The pressure on my boiler is too low, how do I increase it?
From time to time the pressure on your boiler can become too low which is not uncommon. Typically, the pressure should be between 1 and 1.5 bars on the pressure gauge. There are two things you can do to fix this.
Top up your boiler
Depending on the make and model of your boiler you may ‘top up’ the pressure using either the filling loop or using an internal filling key – it is always best to check your boiler instruction manual to see which of these your boiler has.
Bleed your radiators
Bleeding your radiators also reduces the pressure in your boiler. You can do this yourself using a radiator key to release the pressure inside or contact your heating engineer to do this for you.
What is a combi boiler?
Combi boilers are the most popular type of boiler in the UK, they provide households with both central heating and hot water unlike conventional boilers. Combi boilers will provide you with hot water after a few seconds when a hot tap or shower is turned on and they don’t require separate water tanks or cylinders making them a great space saver in your home. They’re a good economical option too as they only heat water as and when it is needed and offer greater reliability than conventional boilers
How often do I need to have my boiler serviced?
It is a good idea to have your boiler serviced at least once annually to make sure it is operating safely and efficiently. Some manufacturers require an annual service on your boiler in order to ensure your boiler’s warranty is valid. Contact your boiler’s manufacturer to arrange a visit from a Gas Safe registered engineer who will be able to carry out the service for you and give you peace of mind that your boiler is running optimally, reducing the risk of faults or breakdowns in the future.
Do I need to buy a flue kit separately?
Many of our boilers at Wolseley come with a flue pack included but with some boilers you’ll need to buy a flue separately – Before you purchase, read the boiler specifications carefully to determine whether you need to buy a flue pack too.
