1 - Description
PS2F N+ Thermal Stores are intended for storing and subsequent distribution of thermal energy from solid-fuel red
boilers, heat pumps, solar collectors, electric boilers etc. This thermal store shall be always connected to a sealed
heating circuit with forced circulation. Thermal stores are tted with two anges; each can be tted with a suitably
sized tube heat exchanger depending on the selected application and required output. Mating anges for heat ex-
changers with either G 1” or G ¾” connections are supplied with PS2F N+ thermal stores. When no heat exchanger is
installed, a blind ange shall be used.
These heat exchangers are made of nned copper tubes that feature larger surface area and better heat transfer. The
lower heat exchanger usually connects to a solar thermal system and the upper one is used for DHW heating (contin-
uous) which limits signicantly the risk of Legionella bacteria formation. The tanks are also tted with nine G 6/4“ con-
nections to connect heat sources and heating system, four G ½“ ones for sensor sheaths and one G ½“ connection for
a safety valve. El. heating elements can be installed directly into the 6/4” connections.
1.1 - Models
Six models of 285, 479, 809, 932, 1509 and 2005 l capacity.
1.2 - Tank protection
The inner surface has no nish, no anticorrosion protection, the outer surface is lacquered in gray.
1.3 - Thermal insulation
Thermal insulation is available as a separate item. For easier handling, the insulation shall not be tted on the tank
until it reaches its denite place of installation. The insulation is made of eece, 100 mm thick, with a hard polystyrene
surface. It is closed by a quick lock.
1.4 - Connection points on the tank
2 anges with 210 mm inner diam.
8 side connections in a 90° sector, G 6/4” F thread
1 top connection, G 6/4” F thread
4 side connections for sensor sheaths, G ½” F thread
1 side connection for a 3 bar safety valve, G ½” F thread
1.5 - Packaging
Tanks are delivered standing, each screwed to its pallet, packed in bubble wrap.
Included in the package are gaskets and bolts for the ange.
2 - General Information
This Owners Manual is an integral and important part of the product and must be handed over to the User. Read care-
fully the instructions in this Manual as they contain important information concerning safety, installation, operation and
maintenance. Keep this Manual for later reference. The appliance shall be installed by a qualied person according to
valid rules and Manufacturer‘s Instructions.
This appliance is designed to accumulate thermal energy of heating water and distribute it subsequently. It shall be
connected to a heating system and heat sources. The equipment is suitable also for continuous water heating. In such
a case, the customer needs to buy a suitably sized heat exchanger (available as accessory) and have it installed into
the upper ange.
Using the thermal store for other purposes than above described (e.g. as a DHW tank) is forbidden and the
manufacturer accepts no responsibility for damage caused by improper or wrong use.

4 - Operation
In the thermal store, heating water is heated up from several heat sources like various types of hot-water boilers,
renewable energy sources (heat pumps, solar collectors), or electric heating elements.
The thermal store shall be connected to a heat source through G 6/4” connecting ttings. Should it be connected to a
solar thermal system, too, this shall be done through a suitably sized heat exchanger installed into the lower ange.
