Installer Due Diligence for Changeovers
Modern ducted gas heaters, even those that are physically 'like-for-like', typically have different technical specifications
and control systems to existing, older models. Modern units usually have higher Star Ratings, which are accompanied
by higher airflows. Higher efficiency heaters with modulating gas valves also operate differently to non-modulating
units.
When doing a direct unit change over:
•
Do a comprehensive inspection of the entire existing system to ensure it is 'fit for purpose' with the new heater
•
Check existing items that are not being replaced; i.e. ensure the soundness and suitability of all fittings and
controls for use with the new ducted gas heater (e.g. Duct sizes, Flue, Return Air grille size, Thermostat, Zoning
etc.)
•
Correctly commission the new ducted gas heater – where possible, align it with the performance characteristics
of the original system – do not leave units at the factory default settings unless you are absolutely certain the
settings are appropriate
Failure to observe best practice can lead to costly call backs for installers, unnecessary manufacturer warranty calls
and a poor customer experience.
With our policy of continuous improvement, we reserve the right to change, or discontinue at any time, specifications
or designs without notice.
