SBP 100 Plus & SBP 200/400 E Buffer Tanks
Buffer tank required
If a WPL is installed without the HSBC with its integrated buffer tank, then a buffer tank is required to be installed. We recommend these Stiebel Eltron tanks: the SBP 100 Plus, 26 gallon (100 liter); the SBP 200 E, 53 gallon (200 liter); or the SBP 400 E, 106 gallon (400 liter) buffer tank.
WPL installation without HSCB requires a buffer tank, indirect tank, and stand-alone WPM system controller

List of Accessories
| SK1 / WK2 Mounting Hardware WPL installation is recommended with our SK 1 T-mount rack or WK 2 Wall-mount rack. These racks elevate the WPL off the ground. Installation on a pad foundation is not recommended in areas with snow build up. Other important mounting considerations include requirements for air intake and outlet and proximity to salt water. All are detailed in the installation manual which should be consulted before siting. |
