There are two boilers, with outputs of 24 and 30 kW and offering a 5 s response to demand for hot water. They deliver 9.6 and 12.3 l/min, respectively, through a 35 K temperature rise. Both units are 700 mm high, 390 mm wide and 280 mm deep. They have SEDBUK A rating.
The small size of these boilers is made possible by using high-grade cast aluminium for the heat exchanger, a material that has excellent thermal conductivity.
The direct rear flue is telescopic, so there is no need to cut to length.
A fixing jig ensures the hanging bracket and jig are perfectly aligned. The design of the pre-fixing kit allows pre-installation and system testing before the boiler is connected. All copper tails are clip distance from the wall for easy connection to system pipework.
A pull-out block for electrical connections eliminates the need to remove the front casing during installation or commissioning. These boilers can also be installed with volt-free controls, so that Part P approval is not required.
An optional condensate pump enables cx boilers to be installed in places with restricted access to a drain.
