Series Saunier duval - ISOFAST CONDENS

Saunier Duval - ISOFAST CONDENS

The Saunier Duval ISOFAST CONDENS series is built for modern heating systems where efficiency, reliability, and fast installation matter. Designed specifically for professional installers, this condensing boiler range delivers consistent performance while keeping setup time and long-term maintenance to a minimum. Whether you are upgrading an older system or fitting a new residential setup, the ISOFAST CONDENS line gives you the flexibility to match the right unit to the job.

High Efficiency and Real Energy Savings

Condensing technology captures heat from exhaust gases that would normally escape through the flue. The Isofast 21 Condens T26-CS/1 model takes advantage of this process to reach top seasonal efficiency ratings. When paired with the SRC 720 MiPro Sense system controller, the boiler adjusts its output based on outdoor weather and indoor demand. This smart modulation cuts fuel use, lowers utility bills for end users, and helps you meet strict environmental standards without extra hardware.

Installer-Friendly Design and Quick Setup

Every unit in this series is wall-mounted and compact, making it easy to fit into tight utility rooms or cupboards. The Isofast 21 Condens T26-CS/1 comes in two practical versions: a standard condensing boiler and a two-function model with a built-in domestic hot water tank. Both feature pre-wired electrical connections, clearly labeled terminals, and a streamlined gas and water layout. You can mount, connect, and commission the unit faster, which means fewer site visits and happier customers.

Built to Last with Simple Maintenance

Installers know that call-backs kill profit margins. The ISOFAST CONDENS series uses a robust stainless steel heat exchanger that resists corrosion and handles hard water better than traditional materials. Service panels open wide for quick access to filters, pumps, and control boards. Routine checks take minutes, not hours, and replacement parts are widely available. This straightforward design keeps the system running smoothly for years while protecting your reputation.

Complete Heating Control and System Compatibility

Modern homes need precise temperature control and seamless integration with existing radiators or underfloor circuits. The Isofast 21 Condens works smoothly with the SRC 720 MiPro Sense controller, which learns your building’s thermal behavior and optimizes firing rates automatically. It also supports standard plumbing connections and can be linked to additional solar or heat pump systems if needed. Choose the right variant, connect the controller, and deliver a complete, future-ready heating solution.
