Boiler maintenance is absolutely vital, but it is all too often disregarded by homes in the United Kingdom. Boilers are not only expensive to repair and replace, but when they are not operating efficiently, they will cost you more money to operate and may even endanger the health of your family. Maintaining your unit on a regular basis is critical to keeping it healthy and efficient over the long haul.

In this article, we will give you 10 tips to keep your boiler in great shape for as long as possible.

1 – Service you boiler annually

Having your boiler serviced on at least once a year is the most convenient and effective approach to keeping it in good shape, extend its life, avoid damage, and ensure that it works efficiently. 

A professional service is required to keep the manufacturer’s guarantee in effect. It is has to be carried out by a Gas Safe Registered engineer. They will ensure that all components are in correct working order and that your boiler is safe to use for another year.

Specialists will be able to identify minor concerns as early as possible, before they develop into costly and sometimes deadly problems later on. Don’t hesitate to schedule an appointment with a Gas Safe Registered engineer to get your boiler system tested.

2 – Be on the lookout for Leaks and Drips

Make sure to check for water leaks or drips around the boiler and the pipes very frequently. 

Corroded pipes are more prone to leaking and are the first indication that your boiler may be in need of replacement or repair.

Additionally, if the pressure in your boiler is too high, it may leak, so keep an eye on the pressure gauge as well.

In any case, unless you are a professional, there is nothing you can do to fix a leak or a drip on your own so do not hesitate to ask a professional.

3 – Bleed Your Radiators

Have you ever observed that your radiators are warm at the bottom and cold at the top when you turn them on? It indicates that there is trapped air within, which reduces its efficiency. To address the problem, simply follow these simple steps:

-Protect the flooring with plastic covers to prevent potential stains and water damage.

-Insert the key into the bleed valve and spin it counterclockwise while holding an old piece of cloth underneath to catch any drips that might occur.

-It makes a hissing sound when the air is forced out of the radiator due to the pressure applied.

-As soon as you have expelled all of the air, the hissing will stop, and some water should appear. Make use of the cloth to soak up any water that may fall.

-Close the valve by turning the radiator key in the clockwise direction.

-Your radiator should be warm all the way up to the top at this point.

-Do not forget to check the boiler pressure after you have bled your radiators because it may have cause it to decrease.

It can be difficult to figure out how to properly bleed your radiators when you have never done it before. Make sure to inform yourself before starting anything or ask a professional if needs be.

4 – Make sure the Flue is Accessible

According to regulatory standards, the boiler flue must be made accessible so that cracks or loose joints can be identified. The reason for this is that cracked or loose joints may allow carbon monoxide to seep into your house. An engineer certified by Gas Safe can, however, install flue access panels if your flue is concealed in the ceiling. If your flue is not easily accessible, a Gas Safe engineer will most likely need to build an access panel to allow you to access it.

5 – Balance your radiators

The process of balancing the radiators involves adjusting their valves in order to ensure that warm water is distributed evenly to each one. Frequently, the radiators that are the furthest away from the boiler are the ones that are the coolest.

While it is more difficult than simply bleeding the radiators, it is well worth the effort because it allows the system to heat the home more uniformly. In the case of larger homes, it may be a good idea to seek the assistance of a Gas Safe (Corgi) registered gas engineer.

6 – Re-pressurise your boiler when needed

As soon as the boiler is up and running, check the pressure gauge to ensure that it is within the manufacturer’s suggested limits. Re-pressurise your boiler on a regular basis to ensure that it heats your home evenly and provides enough hot water when you need it.

7 -Check the Flame

As soon as the boiler is up and running, check the pressure gauge to ensure that it is within the manufacturer’s suggested limits. Re-pressurise your boiler on a regular basis to ensure that it heats your home evenly and provides enough hot water when you need it. Work cautiously to prevent causing damage to the boiler and having to pay for costly boiler repairs.

8 – Insulate your pipes

When it becomes cold, your pipes may freeze over, reducing the efficiency of your heating system. Even worse, it can result in a boiler failure. The most effective approach to avoid this is to insulate them, which is lagging.

Lagging is rather affordable and can be found at any local building and DIYing supply store. It is simple to install, as it only requires that you wrap the pipes around the fittings. So do not hesitate to look into it.

9 – Make sure your boiler room is well ventilated

Keep any things and clutter away from your boiler to ensure that it receives enough air circulation. 

Allowing your boiler to breathe is critical to ensuring that it operates properly, as it naturally becomes warm while in operation.

When it’s in an airing cupboard or box, make sure there’s an access panel so you can get to it quickly.

10 – Ensure that your boiler is clean

Boilers need to be cleaned on a regular basis. A well-maintained heating system will assist you in reducing your overall energy consumption costs. It is only when your boiler is clean that it will operate efficiently.

Step 1: Turn the boiler off.

Before you begin, locate your boiler’s main switch and turn it off completely. Then, to avoid burning yourself, allow the device to cool for two to three hours after turning it off. Once the boiler is no longer hot, remove the front and top covers, as well as the vent stack, with screwdrivers or a similar tool.

Step 2: Clean the tubes and boiler unit.

After removing the covers and vent stack, you will have access to the tubes in the heat exchanger, which can be cleaned. Clean the soot, dust, and carbon from the tubes all the way down to the heater’s base with your cleaning brushes. After that, clean the vent stack and then wash the burner tubes with clean water, allowing them to dry between each wash. Once the tubes are completely dry, vacuum the bottom and exterior of the boiler to thoroughly clean the area around it. After that, clear the space surrounding the boiler of any impediments and vacuum off any debris and dust that has accumulated.

Step 3: Reassemble the unit and turn it on once more.

Now that your boiler has been thoroughly cleaned, reassemble the pieces and turn on the system again. Allow for the thermostat to recover to its usual temperature before looking for a blue flame on the thermostat. After that, make sure that the heating system is operating normally.
