Application
In a combination boiler system, a single unit handles both space heating and domestic hot water. The DHW flow switch is the critical link that detects when hot water is being drawn and commands the boiler to prioritize that demand. A faulty or worn flow switch can cause delayed hot water response or prevent the system from switching between heating modes. Replacing it with a genuine Burnham OEM part restores proper sequencing and reliable performance.
Why Choose Genuine Burnham OEM Parts
Genuine Burnham replacement components are manufactured to the same specifications as the original equipment, ensuring a precise fit and dependable long-term performance. Using OEM parts reduces the risk of premature failure, protects system integrity, and helps maintain warranty compliance where applicable.
