The energiSava 400 is a high efficiency whole house heat recovery system providing all year round good indoor air quality and a healthy enviroment.
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 400 whole house heat recovery system. 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.
The energiSava 400 heat recovery system is ideal for residential properties to provide a constant supply of clean, tempered air and maintain stable humidity levels. With a maximum airflow capacity of 400 m3/h, they are available in left-handed and right-handed versions with a range of options for connecting the ducts. In addition to the comprehensive standard version, a ‘Plus version’ is also available which offers additional connection options, such as a CO2 sensor.
As building efficiency is improved with wall and loft insulation, draught proofing and double glazing, buildings are becoming more air tight and are consequently less well ventilated. Good ventilation is vital to our health and the fabric of our homes. Opening windows is one option, however this is not ideal due to security risks, loss of heat and energy in colder months.
To solve these problems, heat recovery ventilation, covered under System 4 of the Building Regulations Approved Document F: Ventilation, can provide fresh filtered air, energy efficiency and a comfortable all year round climate for your home. Stale, moist air is extracted out of the wet rooms of a home. These include the kitchen, bathrooms, utility and en-suite rooms. This moist air is then ducted to a central unit located normally in a utility room in a house or cupboard in an apartment.
This extracted air passes over a heat exchanger before being ducted to outside. Simultaneously, fresh air is drawn into the unit from outside, and is warmed by the high efficiency heat
exchange cell. This tempered, fresh air is then delivered through supply vents into the living, dining and bedroom areas.
This constant supply of clean, tempered air into the property creates a healthy and ideal environment, maintaining stable humidity levels, free from condensation and mould. Sufferers
of asthma, house dust mite populations and other respiratory problems should find this method of ventilation significantly beneficial.
The energiSava® 300 & 400 products are Passive House certified and manufactured with the latest energy saving technology. The Passive House concept is the only internationally recognised, performance-based energy standard in construction.
The energiSava 300 and 400 units come as standard with bypass and preheater. 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.
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.
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.
Engineered with aerodynamically-designed fans to run at lower rates enables noise to be reduced and minimalised, whilst lower internal resistance delivers exceptionally quiet running.
The energiSava 300 and 400 units 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 and/or the 2-zone demand flow system enables automatic ventilation control and saves even more energy.
