What you will need
Nothing but yourself
With sealed system boilers it’s important to manually regulate the amount of water circulating your radiators.
If a boiler has too much pressure it can overflow and with too low pressure the heating in your house can decrease.
You will need to identify the filling loop and the pressure gauge before you do a top up. Both of these will be near your boiler.
The filling loop will have a silver flexible tube with two handles on each side of it and the pressure gauge is a small clock with a red hand or a digital timer.
Make sure you switch the boiler controls off before attempting to top up the pressure. This can be done by pressing the power button on your boiler.
When the handles of the filling tube are in the off position they will be across the flow of the pipe. You will need to slowly turn them so that they straighten up in line with the pipe. By now you should hear the water flowing through into the boiler.
Keep an eye on the pressure gauge as it slowly creeps up to the 1.5 bar marker.
Once you have reached the right pressure you must turn the handles back into the original position.
This shouldn’t take any more than two minutes and is a quick and easy fix. At Acis we have a number of different boilers but every procedure to top up a boiler is the same.
