Alex’s Heating System Rectification Work

After spending one winter and the start of another in a house where two main bedrooms would not heat up, Alex called us to investigate.

On inspecting the system we found a couple of issues: A large combination boiler (great for hot water flow production but carries more resistance through it’s heat exchanger and thus adds more resistance across the system), coupled with a long section of primary flow and return pipe work, primarily run in plastic barrier pipe meant that the resistance across the system was too great to provide good flow to the furthest radiators, even at the boilers top pump speed. The answer would naturally be to replace the boiler with a more conservative unit and upgrade the pipe work. However with the boiler being only a few years old and the pipe work travelling a great length we needed a more cost and time effective solution. We decided to install an auxiliary pump with a close-couple tee. This design meant we could circulate water to the radiator system without the resistance from the boiler, eliminating one of the the initial issues identified. The system now works well and the bedrooms warm up with the rest of the property. Have you got a heating system issue that no one has been able to solve? Please get in touch.
