How does it work? The energiSava 210 works by extracting stale, moisture-laden air from the wet rooms such as bathrooms, WCs, kitchen and shower rooms, which is released into the atmosphere. At the same time it supplies fresh, filtered air into the living areas. The energy from the extracted air is transferred to the new fresh air through the high efficiency heat exchanger before being re-supplied into the property.

With a mechanical extract ventilation system, the new air would enter at 2ºC through the air inlets, decreasing the internal temperature of the home. With the energiSava 210, the supply air would enter at 19ºC.
The energiSava 210 is a low energy whole house heat recovery unit with a high-efficiency heat exchanger to provide a constant supply of fresh tempered air into the living spaces of a home.

With a mechanical extract ventilation system, the new air would enter at 34ºC through the air inlets, increasing the temperature inside home. With the energiSava 210, the supply air would enter at 24ºC and it will avoid the rising of interior temperature.

In addition, during summer nights, when the outdoor air is colder than the indoor air, the bypass is activated automatically avoiding he mixing of airflows and supplying cooler air to the home.

Very compact
Incorporated within the energiSava 210 is the intelligent humidity tracking control as standard, which constantly monitor the humidity level, meaning no user intervention is required. As humidity rises and falls, the motor speed rises and falls in direct correlation. This controls condensation quietly and efficiently, reducing the periods of time when the system operates on maximum speed, saving energy The intelligent filter change indicator notifies the user when these need replacing.
Easy access to filters
Easy access to internal elements
The innovative control switch allows the user to select: The airflow rate Holiday mode Summer by-pass It also indicates when the filters needs replacing.

Heat Recovery Efficiency (%)
Motor Incorporates the Ultra Low Watt EC motor technology with sealed for life ball bearings designed to operate continuously at a pre-set ‘background’ rate. Fans The unit shall incorporate two high performance forward curved continuous running fans. Heat Exchange Cell The heat exchange cell within the unit shall be a counter-flow, multi plate heat exchanger manufactured from Polyethylene (PE) and shall be designed to deliver up to 89% efficiency. Construction The construction of the casing shall be out of EPP moulding. Filtration There shall be filters incorporated into the unit to protect both the extract and supply air. An M5 filter (optional f& filter available) shall protect the supply airflow with a G4 pre-filter. A G4 filter shall protect the extract airflow. Controls The unit shall be controlled using a hard wired boost switch capable of selecting the airflow rate, holiday mode and summer by-pass. The unit shall also incorporate the intelligent and humidity tracking controls. Maintenance/Servicing The unit shall require cleaning/replacement of the filters located within the unit every 6 to 12 months depending on conditions of use, location etc. The remote control module will indicate when the filters should be replaced. These are located in the front of the unit within easy access for the user. The motor, fan and heat exchange cell shall require a service check once every 5 years. This is enabled by removing the front cover and cleaning any dust away with a dry brush. Accreditation SAP Appendix Q eligible
