The brief

Zimmerstec sells equipment for metering and regulating heat energy and water. The company behind the brand, ZIMMERSTEC UKRAINE LLC, was registered in Kyiv in April 2018 for wholesale of equipment and manufacture of measuring instruments. Its lead product is the Ultracal 201 ultrasonic heat meter. The range also covered M-Bus controllers, converters and adapters, data collection over wM-Bus, M-Bus and Walk-By, and meter servicing, verification and repair. The site's own description mentioned an in-house laboratory and ten years of experience.

In Ukraine, heat meters are bought by developers, housing associations (OSBB), management companies and apartment owners. They compare accuracy class, verification intervals and data interfaces, and check the local heat supplier's requirements. For this kind of business a website works mainly as a technical reference, with specifications, certificates and an easy way to ask for a quote.

Zimmerstec asked for a site that would present its equipment in three languages and that its managers could run themselves.

What we did

Scope

The Marketing MIX project list covers prototypes and design, a customer feedback flow, quick navigation, a site in three languages, SEO optimisation, expert copy for landing pages, an admin panel for the client's managers, adaptation for different devices, and functional and usability testing. The team included a designer, an SEO specialist, a junior PHP developer and a content manager.

Design

The home page mockup opens with the headline "Heat meters from Zimmerstec". It continues with an Ultracal 201 block with "+" hotspots on the device, four advantages, an About block, numbered lines of work (Manufacturing, Sales, Installation, Dispatching, Verification) and contacts with a map. Separate mockups cover certificates, partners, news, meter dispatching and the Ultracal 201 specifications. The design placed a video in the About block; the archived built site shows that block without one.

The built site

The site ran on WordPress with a custom theme, which gave the client's team an admin panel for everyday edits. The August 2020 capture shows a Rus / Eng / Ukr language switch, a product menu, a "Useful information" section with 14 articles, reference projects in Kyiv residential complexes and in Odesa, a callback form, and a footer credit "Development and promotion" linking to Marketing MIX.

Timeline from the Web Archive

  • March 2019. Publication date in the home page's structured data.
  • August 2020. First capture: WordPress 5.1.6 and the Marketing MIX credit.
  • February 2023. By this capture the client had added a LoRa data-collection section, absent in January 2022.
  • July 2024. New phone numbers in the header.
  • August 2025. Last genuine capture: WordPress 5.1.19, a Google Analytics 4 tag, the same design and credit.

Where it stands today

  • 2020–2025. The yearly Web Archive captures of zimmerstec.com, from 14 August 2020 to 23 August 2025, all show the same structure with our credit. The design stayed in use until at least August 2025.
  • 27 April 2026. The registration record shows a new registration. A .com creation date changes only after a domain has lapsed and been registered again.
  • 14 September 2026. zimmerstec.com serves a static copy of the old home page, still with our credit. Inner pages and the English and Ukrainian versions return 404, and the sitemap lists an Indonesian online-gambling page. We found no sign that Zimmerstec runs this address, so this case does not link to it, and we found no other company website.
  • Company. ZIMMERSTEC UKRAINE LLC (EDRPOU 42038597) is still registered and active in Kyiv; its registry record was last updated on 26 March 2026.
  • Product. Kyiv installer Ekoservis offers turnkey installation of the Ultracal 201 (DN15) for 8,500 UAH, and TVO Group's website has a Zimmerstec page with the meter's specifications.
  • Listings. Directories give three different Kyiv street addresses for the company. Our search found no public customer reviews.

What we would add now

The site served Zimmerstec from 2019 to at least August 2025, and the client kept adding to it. A 2026 version would start here.

Domain and platform continuity

Registrar auto-renewal, renewal monitoring and a documented domain owner, so the brand name stays under the company's control. A move from the WordPress 5.1 branch, still in use in 2025, to a supported stack.

Ukrainian first

Ukrainian as the default language, with Russian and English as alternates and an x-default hreflang. The archived site defaulted to Russian, while Ukrainian-first has been the norm for consumer-facing Ukrainian sites since 2022.

Structured data for AI answers

The archived pages carry only basic WebSite and WebPage markup. Organization and Product markup with the Ultracal 201 specifications, plus FAQPage markup on the buyer articles, would let search engines and AI assistants quote direct answers to questions such as what an ultrasonic heat meter costs.

A reference buyers can use

Downloadable spec sheets and certificates, a page for each buyer type (developer, housing association, apartment owner) and a step-by-step description of installation and verification.

Leads, speed and listings

A quote form per buyer type in place of the single callback form, call tracking and GA4 conversion events. WebP images with lazy loading, one canonical host, and one address across all directories.

Testimonial

Overall, I'm happy with the project. The MMIX team brought our idea to life and built an informative, dynamic website where customers can easily get to know our products and make their choice.
