Power flushing in Donaghadee
Donaghadee's harbour-side terraces and 20th-century semis along the coast road to Millisle often run heating systems that have been topped up from the header tank for years—introducing oxygen and rust. Second homes and retirement bungalows are frequent customers before the first cold snap.
Smaller properties with 5–7 radiators are typical; flush times are often half a day. Larger 1930s detached homes on the coast may have dual zones that need balancing after sludge removal.
Properties closed over winter need a flush more than inhibitor alone—stagnant water accelerates internal rust even when the boiler is off.
BT21 fully covered from Ards-based engineers. Seafront parking is manageable for portable flush units.
