Concern & action: Condensing Plume location
The location of the exhaust water vapour plume of a condensing boiler needs careful consideration to avoid dampening surrounding fabric and prevent water vapour entering the loft via the eaves
Consider at design stage the position of the boiler exhaust and its surroundings, including the moisture handling properties of nearby materials.
Locate (or relocate if need be) the boiler exhaust in a position that avoids the condensing plume constantly hitting the surrounding fabric.
Monitor the conditions post-installation in proximity to the exhaust and carry out regular visual checks to look for signs of damage/decay. Relocate the boiler if continuous high moisture content recorded in surrounding materials or early signs of damage spotted.
