Accumulative indirect heating boiler with a capacity of 95 liters from one of the leading European manufacturers of domestic water heaters, the Czech company Drazice. Mounted only in vertical floor position. Reassigned to work with the heating system (during the heating season) or with connection to solar collectors and other similar solar systems (during the summer). The surface area of the built-in tubular spiral heat exchanger, through which the heated coolant is passed, is 1.08 m2, which is quite enough to transfer high heat output (up to 24 kW).
The temperature of the heat carrier can reach 110 °C and pressure up to 10 bar. At high temperatures of the coolant, a 95 liter volume warms up from 15 to 75 °C in just 14 minutes. The internal tank of the Drazice OKC 100 NTR water heater is made of high-quality cold-rolled steel sheet and is designed for a working pressure of up to 6 bar. The surface of the inner tank is protected by heat-resistant nickel-free enamel.
Additional protection of steel against corrosion is provided by a large magnesium anode. The design of the device provides a service hatch that allows you to carry out internal work to remove scale, sediment and water stone. There is a clear heating indicator and a simple temperature control system. Another important advantage of this water heater is reinforced polyurethane foam thermal insulation, the thickness of which reaches 42 mm.

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. |
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. |
