A property in Lambeth, SE11 needed more than a straightforward boiler swap β the homeowner wanted long-term protection for the new system and proper smart heating control from day one. Ralf carried out a full boiler installation combining a Vaillant ecoFIT pure with an Adey MagnaClean Professional filter and a Hive smart thermostat receiver.
A new boiler is only as good as the system it's connected to. Without a magnetic filter, sludge and magnetite from the existing pipework circulate straight into the new unit's heat exchanger, shortening its working life from the very first winter. The MagnaClean Professional was fitted inline on the return pipework to capture that debris before it reaches the boiler β a small addition at installation time that materially extends how long the new system runs efficiently.
Alongside the mechanical work, a Hive smart thermostat receiver was installed and paired to the boiler, giving the homeowner control over heating schedules and temperature from their phone rather than a single wall-mounted dial. For a property in Central-adjacent SE11 where residents are often out at work all day, this alone can make a meaningful difference to gas usage β heating comes on when it's actually needed rather than running to a fixed schedule regardless of whether anyone's home.
Every radiator in the property was tested for heat output once the system was live, and the full installation was signed off with a Gas Safe certificate before Ralf left.

Yes β they do different jobs. A power flush clears out existing sludge from the pipework and radiators, while a MagnaClean filter fitted afterwards captures any new debris on an ongoing basis so it never reaches the boiler's heat exchanger. Fitting one without the other leaves a gap in protection.
For most households, yes. Being able to control heating schedules and temperature from a phone means heating comes on when it's actually needed rather than running to a fixed timer regardless of whether anyone is home, which typically reduces gas usage over a heating season.
