It is critical that in modern low water content type condensing boilers, that BLADES use within our system, are maintained at the correct pressure. As these are sealed systems if the pressure drops below the specified level for any reason, then the boiler will not operate.
On smaller boilers below 45kW this can be undertaken manually using a filling loop, which allows a connection to be made between the water main and the boiler, this is normally only used on domestic type installations.
For boilers over 45kW it is compulsory to install a automatic system to maintain system pressure, but we would also recommend it for all types of commercial installations.
If required, we can supply a compact fully automatic pressurisation unit as an optional accessory. This unit can be easily fitted directly to the outside of our frame. We make allowance within our prefabricated installation for easy connections to be made to pipework and electrical systems. This unit will automatically keep the system at the correct pressure for the boiler.
The pressurisation unit should never be used to initially fill the boiler and a separate connection is provided within the BLADE frame for this purpose.
