What Is Straight Manual Radiator Valve?

Straight radiator valves are used to connect radiators to hot water pipes on a central heating system. Inline radiator valves have connection points that run parallel or "linear" to each other and should be used when a radiator's entry point is parallel with the pipework. In a manual radiator valve system, the radiator control is down to the thermostat, located elsewhere and of the radiator body.

Feature of Manual Radiator Valve

Manual Control

Radiator valves typically have manual controls that allow users to adjust the flow of hot water or steam to the radiator. This control can be in the form of a simple knob or lever.

Thermostatic Control

Thermostatic radiator valves (TRVs) include a temperature-sensing element that automatically adjusts the flow of water based on the ambient temperature of the room. This feature helps maintain a consistent temperature and can contribute to energy efficiency.

Temperature Setting

Many radiator valves, especially thermostatic ones, have a temperature setting or dial that allows users to set the desired temperature for a specific room. This helps in achieving individualized comfort.

Frost Protection

The radiator valves come with a frost protection feature. If the temperature in the room drops to a level that could cause freezing, the valve may automatically open slightly to allow a small flow of warm water through the radiator, preventing freezing.

Lockable Controls

To prevent unauthorized adjustments or tampering, some radiator valves have lockable controls. This feature is particularly useful in public spaces or in households with children.

Integrated Bypass Function

In hydronic heating systems, radiator valves may include an integrated bypass function. This allows a controlled amount of water to bypass the radiator, promoting proper system balance and preventing issues like overheating.

Compatible with Smart Thermostats

Some modern radiator valves are compatible with smart home systems and can be integrated with smart thermostats. This allows for centralized control and monitoring of the heating system.

Variety of Designs and Sizes

Radiator valves come in various designs and sizes to match different radiator styles and installation requirements. Common types include straight, angled, and corner valves.

Straight Manual Radiator Valve: Everything You Need to Know!

Radiator valves are what you see at the bottom of a radiator - they will have a twisting mechanism on top. They allow you to control how much heat you want your radiator to give out, just like a tap to control the flow of water.

Each radiator will have two valves. One will control the amount of hot water that enters the radiator and the other will balance the system by controlling how much heat comes out of your radiator. This is known as the "lockshield valve".

Manual Radiator Valves

The most common type of radiator valve is a manual radiator valve. The clue to how manual valves work is in the name - you have to turn them to control the temperature.

They work just like a tap, by altering the flow of hot water from the boiler into the radiator. The higher the level on the valve, the higher the volume of hot water entering the radiator to produce greater heat. Once a room has reached the temperature you want, you will need to turn the valve down yourself to a cooler setting.

02.

Thermostatic Radiator Valves

Thermostatic radiator valves (TRVs) give you much more control over the temperature in your home because they have more advanced features. Like a manual valve, you can set the valve to what temperature you'd like a room to be.

The thermostatic valve 'senses' the temperature in your room and once the temperature you want is reached, it will automatically stop the flow of hot water to your radiator and prevent it from getting any warmer, wasting heat and energy.

How to Fit a Straight Manual Radiator Valve

Step 1: Switch off your heating system and shut off the water

Before you change the radiator valve, you'll need to switch off the heating system and water supply. This means that water can no longer enter the. Without doing this, the boiler could overheat.

Step 2: Locate the drain-off valve

Once complete, you'll need to drain your central heating system. Locate the drain-off valve. Connect a hose to the drain-off valve and position the other end of the hose to allow water to run into an outside drain.

You'll then need to wait for the water to drain completely from your radiator. This can take up to 10 minutes.

Step 3: Remove the old radiator valve

To do this, undo the top nut on the existing valve and then spin the bottom nut. This will allow you to remove the valve entirely. Water can sometimes run out at this point, so have a towel ready.

Step 4: Fit the new radiator valve

Fitting the new radiator valve will vary depending on the fitting and type you're installing. Because of this, it's best practice to follow the manufacturer's guidelines on how to fit the radiator valve.

Step 5: Turn on the water mains

Once you've installed your new radiator valve and tightened everything up, it's time to turn the water mains back on. This will refill the system, so keep an eye out for leaks at the new joints. Once refilled, open the new valve to allow water to flow into the radiator.

Step 6: Bleed the radiator

Once you're happy there are no leaks, open the bleed valve to let out any trapped air. Trapped air can prevent the radiator from filling with water, so this is an important step to get the most out of your heating system.

Step 7: Turn on the boiler

Get your boiler back up and running again. Once your heating system has had time to warm up, look at the radiator one last time to ensure there are no leaks and that the radiator is working as it should.

FAQ

Q: What is a manual radiator valve?

A: Manual radiator valves are angled taps that you can find at the side of your radiator to turn the radiator off and on.
The manual radiator valve is possibly the most simple to operate as well as being the most common type. Depending on how warm or cool you require your room to be, you can easily turn them up and down.

Q: How do manual radiator valves work?

A: Think of manual radiator valves like taps: turn the head anti-clockwise to turn it on and clockwise to turn it off. This adjusts the amount of hot water flowing through the radiator, which dictates how much heat is emitted into the room.

Q: What are the benefits of manual radiator valves?

A: The manual valve is also often cheaper to install than TRVs and can give you more focused control over your home heating system. You can tailor your manual valves to different temperatures in each room throughout your home. This is particularly the case when you're heating your entire house but want rooms at different temperatures.
For example, the temperatures of the kitchen and bathroom may need to be different from those of the living room and bedroom because you need to consider warmth and humidity from cooking and washing. Some rooms may not need any heating at all, so manual valves give you the freedom to micromanage your home ecosystem.

Q: Should the radiator valve be open or closed?

A: Most radiators have two valves, one that lets the water into the radiator, and one that allows the water to be removed from the radiator. Familiarise yourself with both valves and their operation. Both valves should be turned fully open (anti-clockwise) so that the water can flow freely through the radiator.

Q: How do you use a manual radiator valve?

A: A manual radiator valve can be controlled and turned by you to the temperature you want, just like a tap. Turn it one way to increase the temperature, and the other way to cool the radiator down. Once the room has reached the right temperature, you can manually turn the valve back down.

Q: Should both radiator valves be fully open?

A: You might think that all valves on all your radiators should remain fully open all the time to allow the free flow of water. However, while this sounds good in theory, this could lead to an imbalance in your heating system whereby some radiators get hotter than others.

Q: What is a manual valve?

A: Manual valves are fixed devices that are installed to begin/control/end the flow of liquids and are usually installed in industrial areas across the world. These valves require human intervention to be controlled thus the word manual.

Q: Can you open a radiator valve too much?

A: Thermostatic radiator valves with too much flow may not operate properly and can be noisy with water "streaming" noises through the valves, particularly as they start to close when the room temperature increases. What causes an unbalanced system? One cause is radiators being removed for decorating and then refitted.

Q: Why is my radiator valve turning off but still hot?

A: If the diverter valve is stuck or faulty, it may not be able to fully close, allowing hot water to continue to flow into the radiator even when the heating is switched off. This can cause the radiator to stay hot. Fortunately, a faulty diverter valve can be easily fixed by a Gas Safe heating engineer.

Q: What do the radiator valve settings mean?

A: Radiator valves have numbers or symbols to represent how much heat the radiator is putting out. Normally, these numbers range from 1 - 6. Turning the valve to 3 should give you a room temperature of around 20°C. Each number above or below then represents a single degree.

Q: Is it bad to turn off the radiator valve?

A: How to turn off a radiator with a manual valve. It is important that you do not turn this fully off, as doing so can result in the water inside the radiator and return pipes freezing, and causing a rupture.

Q: Why do radiator valves get stuck?

A: The valves incorporate a pin that opens and closes regulating the flow of hot water to the radiator and regulating the temperature in the room. The pin does get sometimes stuck it's very common when the heating hasn't been turned on for a few months.

Q: How long should a radiator valve last?

A: approximately 10-15 years
Generally, standard TRVs have an average lifespan of approximately 10-15 years. After this time, the plastic will naturally harden and become brittle, and a slight knock could break the flow control from the body of the TRV.

Q: Why do radiator valves stop working?

A: A sticking valve is probably the most common issue you may encounter with thermostatic radiator valves. You may find that it is stuck open or closed. You usually find a TRV becoming stuck after a long period of not being adjusted, either after a long, cold winter or a long, hot summer.

Q: Are all radiator valves the same?

A: Radiator valves come in all shapes and sizes. You now have a huge choice between thermostatic or manual, vintage-style or modern, angled or straight. You can even go for smart radiator valves to create a WiFi-connected heating system.

Q: How do you control radiator heat?

A: Common places for a thermostatic valve include the base, near the floor or on the top on the left side. You know you've found it when you see a knob with numbers on it. Turn the knob to adjust the heat setting. If it's too hot, simply turn the setting down.

Q: How do I know if my radiator valve is broken?

A: If it is hard to move or you can hear a slight whirring noise from the valve then it is either not functioning properly or not being called to open when it should be.

Q: Do all radiators have valves?

A: It's worth noting that if you buy a new radiator they will not normally come with valves. This is because you need to pick the radiator valve to suit your own individual pipework. Often, people forget that both a lockshield valve and a manual or TRV valve are required, for each new radiator.

Q: What are smart radiator valves?

A: Smart thermostatic radiator valves (Smart TRVs) are devices that were designed to provide individual, room-by-room heating control, by working in conjunction with your thermostat kit and creating a so-called zoned heating system, that can be easily managed through an app for smartphones, tablets, or computers.

Q: Which way do you turn a radiator valve to bleed?

A: To bleed the radiator, turn anticlockwise to open the valve, and clockwise to close the valve. Remember to hold an old cloth or jug under the bleed valve to catch any escaping water. And, turn the heating off before you start.
