Viadrus Hercules U22 C6 34.9 kW

Эта конструкция используется в Европе уже более двадцати пяти лет и действительно может называться проверенной временем. Котел оснащен практически вечным массивным чугунным теплообменником, состоящим из четырех секций. Чугун обеспечивает максимально равномерное распределение тепла и эффективный подогрев теплоносителя. Большая дверца для загрузки топлива. Для угля это не так принципиально, а вот для тех, кто топит дровами, это важный момент. Простой и надежный механический регулятор тяги и термоманометр. Невысокие требования к дымоходу. Отлично работает даже при низкой тяге. Очень большой зольник, который не требует частой чистки. Процедура чистки котла продумана и удобна.

Works on any solid fuel. He burned with different coals: gas, coking and anthracite. Anthracite, of course, works best - the smoke is cleaner and there is much less soot than gas and coking. After them, the heat exchanger and chimney have to be cleaned more often. Any tree can also be loaded, from small branches to large logs. Everything burns, but large logs burn longer and one load lasts about four hours. It provides a lot of heat and is more than enough for almost three hundred square meters of space. And in order to heat less often, I ordered the installation of a large, two cubic meter in size, heat storage tank. So two fireboxes a day are enough even in fairly cold weather. The water heater in the boiler is made of thick imported cast iron. The manufacturer gives it a ten-year warranty, which is good news. I think it will definitely be enough for my lifetime. The doors for loading fuel, cleaning ash and the heat exchanger are large and convenient. They close securely and keep out smoke. Easy connection. I connected it myself, nothing complicated. But I had to tinker with the installation, because the boiler is very, very heavy. The equipment is good. Everything you need for work is already included with the boiler. There is also a cleaning tool and a thermomanometer and draft regulator.

It can be adapted for gas, which provides an opportunity to save on solid fuel or if there are difficulties in obtaining coal or firewood. In this regard (in terms of fuel, that is), the boiler is practically omnivorous. You can heat it with coal, buy special firewood, or collect damp brushwood from the forest. It heats equally well, with no disruptions in operation, although the consumption varies significantly. However, it is best to use coal.
The efficiency is stated as 83%, if you believe the technical data. In reality, it's nowhere near that figure, because the boiler is operated under completely different conditions than those when the manufacturer measures the efficiency, and it's unclear how they measure it. But the boiler heats a large area adequately; I use mine for a private house, and it suffices for all the rooms. It doesn't smoke unless you accidentally close the draft damper, which happened once. If you open the damper, it stops smoking. No special skills or knowledge are required to use it. A normal boiler.
