How Long Do Your Boiler Installations Take?

A question many of our customers want to know is “How long do your boiler installations take?”. In most cases, a new boiler can be installed in a single day.

However it may take longer for the system to be fully up and running. This means the property may be without heating and hot water facilities until the project is complete. 

Typically if the new boiler to be installed is the same model and is put in the existing place as your old boiler, this is a much quicker service. 


What Should Boiler Pressure Be When Heating Is On?

It is important that your boiler pressure is stable in order for your central heating system to work more efficiently. Normally, your boiler pressure gauge should read between 1 and 2 bar. 

If it is above 2 bar, this means you’ll need to release some of that pressure. You can do this by bleeding one of your radiators in your home.

Step 2: Turn off the gas to the boiler

Step 3: Close off the water intake valve

Step 2: Locate radiator with drain-off valve

Step 3: After all of your radiator valves are open – attach a long piece of hose pipe to the drain-off valve with a jubilee clip. Place the end of hose in the sink.

How Much To Install Central Heating?

Your location, the size of the property and the type of boiler you choose will determine the cost of your new central heating installation.

How Do You Add A Cleaner To A Central Heating System?

Before you add a chemical cleaner to your central heating system, you’ll need to drain and replace the water in the system. 

Make sure you check the manufacturer’s instructions for the required quantity of cleaner you’ll need to use. Some may include a neutralizing product which is mixed with the chemical.

If you have a vented system, the chemical cleaner will need to be added to the water in the feed and expansion tank. 

For sealed systems, you’ll have a special attachment hose that is connected to the air vent on one of the radiators. You will need to use a sealant gun to inject the cleaner into the system.

Once this is done, you can run the central heating back to normal again. It can take up to a week for the cleaner to fully circulate around the system. After it has properly distributed, you will need to drain and fill the system until the water drained off is clear. 


What Temperature Should My Combi Boiler Be Set At For Central Heating?

The timer for your central heating should be set most convenient to you. Generally, setting your central heating to come on half an hour before your alarm clock and half an hour before coming home from is a good place to start.
