What VacuSol does
VacuSol, spol. s r.o. is a privately held Czech manufacturer and installer of solar thermal systems, founded in 1994 by Luboš Vařejka in Dolní Rožínka, Vysočina region. The company designs, produces, and installs the VS 10 T vacuum tube solar collector based on the heat pipe principle, alongside packaged solar water heating sets sized for 1-3 person, 4-person, 5+ person households, apartment buildings, and commercial facilities, plus add-on modules for supplementary space heating and pool heating. Manufacturing is performed in-house at the Dolní Rožínka facility, with components including stainless steel frames, tempered glass vacuum tubes, copper absorbers with selective solar absorber coating, and copper heat exchangers.
The company's revenue model combines hardware sales (collector systems and pre-configured packages priced from CZK 70,000 for a 1-3 person residential set with subsidy, up to CZK 105,000 for a 4-person set, with custom pricing for larger systems), professional installation and commissioning services, full subsidy-application assistance under the Nová zelená úsporám program, and warranty/post-warranty service that also covers competitor systems. Customer segments include single-family homeowners, multi-family apartment buildings, commercial laundries and guesthouses, and seasonal cottage/chalet owners. Distribution is direct-to-customer across the Czech Republic, supplemented by an in-house partner program and commercial export partnerships into seven European markets (Austria, Hungary, Slovakia, Italy, Bulgaria, Poland, Germany).
VacuSol is a bootstrapped, family-controlled enterprise (founder Luboš Vařejka and his son Lukáš), holding fewer than 10 employees as last disclosed in a 2014 radio interview, and operating without external funding or institutional investors. The company holds EN ISO 9001:2001, EN ISO 14001:2005, and EN 12975-2 thermal efficiency certifications. Customer references span hundreds of installations since 1994, including multi-family projects of up to 40 collectors delivering 31.98 kW of thermal output. The business model is exposed to a near-term policy shift: the company's own website (2025/2026 content) anticipates the Nová zelená úsporám subsidy largely ending in 2026 in favor of interest-free loans, a material demand-side variable for solar thermal in the Czech Republic.
