About

Future-proof

Providing all year round good indoor air quality is vital for a healthy and comfortable living environment. Regulations relating to energy efficiency and low noise levels are becoming increasingly stringent.

EnviroVent have responded with the introduction of the energiSava® 300 & 400 Series. These high efficient whole house heat recovery products have been designed not only with the optimum performance for today’s requirements but with forward-thinking innovation for future demands in ventilation.

Summer Bypass & Frost Protection

The energiSava® 300 comes with bypass and preheater as standard. The bypass contributes to an improved comfort level in summer and is controlled automatically by measuring indoor and outdoor temperatures. The intelligent frost protection with preheater guarantees the high efficiency, even at extremely low temperatures. This energy-efficient frost protection helps to achieve significant energy savings per year.

Constant Flow Control

The ‘constant flow’ technology ensures maximum efficiency and that the commissioned airflow rate is always delivered despite any resistance encountered in the ductwork or filters. The ‘constant flow control’ system also enables commissioning to be carried out much quicker and more easily, saving on installation costs.

Silent Running

Engineered with aerodynamic fans to run at lower rates enables noise to be reduced and minimalised, whilst lower internal resistance delivers exceptionally quiet running.

Control Options

The energiSava® 300 unit can be controlled with a 4-way switch with filter indication or a wireless remote control. Alternatively, using the intelligent control module with timer, or the relative humidity sensor.

Passive House Certified

The energiSava® 300 products are certified by the Passive Haus Institute and manufactured with the latest energy-saving technology.

The Passive House concept is the only internationally recognised, performance based energy standard in construction.

Ease of Maintenance & Commissioning

The units come as standard with two G3 filters that can be easily changed. These filters remove 95% of the dust from the air.

A high-performance fine dust filter (F7 filter) is optionally available, ideal for people with respiratory conditions or allergies. The intelligent digital display panel located on the unit ensures the utmost ease of commissioning.

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...
