Klarlauf. The plumbing firm that knows what applies right now
Klarlauf is a complete template for master plumbing and heating businesses with an emergency service. 33 pages with eight services, each with its own tool, six fixed prices, six project pages, six guides, process, about and careers. At its heart is a live board that uses the time in Kassel and the public holidays in Hesse to show whether the office is staffed, when an enquiry will be answered and whether the call-out charge is €49 or €89 right now. Add a funding calculator for heat pumps, leak detection to try out and the service area as a pipe network with travel times.

Creator of this template ai-website.com The story
A business that names its price first
Read the full story
Most plumbers' websites show a tap, an emergency number in red and a list of keywords. If you land there in the evening with water under the sink, you learn neither whether anyone is answering right now, nor what the call-out costs, nor when a reply will come.
Klarlauf answers exactly that, for the moment someone asks. A board uses the time in Kassel and the public holidays in Hesse to work out whether the office is staffed and which rate applies. Every service page has its own tool, from the moisture meter for leak detection to the funding calculator for heat pumps.
Behind it stands a whole business with eight services, six fixed prices, project pages with a site diary, guides, careers and an emergency service that names its price first. What is missing are your own photos, hours and prices, and every business adds those with its AI.

Scroll through the homepage
The Klarlauf homepage travels as you scroll. Each stop explains why a section is built the way it is.
- 01
The board "As of now"
Weekday, time and a marker on the week bar, next to them office, reply and call-out charge for exactly this moment. It recalculates every 30 seconds.
- 02
The pipe bend
Two yellow legs from one corner frame the opening headlines and sit offset behind photos. As they appear, the vertical leg grows first, then the horizontal one, and a bright thread runs through.
- 03
The pipe network
The service area as a drawing, every place connected to the warehouse by a right-angled branch. Pick a place and yellow runs through its pipe, with the travel time next to it.
- 04
The rising main
The services overview draws a house with a rising main. Eight services hang off it as branches, and as it appears, yellow rises once from bottom to top.
- 05
The moisture reading
A slider moves a moisture meter along the drawn wall, the reading rises towards the leak, and the sentence below says where the wall will be opened.
- 06
The funding calculator
Floor area, year of construction and two bonuses give heat load, funding rate and grant, under the funding rules as of October 2026 and capped at 70 percent.
Not one page. All of them
You are not buying a homepage full of promises, you are buying a complete website. Every subpage is fully designed and written.

The centrepiece
A board that works by the clock
Anyone who arrives with a dripping pipe does not ask about opening hours, but whether someone is answering right now and what the call-out costs. The board works out both from the time in Kassel and the public holidays in Hesse, right in the browser.
- Office, reply, call-out
The contact page shows the weekday, the time and a marker on the week bar. Next to them it says whether the office is staffed, whether an enquiry will still be answered today and whether the call-out is €49 or €89 right now.
- Public holidays included
Good Friday, Whit Monday, Corpus Christi and the other public holidays in Hesse are calculated by the page itself. On a public holiday the higher rate applies, and the board names the next working day on which the reply will come.
- One clock everywhere
The emergency page puts the time and the rate next to the number, the home page and the footer show the office status. Your AI enters your hours and prices, and the knowledge files name every place.

Who Klarlauf is built for
A template gets good by making choices. Klarlauf is tailored to one niche, and honest about where it does not fit.
Built for
- Master plumbing and heating businesses with repairs, bathroom renovation, heat pumps and a round-the-clock emergency service
- Plumbers with fixed prices for small jobs and a service area of around 30 minutes
- Agencies that deliver sites for building services trades repeatedly and predictably
Not meant for
- Air conditioning and ventilation contractors with split systems, Luvhagen from the same category fits them
- Electrical contractors with meter cabinets, wallboxes and solar PV, Kupferrode fits them
- Bathroom showrooms and businesses with several branches, the site knows one warehouse and one service area

At home on the phone
More than half of all visitors arrive on a phone, in emergencies almost all of them. Klarlauf is built for that, not squeezed into it.
Mobile first. Layout, spacing and tap targets are made for thumbs.
Fast on weak networks. Statically built, free of heavy scripts and plugins.
From ZIP to live website
Three steps. You need Node.js, an editor and one hour.
More than a pretty surface
Klarlauf ships with its knowledge and the seven skills, so your AI understands the website instead of guessing it apart.

Quick answers
It reads the time in Kassel, whatever time zone the visitor is in, and calculates the ten public holidays in Hesse itself, the movable ones from Easter Sunday. Office status, reply time and call-out charge follow from that. There is no server and no third-party service behind it, everything runs in the browser.
Yes. The office hours live in src/data/site.ts, the public holidays in src/scripts/zeit.ts. Cut-off times and rate boundaries are typed into the scripts of the contact and emergency pages, and the knowledge files name every place. For another federal state your AI swaps the list of public holidays.
As soon as you enter them. The fixed prices live in src/data/site.ts, the price tables of the services in src/data/leistungDetails.ts. The funding calculator works with rules of thumb in its own page, the call-out charges sit in texts and scripts. Your AI enters your values in one go.
It reflects the state of October 2026 and is marked with that date on the page. From February 2027 the speed bonus for replacing old heating drops every six months, which the note below the prices says. Before going live the current values belong in there, and the copywriting skill explains what to watch for when advertising with funding.
Without heat pumps, yes. Heating is one service of eight, and your AI can remove it. The emergency service goes deeper, its number appears in the header, menu, footer, closing band and schema. The template-setup skill describes this change across around fifteen files.
No. Company, names, prices, projects, key figures and testimonials are invented and marked as examples on the page. There is deliberately no rating score, not in the structured data either. Both phone numbers come from a block that the German Federal Network Agency keeps free for media use.
As placeholder pages with instructions, not as finished texts. The legal notice lists the mandatory details of a plumbing and heating business and the image credits, the privacy page describes what the website does technically. We deliberately do not supply legal texts, because they differ for every business.
No. Font and photos live in the project, map and pipe network are original drawings, and there are no tracking pixels and no videos. Consent is prepared in case you add an analytics service later.
Yes. Every heading, every text and every key figure is there without a script. The live board then shows the office hours and both rates, and the tools show a finished starting state.
The English version addresses visitors as you throughout, in a plain and factual tone, including form messages and the consent dialog. Your AI adjusts the tone in one pass if your business speaks differently.
Anywhere that serves static files. Astro builds the site into a folder of finished HTML that runs without a database or server script. The two forms check the input and send nothing yet, they need a recipient before going live.
Yes. Pay once, yours forever, for your own projects and client projects. You get the complete source code without a watermark.
The photos come from Pexels and may be used commercially. They show no real business, no real staff and no real sites, though. Your own photos belong in the team and project sections, and LIZENZEN.md explains what applies.
Yes. In the English package the whole website is in English, with English knowledge files and English skills.
No. You tell your AI in the project folder what should change, and it finds the place through CLAUDE.md and the seven skills. If you want to work by hand, the content sits in a few data files under src/data.
