Overview

Naturkraftheizung GmbH is an Austrian provider of renewable heating and energy systems headquartered at Solarstrasse 1 in Jenbach, Tyrol. The company presents itself as a specialist in 'simple, clean heating' and bundles heat pumps, photovoltaics, solar thermal collectors and battery storage into integrated home energy concepts. Its website markets the Naturkraftheizung brand alongside the SIKO name, describing SIKO as a Tyrolean manufacturer of solar collectors and heating solutions. According to the company's own account, it has been planning and developing energy solutions for natural heating since 1980 and builds solar collectors at its Tyrol site, which it describes as Austria's oldest solar company. The product range covers several complementary areas. For heating, Naturkraftheizung promotes heat pumps, specifically describing a Tyrolean heat pump from Heliotherm. For electricity, it offers photovoltaic systems that let customers produce their own power and reduce operating costs. Battery and PV storage systems are offered to increase independence, and can be combined with either a new or an existing PV installation. Solar thermal systems use the sun's heat to warm underfloor heating and domestic hot water. The company positions these components as an optimally coordinated overall heating concept that reduces dependence on energy price increases and energy carriers. Naturkraftheizung serves customers primarily in Austria, with a strong regional focus on Tyrol. It operates an 'Energie-Erlebniswelt' (energy experience world) at the SIKO site in Jenbach, where it holds a weekly consultation day every Thursday from 8:00 to 16:30 by prior appointment. The company emphasizes personal advice and a full-service approach covering manufacturing, planning and installation. Its team page lists staff responsible for order processing, consulting for heating and photovoltaic projects, production, installation and service, technical planning, and finance, indicating an integrated in-house capability from consultation through to after-sales service. The company draws on what it describes as over 40 years of experience, tracing its origins to a founding in 1980 when heat pumps and solar were already the focus of the business. Initially solar panels were purchased from suppliers, but within the first years the company developed its own solar collector. This history underpins its current positioning as an established, quality- and durability-focused provider of natural heating solutions in the Tyrolean market.

History

Naturkraftheizung GmbH traces its roots to a company founded in 1980, when heat pumps and solar energy were already the focus of its business. In the early years, solar panels were purchased from external suppliers, but within the first years of operation the company developed its first in-house solar collector. This marked the beginning of its own manufacturing activity in Tyrol. According to the company's own account, it has been planning and developing energy solutions for natural heating since 1980 and builds solar collectors at its site in Tyrol. It describes itself as Austria's oldest solar company, a claim based on this long continuous history in the solar sector. Over the decades, the business expanded from solar thermal and heat pumps into a broader portfolio of renewable home energy technologies. The Naturkraftheizung brand now presents an integrated concept combining heat pumps, photovoltaics, solar thermal systems and battery storage. The company markets a Tyrolean heat pump from Heliotherm as part of its heating offer, and promotes photovoltaic systems and battery storage as ways for customers to generate their own electricity and increase independence from energy price increases. The company operates from Solarstrasse 1 in Jenbach, Tyrol, where it maintains an 'Energie-Erlebniswelt' (energy experience world) and holds a weekly consultation day every Thursday. Its team combines consulting, technical planning, production, installation and service, and finance functions, reflecting a full-service approach. The company emphasizes reliability, quality and durability, stating that it knows what customers expect from its products and strives to exceed those expectations in manufacturing, planning and installation.
