The initial shot of gravel being poured into a pipe and the question about the cost of a heat pump installation.

The video shows a step-by-step installation process of a heat pump. It begins with gravel being poured into a pipe, followed by a tamper being used to compact the material. A spirit level is shown to ensure accuracy. Then, a person is seen placing a large black component, possibly part of the heat pump system, into position. The process continues with electrical wiring being prepared and connected, and a wrench being used to tighten bolts. Finally, a close-up of the heat pump unit is shown, with hands pointing to a label. The ad concludes with a shot of the complete heat pump system components arranged together.
