3. Technical data of heat pumps Hotjet

3.1. Technical data of heat pump Hotjet “ i “

New generation of heat pumps hotjet “i” is highly

functional while the price is still unbeatable. How did we

achieve this? By optimization of the design, careful

choice and serial production.

Basic information

• It is adjusted for installation into a building

• Source of heat is the energy of external air

• It works up to -20°C

• It is designed for unmanned water heating up to do

55°C.

• It is suitable for ﬂoor and radiator systems

• Regulation maintains heating of domestic hot water

(DHW)

• Compact construction does not require much space

• 2 levels of regulation with a possibility of extension

• Wired and wireless control

• Effective anti-corrosion protection

• Wide range of accessories

Advantages

•

The heat pump is not exposed to the outdoor

environment (water, snow)

•

Heat dissipations stay in the house

•

The heat which accumulates in the cellar can be

partially used (air exhaust dehumidiﬁes the cellar)

•

It is possible to extract heat from the foul air from

recuperation/ventilation

•

It is possible to preheat the source air by a solar

system

•

Noise of the unit is suppressed by a wall

•

Aerodynamic noise is mufﬂed by air conduits

•

It does not “provoke” thieves

• The condensate drainpipe can be carried out into

sewerage

Source of heat: suction air

Installation position

garage, cellar, workroom, utility room, farm building

Characteristics

External part of installation: there is none, just holes in

the wall and covering grate/shutter on the facade

Noise suppression:

•

Compressor scroll without mechanically movable

pistons and valves

•

Multiple spring-loaded housing of compressor and

cooling circuit

•

Solid compact baseplate

•

Multiply insulation against noise on the covers

•

Insulated air-conditioning pipeline

•

Optional installation of circular silencer (part of an air-

conditioning pipeline)

Space required: the heat pump takes up the area of

0.7m2. Upper cover height is 900mm. Coupling air-

conditioning sleeves take up approximately 50mm.

Defrosting: dynamically, according to need, by hot

gases

Condensate drain: by a hose into the drainage or by

a condensate pump

Control units:

AVS37 (standard)

•

Operator panel in a switchboard

•

Without spatial temperature reading (solved by

external thermostat)

QAA78 wireless unit (optional)

Combined spatial and operating device

Advantages of QAA78:

•

Heat pump, heating system and heating of DHW may

be controlled from any place in the house.

•

Spatial thermostat function informs the regulator of

temperature in the place where the unit is placed.

Support of connection to the heating system:

•

Connection without surge tank, directly to the heating

system

•

Connection with a surge tank point-to-point, four-point

•

Support for surge tanks with ﬂoating boiler

Surge tank (storage reservoir):

•

Is not necessary (requires consideration)
