We use a Bosch geyser more gently - the yakness is super. Bought to replace an old HSV column. The supply of gas has completely changed from the previous one, although the new one is being used more often. The main argument for the purchase was that this model was manufactured in Portugal at the Junkers plant. The water temperature is precisely regulated and the water supply is stable. Completely copes with one-hour shutdown of two taps. Copper tank, plenty of service centers and spare parts at easy access, economy, stability of water heating The price is high, it was necessary to purchase adapters before installation  Vasyl Harasym: use Bosch Therm 4000 O WR 10-2 P few months |
The water heater has six rocks. The water quickly heats up with normal water flow, and if the water flow changes, the column goes out. It is important to regulate the water temperature. The element does not immediately catch fire when the weather gets wet, there is a strong wind, and the water heater starts to boil. hot water with normal water flow when the wick is turned on, it consumes approximately 10 m3 more gas per month, do not immediately burn the element, and with poor water pressure it does not work  Iryna Zaslavska: use Bosch Therm 4000 O WR 10-2 P more than year |
I already had a storage water heater with a volume of 150 liters at home, but we have a large family, as many as seven people, and there was still not enough water. Installing an even more capacious drive is not an option, it would warm up even longer. I had to install such a gas protochnik. He himself is not very expensive, but the project, the connection and everything else cost a decent amount. It's good that we already had a counter. Despite the promoted and well-known trademark, the price of this instantaneous water heater is quite moderate. I did not think that it would be possible to buy Bosch of the Portuguese (!) Assembly for such a modest amount. There is enough power to provide a decent pressure in one tap (up to 10 l / min) or an average pressure in the kitchen and the shower. In any case, we now have hot/warm water when we need it. The boiler and its power are mechanically controlled. It may not be as convenient as pressing the buttons, but it is much more reliable and the boiler continues to work during a power outage (its ignition is piezoelectric and does not require a network). There is overheating protection and gas control. All instantaneous water heaters have one serious problem, and this model also has it - any change in water flow affects its temperature. Of course, the dependence is not direct, the boiler smooths it out, but it's still not very pleasant to get cooler water in the shower because of the open tap in the kitchen. And in flow heaters, when receiving hot water with a high temperature, hardness salts are deposited inside the heat exchanger. Well, you also need to remember about a real chimney, made according to all the rules, it also required money |
