What is Heat Recovery? 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 of a home. These include the kitchen, bath, utility and en-suite. This moist air is then ducted to a central unit located normally in the loft space in a house or in a utility room 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 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. Passive House Certified The energisava 300 & 400 products are Passive House certified and manufactured with the latest energysaving technology. The Passive House concept is the only internationally recognised, performance-based energy standard in construction. Your first choice for ventilation
Silent Running Engineered with aerodynamically-designed fans to run at lower rates enables noise to be reduced and minimalized, whilst lower internal resistance delivers exceptionally quiet running. Control Options 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. 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.
