Introduction to the system

My name is Ivan Novak and I live in a small village in Croatia. A year ago I decided to replace the old boiler in my house with an 80 liter solar hybrid boiler from fothermo. This decision has changed my life for the better and I would like to share my experience with this system.

Use of solar energy

Since my house is located in a region rich in sunshine, I wanted to make the most of this natural resource. I installed two photovoltaic panels on the roof of my house, which are perfectly sufficient to supply the solar hybrid boiler with energy all year round. Especially in the summer months, the sun heats my water completely free of charge and in an environmentally friendly way.

Easy installation and handling

Installing the boiler was surprisingly straightforward. With the two photovoltaic modules, which I was able to connect effortlessly with a simple connection cable, the system was ready for use in no time. The boiler can be easily connected to the water network like any other electric boiler. The boiler started heating up very quickly after installation.

Reduced electricity consumption and environmental protection

Since installing the fothermo solar hybrid boiler, my electricity consumption has been reduced considerably. This not only has a positive effect on my electricity bill, but also gives me the good feeling that I am actively contributing to environmental protection. Using renewable energy for hot water was an important decision for me and one that I do not regret.

Conclusion: A worthwhile investment

The fothermo 80 litre solar hybrid boiler has proven to be the ideal solution for my needs. Not only is it efficient and environmentally friendly, but it is also easy to install and operate. I can highly recommend this system to anyone who lives in a sunny region and is looking for a sustainable hot water solution.

Our family, consisting of my wife, our three children and me, lives in a cozy single-family home. After our old drinking water tank rusted through and finally became unusable after around 20 years of faithful service, we were faced with the decision of finding a suitable and future-proof solution for hot water supply. After extensive research, we chose the 300 liter solar storage tank from fothermo - and that was one of the best decisions we have made in recent years.

Installation – Simple and Efficient

Replacing the defective storage tank with the new fothermo solar storage tank was straightforward. Thanks to the professional work of our heating engineer, dismantling the old storage tank and installing the new device only took one day. At a cost of 900 euros, the replacement was within budget both in terms of time and money. What surprised us in a particularly positive way was the fact that installing the new storage tank was just as simple as with a conventional storage tank - no special adjustments were necessary.

Photovoltaics – self-installed and ready for immediate use

As a handy do-it-yourselfer, I decided to take on the installation of the photovoltaic modules myself. I installed a total of six modules with a total output of 2580 Wp on the flat roof of our carport. The connection was child's play and after just a short time we were able to convert the first rays of sunshine into hot water.

Summer half-year – free hot water for the whole family

We are particularly impressed by the performance of the fothermo solar storage tank in the summer months. Our family of five is completely supplied with free hot water during this time. The gas boiler, which is normally responsible for heating water, can remain almost completely switched off in the summer months. This not only saves us energy costs, but also resources - a real plus for environmentally conscious people like us.

Winter half-year – Efficient support of the gas boiler

Even in winter, the solar storage tank reliably supplies hot water, albeit in smaller quantities than in summer. If it is not enough, our gas boiler automatically takes over the additional heating. The intelligent control by the temperature sensor of the gas boiler ensures that the water temperature in the storage tank always remains pleasantly warm. This interaction of solar energy and gas boiler gives us the security of never having to take a cold shower - a luxury that my wife and children particularly appreciate.

Maintenance-free – Another plus

Another major advantage of the fothermo system is that it is maintenance-free. Unlike conventional solar thermal systems, there are no mechanical components that could wear out, and the risk of frost or overheating damage is completely eliminated. The system is robust, reliable and easy to use - perfect for our needs.

Conclusion – satisfaction across the board

In summary, we can say that we are more than satisfied with our fothermo 300 liter solar storage tank. The simplicity and robustness of the system convinced us, and the possibility of enjoying a long, hot shower at any time with a clear conscience is something we are all particularly pleased about. We invested 4,400 euros in the entire system and installation - an investment that was definitely worth it for us. We can recommend the fothermo solar storage tank to anyone who is looking for a sustainable and uncomplicated solution for hot water preparation.

We are happy to have taken this step and look forward to many more years with our fothermo storage system.

We, the Reimann family, have lived in our cozy corner terraced house for many years. After our children moved out, we were faced with the decision to replace our old, inefficient electric boiler. The high electricity consumption of around 3,500 kWh per year for hot water production and electricity supply had increasingly bothered us. After thorough research, we came across the 80-liter solar hybrid boiler from fothermo - and this decision turned out to be an absolute stroke of luck.

Since we replaced the old electric boiler with the fothermo solar hybrid boiler, our electricity consumption has noticeably decreased. Instead of 3,500 kWh per year, we now only need around 2,300 kWh - a saving of around 1,200 kWh per year! This not only means less electricity consumption, but also a noticeable reduction in our household budget. At an electricity price of €0.30 per kWh, we save around €360 per year. Since we can use almost all of the solar power generated ourselves, the purchase of the boiler will pay for itself after around three years.

What is particularly impressive is that we can take hot showers completely free of charge from April to October. Thanks to the efficient use of solar power, the water stays pleasantly warm even when the sky is overcast. In the winter months, the automatic reheating takes over and ensures that we always have water that is at least 40 °C - even on the coldest days.

Installing the solar hybrid boiler was child's play. We connected a total of four photovoltaic modules with a total output of 1,280 Wp. With a simple 4-way parallel plug and two 10-meter extension cables, we were able to connect the modules to the boiler effortlessly. Connecting it to the water network was also straightforward, as the boiler is connected to the water network via a 1.5" thread like any other electric boiler. Everything was installed within a few hours and the boiler started heating immediately.

In addition to the financial savings and the uncomplicated installation, we especially appreciate the good feeling of using sustainable and environmentally friendly energy. It is a reassuring feeling to step into the shower knowing that the warm water was heated by the power of the sun and at no additional cost.

For us it is clear: the fothermo 80 liter solar hybrid boiler is one of the best investments we have made in recent years. We can recommend this system without reservation and hope that other interested parties can also benefit from the advantages of this innovative product.
