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. 

 

How Do You Drain A Central Heating System?

If your radiator has a leak problem or has accumulated sludge in the system, the solution to fix this is by draining the steam from your radiators. Here is your quick guide on how to drain your radiators in just a few simple steps:

Step 1: Switch off your boiler

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.

Step 6: Open the drain valve by turning it counter-clockwise. The water will begin to flow freely.

 

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. The average starting price cost for a central heating installation is around £2,500. Cost factors including your choice of boiler, the style and size of radiators you choose and ease of installation could increase total price to £3,500-£4,500.

 

Can You Bleed A Radiator When The Heating Is On?

No, your central heating must be switched off and cooled down before you start the process of bleeding a radiator. This is important because the radiator may be too hot to touch and there is a risk of boiling water could spray out. 

 

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?

An ideal thermostat setting for your combi boiler is between 18 and 21 degrees. To optimise your boiler’s performance, it is recommended that your radiator dial is set to 75 degrees and your hot water to 60 degrees. 

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. 

 

How Much Does Underfloor Heating Cost?

Generally, underfloor heating costs start from £30 for small projects, and can increase up to £10,000 for bigger projects. The cost of underfloor heating is determined a few factors, such as the type of underfloor heating system you choose, the size of your room and the age of your building. 

If you are thinking about going for an electric system, you could be expected to pay around £180 for 10 square metres. Additional costs of insulation board, screed and heating controls will also need to be considered.
