At the same time, the thermal power of the model is in the range of 7-21 kW. This is a fully electric model with which you can get heat without smoke and condensate. Equipped with a 2-circuit heat exchanger. If you buy an indirect heating tank, you can use the boiler to provide hot water.

But only when connected to a 230 V network, only 7 kW of heating can be used. If you need a higher thermal power (14 or 21 kW), you will have to connect to a 400 V network.

We korist three rocks. It's burning, we're talking about a two-kilowatt apartment of 45 m2. Inode 3kV is wet, in severe frosts 4k.V. There is a thermostat in the apartment, purchases are okay, it miraculously regulates everything. Spend a maximum of 1500 grams per month for scorching. Budynok-tseglyany, healer-day/night. We programmed for the night rate and it was cheaper. By installing a master under license for these boilers. Handy and economical in the bathroom. Nope.

They hung one in the guard house. There is no gas at the plant, coal is now in short supply and electric heating was the only normal option. Connected to a three-phase network 380v. It heats the duty room, the rest room and the locker room with the kitchen - about 100 square meters in total. It gives a lot of heat, even in severe frost (-20 and below) there is enough heat for the whole house. It burns electricity, probably, also decently, but that is no longer our concern. It is controlled and regulated very simply: a pair of buttons and a rotary knob. The control system works clearly, what temperature you set, it maintains exactly that. Moreover, the boiler does not always work at full capacity. He knows how to smoothly reduce power to the required. It all works on semiconductors, i.e. the system is quiet and reliable. There is a three-speed circulation pump with anti-blocking, a pre-installed mechanical pressure gauge, there is an overheating protection, a pressure relief valve and frost protection. Looks nice and is well put together. Everything fits neatly, nothing dangles and does not play. The Germans know a lot about materials and assembly)) When, six months after installation, it began to make a little noise, they called an authorized service, but they said that since they did not install the boiler (our factory locksmiths installed it), the boiler lost its 24-month warranty. It's still a little noisy. In the spring we will call servicemen for maintenance, then they will see what's the matter. use Vaillant eloBLOCK VE 9 month or more |
