Saunier Duval Thelia boiler installation by qualified engineers
Our Saunier Duval Thelia boiler installation service is designed for homeowners, landlords and residential property managers. We confirm the exact appliance from its data plate before attendance, because controls, components and test requirements vary between models and production years.
The engineer considers the complete heating installation: boiler condition, gas supply, flue, combustion, safety controls, circulation and user controls where relevant. That evidence-led process helps distinguish an appliance fault from a system or control problem and avoids unnecessary parts replacement.
Saunier Duval Thelia is an older model range. We assess the existing system and specify a suitable current replacement rather than claiming to supply a discontinued boiler.
