Maximize efficiency by insulating hot pipes to prevent heat loss. Standard hot water pipe and radiator steam pipe insulation help keep the heat in your system. Typical heat protectors include:
- Glass wool or fiberglass pipe insulation: Lightweight materials that protect against very high temperatures and resist mold. However, they may irritate the skin, eyes, and respiratory system, so they are best used away from frequently used areas.
- Mineral wool insulation: Resists extremely high temperatures and works well on very hot pipes. Like glass wool and fiberglass, it may irritate and should be used away from living areas.
- Flexible elastomeric foams or rubber pipe insulation: Some insulations that protect against freezing also insulate against heat to a certain extent. While they prevent some heat loss, they are not rated for as much heat as fiberglass.
- Polyethylene: The most common cold insulator, it also protects hot pipes from heat loss. Insulate your home plumbing with this lightweight, durable, water-resistant material.
