Find Answers Instantly
Our knowledge base and FAQ section are designed to provide quick solutions and information for common inquiries about your Kotel Sistemi equipment. Browse the topics below to find immediate answers to frequently asked questions and basic troubleshooting guidance.
How often should routine maintenance be performed on my Kotel Sistemi boiler?
The ideal frequency for routine maintenance depends significantly on several factors, including your specific boiler model, its operational hours, the type of fuel used, and the environmental conditions of your facility. While annual inspections are a common baseline for many industrial boilers, systems operating under heavy load or in demanding environments may benefit from more frequent checks. We highly recommend contacting our support team with your boiler's model and operational details. Based on this information, our experts can provide a personalized maintenance schedule tailored to ensure optimal performance, compliance, and longevity for your specific equipment.
What steps should I take immediately if I encounter a boiler emergency or malfunction?
In the event of a boiler emergency, such as a sudden shutdown, unusual noises, leaks, or any other critical malfunction, your absolute first priority should be ensuring the safety of all personnel. Follow your facility's established emergency protocols, which may include isolating the system, shutting off fuel supply, and evacuating the immediate area if necessary. Once safety is secured, immediately contact our 24/7 emergency support line at +386 2 456 7890. Be prepared to provide your contact information, the location of the facility, the specific boiler model and serial number if available, and a clear description of the issue observed. This information will help our team dispatch the appropriate support quickly.
