With increasing concerns in rising heating costs many people are now investing in the benefits of biomass boilers, which are proving to be the perfect option to take advantage of the RHI scheme. To meet with this growing demand, Rural Energy are proud to announce their new range of Herz Single Phase Firematic boilers (130kW, 151kW, 180kW and 199kW) to add to their 80kW and 100kW versions.
Such is the popularity of this new range that contracts have already been won to supply and install 20 to Highland Council. For further details on these products or to discuss your biomass project please call Sophie de Ronde 0203 189 0654 or e-mail sophied@ruralenergy.co.uk
New boilers from Herz in the firematic range:
- Herz firematic 130: 37.8-130kW on wood chips, 42.7-143kW on wood pellets
- Herz firematic 151: 37.8-151kW on wood chips, 42.7-155kW on wood pellets
- Herz firematic 180: 42.2-180kW on wood chips, 54.8-183kW on wood pellets
- Herz firematic 199: 42.2-199kW on wood chips, 54.8-199kW on wood pellets
All have an efficiency of over 93%, have been tested at 3 bar and have a maximum working temperature of 95°C.
The firematic range of boilers at 80kW and above have a stepped grate fuel combustion chamber are suitable for burning either wood chips or wood pellets.
Central control unit as standard for:
- Burning control (Lambda probe control).
- Buffer management.
- Return flow temperature bypass (pump and mixer valve).
- 2 controlled heating circuits (pump and mixer valve)
- Domestic hot water preparation.
- Simple screen design and convenient menu guide.
- Option for internal modular extensions for solar circuit control as well as other heating circuits (total maximum 6 heating circuits, for solar-use maximum 5 circuits).
- The movement of the step grate is also a cleaning mechanism of the burning chamber. These grate elements consist of special, high-quality cast iron. Through the movement of the step- /moving grid the biomass is transported through the combustion area. The burning chamber is split into primary and secondary air zones. This is necessary to ensure a system which is adapted to the conditions of combustion.
- The movement guarantees optimal air flow through the cleaned grate.
- The cleaning of the combustion chamber from burning ash is carried by an automatically tipping grid. The screw below transports the ash directly into the ash bin.
- No manual effort required.
- Via the two ash discharge screws the combustion and fly ash is automatically transferred by auger into the ash bins.
- The removable ash bins with wheels enables simple and convenient emptying of the ash.
- Thanks to the in-built Lambda probe, which continuously monitors the flue gas values, the boiler reacts to changes in fuel quality ensuring optimum combustion and extremely low emission values.
- The Lambda probe controls the primary and secondary air supply ensuring complete combustion, even in partial load operation.
- The results are low fuel consumption and the lowest emission values even with different fuel qualities.
- The heat exchanger surfaces are automatically cleaned via the integrated turbulators, even during heating operation, eliminating manual cleaning.
- A consistently high level of efficiency thanks to cleaned heat exchanger surfaces enables low fuel consumption.
- Falling ash is taken into the ash bin via an auger.
They all have the same boiler bodies, measuring 1494mm in total length, 1888mm in width including the intermediate fuel hopper, for a room with a minimum height of 2400mm. The boilers weigh 1350kg and have a flue spigot 200mm in diameter.
