Find a Heating Engineer you can trust near you.

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.

To ensure that your boiler is safe and operating efficiently, it’s essential to have it serviced on a regular basis.

Generally, a boiler service will deliver a wide array of benefits which includes the opportunity to identify safety issues like a possible leak of carbon monoxide, efficient use of energy and reduction in energy bills, prevention of breakdowns, a valid warranty when the boiler is serviced regularly by a qualified engineer as well as an extended lifespan. So what exactly does a boiler service cover? This guide will give you a good insight as to what happens during that service.

Before we get started, it’s very important to note that the work done is always as good as the engineer you employ. Therefore, it’s advisable to make sure your preferred engineer is qualified before proceeding with the service. Below are some of the basic practices the engineer may perform during their visit.

• Thorough Inspection

During the visit, the engineer will carry out a detailed examination of your boiler to ensure it still meets the current standards while also making sure that there are no leaks or corrosion. What’s more? They’ll also examine the boiler’s flame for any faults.

• Boiler Casing Removal

The boiler casing will be detached to check all components and ensure they’re free from all forms of dirt and see to it that they’re all working just as they should. This will include examination of the heat exchanger, main injector, burner and spark probe.

• Flue Examination

The engineer will inspect the flue terminals to make sure there are no form of obstructions and it’s also safely installed.

• Gas Pressure Examination

This is done to make sure the heating system is operating at the right pressure.

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.

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.

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.

Installing your Nest thermostat may not be as easy as screwing a light bulb, but we can also assure you that it isn’t very difficult either. However, if you lack the needed training or experience to pull it off, we’d recommend you hire the services of a professional in order to save yourself some time and money. This guide will give you some quick and easy steps to follow and ensure you make no errors during the installation process.

Once installed removing the Nest Thermostat can be done. To get started, you’ll need just a Philips head screwdriver which Nest has thoughtfully provided with the device.

• Turn off the Nest Thermostat by switching the circuit breaker to the off position.

• Label or mark your old thermostat’s wires. However, if you notice your thermostat is tagged 120v or 240v, or possesses thick wires, do not connect the wires to the Nest as you have a high voltage system.

• Uninstall the old thermostat by locating detaching the wires coming out from the wall into the thermostat. Once done, simply unscrew the device from the wall

• Mark the spot of your thermostat. Do this by threading wires through the Nest base plate’s centre incorporate the tiny bubble level. Once done, you can then use a pencil to mark te two screw holes.

• Attach the trim plate. If you wish to cover the screw holes, simply install the trim plate in the Nest box’s bottom to the base plate.

• Using the screws and screwdriver, attach the Nest base to the wall.

• Connect the wires to the Nest by putting the labelled wires in the Nest’s corresponding ports.

• Put the Nest display by lining up the connector on the display’s back.

• Turn on the power by switching the circuit breaker to the on position

• Connect your Nest thermostat to the WiFi network.

• Follow the on-screen guide and set the temperature.

• Use your smartphone or tablet to download the Nest thermostat’s mobile app to monitor and control your device remotely.

Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:

• Switch off your boiler and let it cool completely

• Make sure both ends of your filling loop are attached

• Open both valves to allow cold water into the system – you’ll hear it start to move

• Look out for your pressure gauge to show 1.5 bar

• Close both valves

• Switch your boiler back on

• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!

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.
