Merkury

Modern 2-hearth boiler

The MERKURY is a heating unit with the upper combustion of solid fuels and an extended flue gas circulation. The unit has two burning areas which permit automatic or manual replenishment of fuel. A special controller manages the operation of the unit to make burning even more efficient.

Superefficient and easy to use

The MERKURY boiler has a fixed grate to burn hard coal, wood and coke, in addition to a retort hearth which permits the burning of coal peas and wood pellets. This is a typical combination for 2-hearth boilers, the main advantage being the option to operate without electric power. The worm conveyor automatically transports the fuel from the hopper. The fuel has to be replenished as required. The fan blower supplies a continuous air flow to the burning zone in order to maintain a set temperature in the heated areas of the home.

Safe operation

The ST-480 control unit ensures the fully automatic and safe operation of the boiler. The MERKURY is fitted with protection devices and sensors which respond appropriately and guarantee the correct operation of the unit (e.g. a motor overheating sensor and a feeder temperature sensor). The auger operation monitoring system protects the boiler from damage resulting from a failure by stopping the fan, cutting out the air inflow, and by emitting an acoustic alarm signal.

Innovative fuel dryer system

The innovative system for drying fuel eliminates the possibility of vapour condensation in the hopper and reduces the risk of corrosion in the tank and feeder. In this way the service life of both the feeder system and the hopper is extended.

Long term warranty

The advantages of the 2-hearth MERKURY boiler are its high combustion efficiency and thermal efficiency (up to 86%). The temperature-resistant design, the top grade materials used for its manufacture and its modern operating system ensure long-term operation, which can be attested to by many of our Clients.

ST-480zPID control unit

The ST-480zPID controller is suitable for heating boilers fitted with a screw conveyor.
It controls 4 pumps for central heating, domestic hot water, floor heating and water circulation, as well as the fan and fuel feeder. The unit will also work with 2 mixing valves, a room controller, weather compensation unit, and a GSM module. The heat energy of the exhaust gas is not wasted by being released into the chimney, but it is used for heating.

Draught regulator

A draught regulator in solid-fuel boilers is a thermostatically operated device for controlling water temperature in the boiler.
A thermostat head of the regulator monitors the water temperature in the boiler and via levers and a chain actuates a throttle to increase or reduce the airflow into the hearth.

Room controller: ST-280, ST-292

The use of the room controller ensures easy control and readout of the temperature in the room, boiler, accumulation tank and mixing valves directly in the living space without having to go to the boiler room.
The room controller works only in conjunction with the main control unit which features RS communication from TECH. The large, clear, colour touch display ensures easy operation.
The ST-292 unit is designed to control a heating unit (e.g. a gas/oil/electric boiler or a boiler control unit). The controller is intended to maintain a set temperature indoors, transmitting the signal to the heating unit (open/close contacts) based on the actual room temperature.

GSM module

Don’t know what is happening to your heating boiler when you leave the house? The GSM module sends you texts about each alarm on the boiler controller.
Additionally, on sending a dedicated SMS message at any time (using an authorised number), the user gets text feedback on the current temperatures on all the sensors. When an authorisation code is entered, it is possible to change temperature setpoints remotely.

Internet module ST-505

The internet module is a device that allows the user to control the operation of the boiler via the Internet.
In this way, the user can monitor the state of all devices on the boiler system. It is also possible to view the temperature history, presented conveniently on clear graphs, as well as view the controller alarm history. Functionalities and the manner of configuration of the internet module depend on the type and software of the main control unit. With new controllers, the set-up process is made very easy (you can see “Registration” button in the submenu of the internet module – installation menu. The absence of this option means that the main controller is older type). The GSM ST-505 module also works with main control units of the older type.
