Information about the manufacturer Vaillant

The most well-known heating brand in Europe, Vaillant, recently commemorated its 145th anniversary. The company is well-known worldwide for its products. Today, the company employs 12,000 people across 14 businesses in eight countries. Vaillant is interested in alternative energy sources in addition to heating systems.

Officially, the Vaillant brand began in 1874 as a pump workshop. Then the industry saw a technological revolution with the introduction of the Johann Vaillant, an enclosed gas water heater. Vaillant started producing wall-mounted water heaters for homes in 1905.

Over the years, the company has not only updated its creations with the newest production technologies, but it has also looked for substitute technologies to meet the utility needs of homes. Vaillant introduces sophisticated models featuring a zeolite-gas heat pump in 2010. Zeolite’s inherent heating qualities can now be used by households for water heating. The heat pump uses secondary energy and lowers CO2 emissions, making it a novel technology for energy and heating equipment.

The first ecoPOWER 1 home water heater was introduced in 2011.0 with the production of heat and electricity. The pre-programmed, intelligent universal system is incredibly effective and eco-friendly.

The company introduced a 3 kW hybrid heat pump model in August 2012 that is paired with a boiler to provide optimal energy efficiency when operating.

More details! The company’s first Green iQ labeled products are ecoTEC exclusive, flexoTHERM exclusive, and flexoCOMPACT exclusive. Vaillant launched this line of high-quality, eco-friendly, and efficient products in 2015.

Design of Vaillant gas boilers

The heat load is a heater’s most crucial parameter. It varies from 10.0 to 30.0 kW at Vaillant. This size determines the water heating rate in liters per minute. When choosing a model, consideration is given to the weight, dimensions, and chimney cross-section size—all of which are crucial factors. These days, Valiant gas columns come with automatic start-up control via an electronic device and semi-automatic ignition via piezo ignition.

The user initiates piezo ignition by pressing the start button, which causes a spark to appear and ignite the wick, which in turn ignites the gas in the burner device. The wick burns continuously while the device is operating, which causes the gas to be consumed excessively. Therefore, electronic ignition, in which the spark appears automatically, is a more effective and ideal starting system.

The source of sparking could be regular batteries or the main electricity supply, depending on which mode the user chose when the boiler started up. An integrated generator that is powered by the incoming water’s movement provides the electronic ignition’s power supply in GRX type units with water flow rates higher than 2.2 l/min.

A draught overturning sensor, fitted to flow devices of the RXI and GRX types, senses the discharge in the column and, should it equal "0," automatically cuts off the gas supply to prevent flue gases from entering the room. The RXI type of vacuum column is designed to prevent overheating in the heat exchanger by shutting off the gas supply when the allowable limits are surpassed. The burner is a chrome-nickel steel device used for gas combustion. Two knobs on the front panel operate as the column’s control unit.

Crucial! The GRX and RXI units come with a copper heat exchanger coated with SUPRAL anti-corrosion coating and a gas pressure regulator that enables the device to operate steadily at gas parameters between 13 and 20 mbar.

Operating principle

Utilizing a vaillant gas flow water heater is simple. The draught in units featuring an open combustion chamber arises organically and is contingent upon the chimney’s height.

1. When the hot water tap is opened, it passes through the gas valve reducer with integrated diaphragm.
2. Due to the increase in pressure in the water pipe, the rubber diaphragm bends and acts on the plate, pushing out the water rod, which presses with a pressure of about 50 kg on the gas valve, opening it, after which the gas supply to the combustion area begins.
3. At the same time the rod presses on the plate, as a result of which the batteries are switched on, providing a spark for ignition.
4. After ignition of the flame, the flame sensor sends a signal to the module, which switches off the spark plug.
5. After closing the hot water tap, the pressure in the water supply network decreases, the gas valve cuts off the gas supply to the devices and the heating process stops.
6. The ionization sensor, when no flame is detected for 6-7 seconds, sends a signal to the control board, which shuts off the gas supply. This protection system does not allow the accumulation of carbon monoxide and its entry into the room.
7. The temperature sensor is responsible for the degree of water heating, if the limit values of heated water are exceeded, the electronic control board also cuts off the gas supply.

Kindly take note! The regular flow of flue gases, their release into the atmosphere, and the avoidance of gas explosions within the room are all under the control of the draught sensor. The sensor sends a signal to the control unit, which turns off the gas supply, when it falls to"0," which might happen, for example, when the gas duct becomes blocked with soot.

Popular models

Vailant AtmoMAG exclusiv RXI gas heater with automatic battery-operated ignition and modulating burner. The burner device’s potential heat output ranges from 30.0 to 100.0%. The process is automated, and the rate of burning is set in response to variations in the heated medium’s pressure.

The semi-automatic column with piezo ignition, draught sensor, and overheating protection AtmoMAG exclusiv RXZ is another well-liked model. It features an electronic flame control sensor and an integrated modulating burner. This universal modification offers stable operation at low gas parameters and is compatible with two fuel types.

Instructions for connection and operation

Kindly take note! As mandated by the warranty terms, it is advised that a qualified Vaillant service perform the installation and initial start-up.

Guidelines for turning on and maintaining Vaillant gas boilers:

1. Before turning on the Vaillant gas heater open the gas and water taps.
2. Ignite the igniter, for this purpose press the load regulator and turn from the position "Off" to "Ignition", at the same time press the piezoelectric ignition button.
3. Check the presence of the flame through the viewing window.
4. Release the piezo ignition button and keep the power regulator pressed down for a while longer
   about 10 sec.
5. If the device is not ignited, hold the regulator knob for up to 60 seconds to ventilate the gas duct and repeat the start-up with piezoelectric ignition.
6. After creating a stable burning flame turn the power regulator from "Ignition" to "On" position. In this mode, when the hot water tap is opened, the heater will automatically switch on and when it is closed, it will automatically switch off.
7. The water temperature is set by the thermostat on the unit"s panel. To increase it turn the knob to the right and to decrease it turn it to the left.
8. To turn off the heater, turn the power regulator from the "On" position to the "Off" position while it is pressed down.
9. Close the shut-off valves on the gas and water lines.

Possible faults and remedies

Since vapourant gas water heaters operate in harsh and hot environments, they will eventually malfunction; this also applies to other models of a similar nature. The reduction of such appliances’ service life is influenced by the quality of the raw water and the breaking of factory operating regulations.

Principal flaws in Vaillant models

1. Wick does not light – thermocouple or gas valve is not working, they will need to be replaced.
2. Unit overheats and makes noise – heat exchanger clogged with limescale. In this model it is not repaired but replaced with a new one.
3. Water under the heater – leaks from the heat exchanger.
4. Igniter spark does not turn on – the flame controller will need to be replaced or the igniter spark will need to be repaired.
5. The appliance smokes, gases penetrate into the room – the gas duct or heat exchanger on the gas side is clogged, cleaning from soot is recommended.
6. Failure of the water unit due to stretching or contamination of the rubber diaphragm pushing out the gas valve stem. It is recommended that it be replaced with a silicone diaphragm that is more resistant to constant stretching.
