These valves have a 1/2" BSP radiator connection and so will fit all radiators and towel rails in the UK. The other connection to consider is that of your pipework, these valves have a 8mm pipework connection (usually termed “microbore” pipework) and so will fit pipework of the same size. We have these valves available in 15mm and 10mm for those with standard (15mm) or larger microbore (10mm) pipework.
Fitting TypeStraight valves are the ideal valve for older homes built before the modern home building styles of today. These are a simple but true saviour to bring older homes into the modern era, and not to be underestimated. Straight valves are used in the following set ups:
- Pipework comes from the floorboard up to the radiator, and the radiator connection is on the bottom.
- Pipework that runs along the wall or skirting board and the radiator has connections at the side.
- Pipework comes out from the wall and bends up and the radiator connection is on the bottom.
- Pipework comes out from the wall and bends round and the radiator has connections at the side.
Thermostatic Radiator Valves, otherwise known as TRVs, provide multi temperature control of the radiators in your home – saving energy and money! These valves have liquid sensor mechanisms inside that shut off the flow of hot water to the radiator when the room temperature reached the desired level (which you set using the number dial on the TRV head). All of our Thermostatic radiator valves come with frost protection mode, which automatically opens the valve a little bit, even when fully switched off if the temperature of the room drops below a certain level – preventing your heating system, radiator and pipe from damage caused by frozen water.
MaterialThese valves are made from high quality brass, which means they are strong and durable and will look great on your radiator or towel rail for years to come!
Don’t forget to add some matching pipe covers to your basket to complete the overall look and hide unsightly pipework!
StyleModern radiator valves offer sleek style to suit new and existing radiators in homes with modern décor.
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
