Heating Engineer FAQs

how to install a gas cooktop in an island?

How To Install A Gas Cooktop In An Island

Are you thinking about installing a gas cooktop in your kitchen island? If yes, then you must know that there are clearance requirements that must be met (before you proceed) between the cut out and the countertop’s edge. Basically, there are incremental requirements for island installation due to the fact that it does not make an assumption that the product is going to be fitted against a rear wall that acts to protect the back of the unit. As a result, while doing an island install we must put the safety of the product into consideration much more that we do a standard install. What’s more? This island clearance requirement develops from a third-party agency and is a standard with all brands. So how do you install a gas cooktop in an island having the aforementioned requirements in mind?

• Use a foil tape to line the inside edges of the cut out. The function of this is to prevent heat damage as well as countertop’s discolouration. Put the cooktop top on a secured surface.

• Identify the pipe coming out of the cooktop’s side or bottom and brush onto the threads of the manifold entrance.

• Pass the pressure regulator onto the entrance of the manifold and make use of a wrench to tighten it.

• Brush the pipe joint compound onto one of the flare union adaptor’s threads and pass it into the regulator’s open end. Make it slightly tight with a full turn of the wrench.

• Connect the flare union adaptor’s open end with the flexible appliance connector hose, upon brushing on pipe joint compound.

• Put foam tape on the cooktop underside’s edges, if your cooktop comes with a glass burner plate.

• Turn the cooktop to set it into the cutout.

• Apply pipe-joint compound onto the flare union adaptor left and secure it firmly into the gas shutout valve.

• Connect the flexible hose connector’s free end with the flare union adaptor.

Can you get oil fired combi boilers?

Can You Get Oiled Fired Combi Boilers?

Absolutely! Oil fired combi boilers are not only a super cool alternative to gas heating, but also offer a cost-efficient means of heating your home. And this is best enjoyed especially if you’re one of the estimated 4 million houses that are not connected to the gas network.

Oil fired combi boiler enables you store fuel close to your property and fill it as required. There many A rated model options available in the market with the modern oil fired combi boilers confirmed to be up to 95% efficient. As a result of their multiple advantages over alternative heating systems, the oil fired combi boiler is expected to increase significantly in the UK. Here are some of the advantages of adding the system to your property.

• Oil fired combi boiler heats up water on demand while also saving a lot of fuel and being super energy efficient.

• Since oil needs more fuel than gas, a great return would be derived from every unit of energy.

• When compared with the other types of boilers, oil fired combi boilers have a considerably lower operating cost.

• A new oil fired boiler typically has a 92% to 95 % efficiency, which is significantly better than the 60% to 70% in older systems.

If you have an idea of how to operate the gas-powered alternative, then operating an oil fired combi boiler shouldn’t be an issue. In a similar way to the alternative, the boiler simply delivers the central heating through the radiators and hot water via your household’s taps.

However, the major difference between the two is the fact that the oil fired boiler needs a regular supply of oil, which is stored in a tank. The hot water supplied by the system is instant as it is connected to the water mains supply.

How long does a boiler last?

If you get the right size boiler for your home and you get it serviced regularly, your boiler could last up to 15 years. It may even last longer than this, but you’ll find that your boiler begins to become less efficient as it gets older. Also, as technology improves, a boiler older than 15 years may not be the most efficient one on the market.

Do biomass boilers need lots of maintenance?

Biomass boilers do require some maintenance. Many manufacturers recommend servicing twice a year, although this is often included in the installation cost. Many systems have automatic fuel loading that removes the need to manually load fuel. You will need to remove the ash from the boiler, but this is as easy as emptying a vacuum cleaner.

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 long does it take to service an oil boiler?

How Long Does It Take To Service An Oil Boiler?

Are you about to service your oil boiler and wondering just how long it would take to completion? Well, you should first know that during an oil boiler service, there are a wide range of things that needs to be checked. As a result, the service can actually take some time and even more, depending on the present condition of your oil boiler.

During a boiler service, your qualified heating engineer will carry out the following tasks:

• Detach and clean both the burner and fan.

• Examine the combustion chamber rope seal.

• Wipe clean and descale baffles.

• Wipe clean and descale the main heat exchanger

• Detach, clean and replace turbulators

• Examine the combustion levels after cleaning.

He’ll also perform some tank and system checks which includes:

• Inspecting and cleaning condensate

• Testing the fire valve

• Cleaning or replacing the filter

• Cleaning the condense trap

• Conducting a thorough inspection of the tank and oil supply pipe to identify possible damages, deterioration as well as debris.

• Pressure testing the oil supply pipe at the point where it goes underground.

• Examining the system pressure.

With all the aforementioned activities and more, an oil boiler service may take relatively longer period of time when compared to it’s counterpart - gas boiler. This is mainly due to the fact that the boiler itself requires a thorough inspection as well as the oil tank where the fuel is being stored. You get your gas through the mains supply, however oil must firstly be stored inside the tank then filled up when it’s almost low. The oil tank will be inspected to identify possible leaks, bulging, corrosion as well as water.

So generally, an oil boiler service should take between the range of 1 to 2 hours to be completed.

do i need a new boiler?

Ad hoc visits from your engineer to fix small issues with your heating system may actually seem cheaper and a lot more affordable, however when a boiler is ripe enough for a change these small issues are always never ending. Over some period of time, these small issues will inevitably get worse and the idea of “mend and make do will be an absolutely false economy. The best course of action in this sort of event is to find a replacement boiler to install as soon as possible. In this article, we’re going to give you some hints that’ll show you when your boiler needs to be replaced. Now let’s take a look!

✓ Insufficient hot water. Here, you’ll have to check the size of your hot water cylinder. It’s crucial to make sure that your boiler is rightly sized to power your heating as well as hot water circuit in line with your demands. You should always seek the advice of a heating expert who can recommend whether to fix or replace the boiler.

✓ Strange noises. It’s normal for components of the boiler to become worn or damaged over time. Replacing the particular component that’s causing the knocking or rattling may seem cost effective at first but more often than not, the noises usually signal a bigger issue which is likely to build up over time. Hence, it’ll be a lot more logical to replace the boiler itself.

✓ Regular repair of your boiler. It’s essential to have your heating system serviced by a Gas Safe engineer on an annual basis. However, when you have to call them more often than once a year for your yearly maintenance, it may be a wise decision to consider getting a replacement.

✓ Other events whereby you may need a new boiler includes when you can’t get the right temperature in your room, when the radiators don’t heat up as they should, when your boiler leaks and if your boiler still has a pilot light.

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.
