What are the 2 valves on a towel radiator?

One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.

What valves are needed for heated towel rail?

Straight valves are the ideal choice for when the inlets are positioned at the foot of the towel rack and pipes protrude from the floor. Angled valves are necessitated should the water require diversion at a 90 degree angle.

What do the valves do on a towel radiator?

What do towel radiator valves do? The valves in a towel radiator control the flow of water through the pipes, ensuring your radiator heats up effectively and efficiently. They keep your towel radiator functioning and ensure that your bathroom is heated up when needed, and your towels are dry and ready to use.

How do the valves work on a heated towel rail?

Thermostatic radiator valves (also known as TRVs) measure the temperature in the room and then adapt the heat output of the radiator. When the room temperature reaches the desired level, the valve closes to stop the flow of water and prevent the radiator from getting any hotter.

Should both radiator valves be open?

You should open both of the valves on all of your system’s radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.

Why is there 2 valves on a radiator?

The reason you need two valves generally on all rads is because the system dictates a flow and return. The flow pipework carries the newly heated water from the boiler. The return taking it back at a lower temperature to be reheated by the boiler.

Do you need a thermostatic valve on a towel rail?

However, it’s always recommended to have at least one radiator in your home to have manual valves, without a TRV. It’s common practise for this radiator (or towel rail) to be in the bathroom. The reason one radiator in your home needs to be TRV-free is as a safety mechanism.

What is the difference between straight and angled valves?

Straight radiator valves don’t incorporate any curves or bends, instead connecting to a bathroom radiator or standard designer radiator up from the floor. Angled valves are usually used to provide a clean finish, concealing pipework and plumbing more effectively than their straight counterparts.

Where are the valves on a towel radiator?

Straight valves should be used when the inlets are at the bottom of the towel rail and the pipes are protruding from the floor. Angled valves will be needed if the water needs to be diverted at a 90-degree angle. This is often the case when pipes and valve inlets are situated at the side of the radiator.

How do you know which is flow and return on a radiator?

Turn off the heating until it is cool. Turn it on and aim the laser alternatively at the two tails. The one that heats fastest/first is the flow.

How do you bleed a towel radiator valve?

Locate the bleed valve which is usually at the top of the towel radiator. Wrap your rag around to make sure you have a good grip. Use your radiator key to turn it anti-clockwise. The air will escape with a hiss and then a small amount of water will come out.
