Vaillant makes a \u003cstrong\u003eplate heat exchanger mandatory\u003c\/strong\u003e on every ecoTEC plus 80, 100 and 120 kW boiler. It separates boiler water from system water, protects the boiler from debris and lets the boiler run pressurised on an older or open-vented system. For a standalone installation not using Vaillant cascade hydraulics, the \u003cstrong\u003ePHE S 120-70 (0010025676)\u003c\/strong\u003e is the matching unit.\u003c\/div\u003e\u003c\/details\u003e\u003cdetails style=\"border:1px solid #008377CF; border-radius:8px; margin:0 0 10px 0; overflow:hidden;\"\u003e\u003csummary style=\"background:#008377CF; color:#ffffff; font-weight:bold; padding:12px 16px; cursor:pointer;\"\u003eWhat is the pump group and do I need one?\u003c\/summary\u003e\u003cdiv style=\"padding:14px 18px; color:#1f2d2b; line-height:1.65; background:#ffffff;\"\u003eThe boiler does not include a circulation pump.
