Simple ■ Valves and components are fully preassembled as well as fully wired ready for connection

Efficient ■ High transmission performance and low pressure loss thanks to microplate plate heat exchanger

SYSTEM/BASIC DIAGRAM

FRESH HOT WATER STATION WITH HIGH-EFFICIENCY PUMPS

DESCRIPTIONThe TacoTherm Fresh Peta (C/CL) fresh water station is used for on-demand preparation of domestic hot water in accordance with the continuous flow principle. It retrieves the heat from the storage tank of an existing or new heating system, which uses solid-fuel boilers, heat pumps, solar systems, etc. as a heat source. The station replaces the storage of hot drinking water and thus provides a high degree of protection against Legionella by avoiding water stagnation.

INSTALLATION POSITIONVertical wall-mounting in the vicinity of the hot water storage tank or on the tank itself.

OPERATION Drinking water is heated to the defined dispensing temperature in the TacoTherm Fresh Peta (C/CL) in accordance with the continuous flow principle. The integrated heat exchanger is supplied with as little hot water from the storage tank as is required to maintain a constant dispensing temperature.

A low return temperature of the hea-ting water to the storage tank can be expected owing to the special design of the heat exchanger. In recording the temperature difference and flow rate data, the electronic regulator simultaneously records and stores the quantity of heat consumed. In addition to an additional circula-tion pump that can be installed, the TacoTherm Fresh Peta (C/CL) can also be supplied with a switching valve for dual-zone return stratifi-cation. The primary pump, circulation pump as well as load valve are controlled by the integrated regulator in ac-cordance with specifications.

BUILDING CATEGORIES ■ Apartment blocks ■ Housing estates ■ Multiple dwelling units ■ Residential care facilities and hospitals

■ Administration and service buil-dings

■ Hotels and restaurants, industrial kitchens

■ School buildings and sports faci-lities

■ Commercial and industrial buil-dings, industrial facilities

■ Facilities with partial use – for ex-ample barracks, camping sites, etc.

Fresh hot water station for hygienically heating drinking water in accordance with the continuous flow principle with and without dual-zone return stratification of the storage tank.

EXAMPLE FOR INTERPRETING THE FLOW RATE AND PRESSURE LOSS DIAGRAMS Given

■ Hot water dispensing volume: 63 l/min

■ Primary heating flow temperature: 70 °C

Sought ■ Hot water demand (l/h) ■ Primary heating return temperature in °C

■ Secondary pressure loss in mbar ■ Primary pressure loss in mbar

Approach ■ In Diagram A) the hot water demand at the intersection point of the dispensing volume of 63 l/min and primary flow temperature of 70 °C is 3800 l/h.

■ In Diagram B) the primary pressure loss for a hot water demand of 3800 l/h is 600 mbar. The pump delivery head is 700 mbar, discounting the pressure loss this gives rise to a residual pump head of 100 mbar (Δp).

■ In Diagram C) the primary return temperature for a given dispensing volume of 63 l/min and the selec-ted flow temperature of 70 °C is 19.7 °C.

■ In Diagram D) the secondary pres-sure loss for the given data is 450 mbar

NOTE

REQUIREMENTS FOR FLOW MEDIA

The stations heat interface units use a copper-soldered stainless steel plate heat exchanger as standard. It must be checked prior to use in the framework of system planning whether the issues of corrosion protection and scale formation have been sufficiently taken into account in accordance with DIN 1988200 and current drinking water analyses according to DIN EN 8065. See datasheet „Plate Heat Exchanger Requirements - Limit Values for Drinking Water Quality“.
