Bosch C21

Jim’s Plumbing can service, repair and replace your Bosch C21 hot water system

The Bosch C21 is a condensing gas continuous flow hot water system that is perfect for delivering efficient and dependable hot water to your house or property. The Bosch Condensing C21 is Bosch’s more environmentally friendly answer to hot water solutions and because of its economical nature will save you countless amounts on your energy bills. It’s the perfect option for your next hot water system.

Bosch C21 Condensing Technology

Bosch utilises advanced technology with the C21 that allows it to be far more efficient and economical than other hot water systems, both saving you money and saving the environment. The condensing technology means that the heater captures additional heat that other systems would waste via flue gasses by the use of a secondary heat exchanger. It takes this bi-product and turns it into more energy to heat your water. This means the C21 is 90% more efficient than some other heaters. This is reflected in the near perfect 6.9 star energy rating (out of 7 for those who don’t know). How good is that!

Bosch C21 Features

For a general overview of some of the Bosch C21 features, here is a list of what to expect…
– Delivers 21 litres of hot water per minute

– 6.9 star energy rating
– Suitable for smaller homes between 1-2 bathrooms
– External installation
