Yes, the consumption of energy-saving pumps may increase when replacing heating pipes. This is because energy-saving pumps are designed to operate more efficiently and effectively with newer heating systems and pipes. 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. **
