  • The planning phase before installation may need some critical thinking

5.   AB Loop Radiant Heat Manifold

This system features an all-in-one radiant floor boiling system. It provides automatic air ventilation, a temperature gauge, a shut-off valve, and more.

it is built with high-quality materials like stainless steel, which provide standard corrosion and pressure resistance and faster heating capacities.

Each manifold includes an automatic air vent, temperature gauge, drain valves with outlet caps, shut-off valve, and flow-balancing valve/manual, and it also comes with wheels. The wheels help with supplying and returning the trunks.

The system comes in various sizes to fit different kinds of spaces for dimensions. It measures 15.6 x 15.2 x 4.2 inches and weighs 13.22 pounds.


  • Comes with sub-floor thermal insulation
  • You can install it without cement
  • Has anti-microbial resistance
  • Has laminate floor noise reduction


  • You may need an expert to assemble it

How does an electric boiler work?

Like other boilers, the electric boiler’s operation principle is relatively simple. The device will heat water which will circulate in the heating circuit. It is this circuit that will then supply the heating network.

Unlike other models, the energy used by this type of boiler is electricity. It will, therefore, not use fuel such as wood, fuel oil, or gas. Thus, the user will not have to install a smoke evacuation duct.

However, the means of heating all-electric boilers are not the same. Therefore, we can find three categories of electric boilers on the market: classic, ionic, and induction.

Classic electric boiler

This is the most common type of boiler. It is equipped with a resistance whose main role is to heat the water in the heating circuit. The boiler also has a tank containing hot and cold water. When the hot water pressure is sufficient, it will be released through a valve. So when the hot water drains, another valve will bring cold water to the hot water tank. It is possible to regulate the heating thanks to the probes.

Ionic electric boiler

To provide heat, this type of boiler uses an ionizer. It is also called an ionization boiler because the heating body of the device is an ionizer.

To put it simply, ionization is the act of adding or removing one or more electrons from molecules.

This will produce energy that will be used in the form of heat and will then be sent to the coolant. Afterward, it is the exchanger which will ensure the transmission of heat to the water in the circuit.

Electric induction boiler

The technology used is similar to that of induction hobs. The principle is, therefore, quite simple. In contact with metal, an electromagnet will produce heat. Then the heat will be transported to a heat transfer liquid. The heat will be transmitted to the heating water through the plate heat exchanger.


An electric boiler can be installed without major difficulties compared to other alternative systems.


First, it is essential to determine a suitable space to accommodate the equipment. A dry, clean, and accessible place will allow the boiler to be installed without hindrance. This will also facilitate any handling in the event of a breakdown.

If the system must be fixed against a wall, some checks on the solidity and condition of the partition are essential. Although some models of electric boilers are really compact, the weight of such equipment requires total security during installation.


The second step concerns the connection of the water inlet and outlet pipes. All the experts recommend installing an additional tap to facilitate electric boiler maintenance. The presence of a valve is essential to avoid specific complex scenarios. This must be connected to the drain hose (oriented vertically).


The last installation phase concerns the electrical connection. The cabling used must follow the standards imposed in France. The presence of a circuit breaker and earthing are also essential.


Floor heating systems are as essential as air cooling systems; they help to balance things up as too much of the other can become trouble. Radiant floor heating systems provide a durable and efficient all-around solution. They are versatile and mostly easy to install and maintain. These five picks are excellent for anyone looking to make an excellent and durable choice regardless of the shape and size of their living or office space.
