What is pluming?
Condensing boilers, such as the Grant Vortex, operate at extremely high efficiency levels, producing cool flue gas temperatures which result in a ‘plume’ of vapour being visible at the flue terminal. This plume (steam) is a normal condition of condensing boiler operation and indicates that the appliance is working efficiently.
Prior to installation, the position of the flue needs to be considered to ensure that the plume does not cause any inconvenience. Grant EZ-Fit flue systems are designed to ensure pluming is kept well out of the way of any windows, air vent or doors, and out of sight. Read more about flue systems from Grant UK here.

Case Studies
Grant boilers combine choice, quality and service to be an installer’s favourite oil boiler brand
G1 Installers, Marshall Heating Ltd, completed the installation of a Grant Vortex Eco Utility oil boiler in the village of Benenden, Kent, in October this year and we caught up with them to discover more about why this boiler, and Grant’s other Vortex and VortexBlue models, are the preferred brand of oil-fired boilers for this installer.
Grant Solar Thermal system and thermal store partner up with VortexBlue oil boiler
In 2019, a large property in Llanfyrnach, Pembrokeshire underwent a complete refurbishment which included upgrading the heating system. Today, the home’s heating and hot water requirements are being met more sustainably by a bespoke hybrid system consisting of a Grant Solar Thermal system installed alongside a VortexBlue oil boiler.
