Heating Engineer FAQs

how long does a gas boiler last?

When it comes to gas boilers, this is one of the most frequent questions that always pops up and for a good reason. When you invest a considerable amount of money to acquire and install a gas boiler in your business property, it’s only reasonable not only to expect the boiler to warm up your property efficiently, but also to do so for a long period of time. If you’ve just bought or about to get a new gas boiler, it’s likely you won’t have to worry about getting a replacement for a lengthy period of time. Several commercial gas boilers will last for anywhere between 10 to 15 years on the average. However in the event whereby you have an existing one that’s fast approaching the end of it’s useful life, then you should know the time go get a new gas boiler is just around the corner, and the earlier you make the purchase, the better (to avoid any surprise breakdowns that’ll leave your home super uncomfortable).

Just like any other home appliance, it’s a fact that an older gas boiler ( especially those that have been installed over a decade ago) are significantly less efficient that the new modern ones. When the older versions were manufactured is a completely different time to now as both technology and climate concerns are wide apart. So when your existing boiler is approaching the end of it’s useful life, it’ll be wise to start saving up to cover the cost of getting a new one. However, if it’s only about 5 years ago your boiler was installed, it’s highly likely to still be very efficient.

how does the smart thermostat work?

If you’re building a connected home, a smart thermostat allows you to change the temperature in your home. And not only do several smart thermostats come with touch screens and a user friendly interface, but they’re also compatible with Amazon Alexa, Google Assistant and other voice controlled personal assistants. So how does a smart thermostat work? Let’s have a look!

Generally, smart thermostats are connected to the home’s Heating and/or Air Con system via C wire (common wire). Homes that lacks a C wire (especially older homes) will have to install one first before getting a smart thermostat. The C wire is a crucial element in the installation process as it works mainly to wire your smart thermostats into the Boiler system without tampering with the wiring for the other appliances in the house.

The smart thermostats comes with some special temperature setting which you can access by connecting them to your home’s WiFi. These include:

• Mobile Control

Most smart thermostats are specially designed to enable users to control the temperature of their home from the comfort of their couch or car via their unique mobile apps. This feature is just perfect if you particularly like getting the perfect temperature in your home without having to get out of bed.

• Humidity Controls

Although, the humidity of your home can not really be adjusted with a smart thermostat but you can always stay on top of it by monitoring it or setting an alarm on your phone to go off when the humidity changes.

• Geofencing Feature

With a smart thermostat, you can choose the particular times of the day you want it in action. This feature enables you to go on impromptu travels without having to worry about your energy bills - some smart thermostats come with the geotracking feature which determines when you’ve left the house and adjusts the temperature of the home accordingly with your energy usage in mind.

How does the A-G gas boiler rating system work?

The A-G scale refers to the energy efficiency of your boiler. G-rated boilers are the least efficient, and give you less heat and hot water for your money. Installing an A-rated boiler will reduce your energy bills and carbon emissions. Don't compromise on cheaper, lower rated boilers, you will save yourself more money longer term with an A-rated model.

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 much is a new oil boiler?

How Much Is A New Oil Boiler?

An oil boiler is a very useful tool for providing both central heating and domestic hot water to a property by burning oil. As a result, they’re simply one of the most common alternative heating methods used in homes throughout the UK. If you’re not connected to the mains gas network, then it’s a no brainer to depend on another fuel for central heating purposes - oil. Therefore, if you’re looking to get a new oil boiler, you’d need to identify the size and price as there are a plethora of models to select from - all coming in a large array of sizes and prices. We’ve put together some important details about the prices to give you a good insight on the amount you’d have to incur to procure a new oil boiler. Let’s have a look!

Generally, gas boilers are less expensive when compared to the oil boilers. You can get a wide range of gas boilers from a starting price of £500 to £600, meanwhile you’d rarely find an oil boiler less than £1000 in the market.

The lowest priced oil boilers are typically priced starting from around £1000, and the best in class oil boilers normally costs more than £3000.

The rule is, the most expensive oil boiler is typically the largest one. So to have an idea, the bigger it is, the more money you’d have to spend. Oil boiler’s size is measured in kilowatts (kw), which showcases its power. To determine the type of oil boiler that best suits your home, the most significant factor would be the size as a bigger home will require a bigger oil boiler. You have an option to choose between the combi, conventional and the system models of oil boiler.

Where can I put an LPG storage tank?

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.

This also means that when you settle for an old or ageing boiler, you’ll have to unnecessarily incur high utility bill in order to heat your home and have hot water on demand. In this kind of situation, the most effective and practical solution is to fit a new gas boiler in your home. This will provide you several benefits such as improved efficiency and reliability as well as reduced operating costs.

And as you would have expected, like many other home improvement project there’s always an element of disruption that you’ll have to put into consideration when fitting a new gas boiler system. Good news is, with a qualified and experienced heating companies, these disruptions can be kept at a minimum.

✓ Converting a regular to a combi boiler - Due to the fact that these type of project is usually labour intensive, it’ll take longer to complete - about 2 days.

✓ First time installation of new boiler to a home. This will usually take about 3 or more days because new pipes and other tasks need to the installation will be carried out.

can you replace a gas boiler with an electric boiler?

Can You Replace A Gas Boiler With An Electric Boiler?

In the UK, there are about 22 million households that are heated with the use of a gas boiler. However, do not assume that they’re the best type of boiler to install. The fact is, if your house isn’t connected to the main gas supply, the best option is for you to install an electric boiler rather than a gas boiler. So is it possible to replace a gas boiler with an electric boiler? The simple answer is yes. Both heating system options work in varying ways and also with a different impact on the environment.

The gas boiler is able to generate heat with the help of a gas burner. A heat exchanger is linked to the burner and heats the water available in its chamber. The hot water is then supplied to the heating circuit.

However, the thing is that natural gas can actually be more affordable when compared to using electricity to operate your boiler, but they have a negative impact on the environment. This is because gas boilers make use of an odourless, colourless and poisonous gas - carbon monoxide.

Meanwhile electric boilers are powered by electrical energy, hence, no carbon monoxide leak risks. Instead of using gas to heat up water, electric boilers distribute energy to heating elements which, in turn, heats up the water. So thinking about what’s best for the environment, you’d go for electric boilers. However, they’re more costly and are not as efficient as oil boilers.

If you reside in a smaller house that’s not connected to the main gas supply, then you might want to consider installing an electric boiler. However, if you live in a larger house, an electric boiler may not be the best option as they’re mostly designed to generate little quantity of hot water.
