The Brief

A family home in Caerphilly had an ageing boiler that had become unreliable and inefficient. The homeowners wanted a modern, high-efficiency combi boiler that would deliver dependable heating and hot water while bringing their running costs down. They came to Book Your Boiler for a clean, properly commissioned installation carried out by Gas Safe registered engineers.

What We Did

Our work included:

  • Surveyed the system: We assessed the existing heating system, talked through how the family used their heating and hot water, and recommended the right high-efficiency combi boiler for the home.
  • Removed the old boiler: Safely disconnected and removed the old unit, making sure all gas and water connections were properly isolated before any work began.
  • Installed the new combi boiler: Fitted a modern high-efficiency combi boiler, keeping heating and hot water in a single compact unit, with all connections made to manufacturer specifications and current standards.
  • Flushed the system: Carried out a full system flush to clear out sludge and debris, helping the new boiler run cleanly and protecting it for the long term.
  • Commissioned and tested: The boiler was filled, pressurised and thoroughly tested. All controls, thermostats and safety devices were checked to confirm everything worked correctly.
  • Registered the warranty: We registered the manufacturer warranty on the homeowners' behalf and showed them how to operate their new boiler with confidence.

The Result

A reliable, efficient heating system that delivers consistent warmth and hot water across the home. The new high-efficiency combi boiler has lowered the household's running costs, and the family have the peace of mind that comes with a fully commissioned installation, a flushed system and a registered manufacturer warranty.
