Fixing an 18-Radiator Worcester Regular System That Wouldn't Heat the Back of the House If radiators at the far end of a large property aren't heating up while the boiler runs constantly on full pump speed, the cause is often a flow rate problem rather than a faulty boiler. On a recent job in Loughton, we resolved exactly this by fitting a custom-made low loss header and an additional circulator pump to a Worcester Bosch Greenstar CDi Classic Regular boiler serving 18 radiato

Our team was called out to a property in Chingford to install a new Viessmann boiler. During the pre-installation survey, it became clear that the existing gas supply pipework wasn't going to be adequate for the new appliance's gas rate - a common issue we see across older Chingford homes where the original pipe run was sized for a much smaller, less efficient boiler decades ago. The problem: the existing run included sections of 15mm pipe and 22mm pipe along its length, neit

Our Gas Safe heating engineers successfully upgraded an existing heating system in Woodford Green that was putting pressure on the boiler and its pump. This system comprised 3 circuits: 2 underfloor heating circuits and 1 unvented hot water cylinder circuit, each with a pump.

Your boiler is one of the hardest-working appliances in your home, providing heating and hot water throughout the year. One of the most common questions homeowners ask is: "How long should my boiler last?" In most UK homes, a modern gas boiler will last between 10 and 15 years when installed correctly and serviced regularly. Some boilers can operate efficiently for longer, while others may need replacing sooner due to poor maintenance, installation issues, or heavy usage. Ave

When an underfloor heating system starts developing cold spots, inconsistent room temperatures, or zones that refuse to heat up, the underlying cause is often more complex than a simple thermostat fault.

If you live in an older property with suspended timber floors, there’s a high chance that a lot of your heat is simply slipping away beneath your feet. At LHS Plumbing Services, we now offer specialist underfloor insulation
