HERMES - akvoTANK - boilers with automatics (25 kW)

Information

HERMES - akvoTANK central heating boilers are water, steel boilers, solid fuel fired with moving, sequential retort burner, automatic fuel feeding system, hopper and microprocessor control device. HERMES akvoTANK central heating boilers are combination of the HERMES central heating boiler with akvoTANK VZW QP 150/1 hot water tank.

The heating boilers are fully automated, they do not need constant maintenance consisting of direct observation of combustion process; this role is taken over by controlling and regulating equipment.

Central heating boilers of this type are used in central heating and hot water installations, in residential buildings, public buildings, production buildings, and many others. HERMES akvoTANK central heating boilers are designed for solid fuels burning, i.e. hard coal of pea type, fines I and II, as well as biomass- based fuels.

Combusted fuel from the burner:

pea-coal

fine coal

pea-coal
/ pellet

pea-coal
/ oat

Grilled fuel burned:

coal

briquette

wood

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
from the back
shifted to the right.

4. The output of the flue
from the back
(the elbow to the left).

5. The output of the flue
