What is actually going on with the Heatline compact combi
As a smaller-volume manufacturer, Heatline's local parts and servicing support varies more by region and installer relationship than with the biggest UK names, so it's worth confirming that before installation rather than after a fault occurs. For a straightforward one-bathroom household on a tight budget, it can still be a perfectly workable specification provided that groundwork is done.
