3.2.2
OPTIONS WHEN USING CALPAK X-FLOW ULTRATANKS
Regarding the dimensioning of the tank, Calpak suggests:
A Calpak X-FLOW with a 1,500 lt/h (1.5 model) supply heat exchanger can cover the needs of up to
25 rooms, assuming that:
1. The peak in demand lasts 1.30 hours or more, with uniform distribution.
2. Each shower lasts 20 minutes.
Obviously, this is not an absolute calculation, because a different approach may be required depending on
the needs of the project and the estimations of each engineer.

Calpak X-FLOW
SCENARIO 1:
a. A & B category hotel open throughout the year, Climate
Zone A
b. 40 persons (60lt/person/day)
c. Water temperature = 48 °C, peak = 1.5
hours, concurrency = 50%, tank = 2000 lt
d. 16kW heat pump, source start-up and shutdown
temperature: 54 °C and 55 °C respectively.
e. Month of reference: July
Duration of peak coverage by Calpak X-FLOW = 1:31:00
Duration of peak coverage by a conventional tank in the
same conditions = 0:50:00
minutes

Calpak has developed specialised software to ensure with accuracy the coverage of hot water
needs (DHW) in each individual case. If you wish, you may fill in the questionnaire (page
38) and send it to the Technical Department (export@calpak.gr) to receive a comprehensive
NOTE
technical report from our company, detailing with precision the function of the selected tank in
relation to the consumption profile of your client.
