Dry out the cellar yourself – infrared heating is used
In order to make the basement rooms of our over 100-year-old city villa usable, I first have to dry them out. The house is partially built into the slope. On the east side the basement floor is at ground level and on the west side about 200 cm below ground level.
I have already used various methods for draining. I am currently creating a new watertight horizontal barrier in the masonry using chemical agents such as injection liquid, injection sticks and injection cream.
I have already drained the eastern part of the cellar. Now it is the turn of the western part of the building. This time I let my camera run along to shoot short video footage for my“Drying out the basement” playlist.
But also here in the construction diary I would like to document the individual steps.
Workshop in damp basement
Over the winter I dedicate myself to the development of the basement rooms so that they become usable. A room of about 36sqm is to be converted into a workshop as my current workshop is simply too small.
Unfortunately, the basement is very damp and clammy and I fear that my tools and building materials would sooner or later suffer enormous damage. Therefore, it is only logical that I also completely dry this cellar first.
Here, as in other basement rooms, I relied on the injection method. In this process, a liquid is introduced into the walls so that they no longer absorb moisture.

Draining the cellar – interim result after three weeks
For 3 weeks, the injection fluid for masonry drying has been flowing into the walls. The bottles were now completely refilled with the injection solution a total of between 4 and 5 times.
As I wrote in the last post, I have now switched to not refilling the bottles daily. Instead, I just fill up the empty bottles. This way I can better monitor the saturation of the masonry.
In the meantime, there are also the first results. My measuring instruments are already showing the first changes. The humidity is slightly lower and the moisture in the bricks has also subsided.
Certainly, the results are highly dependent on room temperature and ventilation behavior, but a trend is emerging.

How does an infrared heater work?
An infrared heater works by emitting infrared radiation, which heats objects and people in the room directly instead of heating the air first.
Technically speaking, the heater converts electrical energy into infrared rays which, like sunlight, release heat when they hit surfaces.
This results in a direct and efficient heat source without unnecessarily circulating and swirling up the air.
The advantages of infrared heating are the rapid heat build-up and efficient room heating. As there is no air movement, less dust is stirred up, which is particularly beneficial for allergy sufferers.
In addition, infrared heaters are low-maintenance and easy to install. They are ideal as additional heating or in rooms that are not used continuously.
However, there are also disadvantages.
Infrared heaters can be more expensive to purchase and are less efficient in large or poorly insulated rooms as they do not heat the air directly. High ceilings or open rooms can thus become a challenge.
The efficiency of infrared heating can be increased by combining it with good room insulation and targeted use in smaller, well-defined areas. This helps to minimize operating costs and maximize the efficiency of the heating system.
With regard to wall moisture: using infrared heating can actually help to reduce moisture in walls.
In my case, I used the infrared heating in the cellar to dry damp walls by pointing the heating directly at the wet wall.
The heat from the infrared rays penetrates the wall and increases the local temperature, which promotes the evaporation of moisture.
This can be an effective method, especially in poorly ventilated or cooler basements, to regulate wall moisture and prevent mold growth and structural moisture damage in the long term.

Use infrared heat for masonry drying?
At the beginning of the drying process, I had used my dryer and also my fan heater to assist. I had placed both devices directly in the direction of the particularly damp corner of the house.
In my opinion, the dry and warm air definitely favored the absorption of the liquid through the walls. The bottles emptied much faster at warm room temperatures than at cold temperatures.
However, this method has one major drawback: the electricity meter!
While the dryer makes do with just under 500 watts per hour, the fan heater uses between 1,600 and 3,200 watts per hour. In continuous operation, costs of 15 euros per day or even 450 euros per month quickly add up.
So, despite PV system, it was not a solution.
So I put an infrared heater on the wall. The model I use requires only 600 watts per hour. In 24-hour continuous operation, this would cost a good 4 euros, or 120 euros per month.
That was still a lot of money, but definitely less than the 450 euros with the fan heater and dryer.
But would this solution be of any use? – In a nutshell – No, it’s no use!

Why infrared heating failed
Unlike a classic heater, the infrared heater does not work with convection heat. Thus, it does not radiate heat in the actual sense as does a stove or a normal radiator.
Infrared heating, as the name suggests, emits radiation in the infrared range. This radiation itself has no “heat”. But the irradiated materials are excited by the radiation and slowly heat up.
In this way, the illuminated wall or the illuminated door itself becomes a heater which then emits convection heat. Decisive here is certainly also the thermal capability of the illuminated object.
Obviously, the amount of energy from the infrared radiation was not enough to heat the walls. The water content in the masonry was probably simply (still) too high.
Or in other words, the performance of the infrared heater was simply too weak.

Next steps to dry the basement
I am writing this post a good year after the actual test with infrared heating. So I can draw a conclusion quite well in the meantime.
I have since refrained from taking any additional measures. The cellar room was simply well ventilated and the bottles refilled until they no longer gave off any liquid on a weekly basis.
The values have since improved significantly and leveled off at values of 70% relative humidity. The value on my test stone has gone down to 0.8. The whole thing has remained at these values for a few weeks now.
My visitors/guests who follow the project have confirmed a strong improvement. Since I’m in the basement practically every day, I don’t notice it myself as much as my sporadic guests.
I have since removed the false ceiling to the basement. In the article“Renovate basement ceiling – replace steel beams” you will find some details and of course the matching video.
Furthermore I installed a pump sump in the basement and also made a video for my playlist Playlist for the drainage recorded.
So I am confident that the drainage will also work in this basement.
Summary and conclusion
I continued the drainage of our over 100-year-old cellar in the town villa by installing an effective waterproof horizontal barrier using the injection method.
This technique was crucial in eliminating the persistent damp in the walls.
The eastern part of the cellar had already been successfully drained and I started to treat the western part.
The draining was successful overall and made it possible to use the cellar as a workshop later on without moisture damaging tools or materials.
I also experimented with infrared heating, but this did not make a significant contribution to draining the floor.
The infrared heating that I used in the basement drying process worked by emitting infrared radiation, which heated the wall surfaces directly.
This technology differs from conventional heating systems, which primarily heat the air and distribute heat via convection.
Infrared heaters heat objects and surfaces directly by radiation, which can be a direct and often more efficient source of heat.
In the specific context of basement dehumidification, the use of infrared heating was aimed at accelerating the evaporation of moisture by directly heating the damp walls.
The heat from the infrared rays penetrates the surface of the wall, increases the temperature locally and thus promotes the evaporation of water from the masonry.
Despite these theoretical advantages, infrared heating turned out to be less effective in practice.
The main reason for this was the inadequate performance of the heating system in terms of the energy required to heat the massive, damp basement walls sufficiently.
The infrared heating could not heat the walls to the extent that significant evaporation of moisture was achieved.
This was especially problematic in a large, poorly insulated space like my basement, where heat loss is high and moisture control challenges are greater.
In addition, the energy consumption of infrared heating, although lower than that of conventional fan heaters, was still considerable, which called the cost-benefit ratio into question.
Infrared heating therefore proved to be a costly option that ultimately did not produce the desired results in draining the cellar.
The combination of targeted injections and regular ventilation ultimately proved to be the more effective strategy for permanently solving the moisture problems in the basement.
