Ventilation
– Keep Moisture Out and Fresh Air Flowing In
Why Is Ventilation Important for Your Home?
A mechanical ventilation system ensures a healthier, more comfortable indoor environment by continuously replacing stale, humid air with fresh, filtered air at a comfortable temperature.
Everyday activities such as cooking, cleaning, washing clothes and using electronic devices can affect indoor air quality. Even furniture, carpets and freshly painted walls can release pollutants into the air.
One of the biggest challenges for both your home and your health is excess moisture.
A typical family of four produces around 10 litres of moisture every day through activities such as showering, cooking, washing and simply breathing.
Modern homes are well insulated and increasingly airtight, making it harder for moisture to escape naturally. Without proper ventilation, excess humidity can encourage dust mites, mould growth and, in severe cases, damage to the structure of your home.
With an efficient ventilation system, you can enjoy fresh, clean air all year round while protecting your home from moisture and mould.
If you notice more than 2 cm of condensation along the bottom of your windows in the morning, it may be a sign of excessive humidity in your home. Mechanical ventilation helps maintain balanced humidity levels throughout the year, reducing condensation and creating a healthier indoor environment.
Asthma-Allergy Denmark recommends airing out your home three times a day for 5–10 minutes, all year round, to maintain good indoor air quality.
With a mechanical ventilation system, you can enjoy a continuous supply of fresh air without having to open your windows as frequently. And with heat recovery, warmth from the outgoing air is used to heat the incoming fresh air, helping you reduce heat loss and save on heating costs during the colder months.
A comfortable indoor temperature is around 21°C.
The Danish Building Research Institute recommends maintaining a temperature of at least 18°C in every room.
Temperatures below 18°C can increase the risk of mould growth.
During winter, indoor relative humidity should ideally be between 20% and 45%.
Dust mites thrive at humidity levels of 60% and above, while levels exceeding 75% significantly increase the risk of mould growth.
Homes with lower indoor humidity are generally more energy-efficient to heat than homes with high humidity levels.

Ventilatión og hitapumpa í einum
– nú eisini við propangassi
Ein hitapumpa er av, groft greitt frá, 3 lutum. Ein kompressari, sum pressar gassi og pressar tað runt í skipani. Ein fordampapláta, sum dregur orku (hita) úr útsigvingsluftini og ein kondensatorflata, sum avgevur orku (hita) til luftina, ið verður blást inn, tá ið hon er í hitadrift. Í kølidrift verður kølikredsurin vendur og í staðin fyri at hita luftina, ið verður blást inn, kølist hon og luftin, ið verður send út hitast.
Hitaendurvinningurin nevnist COP. COP’urin sigur, hvussu nógv kW, tú fært út í forhold til orkuna í kW, sum verður brúkt í drift. Tað vil siga, at um tú hevur COP á 4, so merkir tað at fyri hvønn 1 kW streym hitapumpan brúkar, fært tú 4 kW orku úr henni sum hita. Hitaendurvinningin í eini hitapumpu kemur tí ofta upp yvir 100%.
Hitapumpan hevur ein kølikreds sum er tvígongdur, tað merkir at hon kan hita luftina útifrá um veturin og køla hana um summari.
Henda vetilatiónin hjá Nilan, er útgjørd við bæði tvígongda køliringin og eini hitapumpu. Mótstreymsvekslarin fremur høvuðsakliga hitaendurvinningina, men er ein tørvur á hiti í húsunum umvegis luftina ið blæsur inn, startar hitapumpan og førir meira hita til luftina, sum verður blást inn. Umvent, um tað er tørvur á at køla niður, vendur hitapumpan og kølir luftina, sum verður blást inn.
Henda ventilatiónin við hitapumpu larmar vanliga ikki meira enn eitt vanligt køli/frystiskáp.
Nilan hevur ymiskar støddir av ventilatión/hitapumpum. Tosa við Hita um møguleikarnar.
Streymnýtlsan valdast nógv av hvat tú velir og eisini hvussu ventilatiónin/hitapumpan verður brúkt. Streymnýtslan til hitapumpuna valdast eisini av tínum hita- og/ella kølitørvi. Tosa við Hita um hetta.
Nilan ventilation/hitapumpa hevur vanliga livitíð á meira enn 20 ár.
Tosa við Hita um viðlíkahald, filtur og um serlig filtur til ovurviðkvæmi.
Í løtuni (2022) fært tú endurgoldið mvg við keypi og uppsetan av ventilatión/hitapumpu (jarðhita og luft til vatn).
