The Werstahl BioHydro Pellet is a Greek-made water-heating fireplace that burns pellets, olive pits, wood and coal. It connects to the radiators of the house and works like a boiler, on a closed or an open circuit.
Pellets and olive pits are fed automatically from a 200 kg silo, which can stand to the right, to the left or behind the fireplace. With wood or coal it runs manually, like any fireplace: you load the fuel into the hearth by hand.
It is built from 5 mm ST37-2 steel, with a 6 bar test pressure and a 3 bar working pressure, and holds 80 or 120 litres of water. It has mechanical adjustment of the primary combustion, secondary combustion for higher efficiency and lower emissions, and tertiary combustion so that the ceramic glass does not blacken often. The door slides up on gears and a chain, and also opens to the right or to the left.
What every BioHydro Pellet comes with.
The silo holds 200 kg and feeds pellets or olive pits to the hearth automatically. It can stand to the right, to the left or behind the fireplace, whichever suits your room.
The geared motor under the silo brings the fuel to the hearth. As an indication, a full silo gives up to 90 hours of autonomy on the BioHydro 30 and up to 80 hours on the BioHydro 40.
Pellets and olive pits arrive automatically at the base of the hearth. When you want wood, you load it by hand, like in any fireplace.
The door slides up on gears and a chain, and also opens to the right or to the left. Tertiary combustion, an air curtain, sends hot air across the door: combustion is more efficient and the ceramic glass does not blacken often.
On the BioHydro both dampers are added when you order; their price is added to the price of the fireplace.
Lets you adjust the flow of the flue gases and the intensity of the fire by hand.
Lets you set how much air enters the combustion chamber, for better control of the flame and the temperature.
With pellets, olive pits and other biomass the fireplace runs automatically from the silo. With wood or coal it runs manually, like any fireplace.
Both models have a 200 kg silo, 5 mm steel, a 6 bar test pressure and the same features. Choose the size by the heat output of the radiators in your home.

Yes. It connects to the radiators and works like a boiler. The comparison shows the indicative heated space of each size; it depends on the climate and the heat losses of the house.
According to Werstahl, a fireplace is chosen not by floor area but by the heat output of the radiators plus 20-30%. For radiators of 20,000 kcal: 20,000 × 1.30 = 26,000 kcal, about 30 kW. Call us and our engineers will help.
To the right, to the left or behind the fireplace. It holds 200 kg; as an indication, autonomy reaches up to 90 hours on the BioHydro 30 and up to 80 hours on the BioHydro 40. In practice it depends on the fuel and on how much heat the house needs.
The BioHydro connects to either. There are connection kits for an open circuit, for a closed circuit and with a heat exchanger, supplied with a detailed connection diagram. The choice depends on the installation; we will help you choose.
The chimney damper adjusts the flow of the flue gases and the intensity of the fire by hand. The air intake damper sets how much air enters the combustion chamber. On the BioHydro both are added when you order.
7 years on the whole fireplace and 2 years on the electrical and electronic parts. Ask us about the warranty terms.
The fireplace ships by carrier throughout Greece, with the cost shown in the cart, or you collect it from our shop in Patras. An installer fits it; we can suggest a partner in your area.
The main parts for an open circuit, a closed circuit or a connection with a heat exchanger, and the pre-assembled kit, which fits every Werstahl water-heating fireplace. Ask us which one suits your installation.
