Pros
Cons
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 |
We have been using it for three years. We heat our 45 m² apartment by turning on two kilowatts. Sometimes we turn on 3kW, and during severe frosts, 4kW. We have a thermostat in the apartment, purchased separately, and it regulates everything wonderfully. The costs are a max of €39.00 per month for heating. The building is made of brick, and the meter has day/night settings. We programmed it for the night tariff, and it turns out to be cheaper. It was installed by a licensed technician for these boilers. Convenient and economical to use. No  Valeriya: use Vaillant eloBLOCK VE 6 more than year |
