Why Choose the Bosch Highflow C21 Hot Water System?
The Bosch C21’s unique condensing system makes it more energy efficient than your standard non-condensing hot water system because it uses a second heat exchanger to preheat the incoming water.
Through this unique system, the Bosch C21 harnesses the excess exhaust gas in the secondary heat exchanger to minimise energy loss. The Bosch C21 has an impressive 6.9 star energy rating which makes it one of the most energy efficient continuous flow systems on the market today.
Despite its small size, the Bosch C21 hot water system can provide an impressive 21 litres of hot water per minute, meaning that you’ll never be without hot water! Like all continuous flow hot water systems, the Bosch C21 is significantly more energy efficient than standard storage hot water systems, as they only heat water when required.
For ease of installation, the Bosch C21 can be ordered in both natural gas and LPG gas models. This way you don’t need to make any alterations to your gas supply just because you’re installing a new hot water system.
