Air and Heating Systems Install and Supply

Energy label A++

High performance air/heat pump

Developed for the Nordic climate

Modern and neutral design

Our systems is specifically designed for the tough Nordic climate making them top energy and efficiency rated. AA 5.5 Performance is the heat pump that delivers plenty of warmth and provides significant cost savings during the whole heating season and when it is coldest outdoors. The heat pump has a high-performance variable-speed compressor and is also equipped with the very latest technology in heat pump field.

AA 5.5 Performance of the ES has a variable speed compressor that automatically adjusts the output when the heat demand changes. Defrosting is done automatically and is upon demand. The energy efficiency is very high a high, just like the cost saving.

Very high Seasonal Efficiencies

Seasonal efficiency belongs to top of the class. The SCOP is a way of showing how effective the heat pump is in heating mode in all over Europe. There are three different climate zones in Europe according to the testing and accordingly three different Seasonal data, so be sure that you check the SCOP to your climate zone.The Nordic countries belong to the cold climate (cold/C), apart from Denmark belonging average climate (average /A).

Large parts of eastern are also in the cold climate zone. Ireland is in the warm climate zone. Seasonal efficiency gives an idea of the heat pump’s efficiency over the entire heating season with varying outdoor temperatures and is an important parameter for the purchase of a heat pump. AA 5.5 Performance has SCOP A of 4.7 and SCOP C 3.7. In practice this means that savings of this heat pump is extremely high, and few if any heat pumps has a shorter payback time

Features and Benefits

The Mitsubishi Lossay units come in a wide range of models with airflows from 250 to
2,000m3/h and offer the following benefits:

Highly Efficient Heat Exchanger with the following Benefits

Compact Design

The slim design of the Lossnay units make them one of the most compact in their category

Low Noise Level

  • Fresh air supply for indoor environments
  • Energy recovery ventilation between supply and extract air supplies (forced energy
    exchange mode) efficiencies up to 80%
  • Automatic Ventilation (KPI controls which mode to operate within to achieve maximum
    energy efficiency)
  • Air filter
  • As a consequence of the energy exchange during the summer period, the cooling load can
    be reduced by up to 20%, minimising both capital and running costs


Easy access hatches for the heat exchanger, motor, fans and electrical box allow in situ maintenance

Standard Controls

Hard wired remote controller with built in 7-day timer
