If you are installing a ground source heat pump system then we recommend reducing our Delta 60 figures by 20%. This is to compensate for the lower water temperatures that these operate at. Cast Iron Radiators have an operating characteristic of retaining the heat for longer periods which makes them ideal for use with Ground Source Heating Systems.


Some ground source suppliers are recomending that you work to Delta 30 figures -
To work out Delta 30 from our website Delta 60 figures - you just need to add an extra 30%

So for example if our website is telling you that you need a 10 section radiator - then if you are installing in a Delta 30 heating system you would need to use a 13 section radiator.



What is delta 60?

The figures that we quote on our website are at delta 60 - this is basically 80 degrees C output from most central heating boilers versus the 20 degrees C room temperature that we all want to achieve in our homes. The difference between the two is 80-20 = 60 ie Delta 60


Some boilers have a lower output temperature - if this is the case you may need our Delta 50 figures, we can provide these for all of our radiators if you call our office.

This image shows the Bentley valve range fitted to our showroom radiators.

The valves are fitted to a Daisy Radiator which is painted in Foundry Grey

We can position the bushes for your valves in any position that you request.

In the Uk we tend to use the bottom two bushes for our flow and return.



Many of our customers abroad specify the configuration to suit there applications - typical scenarios are shown below.
