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 |
The German company Vaillant has been developing products for climate systems since the second half of the 19th century. Today, the manufacturer locates facilities around the world and makes millions in profits by selling practical and ergonomic equipment. The eloBLOCK VE 12 electric boiler costs a lot, about $750. Let's see what features the unit is endowed with.
New design, old functionality
The product of a rectangular shape with dimensions of 740x410x315 mm and a weight of 24 kg is attached to the wall in any convenient place in the room: in the kitchen, in a niche, in a pantry. In 2019, the unit changed its design, so it became even thinner and sleeker. The device is equipped with a circulation pump and an 8-liter expansion tank. On the front panel there is an electronic control panel with a small display, which displays the temperature of the coolant in the circuit and error codes in case of malfunctions of the device.
Lots of heat
Heating elements with a power of 6 kW can work together or alternately, which is convenient when you need, for example, to reduce power with the advent of spring. The boiler is able not only to heat a room up to 120 square metres. m, but also to adjust the heating power from 2 to 12 kW in increments of 2 kW.
The unit can be connected to a thermostat to automatically provide a comfortable air temperature in the house, as well as to an indirect heating boiler, which easily solves the issue of hot water for domestic needs. Support for summer mode allows the boiler to work only to provide hot water.
Complete security
Circuit breakers prevent overheating of individual sections of the heating system, freezing of the liquid in the circuit, as well as overheating of the coolant.
In general, Vaillant eloBLOCK VE 12 is a good choice, as it fully meets the user's needs for heat and hot water, regardless of the season. But pricey. Almost the same Protherm Skat 12K will cost $100 less.
