G3 Qualified on unvented cylinders 30+ yrs Working DA postcodes 180521 Gas Safe registration - Gas Safe registered #180521 - 4.9★ average from 159 Google reviews - Office open 8am–9pm, 7 days a week Bexley property patterns ## The problems we see again and again in Bexley. Local heating and plumbing issues are rarely random. They follow the era of the property, the pipework, the water conditions and the way the house has been extended. Here is what our diary in DA5, DA6, DA7 actually looks like. ### Undersized system boilers It is common to find Bexley family houses with a boiler that was picked to be cheap rather than adequate for the property. We do the heat-loss calculation and quote the right output, honestly. ### Unvented cylinder compliance Unvented (pressurised) cylinders are legally notifiable and must be worked on by a G3 qualified engineer. Danny holds that qualification, so installs, replacements and annual services are done correctly with the paperwork. ### Cold master bedroom above the boiler A classic 1930s semi symptom. Usually a balancing and radiator-sizing issue rather than a boiler fault. We test, balance and only recommend replacement when it is genuinely needed. ### Second bathrooms and en-suites Adding a second bathroom to a Bexley family home is one of the most common projects we take on. Danny will design the pressure, capacity and pipe layout so both showers can actually run at once. ### Sludged systems in long-standing homes 20+ years of magnetite build-up in older radiators is standard in DA5. Power flushing plus a magnetic filter usually restores full output without touching the boiler.
