Terma aims to think differently when conceiving its towel rail designs and the Quadrus Bold has been designed to maximise heat output by having two layers of bars, a full rear layer and forward layer with gaps for towels. The flat bars with closely spaced gap differ from the standard ladder rail creating a fuller looking overall design. The front bars protrude forward from the front of the upright bars and the rear bars are suspended between the uprights which results in a large gap within which to feed the towel. The Metallic Black colour from Terma has a light sparkle to it and has a matt, rough textured finish. Quadrus Bold can also be fitted as dual fuel - whereby it can run on the central heating in the winter and as electric in the summer. You simply need a Terma heating element and the Terma Integrated Valve with Immersion Tube (no T piece required with this valve) to easily install as dual fuel (870h x 450w = 600w, 870h x 600w = 800w, 1185h x 450w = 800w, 1185hx600w = 800w element)- Δ30: 1297 / Δ40: 1809 / Δ50: 2419

*These electric heating elements must be installed by a registered competent electrician. Any faults developed due to incorrect installation will not be covered under the product warranty. The suggested fuse size is calculated based on a 230V supply and whilst 230V is the nominal voltage given to homes in the UK, the actual voltage supply can vary. The registered competent electrician carrying out the installation will determine the appropriate size of fuse to use for the installation.
Delta (Δ) Ratings Explained
What is a Delta (Δ) Rating?
When discussing heat outputs, the Delta rating is the difference between the temperature of the water inside the heating system and the desired temperature of the room.
What does the value represent?
In simple terms, this value is about heat loss. Heating a room only works, if the radiator output exceeds the heat loss of the room.
We use this calculation to make it easy to choose a radiator that will have a heat output that exceeds the heat loss of the room when connected to your heating system type.
If you don't know the room heat loss, you can use our calculator to find out.
What Delta Rating should I use?
- Δ50 = Gas boilers before 2005 / Oil boilers before 2007.
- Δ40 = Gas boilers after 2005 / Oil boilers after 2007.
- Δ30 = Low temperature systems e.g heat pumps.
Watts & BTUs (British Thermal Units) Explained
What is a Watt?
Watts are our main unit of energy/power in the UK, commonly associated with lightbulbs and Home Energy performance certificates (EPCs).
What is a BTU?
BTUs are the unit of measurement used to portray a radiators heat output and a rooms heating requirement. 1 Watt is equal to 3.41 BTUs.
Why are they important?
We buy radiators to heat our homes, right? So, we need a way of knowing if a radiator is powerful enough to heat the room that we are shopping for - Watts and BTUs provide us with a value that makes its easier to compare radiators and ultimately choose the right one for our heating requirement.
Need help figuring out how much heat your room needs?
Our fast and easy-to-use BTU calculator can help you:
- Work out a heating requirement value (in BTUs & Watts) for your room
- Show you in-stock radiator recommendations that can fulfil this heat requirement
