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)
