The best boiler fitted poorly will underperform and fail early. Every boiler we install in Belfast includes a full system flush, magnetic filter, inhibitor treatment, and correct commissioning — not as optional extras, but as standard.
A properly flushed and filtered system protects your new boiler from the sludge and scale that are the number one cause of early failure in Belfast and Northern Ireland's water conditions.
