Helios System with Heat Recovery(MVHR)
A Helios System with Heat Recovery (MVHR) is a decentralised ventilation system which efficiently recovers heat from all ventilation units which are strategically positioned around your home. Helios KWL heat recovery units are installed in exterior walls, requiring no ductwork throughout your home! This is just one of the many benefits of Helios ventilation systems. These systems are suitable for new build and retrofit applications alike.
The Helios KWL Heat Recovery unit is an ideal ventilation solution for your home. Helios KWL fans generally operate in pairs but can also operate in uneven numbers. Therefore, an even number of units must always be installed in a property to ensure the units work properly.
How the Helios KWL works…
At first, it extracts air whilst absorbing the heat within the unit’s core. When the core is fully charged with heat, the fan changes direction & draws fresh, filtered air, from outside through the unit and into the room, whilst transferring the stored heat into this fresh air. Each Helios KWL unit is wired together with another, and whilst one unit is extracting, the other is drawing fresh air inwards – and vice versa. The Helios KWL fan with heat recovery has a tiny power consumption resulting in electricity costs of only a few Euro per annum!
Because Helios Heat Recovery units operate in pairs, air within the home is kept balanced at all times and without risk of this getting altered. On account of the decentralised concept, the individual fans can be installed exactly where they are required. There are no ducts to be installed, meaning a simple installation process for both new-build and retrofit. In the case of an uneven number of units being installed, your commission technican will set up your system to ensure that the incoming air exactly balances with extracted air.
Helios ELS and M1 highly efficient exhuast units are installed in wet rooms to provide extraction of moisture on an "on-demand" basis. This means that these exhaust units are only utilised when the wet rooms are actually in use. So, although the exhaust units don't offer recovery of heat, because they are only used periodically, the overalle efficiency of the heat recovery system is only reduced by 1 - 2%*.
This way, heat is recovered from the vast majority of air exchange, but cost is significantly reduced by utilising the less expensive Exhaust Air units in the wetrooms.

I am very pleased with the outcome of the external insulation job on my house, completed by Comfort Solutions. It has put a very modern finish to the house and has blended in very well with the new extension but most importantly it is very efficient in heat retention.

Additionally, we suffered from water penetration... Read more

External Insulation
In the Spring of 2013, Comfort Solutions installed external wall and loft insulation at the home I had recently bought. Before the installation, I had been concerned at how quickly the house could become cold and damp.
