The launch of Grant’s first indoor wall hung oil boiler range comprising two indoor and two outdoor SEAI HARP ‘A’ rated models, is an exciting addition to the Vortex family. Available in outputs ranging from 12 -21kW in open vented system versions, the new appliances encompass Grant’s patented Vortex stainless steel heat exchanger and turbulator baffle system.

Features & benefits

All Indoor wall hung models require a separate flue kit (not supplied with the boiler) and are compatible with all Grant EZ-Fit low level, high level and vertical flue systems, so now almost any installation situation can be catered for.

Installation must comply with the current Building Regulations. As with all oil-fired appliances, Grant Condensing Boilers require commissioning at the time of Installation. This simple process ensures that the boiler is working at peak efficiency which, in turn, will result in lower running costs and long term reliability. Annual maintenance is also made easy by Grant’s cleverly designed front service access to both burner and all the internal serviceable parts. This feature enables Grant Condensing Boilers to be fitted neatly and unobtrusively within either the kitchen, boiler house, or utility room environment. Comprehensive technical information can be found in the installation manual.
