Comfort, simplicity and performance
Elexia the instant solution
The Elexia comfort range has been designed to respond to modern household demands at the flick of a switch.
Hot water for the bathroom
The Elexia comfort heats water instantaneously, to provide a limitless supply of hot water around the home. With no need for header tanks or hot water cylinders it saves energy and permits an easy installation.

Heating around the home

Full electronic control provides a stable temperature output for heating systems. Clear controls make it easy to maintain the perfect temperature. From installation to daily use, the Elexia comfort range has been developed to make life easier: - Easy to use temperature controls for both heating and hot water give precise adjustment at the owners finger tips. - Optional room thermostats have been chosen for clarity and adjustability.

The Intelligent solution

An on-board computer and state of the art controls protect the owner, the system and boiler from harm. The Elexia comfort constantly monitors its own systems to warn of component failure or problems in the system such as blockages. The computer also works to protect the boiler from frost damage and the pump from seizing during the summer months. Should a fault occur, the unit indicates the type of failure, helping the service engineer to fix the problem quickly.

Designed for simplicity

Simple to install
The Elexia comfort comes factory set ready for installation, with many features to assist the heating engineer and save time and money on site. A complete package includes pre-installation jig, copper tails, power fly lead, easy fit flue and optional pipework changeover kits and simple plug-in time clock. The Elexia comfort can be used with 5 flue options, providing flexibility in choice of location. Pipework can be run up behind the boiler without the need for a separate spacer kit, allowing pipes to be hidden from view. All components can be reached from the front of the unit for maintenance, allowing the unit to be easily installed between kitchen cabinets. As no compartment ventilation is required the Elexia comfort is also perfect for locating inside cupboards.

Maximum reliability

The key areas of the boiler have been designed to provide maximum reliability. With fewer moving parts and no restrictions in waterways, reduced stress on key components ensures an extended working life. Advanced composites are used to construct key areas of the boiler, to avoid joints and allow for a compact design.
