Success Story: John’s Transformation

Homeowner John noticed longer heating times from his old boiler during winter. After following our steps to drill baffle holes, he reported improved heating times and energy savings.

Understanding Baffles:

Baffles create turbulence inside the boiler, enhancing heat transfer between water and metal walls.

(Quote: "Baffles are essential for optimal combustion," Dr. Green)

Step-by-step Guide:

  1. Identify suitable location for drilling near turbulent water flow.
  2. Mark drill point with a permanent marker.
  3. Securely support and cool boiler before drilling.
  4. Start with small pilot hole, then gradually increase bit size.
  5. Monitor water flow during drilling to avoid over-drilling.
