GB - Operational mounting regulations
1. Description
Accumulation tanks serve accumulation of excessive heat from its source. The source may be a solid
fuel boiler, heat pump, solar collectors, fireplace inserts, etc. Some types of tanks allow combination of
connecting even multiple sources.
The NADO type tanks serve accumulation of heat in the heating system and allow heating or
preheating of HSW (Hot Service Water) in an inner tank. Incorporation of an accumulation tank in the
heating system with a solid fuel boiler allows an ideal run of a boiler at favourable temperature during the
boiler operation. The main benefit lies in the period of optimum operation (i.e. with maximum efficiency)
when the excessive unconsumed heat accumulates in the tank.
The tanks and potential tubular exchangers are made of steel, without the inner surface treatment, the
outer surface of the tank is provided with a protective paint. The tanks are manufactured in 500, 700 and
1000-litre volumes. Individual versions are additionally equipped with one or two tubular exchangers,
each of 1.5 m
2
area and an inspection hole of 182 mm clearance with an option of installation of an in-
built electric heating unit TPK.
The NADO type enables direct heating of HSW (Hot Service Water) in an inner enamelled tank, or
its preheating for next water heater. Connection to a boiler usually allows direct HSW heating in the inner
tank to the desired temperature whilst, on the contrary, connection to solar collectors or heat pump only
preheats HSW and another, e.g. electric, heater has to be used, in order to complete heating the water to
the desired temperature, or final electric heating has to be fitted in the accumulation tank which is enabled
either by the electric heating unit TJ 6/4“, or by the heating flange TPK.

tanks NADO 140v1.
The tank contains an internal enamelled tank with a volume of 140 or 200 litres.
NADO v2
Storage tank with screw gauge 210 mm for mounting of built-in TPK flange electric heating units and one
1.5 m
2
exchanger for connection of another heating system (e.g. SOLAR). The flange is blocked off in the
standard version.
The G6/4“ extension pipe cab be used for mounting of the TJ G 6/4“ electric
heating unit.
The tank contains an internal enamelled tank with a volume of 140 litres.
NADO v3
Storage tank with screw gauge 210 mm for mounting of built-in TPK flange electric heating units and two
1.5 m
