WHAT FAILS HERE
Heating faults common in Deptford
Deptford's landscape of subdivided period homes means we're often diagnosing a mismatch between a modern combi's capability and the reality of several households' morning routines happening concurrently.
01
Combi boiler struggling with simultaneous use
A single combi retrofitted to serve a whole converted house can be undersized when multiple flats draw hot water at once. An engineer assesses the boiler's kW output against the property's demand, checking flow rates at different outlets to see if the unit is being overwhelmed.
02
Poor hot water pressure in upstairs flats
In conversions, the original pipework may be kept but shared, leading to significant pressure drop over long runs, especially to top-floor bathrooms. The check involves measuring dynamic pressure at the problem tap and tracing the pipe route for unnecessary restrictions or an undersized main feed.
