Sample interview questions: How do you ensure proper insulation and protection of hydronic system piping in exterior or underground installations?
Sample answer:
-
Insulation:
- Use closed-cell insulation with a high R-value to minimize heat loss and prevent condensation.
- Ensure insulation is properly installed and sealed to prevent moisture penetration.
- Consider using a vapor barrier or encapsulating the insulation to protect it from the elements.
-
Jacketing:
- Select a corrosion-resistant jacket material such as PVC, polyethylene, or fiberglass.
- Protect exposed elbows, valves, and fittings with additional insulation or shielding.
- Secure the jacket tightly to prevent moisture infiltration.
