Shared boiler rooms are on the rise
News | 28. 6. 2018
Where one boiler is not enough, cascade boiler rooms take over; it is a system that connects several boilers together. This design can be used wherever there is a need for high output without any heat supply outages. Connecting smaller boilers allows for a continuous regulation of an output of up to 3.040 kW.
Where can be cascade boiler rooms used?
Their options of use are truly broad. We have installations in residential homes, hotels, or office buildings or schools. When you need to heat up a large building, there are not many efficient options to do so. If there is gas connection, the cascade boiler room is an ideal choice in terms of no-maintenance demands and reliability. As far as the cost is concerned, it can even compete with remote heat sources, namely thanks to the decreasing cost of gas, as well as the cost of condensing boiler technology.
How does a cascade boiler room work?
The principle is basically simple: it is a connection of several smaller boilers into one functioning unit. The boilers communicate with one another using special regulators that receive information about the current heat consumption and connect or disconnect the individual boilers based on that information. The advantage of this solution when compared with one large boiler is the wide range of output available according to the current heat or hot water consumption.
The cascade boiler rooms, i.e. the connection of several smaller boilers in order to ensure heating and thermal comfort, have...
The assortment of products and services is not only represented by THERM boilers, but also sophisticated systems for the connection of additional boilers into a series in the cascade boiler room...
Is there a universal set or is the cascade boiler room customised?
It always depends on the situation at the specific installation site, we could say that each cascade boiler room is an original, built according to the customer’s needs. However, the basic construction elements are mostly the same, an average boiler room has three to four boilers, THERM 45 KD.A or THERM 90 KD.A, according to the required output. They are boilers that we commonly sell, with minimum space demands, so the new boiler room can easily fit instead of the original one, leaving enough space for accumulation tanks or another technical room. The use of the standard boilers allows us to reduce the total cost of the boiler room.
When one of the boilers stop working, does it put the entire system out of operation?
No, and that is the second great advantage. You can basically work without any downtime. When any of the boilers malfunctions or has to be shut down, the remaining boilers take over its output. The output temperature in the system may drop by a few degrees temporarily but the consumers will barely notice that. When the boiler is not working as it should, the automatic diagnostic system is activated and informs the service technician. Therefore, there are not any long-lasting outages.
Are cascade boiler rooms more suitable for older residential homes or new buildings?
Boiler cascades can be used both in reconstructions of older coal-fired boiler rooms and in the construction of new houses. Both the investor and the housing unit owners have a chance to save on the initial investment as well as the operating costs. In older residential homes, you may come across situations that are difficult to solve, when it is a problem to ensure the flue of condensing boilers that have been installed with outlets into the common chimney paths that, however, were not prepared. In such cases, a common boiler room is an ideal solution, but it is difficult to explain to the housing unit owners who have already invested into a new boiler. There are also worries about the system of common heat and hot water bill for the common boiler room. How to set it so that it is fair and no-one is paying for their neighbours. Fortunately, we are also able to ensure all of that thanks to modern meters at the points of consumption.
You have been involved in cascade boiler rooms for many years, what has changed in their development?
The cascade connection of gas boilers is still an innovative method in the technology of heating systems. Even though the principle is basically simple, the optimal solution stands on the many years of our internal development and testing. The current trend is boiler communication via a new generation of regulations, using the information about the outdoor temperature via equithermal sensors, and the related automated optimization of the heating programme.
