Heating Engineer FAQs

Can I stay at home while my gas boiler is being replaced?

When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!

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.

what is a condensing boiler?

Condensing boilers are the in-thing when it comes to modern heating systems in UK businesses and across the globe for a good reason. This is primarily due to the fact that condensing boilers happens to be highly efficient as it enables the fuel you’re burning to heat up your home go a lot further. Having a new high efficiency condensing boiler rather than an old G-rated non condensing boiler will not only enhance your heating controls, but also save you a lot of money annually. In this article, we’re going to take you through the basics of a condensing boiler. Let’s take a closer look!

If you’re interested in getting a greener and more efficient boiler, you simply can’t afford to look beyond a high efficiency condensing boiler. This is purely due to the fact that these condensing boilers happens to make a better use of the heat they’re able to produce from burning fuels like oil or gas ( in other words, they require less heat from the burner, which makes them a lot more efficient).

So how does a condensing boiler work? Unlike a non-condensing heat-nly boiler, some heat will be wasted in form of hot gases which are released from the flue. Meanwhile a condensing boiler captures some of the heat from these gases and puts them to use for heating up water that’s coming back from your central heating system. As a result, it requires just a minimal heat from the burner which make the boiler more efficient.

You should take note that all new modern boilers are condensing boilers. Therefore if you’re planning to replace an old boiler with a new one, you’ll definitely be buying a new condensing boiler and benefit from all the efficiency and savings that comes with it.

Do oil boilers need lots of maintenance?

Modern oil boilers do not require a lot of maintenance. OFTEC recommends that oil boilers are serviced and inspected every year. This keeps them running as efficiently as possible and will ensure any issues with your boiler are identified before they cause bigger problems. This servicing is also vital because of the increased risk of carbon monoxide leaking from a poorly maintained boiler.

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.

Where can I put an LPG storage tank?

Your LPG storage tank will need to go outside your property, possibly underground if you have limited space. There are planning rules that restrict where you can put your tank, especially if your property is listed or on designated land. Take a look at our planning permission article to find out more.

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.

Can I use a biomass boiler with other forms of heating?

Biomass boilers can be designed to work with other kinds of heating. The most common of these is solar thermal. This is a popular renewable energy pairing. Solar thermal heating will meet your hot water needs during the summer while a biomass boiler can operate as a backup during the winter when solar thermal panels do not perform as well.
