Terma aims to think differently when conceiving its radiator designs and the Rolo Room has versatility at its core with how flexible it can be with the different ways it can be installed. Rolo can be installed vertically as an upright radiator or horizontally as an under window style radiator. There is an internal diverter system for your plumber to aid the water flow as required depending how it is installed. Rolo features very large internal holes where the front bare is recessed into the rear bar meaning there are very large internal holes for quick internal distribution of the water for super quick heat up times. Rolo features large, chunky 40mm diameter bars which offer a very high heat output. Rolo Room offers the choice of either side or underside valve entry - so if you are limited in space vertically or horizontally you can tuck away the valves underneath or on the sides, to ensure it doesn't encroach out of the space assigned to it. The Brass colour from Terma has a matt, metallic, smooth texture. This type of colour/finish is unique for electric radiators. Terma offers a 150x50mm colour chip of this finish should you wish to see the colour prior to purchase. Rolo is part of a unique family of products where you can buy matching radiators (electric and central heating), mirror radiators and towel rails.
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.
