Contemporary plays can be considered modern in the sense that they reflect current societal issues, values, and cultural norms. They often incorporate modern technology, language, and themes that are relevant to today's audience. However, the term "modern" can also refer to a specific historical period in theater, typically the late 19th and early 20th centuries, so in that sense, contemporary plays may not be considered modern. Overall, the classification of contemporary plays as modern depends on the context and definition being used. **

A boiler is a closed vessel in which water or other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications. Boilers can be fueled by various sources such as natural gas, oil, coal, or electricity. They are commonly used in residential, commercial, and industrial settings to provide heating and hot water. **

I'm sorry, I am not able to physically inspect the boiler to determine if it is broken. It would be best to have a professional technician inspect the boiler to determine if it is broken or not. If you are experiencing issues with your boiler, it is important to have it checked by a qualified professional to ensure it is functioning properly and safely. **

The power consumption of a gas boiler or combi boiler can vary depending on the model and size of the unit. On average, a gas boiler typically consumes around 2,000 to 2,500 watts per hour when in use. This translates to approximately 48 to 60 kilowatt-hours of electricity consumption per day if the boiler is running continuously. It's important to note that energy-efficient models may consume less power, resulting in lower electricity bills. **

The main difference between a conventional boiler and a condensing boiler is their efficiency in utilizing fuel. Conventional boilers typically operate at around 70-80% efficiency, while condensing boilers can achieve efficiencies of 90% or higher. This is because condensing boilers are designed to capture and reuse heat that would otherwise be lost in the flue gases. As a result, condensing boilers are more environmentally friendly and can help homeowners save on energy costs in the long run. **

A gas boiler is a heating system that uses gas as its fuel source to heat water, which is then circulated through radiators or underfloor heating systems to provide warmth in a building. The boiler heats the water by burning natural gas or propane in a combustion chamber, and the heat is transferred to the water through a heat exchanger. Gas boilers are commonly used in residential and commercial buildings to provide central heating and hot water. **

Without more specific information or context, it is difficult to determine if the Buderus boiler is defective. Factors such as age, maintenance history, and any reported issues would need to be considered. It is recommended to have a qualified technician inspect the boiler to diagnose any potential defects and determine the best course of action. **

A boiler typically does not have a strong smell when operating properly. However, if there is a problem such as a gas leak or a buildup of soot or mold, it may emit a foul odor. It is important to regularly inspect and maintain your boiler to ensure it is functioning safely and efficiently. If you notice any unusual smells coming from your boiler, it is recommended to contact a professional technician to investigate and address the issue. **
