Gas heating with solar storage for households

Solar storage for households with gas heating: 200-litre vs. 300-litre options

Many households with gas heating face a common problem: During the winter months, gas heating is indispensable for providing comfortable warmth throughout the house. But in the summer, when hot water demand is low, these large heating systems often work inefficiently. The high operating costs of gas heating are particularly noticeable then, as it is often only used for minimal requirements. An ideal solution here is the combination of photovoltaic modules with a solar storage tank, such as the one offered by fothermo.

Photovoltaics and solar storage: A modern solution

Instead of feeding photovoltaic power into the grid, photovoltaic modules can be connected directly to the fothermo solar storage unit. This converts the generated electricity (direct current) directly into thermal energy and stores it for hot water production. This enables efficient use of solar energy to reduce the gas heating load, especially in the summer months.

The 200-litre solar storage tank: Who is it suitable for?

A 200-litre solar storage tank from fothermo is particularly suitable for smaller households or those with a moderate hot water requirement. Here are some considerations:

1. Household size: For one- to two-person households, a 200-liter storage tank is often sufficient. Since the hot water requirement is low, the photovoltaic system can fill the storage tank efficiently without resorting to fossil energy sources.
2. Space requirements: A more compact storage unit takes up less space and is therefore ideal for households with limited space.
3. Efficiency: Smaller storage units can be fully charged more quickly, which increases the overall efficiency of the photovoltaic system and further reduces gas consumption.

The 300-litre solar storage tank: The advantages for larger households

For larger households or those with higher hot water requirements, a 300-litre solar storage tank from fothermo offers decisive advantages:

1. Household size: Three to four-person households benefit from the larger capacity of a 300-litre storage tank. It can easily cover the hot water needs of multiple users.
2. Optimization of solar yield: The larger storage can absorb and store more of the solar energy, which further reduces dependence on gas heating.
3. Future-proof: A 300-litre storage tank provides enough reserves for a growing family or frequent guests, ensuring that there is always enough hot water available.

Why the combination of gas heating and fothermo solar storage makes sense

The inefficient use of a gas heating system in summer can be significantly improved by integrating a fothermo solar storage system. By using the solar energy that is fed into the storage system via the photovoltaic system, the load on the gas heating system can be largely reduced in summer. This significantly reduces operating costs and leads to a more sustainable energy supply.

Installation by a professional: quick and uncomplicated

The installation of a fothermo solar storage tank should ideally be carried out by a heating engineer. The installation process is similar to that of any other storage tank and can therefore be carried out quickly and without much effort. The specialist ensures that the storage tank is optimally connected to the existing gas heating system in order to guarantee the greatest possible efficiency.

Conclusion: 200 or 300 liters?

Whether you choose a 200-liter or 300-liter solar storage tank, the decision depends on the specific requirements of your household. A 200-liter storage tank is particularly suitable for smaller households, while a 300-liter storage tank is ideal for larger families and higher hot water requirements. By opting for a fothermo solar storage tank in combination with your existing gas heating system, you are investing in a future-proof, cost-saving and environmentally friendly solution that will convince you in the long term.
