Our HTi20 inverter heat pump is an innovative device that sets the direction for the development of the heat pump market. Thanks to our proprietary solutions, the HTi20 pump running on R290 propane operates at ambient temperatures below -20ºC, maintaining nominal heating power even at -10ºC. HTi20 is a high-temperature pump which heats water up to 60ºC, and can therefore be successfully used in both new and modernized buildings. Its aesthetic design in two versions will suit different architectural styles.
We are proud to present to your our new HTi20 inverter heat pump that sets new standards for heat pumps in terms of comfort, efficiency, ecology and design.
INVERTER HEAT PUMP HTi20
With the inverter technology, power can be modulated to adjust it to the current demand, which contributes to lower energy consumption, simplified installation and high comfort of use.
Higher seasonal efficiency.
Comfort of use.
Nominal power przy - 10ºC. Operation below -20ºC
With the Keep the Power System (KP System), the HTi20 pump maintains its nominal power even at very low ambient temperatures. Thanks to this feature, the pump can serve as the primary heat source.
Primary heat source.
Lowered bivalent point.
High quality is the main pillar of HKS LAZAR’s business philosophy in every phase of the product’s life cycle: from design, through production, to service coverage.
Restrictive production control.
Care for full customer satisfaction is one of our priorities.
Power adapted to the demand.
Cooling as standard.
Touch display panel.
Room temperature sensor as standard.
Two heating circuits as standards.
Hot tap water circulation.
Thanks to its high efficiency, power modulation and simple installation, the HTi20 heat pump is the investment for every project and budget.
Power adapted to current demand.
Very high COP coefficient, up to 5.02.
No registration requirement and no gas emission fees (the heat pump runs on R290 propane).
Broad operating range (-25ºC to +35ºC) - limited demand for additional heat sources.
Installation without a cooling license.
Renewable heat source.
R290 propane is characterized by zero destructive potential for the ozone layer (ODP=0) and a very low global warming effect (GWP=3).
We regularly attend major global conferences devoted to the development of natural refrigerant technologies.
Natural cooling medium R290(propane)
Since care for the natural environment is one of HKS LAZAR’s priorities, our heat pumps run on R290, a natural cooling medium (propane). This gas is neutral for the ozone layer and is characterized by negligible global warming effect GWP=3 (by comparison, the GWP of the most popular refrigerant, R410A, is 2088). This brings considerable relief to our environment.
However, our heat pumps running on R290 offer advantages to the user as well. Replenishing R290 is much cheaper, considering the rapidly growing prices of f-gases in connection with restrictions imposed on their production and use. First and foremost, our heat pumps will not be recalled, which can be the case for pumps running on f-gases (such as R410A).
The SMART unit contains a controller offering many functions for the user, an electric installation, a supplementary electric heater, a central heating/hot tap water switch valve, and a circulation pump. It is connected with the external unit by means of a communication cable included with the device.
The controller consists of a basic unit, an Internet unit, two inner temperature and central heating circulation sensors, an outer temperature sensor installed in the external unit. With this arrangement, the user can control two circuits (including one directly): heating and hot tap water, and can set schedules and perform weather adjustment.

Smart Tower control module
The SmartTower external unit is a complete boiler room, all in a single housing, which creates more space in the actual boiler room and saves installation time.
The inner unit was extended to include a hygienic hot tap water tank which supplies legionella-free, pure water, a buffer tank improving the performance of the heat pump and providing energy for de-icing, a heating water filter with a magnetizer, tap water and central heating diaphragm vessels, tap water and central heating safety valves, heating water pressure gage. Furthermore, it includes all elements of the Smart module: a controller offering many functions for the user, an electric installation, a supplementary electric heater, a central heating/hot tap water switch valve, and a circulation pump. It is connected with the external unit by means of a communication cable included with the device.
Additionally, the SmartTower unit can be fitted with an extra heating circuit with a mixing valve.

Pellets relates to a fuel that is still underestimated. The reason may be the fact that many persons are not familiar with use of pellet fired boiler for heating purposes. It may seem that use of biomass, namely sawdust or straw as a fuel in central heating boiler causes a lot of hassle and is labour-intensive. Nothing more misleading!
