all radiators are laser welded on huge robotic arms which ensure absolute precision and consistent quality across every model.
  • All of these radiators are supplied with an internal diverter (radiator baffle) which forces the water up and over inside the product, which ensures all the bars get equally hot. This is removeable in case the plumber wants to pipe in from the top and out from the bottom. In this case the diverter won't be needed.
  • FOR THE FITTER: This radiator will be heavy once filled with water. It is supplied with standard wall mounting brackets, which are very strong. However if you know you have weak timber frame walls we strongly suggest you also consider the following:
    • ordering some special plaster board plugs - see our accessories catagory our website.
    • special ordering your radiator with welded feet, which are floor standing feet, fitted to the radiator, supplied in the same style and colour as the columns of the radiator, so you can mount the product on the floor. These have to be fitted at time of manufacture so your radiator will incur a 4-6 week lead time.
    • ordering additional gravity support feet for the product - only compatible with white, black, cream or lacquered metal which will be in addition to the standard wall brackets supplied. These can be purchased here on the website today allowing you next day delivery of the radiator and the gravity support feet.
  • To the right of this description there are clickable drop downs showing the available types of accessory we offer to match these column radiators.
  • All special order colours carry a 4 to 6 week lead time from order. Lead times are a guide not a promise but we achieve these 90% of the time.
