how to fix a broken boiler?

How To Fix A Broken Boiler

To fix any problem when it comes to home appliances, the first step is always to identify the problem while also carrying out thorough checks - a broken boiler is not an exception. Putting enough time and effort in diagnosing a problem can go a lot way to save you both time and money. So here are some of the steps you can take to fix your broken boiler before you put a call out to a licensed engineer.

✓ Check to confirm if your pilot light is on. Whenever you’re facing some issues with your boiler, this should always be the first thing you do. The pilot light being on speak volumes, if the light is off then there’s absolutely no way the flame can start the appliance’s gas supply. You should try to put it back on, if off. To do this, you simply have to follow the detailed instructions on your boiler’s manual strictly. If after following these actions to the letter and the issue remains the same, then you’d probably need the services of an a qualified engineer. Never try to fix the issue on your own.

✓ Check the pressure. The solution to the headaches might sometimes be as simple as examining your appliance’s pressure gauge. Here, the good numbers are around 1.0 or1.5, if it happens to fall below this, then you should open the boiler’s instruction manual. You can also inspect your radiator valves for any leaks. You’d have to call in a specialist to solve the issue.

✓ Check the thermostat. Here, it’s important to note that a faulty thermostat doesn’t necessarily imply a broken boiler. It may just signify that you need to replace your thermostat. Simply check to ensure that your thermostat is turned on and temperature is at the appropriate degree.

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.

How do I re-pressurise a boiler?

  1. Switch off your boiler and let it cool completely
  2. Make sure both ends of your filling loop are attached
  3. Open both valves to allow cold water into the system – you’ll hear it start to move
  4. Look out for your pressure gauge to show 1.5 bar
  5. Close both valves
  6. Switch your boiler back on
  7. Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!
how does a gas boiler work?

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

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.
