But we can tell you making use of electric heating will cost you within the range of an additional £300 to £400 per year more than the conventional gas powered systems. Meanwhile the average UK home making use of heating has been found to incur around £550 on an annual basis while those using electric storage heaters will spend almost £900 every year, according to OVO Energy.

However, there are numerous benefits of using electric heating and some of which can contribute to give a lower cost. If you’re considering the installation of an electric heating, here are some of the benefits you’ll derive.

• Safety. The several risks that comes with traditional systems are greatly reduced with an electric heating system. For instance, there’s no risk of carbon monoxide emissions or potential explosions since there’s no use of fuel to run the system.

This is due to the fact that minimal hardware are needed in the installation - no pipes, no flues, no vents and no ducts to be used. As a result, electric heating systems can also be installed within a shorter period of time.

• Environment. Generally, electricity has a positive impact on the environment especially due to the fact that there are no gasses or heavy metals incorporated in the system’s make up.

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.

what is a gas safety certificate?

What Is A Gas Safety Certificate?

Do you wish to know what a Gas Safety Certificate is and if you need to get one?

If you’re in the UK and you own a rental property, you have a statutory obligation to obtain a Gas Safety Certificate. The law ( Gas Safety - Installation and Use, Regulations 1998) stipulates that landlords as a matter of necessity should have all their gas appliances, fittings,and property flues subjected to yearly checks in order to ensure that they’re are totally safe.

The Gas Safety Certificate can be referred to in a number of ways which includes Landlord Gas Safety Record ( LGSR) or CORGI PROFORMA 12 (CP12). The later dating back to when the official body for gas safety in the UK was CORGI. However, the official body is now known as Gas Safe, hence it’s now usually called a Gas Safety Certificate or something along that line. But regardless of whatever you choose to call it, as long as you reside in the UK, it’s crucial to know that if you need one as soon as possible. So how do know if you need a Gas Safety Certificate?

If you’re a homeowner with a property that you live in, you’re not required by the law to obtain a Gas Safety Certificate. There’s nothing like a homeowner’s gas safety certificate, however we’d recommend you subject all you gas appliances and pipework to yearly examinations to ensure they’re functioning properly and safely.

If you’re a landlord in the UK, you’re required by the law to get a Gas Safety Certificate to ensure your property is safe for your tenants. You must reach out to an approved Gas Safe engineer who’ll carry out annual checks on your appliances to ensure that they’re totally safe.

how much is a new gas boiler?

If you’re thinking about getting a new gas boiler for your home or property, then you might also be wondering how much it’ll cost you so you can set a budget and start planning. As simple as this question sounds, it’s actually very tricky to provide a simple and short answer as the costs of installing a new gas boiler alone varies greatly based on the parts needed, the amount of work required, your location, their availability as well as the company you hire for the project.

When it comes to purchasing a new gas boiler the price you’re expected to pay also depends on multiple influencing factors such as the type, brand as well as your most preferred gas boiler model. However, one thing you should have in mind is the fact that your gas boiler is right at the heart of your home or property and can be a complicated piece of machinery. As a result, you wouldn’t expect gas boilers to come cheap. Generally, it’s going to cost within the range of £500 to about £2,500 to get a new gas boiler. Therefore, it’s always advisable to obtain all necessary details and facts before you decide to purchase a replacement gas boiler.

This price range may seem too high as it’s usually a turn off for most homeowners. However, it’s worth noting that gas boiler replacement costs and gas boiler installation costs are, more often than not, compensated by the saving you’ll make off your utility bills - all thanks to the new and more energy efficient boiler you just installed in your home. And even more importantly, when it has been estimated that roughly half of the amount spent on energy on an annual basis depends on your boiler.

What size boiler do I need?

The size of boiler you need will depend on the size of your commercial property, how many radiators and bathrooms you have and how appliances willl need hot water at the same time. The boiler size refers to its output, which is measured in kilowatts (kW), rather than the actual dimensions. Speak to your boiler engineer about which boiler is suitable for you, as if you have more than one bathroom or a lot of people in your home a combi boiler might not suit you.

how do you bleed an oil boiler?

How Do You Bleed An Oil Boiler?

Bleeding air between the oil supply and an oil fired boiler’s burner is a process that’s often required when the system has run out of oil and the burner has stopped working. Upon refilling the oil tank, the air that has been trapped within the oil pipe when empty has to be freed to ensure that the oil reaches the burner and allows it to start again. So how do you go about the process?

First and foremost, it must be noted that it’s always better to be on the look out for the amount of oil in your fuel tank and get it refilled before it runs out. However, if it does run out, you can take the following steps:

• Identify the burner

The burner is a red plastic cover and it’s usually positioned on the bottom part of the boiler (mostly inside the boiler casing). Once identified, inspect it to see if the lockout button is lit red. If yes, simply unscrew and detach the burner’s red case using a flat head screwdriver.

• Identify the oil pump

You’ll find the oil pump on the burner’s left side which is connected to the flexible oil line. Once done, simply locate the 3 inches long hexagonal stem protruding from the pump and with a small threaded plug screwed into the end. Unscrew the plug in just half a turn ( 180 degrees) with a 4mm Allen Key. At this stage oil will be released, do ensure there’s a cloth or rag underneath the plug to grab the oil freed.

• Press the lockout button

This is the next and final step. However it’s also crucial to note that the burner fan will run for about 12 seconds and discharge some oil from the loosened plug which you can grab with a cloth or rag. Immediately you hear a buzzing sound, use the Allen key to tighten the plug. If enough air has been bled, the system will fire. But if not, then you’ll have to repeat the process again.

how often to service boiler?

How Often To Service Boiler?

A boiler is a vital part of any home especially if you’re in the UK. Not only does provide your entire household with hot water and keep them warm but also adds a good value to your property. Boiler repairs and replacement are both super expensive and stressful, so in order to avoid all these worries, it’s better to have your boiler serviced on a regular basis for your own peace of mind. When you call in a reliable heating engineer, it can immensely raise your boiler’s efficiency while also saving you from more expensive issues down the road.

So if you haven’t had your boiler serviced for quite some time, moved into a new house and not aware the last time your boiler was serviced or perhaps you’re just wondering how often a boiler should be serviced, then you’ve come to the right place! The short and simple answer to this question is a boiler should should be serviced once in a year, and most preferably during the summer months. However, there are a wide range of factors that comes into play so it’s always advisable to check with your manufacturer before you proceed.

According to the law, you’re required to have your boiler services on an annual basis. Failure to do so can render your boiler or home warranty void. Therefore, it’s very crucial to take down the last time your boiler was serviced and also set a reminder to book your next appointment when the time closes in.

If you happen to own an electric boiler you may not need an annual servicing. But you may still be required to perform it annually by your insurance provider.

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.
