About Ambienta W

In modern low-energy houses, the biggest share of energy consumption is spent on hot water supply rather than on regular space heating. Therefore, the method of heating the water in an energy-efficient house is an aspect well worth considering.

Jablotron Ambienta W water heater uses natural and economic accumulation of heat in water. The storage tank has a built-in heat pump, which ensures ecological production of hot water throughout the day. Due to the integrated solution, the heat pump requires no outdoor unit, only two air ducts are installed through the exterior wall instead. The heat pump draws energy from the outdoor air, that is pumped through the ducts. Generated heat is then stored in a tank with a capacity of 250 liters (66 gallons).

Compared to larger heat pumps, Jablotron Ambienta W is a fully autonomous and structurally simple device with a low refrigerant content. This guarantees long-term operation, minimal maintenance and fewer service requirements. Combined with relatively low purchase price, Ambienta W is a great value-for-money water heating solution.

Ambienta W is part of the System 21 - HVAC concept for passive houses, where it contributes to the share of renewable energy sources within the overall energy balance.

Enjoy carefree and ecological hot water heating from Jablotron.

Jablotron System 21

Technology for energy-efficient homes of the 21st century


Optimal indoor environment – this is System 21 in short. It covers all technologies a low-energy house needs for a healthy and comfortable indoor environment: heating, ventilation, cooling and hot water supply. This makes System 21 a complex HVAC solution while being exceptionally affordable. How is that possible? The better the building envelope, the simpler, cheaper and less operationally demanding technology the house requires.

Each of the elements of System 21 was designed with the aim of flawless operation in mind. At the same time, we keep our technologies as simple as possible – for long-term operational reliability and minimal maintenance and service requirements.
