Boiler installation andair conditioningacross Andoverfrom Basingstoke

The 1960s and 70s Andover estates were plumbed in microbore on the same rationale as Basingstoke's — cheap and quick. Fifty years of untreated water later, the 8mm and 10mm runs are partially blocked with magnetite and the downstairs radiators sit lukewarm while the boiler cycles. Powerflushing with the correct pump pressure for microbore, followed by inhibitor and a magnetic filter, is the fix; brute force on small-bore pipe does more harm than good.

Picket Twenty and Augusta Park properties are built to modern airtightness standards with mechanical ventilation, and they hold summer heat exceptionally well. South-facing bedrooms regularly become unusable in July. Air conditioning is the practical answer, but external unit siting on these tight plots needs planning around boundaries, neighbouring windows and the estate's own restrictions — which is a survey conversation, not an afterthought.

Out at Abbotts Ann, Weyhill and the Clatfords, pipework frequently runs through unheated outbuildings, crawl spaces and long external sections. Those are the pipes that freeze and split in a cold snap, and the condensate discharges that lock the boiler out overnight. Proper lagging, sensible re-routing and frost protection on the vulnerable sections prevent a January emergency that costs many times more than the preventative work.

Andover shares the Hampshire chalk aquifer, so mains water is hard. Combi plate heat exchangers scale up, hot water temperature starts fluctuating, and unvented cylinder immersions fail early. Recognising scale as the cause rather than replacing components repeatedly saves money, and specifying appropriate scale protection at installation extends the appliance's working life considerably.
