1. Overview
This document provides the necessary information for installing a
Stiebel Eltron WPL A2W premium heat pump in conjunction with
the HSBC 300 Integral. It includes the most critical details on the
installation process. Some steps have been left out or only briefly
explained to maintain the brevity of this document. For extended
explanation on the components discussed in this document, con-
sult the manual dedicated to the specific component.
1.1 WPL 15 A2W Premium & WPL 25 A2W Premium
The WPL is an air to water monobloc heat pump. The refrigerant
circuit is self-contained within the unit itself. There are two sizes
available: WPL 15 A2W Premium & WPL 25 A2W Premium. These
devices are in the 2 and 4 ton size classes, respectively.
The WPL is capable of heating or cooling a water/glycol mixture
flowing to the unit. There are two water connections on the unit
that must be connected to the HSBC 300 Integral. A 6.75 kW back-
up element is included inside the WPL to supplement the heating
capacity.
1.2

HSBC 300 Integral

The HSBC 300 Integral integrates a system buffer, a DHW tank,
circulation pumps, and system controller into one package. The
buffer is a steel 26 gallon tank and the DHW tank is a 72 gallon
glass-lined tank heated by an indirect coil. The HSBC contains the
necessary pumps and diverter valves to use the WPL heat pump to
heat or cool the buffer tank, and to heat the DHW tank, with the
DHW tank having priority.
1.3

FET

The FET is an optional room thermostat which includes function-
ality for temperature control from within the conditioned space. It
also allows for adjustment of other basic system settings.

1.4

AF PT Outdoor Sensor

The AF PT outdoor sensor is a PT1000 sensor in a housing designed
for mounting on an exterior wall. This sensor is needed for ambi-
ent temperature feedback to the system controller.
1.5

System

The WPL and HSBC work together as an integrated package. It is
a compact means of providing a building's heating, cooling, and
DHW demands from a single appliance. This requires piping be-
tween the two units, and to the buildings heating/cooling delivery
system. For the DHW system, all that is needed is to run the cold
water connection to the HSBC, and to run the hot water connection
out to the tapping points. Some additional components such as
expansion tanks and air vents are necessary just as in traditional
systems.
