Voluminous and sturdy Czech floor-standing indirect water heater
23 May 2016 
Working with us in tandem with the Turkish solid fuel boiler Gorenje Ecoheat 6 CA. The combination turned out very successful. In winter, the boiler is enough for both heating and the water heater, in summer only the water heater circuit operates. There is plenty of hot water, and it heats up pretty quickly.
Thick steel enameled tank. The steel is quite thick, about 3 mm. In addition to high permissible pressure and a sense of reliability, this also adds over 100 kg of weight. The enamel protecting the tank is special. It is resistant to temperature fluctuations and has increased resistance to cracking and chipping. Additionally, this enameled tank is protected by a sacrificial magnesium anode. I think such protective measures are sufficient to not worry for at least three to four years. The internal spiral tube heat exchanger has a decent area of 150 square decimeters, ensuring rapid water heating. Comprehensive thermal insulation made of polyurethane foam with a thickness of 40 to 65 mm. This is quite substantial, so in the absence of recirculation, the water remains hot for about two days. Not all indirect heating boilers can boast such indicators. Servicing and cleaning the boiler is quite convenient thanks to a rather large hatch. The controls are clear and convenient; moreover, there is control available for an additionally installed electric heating element (we did not install it).
Very large and unrealistically heavy. It was extremely difficult to drag it to the installation site.
good model, I liked it

Large volume. Three hundred liters of water at a temperature of around 80 degrees, when diluted, turn into 600-700 liters of just hot water for the shower. Large heat exchange area. The total area is about 150 square decimeters, which allows heating water from the heating circuit even at a relatively low temperature of the heating water. Excellent thermal insulation. Nearly 70 millimeters of foam polyurethane effectively retains the water temperature. In 12 hours of inactivity, only 4-5 degrees are lost. Option to install an additional electric heater. To have hot water in the shower even when the solid fuel boiler is not operating, for example in the summer, I purchased a branded Drazice TJ 7.5 heating element. With a nominal power of 7.5 kW, it heats 300 liters of water in just over three hours. Separate control systems for the heat exchanger (working from the heating circuit) and the electric heater.
When operating on electricity, the heating element (TEN) quickly becomes covered with a thick layer of scale. The problem is that its specific power (in terms of area) is quite high, and the local water has considerable carbonate hardness. As a result, the heating element needs to be cleaned frequently.
