The price depends on the configuration and installation conditions – an EKO2 specialist prepares a quotation covering equipment, works and commissioning.
Lossnay wall-mounted mini heat recovery unit VL-50S2-E
The new, ultra-compact VL-50S2-E wall-mounted mini heat recovery unit is designed for use in private houses, apartments, offices or other small rooms where ventilation is insufficient and a ducted heat recovery system cannot be installed. For optimum ventilation, one unit is usually sufficient for rooms of up to 12–40 m².

FAQ
What is heat recovery ventilation and does my home really need it?
Heat recovery ventilation (MVHR) is mechanical ventilation in which fresh supply air is warmed (or cooled) using the energy of the extract air. The two airstreams do not mix – they are separated by the heat exchanger plates. The MITSUBISHI ELECTRIC Lossnay core is made of special paper, so it exchanges both heat and moisture.
A system usually consists of the ventilation unit, ductwork, dampers, diffusers and grilles, a controller and accessories (e.g. an electric pre-heater, CO2 sensor, silencers). In airtight new and renovated buildings without ventilation, CO2 and humidity build up, windows mist up and the risk of mould grows – this harms indoor air quality and the building itself. Our ventilation planner will help you decide what you need.
Why is heat recovery ventilation better than opening the windows?
Opening windows lets heat out in winter and heat in during summer, together with dust, noise and insects; a room is properly aired only with a cross-draught. A heat recovery system supplies fresh air continuously while returning most of the heat or coolth, so ventilation does not raise heating or cooling demand the way open windows do. The unit can be scheduled to your daily routine. The result: steady air exchange, fewer odours and less moisture, cleaner air.
My apartment lacks ventilation but ducts cannot be installed. Which unit should I choose?
In that case the best option is a wall-mounted decentralised unit that needs no ductwork. It is installed through a wall opening and does the same job as a ducted system: supplies fresh air, extracts humid air and recovers part of the heat. The Lossnay plate core also exchanges moisture, reducing window condensation and mould risk. Choose from VL-50S2-E, VL-50SR2-E or VL-80U5-E – the floor area and airflow for each are on the product page. See the comparison in MVHR or a decentralised unit for an apartment.
How much electricity does a heat recovery unit use?
Consumption depends on the model, fan speed and how many hours and in which mode the unit runs. Modern Lossnay units use energy-efficient fans, so the electricity used for ventilation is usually small compared with the value of the heat retained by the exchanger. The manufacturer's power input is listed in each model's specification, and scheduling the unit to your routine reduces consumption further.
Can a heating and cooling unit be connected to a heat recovery ventilator?
Yes. A DX coil section GUG-SL-E (for homes – GUG-01SL-E) can be connected to Lossnay ducted units together with a heat pump outdoor unit. Fresh air is then supplied already heated or cooled to the set temperature, without a draught effect. It is not a conventional air conditioner but a combination of ventilation and climate control; our engineer will select compatible models.
