Genesis Eco

Electric boilers

The Genesis Eco range of floor standing electric boilers is an excellent option for commercial properties. With outputs from 36 to 504kW and efficiencies up to 99.9%, the boilers can be utilised as the primary heat source or as a secondary heat source when working with heat pumps on a hybrid system. This facilitates improved system efficiencies, reduced capital investment and space requirements, plus flexible system design.

Modulating heat output

Multiple integrated stainless steel heating elements allow variable output. Depending on the model up to 24 steps of operation can be controlled automatically by the boiler or externally via receipt of a 0-10VDC signal. A limitation on the number of steps to be operational is also possible. Modulating control is especially important on hybrid systems where electric boilers are to work together with other heat sources such as heat pumps on modern low temperature heat networks (LTHNs).

Easy controls

The boiler features an easy-to-use touchscreen control, allowing simple installation and commissioning, as well as straightforward monitoring and servicing. This includes easy access to operational parameters such as power output and operating temperatures - all of which are also accessible via Modbus compatible connection.

Note: The nominal water flow rate (∆T 10°C) is recommended | Good practice advises that the boiler circulation pump (not supplied with boiler) is installed on the return pipe and be speed controlled in line with the output required of the boiler, in order that the design delta T is maintained. The minimum output of the boiler can be fixed to match the modulation capability of the pump which is usually not as low as the boiler is designed to achieve. The boiler is not able to control the pump speed so the BMS or other should provide the facility.
