Condensing boiler has output of over 1 MW

Viessmann, Condensing boiler, district heating

Viessmann has added a new model to its line of Vitocrossal 300 gas-fired condensing boilers for heat outputs ranging from 780 to 1400 kW. These boilers are well suited to systems with large water volumes such as district-heating networks, schools, hospitals and other buildings with large radiator coverage or underfloor heating systems.

The boiler’s open waterways and doubled output over the previous model means there is no need to purchase cascade/add multiple products. The new boilers is said to be about £2300 a year cheaper to run than two 311 kW Vitocrossal boilers or their equivalent.

This boiler is one of the largest single-unit condensing boilers in the UK and features a Inox-Crossal heat exchange and a second return connector for low return temperature down to 30°C.

A seasonal efficiency of up to 98% can be achieved, and, unlike boilers with aluminium heat exchangers, there is not minimum flow rate — so there is no need for primary shunt pumps and low-loss headers.
