236 200 1007 Horizontal 300 L stainless steel DHW cylinder with a larger XL 316L heat exchanger for efficient hot water production.
The 300H-XL-LE1 provides a larger horizontal solution for projects with greater domestic hot water demand. The low vessel layout can save space where room height or service access is critical.
The 30 m AISI 316L heat exchanger supports efficient heat transfer and stable hot water performance. This makes the model suitable when both storage volume and heat pump efficiency are important.
The connections are grouped on one side, helping pipework stay clear and allowing the installation to be finished professionally.

| Safety requirements |
| The storage vessel must always be protected against overpressure. We recommend installing a safety valve with inlet combination, a Nexus sanitary expansion vessel and a Nexus expansion vessel for heating systems. The required expansion capacity must be calculated according to the total system volume and operating conditions. |
