Depending on which type of boiler you choose, the price of a new boiler averages between £500 to £1,500. If you are simply replacing your system with the same model boiler, the cost will be slightly cheaper. However, if you are converting to a new type and require a full boiler installation, you can expect to budget a lot higher.
If you are removing a radiator or installing a new radiator, it is important to drain down your heating system. To do this, first, you’ll need to switch off the central heating system and empty out the water. Simply turn off the main stop valve to ensure the water supply doesn’t refill.
Then, apply a hosepipe and jubilee clip to the outlet of the first drain valve. The hosepipe must lead to the bath or outside to let the water drain away properly. Simply unscrew the valve with a spanner and let the water flow out.
Leave it to drain for approximately 15 minutes and test it by opening the bleed valve. If more water comes out, leave it a bit longer. Once the water finishes draining, ensure all the bleed valves are tightened back up.
Then, close the valve on the radiator with the hosepipe and remove the jubilee clip. Be aware that the hosepipe may still contain a little bit of water, so prepare with a plastic tub to stop it from spilling everywhere.
Combi boilers are the most common boiler type in the UK. A combi boiler solution heats water directly from the mains as soon as you turn a shower or hot water tap on. This saves the need for a hot water storage cylinder or a cold water tank.
Combi boilers work instantly with different fuels and are quick to install. This means they are a cheaper and more economical system to run, particularly for domestic convenience. In fact, over 70% of UK homes choose combi boilers.
To fit a standard new boiler will cost you around £1,000. A straightforward job would involve replacing the existing boiler with a new model. This budget doesn’t include the price of the actual boiler itself, only labour cost.
A gas boiler system works continuously heating water. The heated water is pumped around the property through pipes and radiators.
It operates by burning carbon-based fuel with oxygen to produce carbon dioxide. This is burned within the boiler’s combustion chamber and warms the water through a heat exchanger.
First, you need to make sure that your central heating system is switched off properly. Afterwards, place a bowl or tray underneath the bleed valve and have a large towel prepared with it.
Once you have the valve pointing into the bowl correctly, you can use a screwdriver or radiator key to slowly open the bleed valve. Keep this left turned until water comes out instead of air. You should hear the air hissing out of the valve, to begin with.
As soon as the sound stops and water starts coming out, you need to turn the key or screwdriver clockwise to shut the valve. After this is done, you can switch your heating back on.
A new boiler typically takes around 2-3 days to install. Depending on the project scale, a standard boiler installation could be completed in just 8 hours. If the job is more complex, a full day might be required.
While both are fossil fuels, LPG is made up primarily of propane and butane and is stored as a liquid under pressure. Natural gas, on the other hand, is mostly methane and is delivered via pipelines as a gas.
LPG can often be a more cost-effective fuel source compared to electricity or heating oil, especially in areas without access to natural gas. Over time, the efficiency of LPG appliances combined with competitive pricing can lead to notable savings on energy bills.
Transitioning to LPG typically involves installing an LPG storage tank and setting up the necessary pipework. For homes or businesses already using a different type of gas, many appliances can be converted rather than replaced. Our team can assess your specific needs and provide a tailored solution.
