The Three-Way Diverter Valve on Your Burnham Boiler

The three-way diverter valve directs hot primary water either to the heating circuit or to the hot-water plate exchanger. When it sticks you get heat but no hot water, hot water but no heat, or radiators warming when you run a tap.

On Burnham systems — including models such as Alpine, ES2, Series 2 — a failing three-way diverter valve often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Burnham part.
