Where to check boiler pressure and why it changes. In central heating in the UK and Europe, boiler pressure and central heating system pressure is usually measured in bar. For years, central heating systems were “open vented,” with a feed and expansion tank (known as an F&E tank or a header tank), usually in the loft.
The CB-Hawk boiler management control system ('''Figure 1''') combines the functions of a flame safeguard programmer with those of operating and firing rate controls. It also monitors the fuel pressure and temperature (if required) with solid-state sensors and provides a built-in safety limit control of those functions.
A simple way to check your operating stat is isolate the supply and let the tank run cold overnight say. Then next day turn the stat down to the lowest setting.Then turn it up until you hear it click and turn on the electric supply. You can then check for voltage on both sides of the stat until it clicks off/voltage would be off on the load side.

Most boiler manufacturers will let you know the maximum flow of water in litres per minute, so you will be able to work out if the boiler is suited to your mains flow. However, if you request the help of an expert they can check the temperature and the flow rate to ensure you get the perfect boiler.
Boilers must have a proper pressure-relief valve, located at the top, which opens when the pressure reaches 30 pounds to prevent the boiler from exploding. If you ever see water draining out of the relief valve, chances are that the system is operating under excessively high pressure and should be checked by a professional.
Generally, the ideal pressure is between 1 and 2 bars, but this may vary from boiler to boiler. Ask your heating engineer. Check the pressure gauge. A quick look at the pressure gauge is enough to check your boiler’s pressure. Depending on what model your boiler is, this comes in different forms:
The bottom blow down is done at least daily (more often depending on boiler water conditions) to blow out scale and mud from the bottom of the boiler. If possible you should lower the firing rate of your boiler when you do the bottom blow down then return to normal firing rate after the blow down. Question 11.
Boiler efficiency may be indicated by. Combustion Efficiency - indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust; Thermal Efficiency - indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boiler, exclusive radiation and convection losses
