Re-pressurising Your Combi Boiler

We all know that a boiler needs a constant pressure level in order to provide efficient heating for home or business. If there is leak of any type you may not get the benefits of your heating system because of loss or increase in pressure. Gauges on the boiler are usually set at 1-bar and if you notice it has dropped / increased try resetting the pressure, if there is still problem that’s where you need to call your heating engineer.

The process includes:
There are clear instructions for a particular boiler in its handbook, but this gives standard procedures for trouble shooting on boilers. We advise homeowners don’t try DIY as it requires the proper knowledge and experience. It is always safest to call your heating engineer if in doubt.

Low pressure
Switch off the entire system and once it cools down, ensure that both ends of the filling loop are attached to the valves. Secondly, open the valves with screwdriver and allow the cold mains water to enter the system. There will be the sound of water filling and once the pressure gauge hits 1-bar, turn off each valve.

High pressure
A higher reading means you need to check the valves on the filling loop that they are not loose. Once you’re done with this you need to bleed the radiators to reduce the boiler pressure.

Still a problem?
If there is still a problem with your heating system, there may be the problem with your valves. In which case your heating engineer may advise that you need a replacement.

A new boiler is the clean, green, and cost effective option.

It’s a pretty shocking statistic, but if your boiler is over 15 years old, it may be only be performing at 60% efficiency. That’s a lot of money going up in smoke. And the longer you leave it before replacing, the worse it is likely to get, with increasing wastage each year.
There are a range of incentives to get UK householders using less fuel, and in addition to offers of free loft or cavity wall insulation, there are free boiler replacement schemes out there too, such as the Green Deal – available to people who meet certain criteria.

Integrated technology

As more people like to track the energy use in their home, so boiler manufacturers have kept up with the trend, using advances in digital technology to offer vastly increased control of their heating and hot water use. This is another way modern appliances achieve such high efficiency, when used correctly.

Even new boilers need maintenance once installed, but knowing that this will keep your appliance in peak performance for longer and help make your investment pay, should make the annual outlay seem worthwhile.

Remember…

Put in the time researching your boiler replacement plans, and your investment should pay off with significant efficiency savings. Getting a quote and the opinion of a plumber or central heating professional is sure to make a clear financial case for ditching that old boiler ASAP.
