The valves on heating pipes are typically ball valves or gate valves. Ball valves have a spherical disc inside that controls the flow of water by rotating the handle, while gate valves have a gate or wedge that moves up and down to control the flow. Both types of valves are used to regulate the flow of hot water through the heating system and can be manually operated to adjust the temperature or shut off the flow completely. **

The improved performance of the energy-saving pumps may lead to increased usage, as they are able to distribute heat more evenly and effectively throughout the system. Additionally, the replacement of old pipes with newer, more efficient ones may also contribute to increased energy consumption, as the system may be able to operate more efficiently overall. **

Pipes are not allowed to be installed in load-bearing walls because doing so can compromise the structural integrity of the wall. The placement of pipes can weaken the load-bearing capacity of the wall and potentially lead to structural failure. Additionally, installing pipes in load-bearing walls can make it more difficult to access and repair the pipes in the future, as it may require cutting into the wall and compromising its strength. Therefore, it is important to avoid installing pipes in load-bearing walls to ensure the safety and stability of the building. **
