Wolf all-in-one heat pump is designed as a direct replacement for gas water heaters and combi boiler DHW. It provides mains-pressure hot water independently of any boiler. You will need a suitable indoor space (minimum ~5–8m³ for wall-mounted, ~10–15m³ for floor-standing) with sufficient ventilation or air duct connection.

The heat pump extracts heat from the surrounding air — too small a space will cause the room to cool too quickly, reducing efficiency. Alternatively, connect a 150mm air duct (floor-standing models) to draw from or exhaust to outside air, allowing installation in smaller spaces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"border-bottom:1px solid #e2e8f0;padding:.9rem 0 .9rem 1.5rem;position:relative;\"\u003e\n\u003cspan style=\"position:absolute;left:0;top:.9rem;color:#0d9488;font-weight:900;font-size:15px;\"\u003eQ\u003c\/span\u003e\u003cp style=\"font-weight:700;color:#1a3a5c;font-size:14.5px;margin:0 0 .3rem 0;\"\u003eIs this MCS certified?\u003c\/p\u003e\n\u003cp style=\"font-size:14px;color:#374151;line-height:1.75;margin:0;\"\u003eThe Becker \u0026amp; Wolf heat pump water heaters are A+ ErP-rated and CE certified.
