About

How Does It Work?

The energiSava® 250 provides optimum ventilation for a property with a minimum loss of energy. It extracts moisture-laden air from the wet rooms such as bathrooms, WCs, kitchen and shower rooms. At the same time it supplies fresh air into the living areas (living rooms, bedrooms, dining room).

The energy from the extracted air is transferred to the new fresh air and resupplied into the property, creating an all year round, ideal indoor environment. Suitable for Kitchen + 3 additional wet rooms and achieving a maximum airflow of 270 m3/h (75 l/s), the energiSava® 250 delivers not only the utmost practicality in installation flexibility, it also performs with exceptional efficiency, achieving a low Specific Fan Power of 0.66 W/l/s.

Intellitrac® Technology

The energiSava® 250 incorporates Intellitrac® Technology, the unique humidity tracking controls. The system continuously operates at a low level to ensure that the home is correctly ventilated, providing good indoor air quality with no user intervention required.

As humidity rises and falls, the motor speed rises and falls in correlation. This controls condensation and reduces the time that the system operates on maximum speed, helping to save energy.

Peace of Mind

Manufactured in the UK and part of the award-winning Lifetime Range®, the energiSava® 250 comes with a 5 year warranty as standard. To ensure the optimum performance of the system, it is important to maintain the unit. This can be done by simply removing the front cover and accessing the exchangeable filters.

Functionality & Design

The system continuously operates at a low level to ensure that the home is correctly ventilated, providing all year round good indoor air quality.

Highly practical, the energiSava® 250 can be boosted via the switch live function or remote control to provide increased airflow. The wireless controller also indicates when the summer by-pass, frost protection and humidity tracking functions are activated.

The automatic and integral summer by-pass controls the temperature of the air entering the home on warmer days.

The easy push button commissioning pad enables the installer to correctly set the required airflow rate quickly and effectively.

Question & Answers

How does MVHR work?

Mechanical Ventilation with Heat Recovery works to ventilate the whole property by extracting air from wet rooms (kitchen, bathroom, toilet, utility’s etc.), this extraction is passed through a central unit to recover as much heat from the air as possible before pushing moisture outside. At the same time fresh air is pulled from outside passed through the central unit to warm up incoming air and filtering it before supplying air to habitable rooms (bedrooms, Livingroom’s, dining rooms etc). These two air flows do not physically mix.

Does ducting require to be insulated?

Any ducting passing through a unheated area will require to be insulated. Ducting connecting the unit to/from atmosphere will require insulating.

How often does a MVHR need servicing?

Any MVHR unit will need the filters checking at least every 6 months. It may be at 12-18 months they will need replacing. This time scale will depend largely on the environment and speed of the unit. Ideally at a 5-year period the system should be checked to confirm operation is to standard.

MVHR is noisy, running fast:

This can be dependent on what MVHR unit you have. To ensure minimal noise units must be installed as per the design using proprietary components. Systems must also be commissioned and set up correctly to ensure performance. Some units may have humidity sensors that automatically increase air flow speed to control humidity levels, therefore at times of high humidity the system will be working harder. Some units may also automatically increase in speed as filters become clogged up.

Can I turn the unit off?

It is not recommended to turn the unit off, other than for maintenance. Turning the unit off can damage the unit and invalidate its warranty. Also, by turning the unit off and stopping air movement in a property can lead to other issues, condensation, mould, smells, etc...
