Find a Heating Engineer you can trust in Welwyn Garden City.

During a boiler service, your boiler engineer will perform a series of checks to ensure that your boiler is safe and efficient. First, they will conduct a visual inspection to check for any corrosion or leaks. They will also check the flame in your boiler. They’ll then remove the boiler casing and check all the components, including the heat exchanger, burner and spark probe, then clean the inside. After this, they’ll check the flue for obstructions and ensure that it’s safely fitted. They will then do a gas pressure check to ensure the boiler is working at the right pressure, before firing it up to check for any working faults.

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.

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 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.

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.

Breakdowns of boilers are quite common during the winter months and are usually very expensive to repair when this occurs. According to the research carried out recently by uSwitch, repairing a boiler can cost an average of about £314 with a figure over 20 percent of homes experiencing various heating system issues last year.

To answer the question of whether or not your existing home insurance will be enough to cover the boiler breakdown, the answer is probably not. This is due to the fact that heating system faults or breakdowns is a very common occurrence and as a result of poor maintenance practices as well as a high repair cost, several insurance companies often remove it from their home insurance policies.

Generally, you’d be given an option of what is termed as “emergency home cover which is an add on or extra to your home insurance policy. Luckily, this add on is quite inexpensive and may be as little as £4 or £5 per month. Depending on your need or budget, you can also purchase the add on as a “stand alone from your current insurer or another company. However, the standalone option is usually more expensive.

The emergency home cover normally provides coverage for the boiler repair cost and few times, the rest of the central heating system as well. Being fully aware how important a boiler can be, insurance companies usually deliver a rapid response service as suggested in the name, “emergency home cover. However, the maximum pay-out for call out charges is capped at a particular amount which usually ranges from £500 and £1,000. Apart from the call out fees, the emergency cover also includes a limit on the pay-out amount for future required repairs of heating systems which includes both parts labour.

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.

A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.

Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.

✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.

✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.

✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.

✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer
