Terma has invested in pipe bending technology which allows it to produce heated towel rails such as the Warp S. Warp S is designed with large flat bars which sweep forward and then bend backwards on themselves to create a towel rail which is only mounted to the wall on one side, leaving the other side open and free for easily hanging towels on. Warp S can be mounted either way up as it has symmerical bars top and bottom, so the horizontal bars can reach out to the left or right hand side as you prefer. Think about where the towel rail will be placed in your bathroom in relation to the walls and which side of the towel rail provides easier access. Warp S has a very free floating effect as there are minimal brackets on show and it is free from obstruction for hanging the towels. Warp S has a large surface area in comparison to lots of standard ladder type rails - this means you get a higher heat output and additionally the colour stands out a lot more as a feature in the bathroom, on this basis Terma offer the Warp models in a range of very eye catching colours. Warp S 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 (1110h = 800w, 655h = 400w element) The Soft RAL 9005 black colour has a super matt, smooth textured finish. Terma offers a 150x50mm colour chip of this finish should you wish to see the colour prior to purchase. Warp S features 50mm pipe connections so we suggest matching this with a 50mm H block valve which will provide a neat finish.
*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.
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.
