Heating maintenance and heating cleaning are not the same thing. Heating maintenance involves inspecting, testing, and adjusting the components of a heating system to ensure it is running efficiently and safely. This may include checking for any potential issues and making necessary repairs. On the other hand, heating cleaning specifically refers to the process of removing dirt, dust, and debris from the heating system, such as the furnace or heat pump, to improve its performance and air quality. While both are important for the overall function of a heating system, they serve different purposes. **

Insulation reduces the heating performance by preventing heat from escaping the building, which in turn increases the heating costs. However, in the long run, the reduction in heating performance and increase in heating costs are minimal compared to the overall energy savings that insulation provides. Insulation helps to maintain a consistent and comfortable temperature inside the building, reducing the need for excessive heating and ultimately saving money on energy bills. **

Yes, wet heating pipe insulation can be harmful as it can lead to mold growth, corrosion of the pipes, and reduced insulation effectiveness. Mold growth can pose health risks to occupants, while corrosion can weaken the pipes and lead to leaks. Additionally, wet insulation loses its ability to effectively insulate the pipes, reducing energy efficiency and potentially leading to higher energy costs. It is important to address and repair any wet insulation promptly to prevent further damage. **

To determine if the heating pipe insulation is made of asbestos, it is important to conduct a professional inspection or testing. Asbestos was commonly used in insulation materials in the past, so if the insulation is old or has not been replaced, there is a possibility that it could contain asbestos. However, visual inspection alone is not sufficient to confirm the presence of asbestos, so it is best to consult with a qualified professional to assess the insulation and determine if it contains asbestos. **

The correct insulation for underfloor heating is typically a high-quality thermal insulation material that is installed directly beneath the heating system. This insulation helps to minimize heat loss downward, ensuring that the heat is directed upwards into the room. Common insulation materials used for underfloor heating include extruded polystyrene (XPS) or expanded polystyrene (EPS) foam boards, which have high thermal resistance and are suitable for use with underfloor heating systems. It is important to choose an insulation material that is compatible with the specific type of underfloor heating system being installed. **

The underfloor heating may be cracking since the renovation due to a few possible reasons. One potential cause could be that the renovation process caused structural changes to the floor, leading to stress and movement that the underfloor heating system was not designed to accommodate. Another possibility is that the renovation work may have damaged the underfloor heating system itself, leading to leaks or other issues that are causing the cracking. It's also possible that the new flooring material or insulation used during the renovation is not compatible with the underfloor heating system, leading to uneven heating and subsequent cracking. It would be best to have a professional inspect the underfloor heating system to determine the exact cause of the cracking. **

It is possible that the heating circuit pump is broken after maintenance, especially if the maintenance involved any work on the pump or its components. It is important to check for any signs of damage or malfunction, such as strange noises, leaks, or lack of circulation in the heating system. If there are any concerns about the pump's functionality, it is best to have a professional technician inspect and repair it as needed. **

The cost of heating system maintenance can vary depending on several factors, such as the type of heating system, its age, and the extent of maintenance needed. On average, a heating system maintenance service can cost anywhere from $100 to $300. It is recommended to get quotes from multiple HVAC professionals to compare prices and services before making a decision. **
