Installation of a 35kw Viessmann vitodens 100 compact boiler, in Hendon: We removed and disposed of a 20 year old Potterton Kingfisher boiler and Selkirk flue system, as the boilers heat exchanger had split beyond repair due to age. The old boilers Gas supply was also insufficient to provide the correct working gas pressure to the new boiler, so this was upgraded to the correct standard.

We also overhauled the old system on the customer’s request by replacing the 2 port valves with new Honeywell models, and the old British gas pump with a new modulating Grunfoss model. The pipework was then reconfigured to prevent the ingress of air which had previously occurred.

The system was Power Flushed with Kamco Hyperflush and all radiators run through individually to maximise the clean achieved. Our Power flush also passed by a large Magna clean to remove the debris whilst flushing, we then added a Spirotec filter to make sure any possibility of small existing debris does not reach the new boiler, and the system was dosed with Kamco System Safe inhibitor.

We also installed 3 new designer vertical radiators supplied to the customer by the radiator company. One of which was used next to an existing radiator to match the spacing’s of the Columns to appear as one radiator.

The customer was shown round all our work to make sure they were happy, and all controls were explained to them. The bill was then settled, the boiler logged with Viessmann for its five year warranty and registered with Gas Safe.
