FAQs

how long does a boiler service take?

How Long Does A Boiler Service Take?

Servicing of your boiler is a very crucial activity which does not only help in keeping your heating system in a top condition, but also assists in ensuring the safety of both you and your loved ones. If you carry out a regular boiler service you’ll be able to identify any possible fault your boiler may have on time before it leads to a more serious issue or even a boiler breakdown. As a result, you’ll be able to save yourself some time and money, but more importantly will save you from any dangerous risk that may result from gas leak in a boiler. The best time for a boiler service is in the summer when you’d probably would not really need the system, so you can take advantage of that as well as the possible lower boiler servicing cost during this period.

Before we look into the amount of time a boiler service should take, let’s first consider what should be done during a boiler service.

✓ Visual inspection. This is a check carried out by the heating engineer to ensure your boiler still meet the existing standards and requirements while also looking for any faults.

✓ Removal of boiler casing. There’s the need to ensure everything is working just fine and also to clean the boiler’s interior. These inspections should include the burner, heat exchanger, main injector and spark probe.

✓ Flue check. This involves making sure that there’s no form of obstructions in the flue terminals as also to ensure that the flue is well installed.

✓ Gas pressure check. This involves making sure that the boiler working with the appropriate pressure.

✓ Boiler fired up. This involves checking for any operating issues.

Generally, a boiler service should be completed within 30 minutes, however this time may vary largely depending on the brand and model.

how much is a boiler service?

How Much Is A Boiler Service?

A broken boiler can be a huge pain and even more so if it occurs during the winter months. A cold house and cold shower is not a situation to be handled with levity especially when there are older people or more vulnerable members in the house. To ensure your boiler keeps functioning the way it should for a lengthy period of time, it’s crucial to ensure that you have your boiler serviced on a yearly basis. But while the summer or warmer months happen to be the most cost effective time to have the boiler servicing done, doing it during the depths of winter can go a long way to ensure that you and your loved ones get through the cold without any unwanted occurrence or boiler issues.

Generally, to have your boiler serviced will cost anything within the range of £80 to about £120, but at times, this can even be more depending on a plethora of factors. The servicing cost will be based on the particular company you choose, the type of boiler you possess, as well as your location in the UK. For instance, if you happen to live in London where demands are higher than the other regions, then you’ll most likely have to pay more money to have your boiler serviced than other homeowners facing similar issues but staying in the other lower demand regions.

Asides from hiring a professional to service your boiler on an annual basis, you should also try to help maintain its efficiency and health in between those services. This will not be a substitute to the regular servicing or even make the servicing a lot simpler, but will surely help keep it at a maximum efficiency while also keeping the cost of your heating bills down.

Before you start thinking about the cost of repairing your boiler, the first thing you’ll need to confirm is whether or not your boiler is still covered by the manufacturer’s warranty. You’d be amazed some warranties can last for as long as 12 years, if yours is still on then you can save yourself a huge amount of of money on your boiler repair. As a result, it’s always crucial to keep the details of your warranty somewhere safe, so you can read them from time to time. You never can tell when the rainy day will come!

Most boiler warranties will require your to get your boiler serviced on an annual basis by a licensed and qualified technician. The cost of an annual boiler service is affected by the time of the year you wish to get it done. When boilers are less useful during the summer months, an annual service is usually relatively cheap when compared to the cold months. Around this period, a boiler service will normally cost within the range of £100 to £150, however for a more accurate quote it’s advisable to contact a couple of professionals and compare their quotes.

The cost of getting a boiler repaired will be affected by a couple of factors including your boiler’s make, the age of the boiler as well as your location and how urgent you need it done. If you have a dead boiler, the cost will typically range from £96 to £348 and a boiler displaying a fault code will cost within the range of £90 to £275. Generally, repairing a boiler will cost within the range of £90 to £400 based on the several factors stated above.

how to fix a broken boiler?

How To Fix A Broken Boiler

To fix any problem when it comes to home appliances, the first step is always to identify the problem while also carrying out thorough checks - a broken boiler is not an exception. Putting enough time and effort in diagnosing a problem can go a lot way to save you both time and money. So here are some of the steps you can take to fix your broken boiler before you put a call out to a licensed engineer.

✓ Check to confirm if your pilot light is on. Whenever you’re facing some issues with your boiler, this should always be the first thing you do. The pilot light being on speak volumes, if the light is off then there’s absolutely no way the flame can start the appliance’s gas supply. You should try to put it back on, if off. To do this, you simply have to follow the detailed instructions on your boiler’s manual strictly. If after following these actions to the letter and the issue remains the same, then you’d probably need the services of an a qualified engineer. Never try to fix the issue on your own.

✓ Check the pressure. The solution to the headaches might sometimes be as simple as examining your appliance’s pressure gauge. Here, the good numbers are around 1.0 or1.5, if it happens to fall below this, then you should open the boiler’s instruction manual. You can also inspect your radiator valves for any leaks. You’d have to call in a specialist to solve the issue.

✓ Check the thermostat. Here, it’s important to note that a faulty thermostat doesn’t necessarily imply a broken boiler. It may just signify that you need to replace your thermostat. Simply check to ensure that your thermostat is turned on and temperature is at the appropriate degree.
