Boiler Servicing & Repairs Chelmsford

Boiler Servicing

TM Hughes & Son has been servicing boilers in Chelmsford for over 30 years, ensuring that homes stay warm all year round. Your Boiler works tirelessly to provide heating and hot water daily, and an annual Boiler service is essential to keep it running efficiently and safely while minimising the risk of breakdowns.

Prevent Costly Boiler Breakdowns

Boiler failures are inconvenient at best and unbearable during freezing weather. A yearly service helps prevent such issues and allows our engineers to identify and resolve potential problems before they become costly repairs.

Maintain Valid Home Insurance

Regular servicing also validates your home insurance for Boiler breakdowns—many policies require proof of annual maintenance to remain valid.

Protect Your Family and Save on Energy

Boiler servicing protects your family by reducing the risk of carbon monoxide poisoning. After a professional service, your Boiler will run at optimal performance, providing optimal heat and ensuring you get the best value from your energy bills.

Professional, Accredited Engineers

When you book with TM Hughes & Son, you can expect a friendly, professional service delivered to the highest standards. As Worcester Bosch Accredited Gas Engineers, we combine expertise with care to ensure your heating system is safe, efficient, and reliable.

The Boiler Service

When one of our heating engineers visits your Chelmsford home, they will turn up at the agreed time. Engineers will show you their Gas Safe Registered ID card before starting work. We follow a strict procedure when it comes to servicing Boilers.

1. The Boiler case is removed from the Boiler, and signs of leaks or corrosion are checked. Sometimes, the Boiler case can corrode due to leaking water and condensation. In the event of a corroded casing, we will always attempt to source a new case. Leaks in Boilers usually occur due to old, corroded seals or failed pressure valves. (often caused by too much pressure in the system). We carry many parts in stock to change a seal or valve if a leak is present. We will also check all pipework to ensure no leaks are present.
2. Every boiler seal is checked to ensure they are tight.
3. Waterflow is checked to ensure your Boiler is running at the correct pressure. Sometimes, blockages in the system can restrict water. This can cause your boiler to switch off repeatedly.
4. The Boiler and components are thoroughly cleaned. Cleaning helps your boiler run smoother. Allowing us to perform the required tests accurately.
5. The gas burner pressure is checked. If the burner pressure is incorrect, it’s adjusted as required.
6. A gas rate check is conducted using a gas meter. The gas rate checks determine whether your boiler is burning the correct amount per hour.
7. A flue gas analysis check is run. The flue gas analyser is placed in the flue, measuring the amount of oxygen, carbon dioxide and carbon monoxide. The flue gas analysis will determine whether your boiler is safe and efficient.
8. Ventilation’s checked. Ventilation is important for boilers to work properly. For every cubic meter of gas, 10 cubic meters of air are required for complete combustion. Proper ventilation prevents carbon monoxide poisoning. Our engineers will ensure your ventilation is adequate.
9. The Boiler Flue’s checked. The Boiler Flue allows all exhaust gases from your boiler to escape outside. Improperly set flues can enable household heat to escape as well. Unnecessary and a waste of money. We will ensure your flu is in good working order. Expelling all noxious gases while retaining valuable heat.
10. All Boiler safety devices are checked to ensure they work. Your boiler has safety devices built in, such as safety and relief valves. These are all checked to prevent any potential boiler damage in the event of failure.
11. The Boiler and pipework are checked for leaking gas. Leaking gas can be fatal. But don’t worry. Everything’s checked to ensure no leaking gas from your boiler or pipes.
12. Once the service is complete, your boiler’s switched on. Our engineers will check that all your radiators are heating up. If your radiators are not getting hot at the top, you may have too much air in the system. We can bleed your radiators if necessary. Sometimes, radiators build up sludge and debris. Preventing radiators from getting hot in the middle and bottom. We may recommend a power flush if we find this is the case.
13. We will check your outdoor pipes and make sure they’re not prone to freezing. In winter, frozen water expands and may split uninsulated pipes—a common cause of boiler breakdown. We will make recommendations on any pipes that are not lagged and could freeze.
14. A service record’s written for you. The record will prove your Boiler has been serviced professionally.

Boiler Repairs

• No Call-Out Charges
• Good Prices
• Same Day

Boilers have a lifespan of around 10-15 years. Over this period, your Boiler has worked hard to supply you and your family with hot water. Therefore, boilers break down from time to time. Even those that are serviced every year.

TM Hughes gas engineers are fully qualified and have over 30 years of experience repairing broken-down boilers in Chelmsford homes.

Boiler breakdowns can be very unpleasant, especially in the depths of winter. But don’t worry, if there is a Boiler breakdown, our local heating engineer can be with you within two hours. Your boiler will be up and running swiftly and in good working order.

You won’t get stung on the price either. We have no call-out charges. We make sure our customers are always happy with our fair prices.

Rates are often reviewed to ensure this. TM Hughes & Son engineers are gas safe registered and Worcester Bosch accredited. We issue free no-obligation quotes. We’re qualified to repair many boiler parts.

We carry Boiler parts in stock and can source most other components on the same day if necessary.

Boiler Repairs We Undertake In Chelmsford

There are many reasons why a Boiler breaks down. Over the years, we have seen them all.

If your Boiler breaks down, ensure a qualified gas engineer looks at it. Interfering with a Boiler and central heating system is dangerous. And it can cause unnecessary damage, making your problem worse.

Here are some of the common Boiler Repairs we undertake in Chelmsford.

Kettling

Over time, sludge and limescale can build up in a Boiler. This issue’s called kettling. This unwanted buildup blocks the water flow inside the heat exchanger.

The heat exchanger then overheats, creating loud noises in your boiler and pipes. If left alone, kettling can cause the Boiler to fail, so a new heat exchanger is required.

If you’re suffering from loud noises in the system, it’s best to get your heating system power flushed. Before any damage is done, it shortens the lifespan of your boiler.

Leaking

Never ignore a leaking Boiler. Leaks can cause your boiler to short-circuit and fail. Leaking water from Boilers can also cause water damage elsewhere in your home.

Usually, a leaking Boiler is fixable by replacing a faulty seal or pressure valve. Too much pressure in your system can cause a valve to fail. If so, our engineer will set the correct system pressure for you once the valve is repaired or changed.

It’s prevalent for a pump seal to wear out, causing leaking. Changing the pump seals is a common boiler repair job. Sometimes old Boilers leak around the pipes. This could be due to improper fitting or corrosion.

Boiler Keeps Switching Off

If your Boiler keeps switching off, it could be due to low pressure. If low pressure is the issue, repressurising the boiler to the correct pressure can sometimes be enough to fix it.

Otherwise, a blockage in the system could restrict water flow. An obstruction will need to be removed.

A blocked or failed pump can cause low pressure, making the Boiler switch itself off. In this case, the pump will need to be looked at.

Old Thermostats

An old, unreliable thermostat can cause Boiler issues. Your Boiler could be in full working order, but the thermostat is inaccurate or has failed, preventing your Boiler from working. If your thermostat is the cause, a new one will fix your Boiler issue.

Pilot Light Keeps Going Out

Your Boiler will stop working if the pilot light isn’t on. If your pilot light keeps going out, the first thing to check is the gas supply. It won’t stay on if enough gas doesn’t reach the Boiler.

The main cause of an extinguished pilot light is a malfunctioning thermocouple. Stopping gas from entering your Boiler. One of our engineers can change a faulty thermocouple for you.

A new thermocouple ensures enough gas gets to the Boiler, and the pilot light isn’t blown out. So your Boiler will run all the time.

Low Pressure

Your Boiler and central heating system require some pressure to operate. If the pressure is absent, your Boiler won’t work.

A leak in the system can cause low pressure, and so can a faulty pressure relief valve. A leak in the system can be nasty.

Water damage to your home could occur. One of our engineers will identify a leak in the system or a faulty valve. Getting your pressure back up to where it needs to be.

Unusual Noises

Unusual noises in your Boiler or central heating system need to be looked at upon discovery. These noises can indicate a fault in the system, such as failing pumps, too much air, or low pressure. It’s best to examine these faults before they become serious issues.

Condensate Pipe Frozen

The wastewater from the modern condensing Boiler is expelled outside via a condensate pipe. These pipes should be insulated to prevent freezing in winter. A frozen and thus blocked condensate pipe can stop your Boiler from working. Frozen pipes need defrosting.

Radiators are not heating up.

If your Boiler’s not working, your radiators won’t heat up. If your Boiler is working and your radiators are not heating up, you have one of two issues.

• If there’s too much air in the system, heat isn’t distributed around the radiators as it should be.
• If the radiators are only getting hot at the bottom, the system has too much air.

A simple bleed will remedy this. You can do this yourself, or one of our engineers will gladly do it for you.

If your radiators are cold at the bottom and middle, you likely have a sludge buildup in the system. A power flush will get your system back to full working order.

Boiler Breakdown Prevention

Boilers work pretty much every day of the year. Boilers must be well-maintained if you want them to last and not let you down. An annual Boiler service will minimise the risk of a Boiler breakdown.

Insulating vulnerable pipes in cold areas will prevent freezing problems. (which can lead to boiler breakdowns in winter). If you suspect a fault in your central heating system, call us. We will be more than happy to check your Boiler and system for you.

Boiler and central heating issues will never repair themselves. Left alone, issues can become more severe and expensive problems that may write off the Boiler, requiring a new one.
