Perfect combination: fothermo solar storage tank and pellet heating system
Efficiency through clever system integration
The combination of a fothermo solar storage tank and a pellet boiler offers a sustainable and, above all, efficient solution for year-round hot water supply. While the pellet boiler provides space heating and hot water in winter, the solar storage tank takes over this task during the summer months. Incidentally, using a wood-fired boiler is also possible. The design and operating principle of a wood-fired boiler in combination with a solar storage tank are essentially identical.
Functional description of the fothermo solar storage tank
The fothermo solar storage tank directly converts solar power from photovoltaic modules into thermal energy. Hot water is heated via electric heating elements that directly utilize the direct current from the photovoltaic modules. This energy conversion process achieves an efficiency of over 99% and operates without the need for inverters or batteries. The water is heated to up to 65°C using the photovoltaic power. Since no moving parts are required, the solar storage tank is a completely maintenance-free solution for hot water production.
Advantage: Pellet heating can be switched off in summer
A key advantage of this combination is that the pellet heating system doesn't need to be operated from April to October. Constantly heating and cooling a pellet heating system is inefficient, labor-intensive, leads to unnecessary wear and tear, and increases maintenance costs.
Cost-efficient, sustainable and resource-saving
Using a fothermo solar storage tank (available in 200-liter or 300-liter versions) significantly reduces pellet consumption. This not only saves on heating costs but also reduces CO₂ emissions. Furthermore, it extends the lifespan of the pellet heating system, as it is protected during the summer months.
economy
The fothermo solar storage tank is typically operated with six photovoltaic modules. This converts approximately 2,400 kWh of solar power into hot water annually. Taking into account the losses avoided by switching off the pellet heating system, this results in total energy savings of approximately 3,000 to 4,000 kWh per year. Assuming that 1 kg of pellets provides an average of 5 kWh of energy, this equates to a saving of approximately 800 kg of pellets per year.
Flexible retrofitting and easy installation
The fothermo solar storage tank is easy to install and can be used
Easily integrated into existing heating systems. The pellet boiler is connected to the heat exchanger integrated into the solar storage tank. This is done in the same way as with any other heat storage tank. A temperature sensor from the pellet boiler can be inserted into one of three temperature sensor tubes integrated into the solar storage tank. Depending on the model and design, the pellet boiler can then heat the water to the required temperature during the winter months. This makes the solar storage tank an ideal solution for new builds and renovations.
Advantages of the solar storage system
Installation is very simple. The photovoltaic modules are screwed directly onto the storage tank. The direct current from the photovoltaic modules is used directly. Since the entire system operates at a very low voltage (extra-low voltage), no electrician is required for commissioning. Registration of the photovoltaic modules is also unnecessary, as no electricity is fed into the public grid. Furthermore, the entire system requires no modifications to the house's electrical system or any work on the electrical panel.

Conclusion:
The combination of the fothermo solar storage tank and pellet heating system is an intelligent, future-proof, and cost-effective solution for efficiently and sustainably generating hot water all year round. It lowers operating costs, reduces emissions, extends the lifespan of the heating system, and contributes to environmental friendliness – a true winning formula.
