The name of this type of heater comes from the similarity of the place of its installation with the location of the plinth — an element of the decoration of the room, mounted around the perimeter of the junction of the floor with the walls. Baseboard heaters are devices patented at the beginning of the last century, but the improvement of their design in accordance with modern requirements has begun recently, which has led to an increase in the popularity of warm baseboards, due to many advantages.
In order to better navigate the existing types of heaters when choosing a method of heating housing, we will consider this device in more detail.
A baseboard heating device is a system for heating a home, installed above the junction of the floor with the walls at a low height. In addition to the way the heater is located in the room, it may also have an external resemblance to a conventional skirting board, since the external design of skirting heaters is different.
But, even if the artistic solution for the design of the device is far from what a real plinth looks like, it is quite an appropriate solution to hide floor-to-wall interface defects with it.
The plinth heater is a lengthy heater of small cross-section — an infrared heat emitter placed in a decorative protective casing. The system is attached to the walls with brackets and is located at the floor level or slightly higher, being the main or additional means of heating the home — depending on the height of the room, the length of the device and its power.
The plinth heater heats the room due to two factors — the infrared radiation of the heat exchanger and the convective movement of the air heated by the device, which creates a screen, a screen between the walls and the main space of the room. This warm screen, unlike the heat of convector radiators, heats the walls around the entire perimeter of the room, and they also begin to radiate heat towards the center of the room.
Varieties of baseboard heaters
Skirting heaters are classified according to the method of heating and are divided into the following types:
In water units through the heating system, transferring heat to the surrounding air, the coolant circulates — hot water, in pure form or with additives against freezing (at objects with periodic residence of residents).
In electrical devices the heating of the heat exchanger is carried out by heating elements (thermal electric heaters), which convert electric current into thermal energy when it passes through a spiral of a material with high resistivity.
Plinth type heaters
Both types of warm skirting boards transfer heat to the surrounding air through heat exchangers — two of their copper pipes, to which, due to the small area of u200bu200btheir side surface, transverse ribs with a small spacing are added. In copper pipes, depending on the type of warm plinth, heating elements are placed or hot water circulates. Outside, the design of the heater is placed in a metal case with a system of slots for natural air circulation.
Section and schematic arrangement of water and electric warm skirting boards
The baseboard water heater transfers the heat received with hot water from the central heating system or an autonomous boiler. Water that has cooled down after heat transfer when passing through a warm plinth is returned to the central or autonomous heating circuit for heating. Thus, a warm water plinth is an additional consumer of heat carrier energy.
If the unit is electric, then in its lower copper tube there is a system of heating elements, connected in parallel with each other by a heat-resistant silicone cable, brought out together with a ground wire through the upper tube.
Depending on the length, heating elements are produced with the following power:
- 0.7 m — 140 W;
- 1.0 m — 200 W;
- 1.5 m — 300 W;
- 2.5 m — 500 W.
The advantage of an electric warm skirting board over a water one is that it is equipped with a thermostat that provides economical heating in a manually set mode.
Models of skirting electric heaters are also produced using in the design instead of heating elements a high-temperature heating cable, the operating surface temperature of which reaches 240 degrees. Celsius.
Installation and operation rules
Depending on the quality in which the system of warm skirting boards will be used — the main or additional means of heating, it is mounted around the perimeter of the room or in separate sections. Design of skirting heaters — individual modules, including corner ones, allow you to assemble and install a warm skirting board of the required length, depending on the heating status, the power of the modules, the dimensions of the room and the degree of external thermal insulation of the building.
Installation of an electric baseboard heater
The installation of an electric warm baseboard begins with marking the walls.
Important! The heating system is located at least 1 cm above the floor surface, but not more than 20 cm from the level of the floor covering.
A self-adhesive heat-insulating tape is attached to the wall along the perimeter of the room or on areas separately selected for installing a warm plinth to reduce heat loss.
On it, 1 cm above the floor surface, using a bubble level, a horizontal line is applied — the lower boundary of the location of the heater. Then a plate is applied to it — the back wall of a warm plinth and the places for drilling holes for attaching the plates are marked.
Holes are drilled in the wall according to the marking and plastic hollows are inserted there, after which the plates are fixed with screws, assembling into a strip of the required length.
Brackets are attached to the mounted plates — holders for installing pipes, after which, using fluoroplastic inserts, pipes with heating elements are installed in them, assembling the modules into a single circuit.
For the baseboard heating system to work, it is necessary to arrange a separate electricity line to which it will be connected. Since the power of the heating elements built into the electric plinth varies from 140 to 500 W, you should not load the connection line with more than 15 modules.
The heating system of a warm baseboard also includes thermostat — an electronic or electromechanical device for maintaining the set temperature in the room (mounted in a warm plinth when using one module or installed separately when operating a system of several elements) with a built-in temperature sensor that monitors the temperature and sends data to the thermostat.
This element is installed after the installation of the skirting board is completed, choosing a place accessible to visual review, with an objective value of the air temperature in the room — not behind standing furniture.
The last operation is the installation of the front covers of the heaters — they are applied in place, put on top of the bracket and fixed with light pressure until they click. Then, holes are drilled in the linings at the locations of the bracket, and the front cover is fastened with a screw into the technological slot. The head of the screw is decorated with a decorative overlay.
Important! Front linings of warm skirting boards should have a shielded coating on the inside to reduce heat loss.
Installation of a warm water baseboard
Installing a baseboard water heater has a lot in common with installing an electrical device. The marking and installation of the rear panel is carried out according to the same technology — using a self-adhesive heat-insulating tape, after which pipe brackets are attached to the fixed plates.
Important! For efficient operation, the length of one contour of a warm water skirting board should not exceed 15 m.
The installed modules are assembled into one circuit using special threaded connections with rubber gaskets.
If the module needs to be shortened at the point of connection to the existing water heating system, then the design of the threaded connection provides for this operation — the element is cut to the desired size, then 2–3 ribs (lamellas) are removed from the tubes, and connecting nuts, flare cones and rubber gaskets.
When connecting a warm water plinth to the heating system, the nuts are baited manually, then tightened with keys, after which the module is installed in the groove of the bracket, and the threaded connection is finally clamped.
After the installation is completed, the tightness and operability of the system are checked — water is supplied, smoothly opening the valve to avoid water hammer. In places where leaks are detected, tighten the nuts or replace the gasket.
After eliminating the assembly defects, the front linings of the warm plinth are installed.
Important! Unauthorized connection of a baseboard water heater to the central heating system of an apartment building, which is not designed for additional heat carrier consumers, is prohibited.
Advantages and disadvantages
Like every heating system, a baseboard heater has positive and negative characteristics, both common to both types and inherent to each type individually.
General advantages of a warm skirting board
- Possibility of self-installation.
- Safety (absence of short-wave radiation, safe temperature of the outer casing, environmental friendliness).
- Functionality (heating, drying walls).
Disadvantages of a baseboard heater
Common disadvantages for water and electrical devices are:
- high cost of modules (depending on the quality of workmanship and the manufacturer, the cost of one running meter of a warm baseboard varies from 5 0 to 70$, which cannot be called a democratic price);
- the inability to use as the main heating in large areas;
- slowly achieving the effect of warming up the room.
In addition, the need to coordinate the connection of a water device to the central heating system calls into question the very fact of the possibility of its use.
An economical electric plinth heater can be called very conditionally, since the consumption of electricity for this method of heating medium-sized (20 square meters) and large areas increases significantly.
For those who want to purchase energy-saving heating devices for their home, skirting board units cannot become the main object of attention. But when choosing an alternative method of heating a home, a plinth-type heater, despite the rather high cost, can be used as a compromise option — for heating small rooms, especially children’s rooms, in the off-season, when the main devices are not yet involved, and daily temperature fluctuations are already significant. During such periods, this system, especially the electric version, is guaranteed to maintain a comfortable temperature in the room without significant costs.
