Thermal - a spa hotel, Karlovy Vary

The PZP HEATING a.s. company can be proud to have completed two special projects with grey water recuperation with water-water heat pumps and separated capacitor located in the PAST tanks from TECHTRANS PT s.r.o. These applications were installed in the Thermal hotel and the Prezident hotel in Karlovy Vary.

The Thermal spa hotel offers comfortable accommodation with excellent spa and wellness care combined with a beautiful view over the Karlovy Vary town. A unique thermal swimming pool is also very popular which is fitted on the rock overseeing the town. The hotel offers accommodation in 273 luxuriously designed rooms.

New generation recuperator

The principle of heat recuperation is to return heating content of a heat-carrying medium e.g. of balneological waters, back to the process of the heating system.

The used heating content of balneological waters is determined by the following values:

  1. Measurable water heat: approx 1.15 [kWh/(m3 K)]
  2. Amount of water: [m3]
  3. Water heating: [K]

It is necessary to supply approx 12 kWh of heat to heat up one bath of balneological water -approx 0,3 m³ with 35 K = 45°C - 10°C.

When returning this heat back to the process by a heat pump, we have to use about ¼ of this energy = approx 3 kWh for the drive of the pump.

Waste water flows back to canalisation as cold as is the temperature of the fresh water from water mains.

The calculation is simplified; it does not include the varieties of the system and its heat losses.
If requested, it is convenient to increase the use of the heat pump by extending its application also for air-conditioning of the building.
