Power flushing in Larne
Larne's Coast Road and harbour terraces include some of the oldest working housing on the east Antrim coast. Many systems still have original gravity or older pumped circuits upgraded piecemeal—leaving dead legs full of sludge that no amount of bleeding clears.
Terraced harbour properties often have 6 radiators and tight boiler cupboards. Larger Coast Road bungalows may run 10+ radiators with oil-fired boilers—flush chemistry is adjusted for system type.
Coastal exposure does not change water chemistry much, but empty properties and caravan parks nearby see seasonal systems that need flushing before letting season.
BT40 covered from Carrickfergus and Ballymena routes—allow 48–72 hours in peak winter.

How long does the flushing process take?
A typical 3-bedroom semi-detached house in Larne will take our engineers approximately 4 to 6 hours. Larger properties with more than 12 radiators may take a full day.
Will it fix my cold radiators?
Yes, if the cold spots are caused by sludge buildup (typically cold at the bottom, warm at the top), a power flush will remove the blockage and restore full heat output.
