Gas Safe registered plumbing and heating contractors serving Chandlers Ford and Hiltingbury. Boiler installations, system design, underfloor heating and more.
Chandlers Ford is a suburb of extended houses, and most of the heating problems we are called to here trace back to a property that has grown while its heating system has not.
The bulk of the housing went up between the 1930s and the 1970s, with Hiltingbury and Valley Park added later. Plots are generous by Hampshire standards, which is exactly why rear extensions, garage conversions and loft conversions are so common. Each one adds heat demand to a system that was sized for the original footprint.
The assumption we most often have to correct is that this means a bigger boiler. Frequently it does not. A proper heat loss calculation tends to show the existing boiler has the output but the radiators are undersized and the system has never been rebalanced after the last change. Fitting a larger boiler onto an unbalanced system makes efficiency worse, and it cycles more.
Where an extension is being planned from scratch, underfloor heating is worth considering seriously. The floor build-up can be designed in from the start, and because it runs at a lower flow temperature it works well alongside the existing radiator circuit if the system is zoned properly. Retrofitting into an existing floor is possible but a bigger job.
Like the rest of this part of Hampshire the water is hard, so scale reduction is worth fitting alongside any new combi. We cover Chandlers Ford, Hiltingbury, Valley Park, North Baddesley, Hursley, Ampfield and Otterbourne.

Often not, and this is the question we get asked most in Chandlers Ford. A heat loss calculation regularly shows the existing boiler has spare output while the radiators are undersized or the system was never balanced after previous work. Oversizing the boiler usually costs you efficiency rather than gaining you comfort.
Yes, and an extension is the ideal place for it because the floor construction can be planned around the system rather than squeezed into it. It runs at a lower flow temperature than radiators, so the design needs to account for the whole system, not just the new room.
