NaturaTemp: engineers who design and install solar water heating
A company from the Galilee that designs, installs and supports solar water-heating systems for pools, private homes, hospitality and industry, across Israel.
What we do
NaturaTemp designs, installs and supports solar water-heating systems. The main source of heat is solar water-heating panels made of glass vacuum tubes; a smart controller shares the heat between the pool, the hot water, the jacuzzi and the heating by a priority order; and a heat pump or the existing boiler tops up only when the sun is not enough.
We do not sell a package from a catalogue. Every system is calculated for its site: how much heat is needed, in which months, what equipment is already there and where the panels can go. That is why every project starts with a site survey and a detailed quote.
Our systems run in private homes and a guesthouse in northern Israel, and we design and install across the country.
How we work
Four steps, the same for a 12 m³ pool and for a hotel.
A site survey and a quote
We measure the consumers (the pool, the hot-water demand, the heating), look at the roof or the space for the panels, the existing equipment and the piping, and send a detailed quote before any work. If the only place for the panels is in the shade, we say so: the system would not pay off.
Engineering design
The number of panels and their tilt, the storage volume, the controller's priorities and the role of the backup are calculated for your site. What the controller can do with existing equipment depends on the model, and the survey settles it.
Installation by our engineers
Our team installs the panels, the controller and the connections to the existing installation, and commissions the system with you, so you know what it does and how to see it on your phone.
Warranty and support
A 5-year warranty on the system, remote monitoring and support after the installation.
The team
Two founders: thermal science and engineering on one side, software and systems on the other.
Dr. Igor Demchenko
Founder, CEO, Chief Scientific Officer & Head of R&D
PhD engineer and original creator of NaturaTemp’s concept. Leads the scientific vision, thermodynamic modeling, vibration and spectral analysis, and R&D strategy for our renewable-energy HVAC systems and thermal battery technologies.
Denis Zeliger
Co-Founder, Chief Architect & CIO
Co-founder responsible for system and software architecture. Designs and leads the NaturaTemp platform across backend, IoT integration, data infrastructure, cloud services and client-facing applications.
Research and development
Alongside the installations we work on two directions: storing heat for use at night and on cloudy days, and cooling that runs on renewable energy. Both are in development and are not part of what we sell today; we will update this page when there is something to show.
Questions about NaturaTemp
Short answers about who we are and how a project starts.
Where do you install?
Across Israel. The survey takes place at your site, in any region.
Is a small project worth it for you?
Yes. A 12 m³ pool with three panels is a project we have done; see the projects page.
What happens after the installation?
A 5-year warranty, remote monitoring and support. You see the system on your phone or computer, and if something looks wrong, you contact us.
How do we start?
A short call or a message, then a site survey and a detailed quote. The knowledge hub explains how the system works before you decide.
