iHelios heating systems – helping prevent condensation and mould

iHelios heating systems – helping prevent condensation and mould

Damp and mould issues are quite common in UK households and other types of buildings. They should not be overlooked, as they are much more than annoying and unesthetic trouble, but also related to health issues: “Damp and mould in the home can cause respiratory problems, infections, allergies, and asthma, and it can also affect the immune system” (Damp or Mould: Knowing the Difference | Archer Specialist Treatments ( They can also lead to serious structural damage to the building. Considering how hazardous for our health and damaging for our properties damp and mould are, it is a clear conclusion that they should be treated promptly. iHelios heating system can come in handy here, but before we get into explaining how iHelios heating system helps to prevent and reducing dump and mould problems, some attention should be given to clarifying what damp and mould are, what are their causes, and what is the difference between them.

Generally speaking, damp can be described as the presence of excessive and unwanted moisture in our properties. Based on its origins, appearance, and treatment, damp can be classified into three main types: condensation, rising dump, and penetrating damp. 

Condensation, which is the most common type of damp, occurs on surfaces when there is too much moisture in the air and when the warm air encounters a cold surface. As a result, the air’s temperature drops quickly and the moisture in the air turns into water droplets that settle on the surface. Condensation is more common in winter when our heating systems work hard to heat the indoor air while leaving the walls cold. 

Rising damp, the second type of damp, usually affects ground floor walls and is caused by water from the ground finding its way up into our walls or floors. In most cases, a damp-proof membrane installed in our walls creates a barrier for the water, but in some cases, it may get damaged with time or external ground level may be raised above damp barrier and the water finds its way through the walls. Finally, penetrating damp is caused by water leaking through walls and roof due to structural issues in the building – such as cracks in the walls, leaking roof, or faulty guttering, as well as internal leaks from pipes. 

All kinds of damp, if left untreated, can encourage the growth of mould and cause health problems and damage to the building. Mould group, which belongs to the fungi family consists of diverse and numerous species that grow on different surfaces. The one that we focus on in this blog is household mould, which targets the buildings, grows especially well in a damp, humid environment with poor ventilation and a low level of light. It usually appears in bathrooms, basements, and around the door and windows. 

iHelios heating system emits far-infrared radiation, which does not heat the air. Instead, it travels through the air and directly heats the objects – walls, ceilings, floors, furniture, and living organisms. Radiant heat is especially well absorbed by water, which means that any areas affected by damp and condensation will absorb the heat and dry up as a result. This reduces damp in the building. We can observe a similar process when the infrared radiation emitted by the biggest and natural sources of infrared – the sun – dries up wet laundry on the washing line in the garden. iHelios heating systems can do more than that – it not only heats and dries the wet areas, but it can also prevent condensation from occurring. Convection heating systems, that heat the air while leaving the walls and objects in the room cold, create perfect conditions for condensation to form. iHelios heating system, on the other hand, heats the objects and surfaces. They absorb and retain the heat and stay warm for a certain time (even when the original heat source is off). At the same time, the air that is not heated by the infrared rays remains cool. Warm walls, ceilings, and windows together with cool air create an environment in which condensation and mould are less likely to occur.

It is worth mentioning that – like with most issues – the problem should be tackled from many fronts and with all the relevant causes identified and addressed. If there are deeper, structural issues that result in raising or penetrating damp, they will continue to let the water in and, obviously work against iHelios efforts to dry wet areas. In such cases, any attempts to dry and ventilate the space will be more of patching up sorts than getting to the routes of the issue. Structural failures should be eliminated first to achieve the best results. At last, even with the good insulation and glazing, structural failures eliminated, and infrared heating system working against the condensation and mould, accurate ventilation of the building and changing the indoor air is always recommended too. Speaking of that, iHelios system that does not heat the air, and which is equipped with an open window sensor, encourages ventilation by reducing heat loss associated with it.
