We transform energy into heat
Discover our sustainable solutions through our air source and geothermal heat pumps with the latest technology and the use of natural refrigerants.
AIR SOURCE
The range of Volta A-O monobloc air-to-water heat pumps takes air source heat pumps to another level.
Its careful design, along with its features and performance, make this air source heat pumps perfect for any home. Thanks to the use of natural refrigerant, we can heat water to temperatures above 70ºC, making it an ideal system for both renovations and new construction.

Natural refrigerant
The natural refrigerant R290, also known as propane, is already used in many appliances such as refrigerators, aerosols, and others. In this case, we use it to produce heating, cooling, and domestic hot water for your home. Why?
- It is a natural gas and is not produced synthetically.
- Its global warming potential is almost zero (GWP: 3).
- It achieves greater efficiency and better performance.
- We can work in exceptional external temperatures.
- Production of hot water above 70ºC.
- The use of propane allows heat pumps to be an option for home renovations.
HOME RENOVATION
By achieving water temperatures above 70ºC, we can use these systems in installations that aim to replace gas and oil boilers, as we can work with radiators.
SAVINGS
The high efficiency of these systems allows us to reduce heating costs by up to 80% compared to fossil fuels.
ALL-IN-ONE SYSTEM
With just one outdoor unit, we can produce heating, cooling, and domestic hot water for the entire home, without the need for refrigerant between the outdoor unit and the interior of the house, only water.
LOWER ENVIRONMENTAL FOOTPRINT
The R290 refrigerant, being a natural gas with virtually no effect on global warming, allows us to reduce our impact on the environment.
PERFECT FOR EXTREME TEMPERATURES
The operating range of this aerothermy system, thanks to R290, is so wide that we can produce high water temperatures even in situations with extremely low or high external temperatures.
Unique Non Stop Defrost (NSD) system in the market
Volta has developed the Non Stop Defrost (NSD), a new defrost management system that allows for greater effective power with Volta aerothermal heat pumps. The NSD allows the heat pump’s compressor to decrease its speed without stopping its activity. This innovation allows for faster defrost cycles and generates greater effective power for the installation.
GEOTHERMAL
The Volta geothermal heat pump range is one of the most advanced on the market
The Volta water-to-water heat pumps are heat pumps with variable-speed compressors and inverter technology, which allows the Volta geothermal heat pump range to be one of the most advanced on the market, achieving unique efficiencies and adapting to any installation in the most efficient way possible, reducing installation costs and saving space as no external components are needed.

Geothermal heat pumps with inverter technology and variable-speed compressor
All our water-to-water heat pumps have variable-speed compressors and inverters, allowing us to adapt the power of our heat pump to the demands of the home with the widest modulation range in the market. Moreover, with a single unit, we can heat or cool the entire house. Thanks to our technology, we achieve very compact installations, saving space in the technical room that can be used for other purposes.
LOWER INSTALLATION COST AND HIGHER PERFORMANCE
Having inverter technology and variable-speed compressors allows us to adapt to the needs of the home without oversizing the installation, which would result in a larger technical room and oversized wells. This way, we save money and space.dinero y espacio.
HEATING, COOLING, AND DHW (DOMESTIC HOT WATER)
With a single unit, we can climate control the entire house, achieving a very compact technical room and avoiding the installation of external modules for cooling, saving between €2,500 and €3,500.
ALL-IN-ONE SYSTEM
Thanks to modulation and the ability to adapt the power to the demand of the home, we avoid the installation of booster groups and inertia tanks, resulting in significant installation savings.
LOWER ENVIRONMENTAL FOOTPRINT
Heat pumps are renewable energy systems, which drastically reduce our carbon footprint.
HIGHEST PERFORMANCE
The seasonal performance factor (SPF) increases considerably since the heat pump adjusts the power to demand variations, avoiding the use of the compressor at maximum power most of the time. This translates into greater savings compared to the competition and a longer lifespan.
Superheat System
The Superheat system allows us to increase and almost double the performance of the heat pump by harnessing the extra energy extracted from the home and the compressor to simultaneously produce DHW while heating or cooling. Additionally, this allows us to heat water up to 70ºC without the need for electric resistance, and it is essentially “free.”
Furthermore, by installing a 3-way valve, we can heat the swimming pool for free when the heat pump is providing cooling. Similarly, just like with DHW, we can heat the pool while heating the house.
We achieve this by installing an intermediate heat exchanger that utilizes the heat generated in the compressor discharge during heating, and the heat extracted from the home during cooling.

The world’s only geothermal heat pump with natural refrigerant
Our geothermal heat pumps, Volta W range is the only ground source heat pump with natural refrigerant for indoor installation. The Volta development team has managed to develop this heat pump with the refrigerant limitations for indoor installations, making it a unique model worldwide.
FIRST GEOTHERMAL HEAT PUMP FOR RENOVATION
Thanks to the use of R290, we can achieve temperatures above 70°C, making it perfect for both new construction and renovation projects, as it can be used in homes with radiators.
MINIMAL REFRIGERANT CHARGE
We comply with regulations regarding refrigerant charge. It is below 150 grams, so no ventilation system is required for the indoor installation of this unit.

PHOTOVOLTAIC HYBRIDIZATION
The future is based on the mix of all renewables
Volta heat pumps incorporate the management of hybridization with systems that generate electricity from renewable sources.
Advantages
- Reduced electrical consumption while optimizing the operation of the heat pump in a unique way.
- Patented technology.
- Facilitates achieving self-consumption.
In case of excess electricity production, the heat pump activates and modulates its power to consume only the excess electrical energy, achieving a “zero” balance between production and consumption. This is only possible thanks to Volta’s advanced control strategies and the performance and modulation capacity of Volta heat pumps.
If at the time of solar surplus the house is already at the designated temperature, the heat pump adjusts the surplus settings (previously configured), taking advantage of this surplus and converting electrical energy into thermal energy, achieving a conversion of 1 kW electrical to 4-5 kW thermal, and introducing this excess energy into the house (raising the house temperature or increasing the DHW temperature), thus avoiding the use of batteries to harness these surpluses, resulting in significant savings.
