The Geminox ZEM Merite range is designed specifically for the domestic heating market, comprising of 4 models, the 2-17C and 5-25 C system boilers, the 5-25C B120 combined appliance and the 5-25 SEP (see combination boilers).There is a choice to suit applications from a studio flat to a large modern home. As standard all models come complete with in-built weather compensation and each model is supplied with an outside sensor to encourage use of the technology.

There are 2 system boilers which can be used for heating only or heating and hot water applications when used with our EBS hot water tanks. The system boilers are available in 2 outputs, the unique 2kW-17kW and the 5kW-25kW model.

Use of our diverter valve and hot water sensor activates the dual modulation of the ZEM boilers. The boiler will then fire at full power i.e 17 kW for the 2-17 version or 25 kW for the 5-25. After the hot water is satisfied the boiler will then modulate between either 2-17 kW or 5-25 kW depending on the heat requirement of the property based on the information from the room unit and outside sensor.

Our simple control kit wires back to the boiler microprocessor making installation and use easy. All boilers can be connected to our unique cascade flue systems.
