Towel rail radiators are a valuable addition to any bathroom.
Like all types of towel rail radiators, they can encounter issues, but fortunately, most problems are relatively simple to resolve.
In this Bathroom Takeaway guide, we’ve gathered together many of the reasons why your towel radiator isn't working and what you can do to fix it!
How To Identify A Towel Rail Issue
If you’re thinking ‘how do I know if I have an issue with my towel rail?’ There are a few reasons why it may not be working, so let’s take a look at them.
Valves Are Closed Or Seized Up
It could be that your valves are closed or seized up, to check this you need to assess the valves on either side of the radiator to check if they are fully open.
If it is established that the valves are open, the internal valve pin may be stuck.
Prolonged inactivity of the heating system can lead to the valves seizing, and accumulation of paint, dust, or debris may also contribute to this issue.
A Blockage In The System
Over time, older towel radiators may experience blockages due to the buildup of sludge, limescale, and debris.
Obstructions like this in your system can lead to inadequate heating or only partial heating of the towel radiator. It is also possible, though less common, for blockages to occur in the valves or pipes.
The Towel Radiator Needs Bleeding
Most radiators typically require bleeding on an annual basis.
This process entails the removal of small amounts of trapped air that may hinder the radiator's efficiency.
Generally, bleed valves are situated in the upper corner of the radiator and can be operated using a bleed key or a screwdriver.
Flow And Balancing Issues
Heating systems must effectively distribute warm water to every radiator within a household, but they can sometimes become unbalanced.
This imbalance may lead to your towel radiator heating slowly or not reaching its full temperature potential.
To assess whether a balancing issue exists, deactivate all other radiators in your home except for the one in question. If the radiator in question heats up properly when the others are turned off, it suggests a balancing problem.
How To Fix A Heated Towel Rail
Now you have an idea of what the problem is with your towel radiator let’s find out how you can fix them.
Fixing Solution 1 - Rebalance Your Heating System
If you notice that your towel radiator is heating up slowly or not reaching its full temperature, it is advisable to switch off the other radiators.
This will help you ascertain whether the problematic radiator can function effectively on its own. Should it heat up adequately, consider rebalancing the entire system.
Fixing Solution 2 - Removing Blockages
Obstructions can develop in numerous areas, such as the valve, plumbing, or within the radiator itself. If you notice that the top of your radiator is heating properly while the bottom remains cold, it may be advisable to flush the radiator.
While a DIY flush is feasible, a more extensive flush should be undertaken only with the guidance of a heating engineer.
You also may wish to disassemble the valves to inspect for sludge accumulation, making sure to shut off the water supply prior to this procedure.
Fixing Solution 3 - Fixing closed or seized up valves
Should your towel radiator be newly installed or if you have recently modified the valve settings, it is important to verify that the valves are sufficiently open.
It is possible for the valves to appear normal externally while being seized internally
Fixing Solution 4 - Bleeding Your System
If your towel radiator has been newly installed or if you have recently adjusted the valve settings, it is essential to ensure that the valves are adequately open.
Valves may seem operational from the outside, yet they could be stuck internally.
Take a bleed key or screwdriver and gradually loosen the valve until you hear the sound of air rushing out. Be prepared for potential water leakage, and consider placing a towel on the floor to catch any drips.
After the radiator has stopped releasing air (and not water), make sure to close the valve securely.
In the event that a significant volume of water is lost during the bleeding process, it could be required to refill the system to ensure adequate pressure levels.
FAQ’s
How To Fix Electric Heated Towel Rails
If your heated towel rail is not working, start by checking the thermostat.
Ensure that it's set to the desired temperature and functioning correctly. If the thermostat seems to be working fine, the issue may lie with an airlock in the system.
How Do You Adjust The Temperature Of A Heated Towel Rail?
The temperature of your heated towel radiators can be regulated or changed using either manual or thermostatic valves.
To decrease the heat or deactivate the unit, rotate the manual or TRV valve in a clockwise direction.
To enhance the heat output or activate the unit, adjust the valve accordingly.
How Long Should A Heated Towel Rail Last?
On average you can expect a towel rail to last up to 10 years.
How To Fix A Leaking Heated Towel Rail?
If you are wanting to know how to fix a leaky heated towel rail you may need to consider tightening the gland nut to see if this action halts the leak. If the leak persists, it would be prudent to remove the nut, wrap PTFE tape around the spindle, and then retighten the gland nut.
Can You Fix Heated Towel Rail To Floor Pipe
Yes, it is essential to have different valves installed at the bottom. These valves will connect to the wall and must be straight. If these specific valves are not available, the situation may become very challenging. You may also need to reposition the pipes based on the width and location of the new towel rail in comparison to the old one.
