Old houses are gradually being renovated and converted to a new type of communications and heating appliances - bimetallic radiators with bottom connection. In the private sector, this is an alternative to obsolete cast-iron batteries - lightweight, aesthetic, and long-lasting. The bottom eyeliner will help hide the pipes to the floor. Before buying, experts recommend figuring out what is special about bimetal models.

The main types of heating appliances
At the moment, various types of heating appliances are being produced, and each has its own price range, advantages and disadvantages. Bottom eyeliner is only available on different batteries, if only they have inputs:
- Sectional bimetal heating radiators with convection plates, connection to pipes is possible from any of 4 points, this is their versatility. Heat losses are minimal, efficiency is high - by adjusting the thermostat, they regulate power.
- Panel (there are smooth and grooved) heating devices are available for lower connection, most often they use a saddle. All components, including regulators of thermal power, can be additionally picked up at the store.
- Steel models of a tubular shape are considered relatively new, their functional efficiency is proven - maximum thermal return. Designed for all types of eyeliner, but the presence of the necessary inputs must be checked upon purchase.
- Reminiscent plates, bimetal radiators with bottom connection are structurally similar to aluminum counterparts. But these are durable, well tolerate water hammer in urban schemes, which happen before the start of the coolant. With a lower connection, the heating efficiency is slightly reduced, but their aesthetics and convenience compensate for all the shortcomings.
- Aluminum models at the lower connection are less common, but they are willingly used in an autonomous system of country houses to minimize rust clogging.
- Designer radiators are available in various sizes and shapes, from ferrous metal and composite materials, bimetal heating radiators and cast iron finned batteries in a retro style. In terms of thermal power, they are in no way inferior to copper and steel models. Most often they are mounted with a bottom connection to hide the pipes and not spoil the interior design.
Bimetal radiator fits perfectly into any interior
Note! With illiterate installation of a hidden eyeliner, leaks occur. You will have to disassemble the floor covering to fix the problems, and this is an additional repair cost. Entrust installation to specialists if there is no experience.
When replacing old radiators, it is recommended to replace pipes that may not cope with the increased load. Airing and clogging is the main problem of the cold in the house when the boiler is operating at full capacity. Rust, organic matter and calcium deposits accumulated in the system will continue to reduce their effectiveness, even to cold areas.
Effective use of bottom connection bimetal batteries
Resistant to water hammer, these batteries well tolerate pressure surges in the system. And if you need to block one apartment for several years, nothing will happen to them after a long shutdown when starting the coolant, as is the case with rusty pipes and black metal batteries.
In the private sector, the use of bimetallic radiators with lower eyeliner is not entirely justified, although they are actively crowding out other varieties. They can be increasingly seen in offices and cafes, hotel complexes and office buildings. New apartment buildings operating on autonomous boiler houses are also often transferred to the lower connection of bimetallic radiators.
Operation of bimetallic radiators in public catering facilities
In private houses, priority is not given to special parameters of endurance, but to aesthetics and a hidden pipeline with a coolant. In a closed circuit, antifreeze or “non-freezing” with different chemical compositions is also applicable. Bimetallic models of domestic and foreign production will cope with adaptation to a new type of coolant. The range of bimetallic radiators is not very different in design variety due to the specific structure. But there is a large selection in format - the height and length of the batteries varies over a wide range.
Attention! The lack of variability is due to the inability to build radiators with bottom bimetal inlet. It is necessary to select heating devices according to thermal power according to the room.
Bimetal radiator in a sleek design
Connection inputs are comparable to modern pipes, but for older communications there are suitable fittings if the system does not require repair. Do-it-yourself pipes are connected through the lower connection block or directly. Recall that bimetallic batteries with a lower circuit are usually used in single-storey private houses. It is only important to ensure a sufficient distance (7-12 cm) from the heating block to the window sill and floor to ensure sufficient circulation of air masses.
The specific structure of bimetallic batteries
The advantages of the bimetallic tandem determine the mode of production. Alloy steel inner pipes (some foreign manufacturers even have copper) provide protection against pressure surges in the heating system. They are less susceptible to corrosion than other options, so they are less clogged and airy. The design of the body of bimetallic radiators provides light metal with high heat transfer, and here aluminum has no equal. The built-in thermostats quickly adjust to temperature control. The reduced heat transfer (due to the bottom connection) is partially compensated by the convection heating method and stable temperature support.
Most often, radiators are placed in window sills.
In heating systems with a lower radiator connection, steel, aluminum and bimetal models are used. Bimetal wins against both competitors. In fact, this is the steel base inside the aluminum plates coated with an aesthetic layer of plastic or heat-resistant paint. These heaters have the highest heat transfer, comparable only to cast iron, but they have an advantage in weight and cost. Their popularity is determined by growing demand. It may seem that, relative to another product in the market of thermal equipment, the cost of radiators made of steel and aluminum is the highest. However, their aesthetics and technical characteristics are not in doubt, which is why these models are in steady demand.
Important! For the lower eyeliner, the correct choice of the installation location of bimetallic radiators plays an important role. Most often, batteries have one place - a window sill, but there may be options if the windows in a private house are narrow and there are many.In this case, select the opposite points of the room so that the room warms up evenly.
Experts recommend choosing radiators with round-shaped plates, especially when the family has small children. All additional equipment is available in any specialized store (department of a supermarket) where thermal equipment is sold. The consultants will tell you which valves, Mayevsky taps, adapters, relays or thermostats will be needed for the purchased batteries.
