Another precision installation completed by Ralf and the team. This week, work took place in the Tower Hill area, near the City of London, upgrading an outdated system to a high-efficiency Vaillant ecoTEC boiler.
Protecting the system for the long term
To ensure the long-term health of the heating system, a Vaillant magnetic system filter was integrated to catch debris and protect the new heat exchanger. Smart heating controls were also installed for maximum energy efficiency and user ease.
