Would you like a Celsius plumber to fit a new radiator in Edinburgh?

Fitting new radiators?

Sometimes, due to age, replacing existing radiators is the best option – and that gives you the choice on whether to replace ‘like for like’ of whether you’d like a lovely new designer radiator or perhaps a more traditional cast iron radiator.

You should always consider the size and BTU requirements as well as design preferences/style when selecting a new radiator for your home.

Fixing radiator leaks before they damage your carpet or floor.

Repairing radiator leaks?

Typically radiator leaks are caused by corrosion or a faulty valve.

A Celsius plumber can help you fix a leaking radiator.

Identifying the leak source is crucial and, depending on the issue, parts might need replacing.

Radiator leaks are often caused by corrosion.

Corroded radiators?

A common issue with ageing central heating systems, is corroded radiators.

Addressing this promptly by replacing the corroded radiator can prevent leaks and more costly fixes.

If your central heating radiators are starting to rust badly, then that is a sign of a potentially bigger issue.  Please let Celsius know if you’d like a central heating chemical flush or even have a look at our range of new central heating boilers.

Radiator valve replacements?

Valves control the amount of hot water entering the radiator.  Faulty valves can lead to inefficiency, requiring either repair or replacement.

Balancing radiators ensures an even distribution of heat and maximum comfort.

Balancing radiators?

Ensuring an even distribution of heat across all radiators in a home ensures efficiency and comfort.

This often requires adjusting valves on each radiator.  A professional plumbing firm like Celsius can ensure that your heating system is effectively and properly heating all the radiators throughout your home.


Bleeding radiators to reduce the trapped air that causes cold spots.

How much does it cost to repair a radiator?

Radiator repair costs can vary based on the issue.  On average, a professional plumber might charge around £100 for a repair visit.  If a repair is going to be more involved, then ask for a quote to be sent to you before proceeding with any works.


How much to install a new radiator?

The costs to install a new radiator can vary depending on the type of radiator you’d like installed and whether it is going to be fitted in the same location (it should be cheaper as there should be less need to lift floors and adjust pipework).  On average, a good plumber might charge around £80-100 per hour to install a replacement radiator.

If, for example, you are adding a second radiator to a colder room in the house then it is likely to take longer as we will have to lift floorboards and fit new pipework.


What tradesperson fixes or replaces radiators?

Normally a plumber or heating engineer.  However smaller radiator repairs, like bleeding a radiator, can be carried out by confident DIY’ers that have the correct tools and know what they’re doing.

“Engineer arrived at booked time for my radiator replacement, calling ahead half an hour before arrival. Work done, and old radiator removed, with no problem.”

Why is my radiator cold at the bottom?

This usually indicates a build-up of sludge or rust inside your radiator, it’s a common sign of a central heating system not being maintained properly over many years.  It can be resolved by flushing the radiator system and pipe work, adding cleansing chemicals and or installing a magnetic system filter.  Sometimes if the system is really badly corroded, then the entire system needs to be replaced.

Ask a plumber to attend and bring a thermal imaging camera with them to properly investigate the sludge / rust issues you are experiencing, it’s a really simple, accurate way to identify the issues and will give you a better idea of what the repair works are likely to cost.

Can I paint my radiator?

Amazingly this is a question we get asked a lot.  Yes, but it’s essential to use radiator paint to ensure your radiator heating performance isn’t affected.

Why is my radiator making a noise?

Noises can be due to trapped air, radiator valve issues, or pipe expansion and contraction.  Regular maintenance or bleeding your radiator can typically resolve this.  The cost to get a good plumber to visit your home and resolve matters can start at around £100.

What is a TRV on a radiator?

A TRV, or Thermostatic Radiator Valve, is a type of radiator valve that is often fitted to radiators in central heating systems.  Here is everything you need to know:

1. Function: The primary function of a Thermostatic Radiator Valve (TRV) is to regulate the temperature of a room by adjusting the flow of hot water to the radiator.  It does this by sensing ambient air temperature around the valve.


2. Components: The TRV typically consists of two main parts:

The Head: This contains a temperature-sensitive element (usually a wax or liquid) that expands or contracts as the surrounding temperature changes.

The Valve Body: This is the part connected to the radiator and the pipework.  The expanding or contracting element in the head operates a pin in the valve body to open or close the valve.  It is quite simple really, but really good to have fitted to your radiators.


3. Operation: You can set a TRV to a desired room temperature, typically marked from 1 (coolest) to 5 (warmest) or sometimes even more detailed with actual temperature figures.  When the room temperature exceeds the set level, the valve will begin to close, reducing the flow of hot water into the radiator and thus reducing the room’s heating.  When the room temperature falls below the set level, the valve will open, allowing more hot water into the radiator and increasing the heat output.


4. Benefits:

Energy Efficiency: By regulating the temperature in individual rooms, you can avoid overheating spaces that aren’t in use, saving money on your energy bills.

Comfort: Allows individual rooms to be set at different temperatures based on preference and usage.

Cost-effective: Installing TRVs is a relatively inexpensive way to gain better control over your heating system and as we stated previously, which can lead to reduced heating bills.


5. Limitations: TRVs should not be fitted on radiators in rooms with a wall thermostat.  This is because the wall thermostat should control the boiler’s operation, ensuring that the room it’s in reaches the desired temperature ( normally your hallway).  If a TRV were to restrict the flow of hot water to the radiator in this room, it might cause the boiler to overwork, making your energy bills higher and your home too warm.

When using TRVs, it’s also essential to ensure that they are not obstructed (for instance, by furniture or curtains), as this can prevent them from accurately sensing the room’s temperature.  If you have wooden radiator covers in your home, check your radiators don’t have TRV’s installed, because if they do, it could mean your room is not heating as efficiently as it should be.


Why leave one radiator without a TRV?

Leaving one radiator without a Thermostatic Radiator Valve (TRV) ensures that there is a continuous flow path for the water in the central heating system.  This is known as your “bypass” radiator and it prevents the boiler from becoming damaged due to excessive pressure or overheating when all other TRVs are closed because your rooms have reached the desired temperatures.

Additionally, the bypass radiator helps maintain system pressure and reduces the risk of noise from water boiling within the system.  It is also a requirement of your boiler installation instruction and may invalidate any warranty if not fitted.  Your bypass radiator would be installed with manual ‘non thermostatic’ radiator valves.


Why is it important to maintain your radiators?

Ensuring your radiators are in top condition is really important, but why?

Energy Efficiency:

Efficient radiators ensure that your home heats up quickly, using less energy and in turn, saving on those hefty heating bills.

Preventing Damage:

A faulty radiator can lead to leaks, potentially causing damage to your property.

Optimal Heating:

A well-maintained radiator ensures consistent heating throughout your home, ensuring comfort for everyone and lower energy bills.

Prolonged Lifespan:

Regular maintenance can increase the lifespan of your radiators and heating system as a whole.

Health & Safety:

A faulty radiator can lead to dampness, promoting mould growth which is harmful to health. Radiators falling off walls are common, as people sometimes like to lean on radiators, but overtime this weakens the screws that support the radiator.
