Figures from the Saunier Duval data sheets. For a flat with one bathroom, a boiler of about 24-26 kW for hot water is usually enough; with two bathrooms, 28-31 kW is better. We confirm it from photos of your installation.
What’s included in the installation
- Removal of the old boiler.
- Fitting the new boiler and connecting it to the gas, heating and condensate drain.
- Commissioning and handover of the paperwork.
- 5-year written warranty on the installation.
A boiler replacement is usually done in one day. If the flue or the circuit needs adapting, we tell you beforehand from a few photos on WhatsApp; a free visit only if needed.
