1. Description of construction
The storage tanks are used as accumulators that store thermal energy produced by the solid fuel boiler and
this energy is then continuously passed to heating system of central heating and hot service water.
The storage tanks constitute an accessory to:
•Systems with heat pump
•Solar systems
•Solid fuel boilers.
The storage tanks have 8 connections on the front side and 1 on top, allowing the connection of different
options. As standard the tanks are equipped with three sockets for sensors and water drain valve at the
bottom of the tank. Storage tanks can be supplied without thermal insulation or with thermal insulation.
The tank is removable and made of soft polyurethane foam. If we want to install a solid fuel boiler in cascade
with boiler on heating oil or gas boiler, with a fireplace and solar panels then the installation of storage tank is
recommended. In case of connecting the solar panels it is necessary to separate heating water circuit from
the antifreeze circuit in the solar system for example by using a external plate heat exchanger.
It is also recommended in case of boilers that are adapted to operation in an open system and you want to
have an installation working in a closed system. The tanks are not enamelled therefore they only are
adapted to the storage of neutral media (e.g. demineralised heating water, glycol, etc.). The maximum
allowable operating pressure in the tank is 3 bar (0.3 MPa).

2. Instructions for product disposal after its service life expiration
VIADRUS a.s. is a contractual partner of the firm EKO–KOM a.s., its client number being F00120649.
Packages are in compliance to ČSN EN 13427.
Because the product is constructed of common materials its individual parts are recommended to be
disposed through a firm dealing with waste collection and disposal.
The heater wrapping should be disposed of in following way:
- plastic foil, cardboard cover and the wooden pallet into the common waste
- metal strap for strapping – through a firm dealing with waste collection and disposal
- wooden base, is designated for a single usage and no longer can be used as a product. Its disposal is
subject to Act. 477/ 2001 Sb. a 185/2001 Coll.as amended.
