Ecodan Technical Data

The Edcodan Range

The comprehensive Ecodan range is designed to suit a wide number of applications, from a small flat to a six bedroom house and will cater for the varying requirements of both new build and existing homes.


The smallest capacity unit in our Ecodan range is the W50 which is 5kW and is perfect for use in new build applications due to their modern day thermal efficiencies. Able to work at variable capacities between 1.5kW and 5.2kW the W50 is ideal for many applications ranging from smaller existing homes or flats to medium sized newly built homes.


Currently the popular unit in our Ecodan range is the W85 which is proving ideal for use in both newly built homes and existing homes too. Able to work at variable capacities between 3kW and 9kW the W85 offers the widest scope to cater for the majority of applications


Catering for applications with a greater demand for a more powerful unit is the HW140. With the potential to operate between 5kW and 14kW, our most powerful unit is perfectly suited to provide effective heating and hot water for larger, existing homes that do not benefit from the thermal efficiencies of today's homes. This unit is also available as a 3-phase option

Flow Temperature Control

The Ecodan controller is specifically designed to ensure that space heating operates at optimum efficiency. The controller is also designed to readily interface with standard S plan central heating and hot water systems to enable Ecodan to be used with other suitable hot water tanks and under floor heating systems.

To combat the ineffective ‘On/Off’ approach of heating systems, our inverter driven technology means we can offer Flow Temperature Control. Put simply, this enables the system to vary the flow temperature of water depending on the demand for heat - quickly reacting to outdoor weather temperatures and making it hugely energy efficient. Here are some examples of the features our control systems can offer:
