Benefits

Bosch Singular Boiler Applications

Singular combi wall boilers provide efficient heating and plenty of hot water for many residential applications. There are two different models to choose from: 155K BTU and 199K BTU. Both can make enough domestic hot water for most residential bathing needs.

Superior Design & Components

Depending on inlet water temperature, the 4000 can run between 2 and 3 showers and the 5200 can run 3 showers plus a dishwasher. There's plenty of endless hot water available with Singular. Both models have a small footprint and are under 80 pounds, making installation a breeze. Features like an exhaust gas outlet sensor and a standard inlet filter screen to keep out debris provide extra protection for the boiler.

Residential Limited Warranty

Receive peace-of-mind knowing you will have a 10 year heat exchanger, 5 year parts, and 1 year labor limited warranty. This standard offering covers the components incorporated into the Singular boiler at the time of manufacture.
