RUTLAND RADIATORS

1. INTRODUCTION

Undertaking the replacement of a property’s radiators can be a daunting task for even the most experienced designers & architects.

Rutland London has years of experience in supporting clients with the replacement of their radiators and as such, is well placed to support you. All radiators offered by Rutland London are intended to capture our vision of offering products of enduring quality and timeless style.

Whilst this guide is not intended to be definitive, it is hoped that the information contained below will provide you with a good understanding of the steps involved in selecting new radiators for your project.

Our experienced colleagues remain available to assist you before, during and after the purchase of your radiators from Rutland London and therefore, should any queries arise following your review of the below guide, please do not hesitate to get in touch.

Please note: in all instances, Rutland London recommends that you consult an experienced and competent heating engineer prior to commencing works or ordering radiators as Rutland London cannot accept any design responsibility.

2. RADIATOR SELECTION

Choosing your preferred type and style of radiator will provide you with a basis from which to form your next design decisions. Radiators from Rutland London are offered in two types, cast iron and steel. Each of these types has their own unique characteristics which should be considered prior to purchase:

CAST IRON RADIATORS

Cast iron radiators offer a unique aesthetic which makes them ideally suited to historic properties. In addition, the way by which they are built means that they can be assembled in England allowing for shorter lead times.

However, cast iron radiators are extremely heavy (in some instances they weigh in excess of 250kg) and can be more complex to install due to the joint design between sections. Both of these factors can be easily overcome, but should be considered prior to purchase.

STEEL RADIATORS

Steel radiators capture a timeless aesthetic which effortlessly blends with both traditional and contemporary settings. Manufactured to order in Italy, steel radiators are considerably lighter than their cast iron counterparts and are considered to be easier to install due to being manufactured to size at the foundry rather than assembled from sections as is the case with cast iron.

However, due to being manufactured to your required size at the foundry in Italy, steel radiators often are associated with longer lead times. In addition, due to the tubular style, there is less availability in styles than is found with cast iron.

Each of the benefits of the available types of radiators should be discussed with your installer prior to purchase to ensure compatibility with your heating system and project.

Once you have identified your preferred type of radiator (cast iron or steel) you should then identify the style of radiator you prefer. At this stage, you should not overly worry about sizing, but instead focus on the various aesthetic styles available and whether you require floor mounted, or wall mounted radiators.

3. CALCULATING HEAT REQUIREMENTS

Ensuring your radiators are correctly sized for each respective interior space within your project is essential to ensure the efficient operation of radiators once installed. To ensure accuracy, we recommend you arrange for your heating engineer to undertake a detailed survey whereby property construction type, room sizes and window details are all captured amongst other relevant characteristics which can affect your heating requirements.

For those working with historic properties, it is always helpful to advise your heating engineer of any unique requirements such as draughty windows so that a pragmatic view can be taken as to what impact this may have on your heat requirements.

During this survey, your heating engineer should also look to confirm the Delta at which your heating system is operating. Most modern heating systems (powered by a condensing boiler) operate at Delta T50 but if you operate an air source heat pump, your Delta may be lower.

Once this survey has been completed, you should have a wattage requirement* for each space which will inform your decision with regards to sizing alongside any size limitations which you need to be aware of.

*Please note: in the latest guidance (2014 onwards), radiator heat outputs should be in Watts. Many engineers and designers still work in BTUs and Rutland London would be delighted to assist you in converting from either unit.

4. UNDERSTANDING LIMITATIONS

Alongside collecting heat output requirements, you should also record any limitations which may limit your choice of radiator. Common limitations include:

EXISTING PIPEWORK

Particularly in historic properties, pipework may not be able to be moved. In addition, it should be noted that moving pipework can be costly.

WINDOWS & FEATURES

Often, the height of window sills and other features within your space may limit your options when it comes to sizing your radiators. 

COST & LEAD TIME

Ordering bespoke sized radiators may ensure you are able to meet heat requirements, but bespoke radiators are often more expensive and can take a little longer to manufacture. It should however be noted that bespoke sizing may save money on installation if the product can be manufactured to meet your existing pipework arrangements.

5. RADIATOR SIZING

Once you have identified your required heat requirements along with any limitations, you should now be in the position to “size” your radiators. There are three ways to approach this:

HEAT OUTPUT BASED

Ideally suited to new-builds where limitations may be minimal, this approach looks purely at the heat output required in each space. If for example you require 770 Watts, you would specify a suitable radiator (with an output within 10% of this figure) regardless of size.

This approach can lead to clashes onsite if limitations are not considered, but does generally ensure your radiators will provide a sufficient heat output.

LIMITATION BASED

This approach looks purely at the limitations and bases the radiator sizes on these. This is a common approach in historic / listed properties where there may be an obligation for radiators to match the sizes of previous radiators as closely as possible.

This approach can lead to radiators being inefficient due to either underheating or overheating the space.

HYBRID BASED

This hybrid approach is the preferred sizing method in most instances. It aims to balance your heat output requirements with any applicable limitations to identify required radiators which satisfy both requirements and limitations.

6. COLOUR SELECTION

The final part of selecting your radiators is to confirm your preferred colour for each radiator. Rutland London is able to offer our radiators both in a range of standard colours, but also in a colour of your choice from popular paint brands including Farrow & Ball, Little Greene, Edward Bulmer and Paint & Paper Library amongst many others.

Paint finishes are achieved with a '2-pack' paint formula similar to that used by the automotive industry and are applied via complex compressed air systems to ensure a uniform, durable finish.

7. FUTUREPROOFING

There is no doubt that luxury radiators are a significant investment which we hope will serve you for many years to come. However, there are several considerations which albeit not exhaustive, should be considered when specifying your radiators.

UK policy appears to focus ever-more closely on air source heat pumps (ASHP) and therefore we consider it to be prudent that you consider this when specifying radiators. As a rough rule-of-thumb, the resultant impact of an air source heat pump is that your heating system will likely operate at a lower delta - eg, Delta 30. A lower Delta will mean you will need to increase the size of your radiators.

"As an architect, I frequently specify fine radiators and vanities for residential projects in Central London, and I believe Rutland are amongst the very best available. Not only are they a great team to deal with, but the products are beautiful and well crafted, and made in England"

Simon Templeton - Architect, Central London

"Rutland hand-made towel radiators for our chalet in France and my biggest regret is not having them produce all the hardware throughout! The Rutland team were a dream to work with and helped us troubleshoot the many challenges we had building in a foreign country."

Sara Harbert - Morzine, France

"We have used Rutland on a number of residential projects and have always been really pleased with their products, finish is great, and delivered within agreed lead times."

Guy Wengraf - Vitruvius & Company
