What is a warm wall in the bathroom, and how it can help save heat consumption: installation methods

It’s crucial to keep the bathroom warm and inviting, especially in the winter. An inventive way to improve comfort and cut down on heat usage is to install a heated wall.

With this system, heating components are installed inside or behind the wall to provide a uniform, soft warmth all over the surface. A warm wall can keep the bathroom at a comfortable temperature without significantly using additional heating sources because it distributes heat evenly.

Warm wall installation can be an economical way to reduce energy expenses and improve the comfort of using the bathroom. Selecting the ideal solution for your requirements can be made easier if you are aware of the various installation techniques.

Warm walls are a kind of surface heating in which radiant heat exchange accounts for 85% of the heat transfer from the surface. Although the temperature is about 2 degrees lower than with convective heating, such a process makes one feel comfortable. You can save money by keeping the room temperature between 18 and 20 degrees Celsius.

Advantages and disadvantages

The advantages and disadvantages of each heating system type must be taken into account before selecting one. Benefits of having a "warm wall"

• heating devices are hidden, which increases the area, aesthetics of the room and protects against burns;
• heat quickly spreads throughout the room, which saves resources;
• a warm wall is much more pleasant than a cold one, which is noticeable even without touching it;
• thanks to hidden elements, the air does not dry out, has uniform convection, eliminating dust accumulation;
• the system is used for heating in winter, and for air conditioning in summer;
• the coolant heats up no more than 40 ° C, which saves monthly resource consumption;
• types of warm floors are electric, water, infrared, differ in the coolant and heating elements.

Warm walls radiate heat into the room after heating the items within. As a result, a guaranteed effective heat reserve exists.

The following are some drawbacks of the "warm wall" system:

• heat should spread without obstacles, so there should be a minimum of furniture in the room;
• it is not recommended to drill the surface after installing the system;
• wall finishing quickly becomes unusable due to constant heating and requires restoration or complete replacement;
• heat is felt no further than 20 cm from the wall and creates the effect of a thermal cushion (rises upward), when ventilating, the temperature drops and additional resources must be spent on heating;
• when installing cables in an external wall, the dew point shifts and condensation forms both inside and outside the room, forming mold.

Remember the technological aspects. It is advised to mix various heating techniques to save costs and produce a comfortable microclimate.

Warm walls in bathrooms are a useful way to cut down on heat usage because they provide reliable, economical warmth where it’s most needed. By building a heating system right into the wall, this technique not only improves comfort but also lessens the need for additional heating appliances by helping to maintain a constant temperature. In order to help you increase the energy efficiency of your bathroom, this article will discuss the advantages of warm walls and provide easy installation instructions.

Material requirements

There are various recommendations that must be followed in order for the heating system to be implemented correctly. The following considerations should be kept in mind while selecting a system:

• the system consists entirely of pipes, so the price of the material affects the overall cost of the work;
• since the pipeline is under the plaster, it must be reliable and durable;
• the pipe must bend well, easy to install;
• during the leak test, the pipes must withstand pressure from 3 to 6 bar;
• use a high-quality plaster mix so that the surface is free of voids, withstands deformation and is resistant to vibrations.

How to install under tiles

As a heating system, the "warm wall" system works well in a humid room. Installation is done on exterior as well as interior walls.

Installing a water system is more challenging than an electric one. However, it is preferred under plaster.

"Dry method"

The first step in installing a system with a dry method is to choose prefabricated panels according to the wall’s overall area. Following that, you can complete installation in the order listed below:

1. Using foamed polyethylene on a foil base, insulate the inner part of the wall.
2. Attach the mounting tape or metal mesh with dowels.
3. Fix the heating element mechanically.
4. Cover the “warm wall” with a layer of plaster (rough) and leave until it hardens completely.
5. Perform finishing plastering, finishing puttying and decorative finishing.
6. After a month, you can turn on the heating and check its efficiency.

It is imperative to use special glue when laying ceramic tiles on a warm wall to prevent the finishing from crumbling over time. Plasterboard sheets can be installed over the cable if that’s what you want. You have to allow space ahead of time for screws to prevent errors.

“Wet method”

Make sure to use inside if it is not possible to insulate outside. Polyurethane foam or foam plastic are used for this. Panels with aluminum inserts are convenient to use; they are covered with plasterboard sheets following the circuit layout.

The pipes can be arranged either vertically or horizontally in a "snake" pattern. Because of how hard it is to remove the air lock, the "snail" method is not advised. To ensure that the temperature is set evenly throughout the space, it is best to use a variable step:

• up to 120 cm in height, pipes are mounted with a step of 8-15 cm;
• above 180 cm – 30-40 cm;
• in the range from 120 to 180 cm with a step of 20-25 cm;
• the circuit is laid under plaster or plasterboard;
• an electric pump is installed separately.

Verify that the circuit’s coolant flow is at least 0.25 m/sec. The water pressure needs to be high in order to force the air that has built up in the system out. Plastering the wall should be done after the pipe has been inspected for leaks.

What does the service life depend on

How well the guidelines are followed will determine how long the "warm wall" system lasts. It’s crucial to avoid later blocking the wall with furniture or ornamental panels.

It is important to consider heat transfer when carrying out the project to prevent the surface from overheating because materials that expand at high temperatures may develop surface cracks.

The system keeps the bathroom at a comfortable temperature and prevents the growth of mold and fungus because of the evenly distributed heat from the wall. In contrast to infrared heating, the air is not dried out or ionized.

When it comes to comfort and energy efficiency, a heated wall in the bathroom can make all the difference. It helps prevent the need for additional heating by keeping the temperature constant, which can result in appreciable energy bill savings.

A few essential materials and some simple assembly are all that are needed to install a warm wall. Depending on your needs and bathroom design, the installation procedure can be customized for either water-based or electric systems.

All things considered, installing a warm wall in your bathroom can increase comfort and be a wise decision for energy-conscious homeowners. This is an upgrade that can save money in the long run and provide comfort right away.
