Heating Engineer FAQs

How do I know if my gas boiler needs replacing?

If your boiler is making strange noises or smells, or doesn’t seem to be working properly, it may need replacing. Boilers usually last about 10-15 years. Even if your boiler is working normally, it’s worth replacing when it gets this old. An annual check will establish if there are terminal problems with a boiler that cannot be fixed.

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.

Can I repair my own boiler?

No. You must never repair your own boiler – only a Gas Safe-registered engineer can do any work on your boiler. You can do simple DIY tasks to repressurise your boiler or stop a leak, but if you have to remove the outer casing of the boiler or touch the flue then you must get a qualified boiler engineer to take a look at your central heating system.

does home insurance cover boiler repairs?

Does Home Insurance Cover Boiler Repairs?

When winter comes, your boiler is most likely to be one of the most used appliances in your home. It keeps operating for several hours to ensure your house remains warm and conducive and then during those cold evenings, it supplies the much needed hot water to guarantee a restive night. But with so much usage and many moving parts, you’d naturally expect your boiler to breakdown at some point especially if it’s 7 years old or above. So what’s the next line of action when it happens, leaving your radiators off and water cold? With the likely high boiler repair cost, it’s only logical to consider whether your boiler repairs is covered by your home insurance.

In almost all situations, the standard home insurance will not provide coverage for the cost of repairing or replacing a broken boiler. Being fully aware that boiler breakdowns are mostly caused by a lack or not so regular maintenance practices or servicing, most home insurance providers will exclude it from this from their offerings. In fact, a home insurance is more likely to provide coverage for the damage that has happened as a result of a broken appliance. For instance, the damage caused as a result of gas, oil or water leaking from a boiler are more likely to be paid for by the home insurance providers, but they’ll not pay for the repair or replacement of the broken boiler itself.

If you need our home insurance to cover your boiler repair, then you might just be able to get an extra insurance cover from your provider that includes a broken boiler repair. You can consult them to determine if this is possible as well as the cost to be paid per month. This will normally cost about £5 to £10 per month, but it gives you a peace of mind knowing you’re covered if your boiler happens to breakdown.

What is the best oil boiler on the market?

What Is The Best Oil Boiler On The Market?

With a plethora of sizes and models available in the market today, it can be a hassle choosing the best oil boiler. There are 3 main types of oil boilers which includes an oil combi boiler, a regular oil boiler and a system oil boiler. Within these three types, we have a wide range of models and sizes with varying heating and hot water demands.

With tonnes of oil boiler brands out there, the problem is the over crowding on the market with oil boilers that are not only over priced, but also of mediocre quality. From our research, we’ve been able to identify three major bands that are simply outstanding - Warmflow, Grant and Worcester Bosch. However, out of the lots, Warmflow is simply the most efficient and also comes with several qualities such as :

lUK & Ireland’s only AA rated combi boiler

lMarket leading innovation

lEasy and simple to install

l45plus years heating homes

l5 and 7 year warranty available

The oil boiler comes with an outrageous 5 year warranty on their Titanium which when compared to some similar Worcester Bosch Oil boilers is a whooping 3 years difference. Furthermore, the brand also offers a special “out-of-the-box 5-year warranty which enables the warranty to be valid as long as the installation is done by a qualified oil boiler technician. This may, however, seem normal until you realize other brands like Grant, will only honour their 5-year warranty when the boiler is installed only by their accredited technicians.

Warmflow offers an oil boiler to suit every property that is situated off the grid. These includes the modern and stylish U-Series, outdoor-compatible K-Series as well as the quietly efficient B-series which is designed for indoor installation.

How to repair a boiler leak?

If your boiler is leaking, there are some checks that you can do yourself. However, you should never attempt to repair your boiler yourself – only a Gas Safe-registered engineer should conduct repairs.

There are 3 main reasons why your boiler might be leaking: there’s a pressure valve fault, a temperature valve leak or corrosion in the system. An engineer will be able to spot the problem quickly, but in the meantime there are a few things you can do:

Check the pipe fittings

If your boiler is leaking water around the pipe fittings, it could be an installation fault and you should get in touch with the engineer that fitted it. You can check the pipe fittings by drying the area then waiting to see if the water appears again. If it does, you may be able to do a ¼ turn of the pipe to stop it. However, you should still call the engineer that installed it to ask them to check the PTFE tape on the inside.

Inspect the seals

Over time, the rubber seals on a boiler can start to perish, so if you have an old boiler this could be the source of your leak. If you have a new boiler, it could be caused by your boiler running over pressure.

Heat exchanger corrosion

Unfortunately, if a boiler engineer discovers that the boiler is leaking water from the heat exchanger, this is the end of the road for your system. The heat exchanger is the most expensive part of your boiler, so it makes more financial sense to replace your boiler with a newer, more efficient model rather than try to replace it.

can i repair my own gas boiler?

Can I Repair My Own Gas Boiler?

If you’re more of an handy person, then you’d probably want to fix everything you can around the house while saving yourself some money that would have been spent on hiring a professional instead. This is a very cost effective but at the same time you must know that some tasks are usually more difficult than others, and a good example of those complex tasks is boiler repair. Not only can this be very tough, but they can also potentially be one of the most dangerous home appliances you can acquire. So with that in mind, what can be done to ensure your gas boiler is taken care of and in the event whereby it starts to malfunction, what can be done to remedy the situation?

With regular maintenance and repair of your gas boiler, you’d have absolutely nothing to worry about. However one of the fear several DIYers have is the fact that they might just end up incurring more expenses on services they didn’t really need in the first place. But when it comes to gas boilers, it’s necessary to be certified to work with them as it’s very dangerous to tackle it all by yourself. Despite this, there are still some minor issues that you wouldn’t need to hire a technician to resolve. In some cases, all that would be needed is simply to reset the boiler. To identify where the reset button is, simply go through your boiler’s manual for more information. Most times, all you’ll have to do is press down the reset button for a couple of seconds. If the boiler isn’t fully restored to its normal proper functioning state after two resets, then you may need to call in a professional for help.

how does a gas boiler work?

A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.

Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.

✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.

✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.

✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.

✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer
