Three audiences, one brand, no confusion
ZET is an HVAC specialist based in Diepenbeek with more than 45 years of experience in installation and maintenance. The company sells and installs air conditioning, heating, plumbing and ventilation systems for renovations and new construction. It serves homeowners, DIY enthusiasts and professionals. Self-installers can find complete kits in the online store at zet-shop.be and get specialist advice in the Diepenbeek showroom.
Each audience arrives with a different question. The site needed to direct everyone to the right destination within two clicks: a service, the online store or a quote.
“Someone looking for a heat pump is not necessarily looking for self-installation instructions, and vice versa.”
A clear path for every service and audience
Technology helps people choose. It doesn’t try to take center stage.
The site runs on SvelteKit with Storyblok as its CMS and ships as a static website on Vercel.
- 01
Find the right service quickly
Air conditioning, heating, plumbing, ventilation, installation and maintenance each get their own page, written for the right audience.
- 02
A dedicated path for self-installers
The self-installation pages link straight to the online store at zet-shop.be. Visitors know right away where to go.
- 03
Share incentive updates quickly
The ZET team publishes news, promotions and incentive information in Storyblok on its own. That matters in a market that changes monthly.

An HVAC website that moves with the market
Light technical foundation
Static pages deployed with SvelteKit and Vercel. Best mobile PageSpeed score: 94 in September 2026, though other measurements that month were much lower.
A page for every service
The zet.be main menu leads to separate pages for air conditioning, heat pumps, heating, plumbing and ventilation, plus a self-installation path and a link to the online store.
Projects and incentives, self-published
The ZET team publishes its own projects and incentive news. Examples: an air-to-air heat pump in Diepenbeek and a homepage teaser on the 2026 heat pump incentives.
Measurements are the next layer
PageSpeed tracks speed, Search Console tracks reach in Google. We follow both every month.
