Do-It-Yourself Savings Project: Insulate Hot Water Pipes

2) Cut the pipe sleeve. Cut the insulation to the lengths needed. 3) Place the pipe sleeve. Place the pipe sleeve so the seam will be face down on the pipe. 4) Secure the pipe sleeve. Tape, wire, or clamp (with a cable tie) it every foot or two to secure it to the pipe. Steps for insulating your hot water pipes to reduce heat loss and raise

Performance enhancement of high temperature latent heat thermal storage systems using heat pipes

The figure shows that the energy storage rate in the PCM using a finned heat pipe is higher compared to a bare heat pipe. This suggests that inserting finned heat pipes will increase the rate at which heat can be delivered to the PCM during charging.

Thermal energy transfer around buried pipe infrastructure

The pipe had a thermal influence extending over 4 m (¿30D pipe) after 4 months. Ambient conditions and adjacent pipes interact thermally with the buried water pipe. Fluid in adjacent pipes can act as a heat sink due to induced convection. Thermal diffusion dominates in the low moisture content sand around the pipe.
