Hygienic thermal store
Sanicube/HybridCube

Think DHW hygiene when buying a heating system

ROTEX has been making thermal storage tanks for optimum water hygiene for more than 25 years. The design of the storage tanks has been continuously optimized to ensure that the heated domestic water only stays in the storage tank. This means that neither deposits nor bacteria can arise.

Product description

The hygienic ROTEX thermal store

The ROTEX thermal stores were conceived in accordance with the latest thermal technology and water hygiene requirements. Its structure is fundamentally different from normal large volume hot water storage tanks. As a result of its design concept it delivers hygienically perfect hot water at any time. The actual heat is not stored in the domestic water itself, but in the storage tank water which is clearly separated from it. The optimum tank layering ensures that a supply of hot water is always available.

Application

Variable in use

The heating of the storage tank water, and thus the charging of the storage tank, can take place using various different heat sources:

  • With heat generator: Boilers, heat pumps or remote heat generate the heat that is introduced via the stainless steel heat exchanger
  • With solar energy: E.g. via the ROTEX solar system.
  • With an electric immersion heater: The hot water (domestic) is heated by an electric immersion heater made of stainless steel which is immersed in the storage tank water

Two different thermal store versions

Sanicube Solaris: This thermal store is the ideal addition for a oil or gas condensing boiler. In combination with the ROTEX Solaris solar system, the free-of-charge power of the sun is exploited in a highly-effective manner for hot water generation and heating support. This combination convinces by its highest level of energy efficiency thanks to low heat losses, perfect water hygiene and unlimited hot water convenience.

ROTEX HybridCube: We have developed the HybridCube specially for combination with a ROTEX air-to-water pump HPSU. This thermal store is designed for low flow temperatures while providing highest DHW convenience. It is the heart of the ROTEX heat pump system, stores the heat obtained then transfers it to the heating system at the required time. n combination with the ROTEX Solaris solar system, the free-of-charge power of the sun is exploited in a highly-effective manner for hot water generation and heating support.

Also for large-volume hot water demand

The ROTEX thermal store can be adapted flexibly to your individual hot water requirements. For this application several thermal stores are connected together in a modular fashion so that even output distribution is achieved and output capacities can be created of virtually any size.

Structure and function

The ROTEX thermal store principle

The drinking water is contained in a high-performance heat exchanger made of durable stainless steel (INOX). Your drinking water remains perfectly hygienic.

The storage tank water is added at commissioning and serves only for thermal storage. It is not exchanged and consumed.

Energy saving: The inner and outer walls are impact-resistant polypropylene, the space in-between is filled with highly heat insulating foam. This results in very good heat insulation values and minimum surface losses. This protects the environment and your wallet.

Low scaling: On commissioning, the storage tank is filled with tap water which is not exchanged during operation. Thus, only the lime contained in this water can be deposited; all the heat exchanger pipes remain free of limescale, as does the electric immersion heater, which is available as an option. On the inner surface of the heat exchanger pipes, the high flow speed when the water is removed releases smaller scale deposits.

Long-life and safe: The materials used (plastic and stainless steel) ensure the ROTEX thermal store has a particularly long life.

Hot water of the highest quality

The structure of the ROTEX thermal store ensures optimum water hygiene since the water to be heated is carried in a pipe system. Deposits of sludge, rust, sediments and even the generation of dangerous legionella bacteria which can arise in large volume tanks are not possible. The tank temperature of the ROTEX thermal store can be reduced from 60 °C to 50 °C, according to DIN 1988-200. The amended DIN 1988-200 permits reduction of the tank temperature from 60 °C to 50 °C in central hot water storage tanks with increased water exchange rates (in Germany).

It‘s better to trust experience

ROTEX has been making thermal storage tanks for optimum water hygiene for more than 25 years. The design of the storage tanks has been continuously optimized to ensure that the heated domestic water only stays in the storage tank. This means that neither deposits nor bacteria can arise.

 

 

Energy efficiency class

September 2015: Energy label now also for heating

The energy labels provide reliable efficiency classes. These labels will make it easier to compare individual heating products and decide which ones to buy.
