1. Inquiry
An inquiry for the heat pump should contain the following data:
- Thermal losses of the building (ought to be given in the central heating design)
- If the thermal losses are not known: we can calculate the TL and it is necessary for this to have the constructional drawing documentation of the building (floor plans, sections, views and structure compositions – building materials, insulations, windows etc.)
- In case neither of the previous information is available, the building can be measured during a personal consultation visit or the calculation can be based on the actual energy consumption
- The heat pump type (air – water, earth – water, water – water); if in doubt as to the choice, with pleasure we explain you advantages and disadvantages of those systems and we will assist you in the selection
- The heating system – floor heating, radiators, a combined system
- Service hot water warming – the number of supplied persons
- Contact
2. Personal meeting, quotation
- We prefer a personal meeting before making our quotation in order to know your definite idea and requirements
- Then the quotation ought to be complete for the whole machinery – i.e. the heat pump inclusive of regulation, a bivalence source, a buffer tank, a service hot water tank, transportation and assembly
- Through our assembly companies we are also able to present you a quotation for your heating system
3. Design and other legislation
- The design of the central heating is important from the point of view of the heating system which should be designed for the maximum thermal gradient of 50/45°C
- An inspection of the heating system at least is important in existing buildings
- A notice of construction shall be presented to the respective building office
4. Heat pump installation – assembly requirements
a) Air - water
- Minimum requirements – a foundation for the evaporator and a wall cutout in the event of split models
- Condensate drainning out and a wall cutout in the event of internal models
b) Earth - water
- An earth collector, horizontal (planar) or vertical (depth) one
- The permission based on the legislation in force
- The building permission
- The permission based on the law on dispose of waters
- The permission from the Czech mining office
c) Water - water
- Two wells (suction and drain) sufficiently distant each other
- Suitable composition of pumped water
- A minimum water temperature of +8°C all the year round
- Sufficient water flow rate verified by a pumping test taking two weeks at least
- The permission based on the legislation in force
- The building permission
- The permission based on the law on dispose of waters
- The permission from the Czech mining office
