Are All Radiator Valves The Same Size

Are All Radiator Valves The Same Size

In the UK, the BSP standard for radiators requires a 15mm entry at each end. This means that regardless of the size or style of the radiator, the valve will always be of the same size.

Indeed, in the UK, the BSP (British Standard Pipe) norm stipulates that all radiators must have a 15mm entry at both ends, regardless of their size, shape or design. This requirement ensures that the corresponding valves for the radiators are always standardized and compatible.

What size radiator valve do I Need?

The size of a radiator valve can depend on aesthetics and type, but in terms of fitting sizes, the width of the connections is measured in millimeters. The most common valve size is 15mm as it fits with the most commonly used 15mm copper pipes.

What are the different types of Radiator Valves?

One of the most common types of radiator valve is the corner valve, also known as flat front valves. These valves are often chosen for their decorative appeal and do not protrude as much as angled valves. Corner valves are angled valves with their tops facing inwards and parallel to the wall.

Do radiator valve replacements go into the radiator?

The replacements for the radiator fit well, but they do not screw onto the existing valves properly as the thread catches and only does one full turn, even with a spanner. The user is questioning the size of the radiator valve thread.

Is the radiator connecting part and nut bigger than the valve's thread?

The radiator connecting part and nut are slightly bigger than the existing valve's thread and the lockshield side too, causing a mismatch. The author wonders if they need to replace the valve or if there is an adjuster they can buy since the size difference is only a few millimeters. They also express concern about having to empty the system if they opt for replacement. This issue was discussed on the Screwfix Community Forum.

The BSP standard in the UK requires radiators to have a 15mm entry at both ends which is a standardized threading size for valves and is part of the British Standard Pipe industry-wide standard.

What are the common BSP thread sizes for cast iron radiators?

The common BSP thread sizes used with cast iron radiators include 1/8", 1/4", 3/8", 1/2", 3/4", 1-1/4", 1-1/2" with their corresponding actual outside diameters in millimetres. To find the right size, you can measure the actual outside diameter of a valve tail, threaded nipple, reducing bush or an opening in the radiator.

What size is a radiator Spanner?

The radiator spanner is a 1/2 inch BSP size and is used for installing or removing the tails of union type radiator valves. It is made from high tensile steel and has a length of approximately 135mm. This tool is commonly used in the installation of thermostatic and manual radiator valves.

What size is a thermostatic radiator valve?

A thermostatic radiator valve typically has a 1/2 inch BSP female threaded connection for the valve. The Myson TRV2 2 Way valve has a 15mm size and also a 1/2 inch BSP threaded connection for the radiator. A replacement head is also available for the Myson TRV2 valve. For more information on plumbing thread sizes, the BSPT link at the bottom of the page can be consulted. Stevenson Plumbing offers various types of radiator valves including thermostatic and manual options.

What is the difference between NPT and BSP?

NPT and BSP are two different types of thread systems used in piping and plumbing. The key difference is in their thread angles, with NPT having a 60º angle and BSP having a 55º angle. They also have different numbers of threads per inch at most sizes, except for ½" and ¾". It's important to know which thread system is used in order to find the correct thread size for fittings and connections.

How to replace radiator valves?

To replace radiator valves without draining the system, start by covering the surrounding floor area with towels and a container to catch excess water. Then prepare the on/off radiator valve on the flow pipe and remove the thermostatic head from both valves if swapping an old thermostatic valve for a new TRV.

How does a thermostatic radiator valve work?

A thermostatic radiator valve can be installed to regulate the temperature in a room. The valve senses the room temperature and stops the flow of steam through the supply pipe once the desired temperature is reached to prevent overheating.

What are the benefits of updating your Radiator Valves?

Updating your radiator valves can improve your home heating and decor. Replacing a faulty radiator valve is necessary to prevent problems with the heating system. Additionally, the system can be changed without the need to drain it, making the process easier and more efficient.

How long does it take to replace a radiator?

Replacing a radiator can take most of a day, but it is doable with care and patience. The process involves draining the old radiator, detaching any parts keeping it in place, removing it, installing a new radiator, re-installing any removed parts, and adding coolant.

It is recommended to use a 15mm valve for radiators in most UK houses, as it is the standard pipe size. However, it is important to verify the necessary size since other sizes are also available.

What are the different radiator valve sizes?

The most common radiator valve size is 15mm, as it corresponds to the standard size of copper pipes. Other sizes that may be encountered range from 8mm to 28mm, along with accompanying adapters. Radiator valve options vary in design for customers to match their preferred aesthetic.

What are angled radiator valves?

Angled radiator valves are used to join horizontal pipework to the valve inlet of a heated towel rail when the central heating pipes come out of the wall. Standard radiators typically have side inlets, while angled radiator valves are used for this specific purpose.

How do you use a manual radiator valve?

To increase the temperature in your radiator, turn the valve by hand just like a tap. Remember to turn it off afterwards and monitor your heating bills. Ensure you have the appropriate valves for your radiator.

There are typically five types of radiator valves available for use: angled radiator valves, straight radiator valves, H-block radiator valves, corner radiator valves, and lockshield radiator valves. Angled radiator valves are designed to be used where the pipework comes up from below the floor, while straight radiator valves are used when the pipework comes from the wall. H-block radiator valves are used for two-pipe systems, where two radiators can be connected to a single valve. Corner radiator valves are used in situations where the pipework comes up from the floor and the valve needs to be turned at a 90-degree angle. Lockshield radiator valves are used to balance the heating system by controlling the flow of water and balancing the heat output across all radiators in the system.

What are manual radiator valves?

Manual valves and Thermostatic Radiator Valves (TRVs) are used to regulate the heat in radiators. Manual valves are similar to home taps and can be adjusted to control the heat. This information is from Mr Central Heating's guide on understanding radiators and valves.

What is a thermostatic radiator valve?

Thermostatic Radiator Valves (TRV) are automated valves that eliminate the need for manual control and enable users to set their radiators to a specific level. These valves shut off when the desired point is reached to prevent additional water flow into the radiator. They were created to address the drawbacks of manual valve types. The types, functions, working, and buying guide of radiator valves are explained. Overall, TRVs are a convenient and efficient option for regulating the temperature of your home heating system.

What is an angled radiator valve?

Angled valves are recommended for connecting radiator pipes at a 90 degree angle, especially in modern homes with concealed pipework under the floor. Corner valves can also be used depending on the connection angle. This information is provided by PlumbNation's guide to radiator valves.

How to fix a radiator Valve Coupling nut leak?

To fix a leaking radiator valve coupling nut, you can try tightening the coupling or replacing the olive inside. If these steps don't solve the issue, the valve may need to be replaced. Adjust the steps accordingly if you have a grand union type valve.

What does 15mm radiator connector mean?

The radiator connector and nut are too big for the valves and there is confusion about the meaning of 15mm in relation to the fitting size between the radiator and valve. This issue was discussed on Screwfix Community Forum.

Is a bigger radiator better?

In general, a bigger radiator is better for cooling, but it ultimately depends on your situation. Radiator size is determined by thickness and length, both measured in millimeters.
