Terma aims to think differently when conceiving its radiator designs and the Harley features diamond shaped bars formed in ever decreasing right angle profiles - creating a unique linear design which differs from standard bar design radiators. Angus is finished in a square profile frame - making it appear like a piece of art on the wall and will look equally as effective in a bathroom or standard room of the house. The brackets on the Angus are a matching colour and style helping to achieve a look as if the radiator is simply floating. The RAL 5009 Azure Blue colour from Terma has a silk, smooth texture. Angus features underside entry points for the valves meaning these can be tucked underneath out of the way and won't stick out on the sides like ears. Good if you have limited width in which to install the radiator.
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.
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.
