Home Owner

Renaissance Radiators are perfectly positioned between the heritage and charm of historic design and the pragmatic efficiency required of 21st century heating. 

With an extensive range of period and contemporary models, inspired in style from original designs, it is possible to extend an authentic theme through the exquisite detailing and high quality finishes inherent in the Renaissance range.

Easy Online Ordering

Our web page is easy to navigate and allows you to place your order in a step by step approach.  We also have a BTU calculator on each radiator page that allows you to easily determine the size of radiators you need for each space you wish to heat.  It could not be easier, simply enter your room sizes to obtain a BTU requirement.


Everything You Need

With an extensive range of traditional and contemporary styled valves, pipe shrouds and wall stays in a choice of complementary finishes, Renaissance Radiators are able to provide you with a full set of products so your order is ready for installation on arrival.  



When it comes to building design, heating the internal space comes high on the list of considerations.  We understand that the type and style of heating needs to be built into the fabric of the design as it can have an immense impact on the aesthetics created in the completed project. Functionality is certainly a key factor in determining the best heating solution but that does not have to mean compromising on style.  Our cast iron radiators are available in a range of traditional and contemporary designs and deliver the same economies as standard white panel radiators.

Care and attention to detail matter

Our radiators are assembled and finished by hand in our UK based workshop and are subject to regular inspections, carried out at each stage throughout the process:

Crisp detailing is achieved in each of our radiator sections by sand casting using CNC moulds and 3D modelling techniques.

After being hand assembled to order and painted or finished according to your specification, each radiator is subjected to a rigorous, high pressure testing process for in excess of 24 hours at water pressures that exceed the normal water pressure found in UK domiciles.

To ensure your tested product reaches you in pristine condition the tested radiator is handed back to the spray technicians for an overspray which completes our dual painted process ensuring a high quality finished product.

A final inspection allows us to give our full Quality Control stamp of approval and the order is then ready for despatch.
