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 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, 750 and

1000-litre volumes. The 500-litre version is additionally equipped with a tubular exchanger of 2.5m

surface and the 750 and 1000 litre version with a tubular exchanger of 3.3 m

G1½" mm, with the possibility to install an electric heating element of TJ 6/4" series with an extended

cooling compartment, up to 6 kW.

The NADO type enables direct heating of HSW (Hot Service Water) in an inner enamelled tank,

or preheating of water for another water heater. Connection to a boiler usually allows direct HSW

heating in an 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

reheat the water to the desired temperature, or final electric reheat has to be fitted in the accumulation

tank which is enabled by a TJ 6/4" series electric heating unit with an extended compartment of up to

6 kW output.

2. Designing the size and connection of ACCU tank to the heating system

An ideal size of the accumulation tank is designed by a design engineer, or a person sufficiently

qualified to design heating systems.

Product assembly must be implemented by an authorised person (confirmed in the warranty

certificate).

Important: When putting into operation, water has to be filled first into the inner tank for HSW

and the operating pressure inside it has to be kept, only then heating water can be filled into the

outer accumulation tank, otherwise the product may get damaged!

The manufacturer explicitly emphasises the necessity of being particular in testing the tightness

of the heating circuit (radiators, piping joints, floor heating, etc.) with the connection of the

accumulation tank.

may occur above the maximum operating pressure of 0.3 MPa, if the heating system is

pressurised to higher than the maximum operating pressure, the inner enamelled tank may get

permanently damaged!

No stop fitting can be put between the security fitting of the heating circuit and the accumulation

tank!!
