The Werstahl Hercules HS is an automatic multi-fuel solid fuel boiler. It burns olive pits, kernels, pellets, coal and bark, and with the cast-iron grate it burns wood too. With the matching burner it also runs on oil, LPG or natural gas.
The fuel is stored in a 320-litre silo and reaches the burner through a steel auger driven by a geared motor. A fan with adjustable speed supplies the combustion air.
The burner has a flashback protection system, electronic and mechanical, and a fire extinguishing system. It comes with an analogue control panel.
What every Hercules HS comes with, from the silo to the panel.
It holds about 205 kg of pellets and feeds the boiler automatically for days. Fewer refills and steady heat, even in the coldest spells.
The analogue panel shows the water temperature at a glance and sets the burner, the circulator and the feed. Simple and durable, no menus.
The flue gases pass through tubes surrounded by the boiler water. More heat exchange surface, lower flue gas temperature, less fuel. Its design also makes cleaning easier.
It brings the fuel from the silo to the burner at a steady, smooth rate. It resists wear and reduces jams.
With the matching burner the boiler also runs on oil, LPG or natural gas. A backup when the biomass runs out, or an alternative whenever you need one.
Three front doors: the heat exchanger, the burner and the ash drawer open separately, and the silo opens from the top.
With pellets and biomass the boiler runs automatically from the silo. With wood it runs manually, on the cast-iron grate. With a burner, on oil or gas as well.
The wood grate and the oil or gas burner are added separately.
All models share the same silo, 85% efficiency and a 200 mm flue. Choose the size by the space you heat and, ideally, a heat loss study.

2610 334 389 info@climaventis.grThe model comparison shows the heated space of each size, indicatively from 220 m² for the HS40 to 550 m² for the HS100. The right choice depends on the insulation and the climate, so a heat loss study is needed. Call us and we will help.
Yes, with the cast-iron wood grate, which you add when you order. With wood the boiler runs manually; with pellets, olive pits and other biomass it runs automatically from the silo.
The silo holds 320 litres, about 205 kg of pellets. According to the manufacturer, autonomy reaches up to 136 hours on the HS40 and up to 69 hours on the HS100. In practice it depends on the fuel and on how much heat the house needs.
An analogue panel, simple and durable: boiler water thermometer, burner and circulator thermostats, and an auger timer for the feed rate. It is included in the price.
Yes. The boiler has a port for an oil, LPG or natural gas burner. The burner is added separately.
A yearly service by a technician, replacing the anode rod and checking the safety systems. It is also a condition of the warranty.
7 years on the boiler and 2 years on the electrical and electronic parts, throughout Greece, provided it is serviced every year.
The boiler ships by carrier throughout Greece, with the cost shown in the cart, or you collect it from our shop in Patras. A heating installer fits it; we can suggest a partner in your area.
With a Mastersol hot water cylinder, your hot water is heated by the boiler while the heating runs. The triple-energy ones connect to a solar system as well.
