HERMES - boilers with automatics (25 kW)

Information

HERMES central heating boilers are modern heating appliances equipped with automatic fuel feeding system and air dosing system for combustion. The whole facility is complemented with the fuel tank and temperature control device. Thanks to the application of modern retort burner with wide operating range (25 - 100%), the most economic constant system combustion has been obtained.

The fuel transport from the tank to the retort burner is carried out by means of the feeding screw. The heat exchanger is made of a high class boiler steel which guarantees long durability.

The advantage of HERMES central heating boilers is a small hearth, so called retort hearth of a high efficiency. The characteristic feature of HERMES central heating boilers is low emission of harmful compounds, achieved due to smoke-free fuel combustion.

Additional recovery of heat contained in fumes is obtained thanks to the special construction of pipe heat exchanger which guarantees high efficiency of the appliance.

In comparison to standard coal combustion processes, the technology which uses retort burners significantly reduces fuel consumption and restricts nitric monoxide and carbon dioxide emission. In consequence, less energy is used and costs are reduced. In comparison with central heating boilers fired for example with heating oil, the savings throughout the year may reach the 1:3 rate in favor of solid fuels.

Combusted fuel from the burner:

pea-coal

fine coal

pea-coal
/ pellet

pea-coal
/ oat

Grilled fuel burned:

Control

Device task is an automatic blown-in steering in the central heating boiler and switching on the pumps: circulation, domestic hot water and floor pump in a central heating system. Adjuster cooperates with the boiler screw feeder.

Steering process is carried out through the water temperature control in the central heating boiler.

Adjuster has two modes:

  • Operation mode (when the central heating temperature is lower than set-point)
  • Maintain mode (when the central heating temperature is equal or higher than set-point)

Adjuster enables to maintain the set temperature of domestic hot water as well as keeps the inside temperature of building. Adjuster requires settings change due to fuel diversity and boiler type.

Boiler configurations

In the advanced boiler configuration we offer a few options:

  • we offer a selection of the location of the feeder from the left-hand / right-hand side of the boiler
  • we offer a selection of opening the door to the left / to the right
  • we offer a selection of the diameter and kind of power and return connectors
  • we offer a selection of the location of the power and return connectors
  • we offer a selection of the shape and location of the boiler flue, e.g. elbow to the left, to the top etc.

1. The output of the flue
from the back
shifted to the left.

2. The output of the flue
from the back
in the middle.

3. The output of the flue
