Mermerni radijatori
Mermerni radijatori from Niš sells and installs electric radiators made of natural stone. The company did not have a website before, and customers usually ask the same things: how many radiators a room needs, how much electricity they use and how they are installed. The site had to answer those questions before the first call, without prices and without promises the company had not yet confirmed.

Answers before the first call
Mermerni radijatori has a 13-page website: models and dimensions, how the radiators work, accessories and thermostats, marble and granite, calculator and consumption, a comparison of electric heating, warranty, delivery and installation, a gallery, FAQs and a separate page for Niš. Each page answers one question customers ask over the phone, so the conversation starts with the choice, not with explanations.
Prices are not published, because they depend on the model, the number of units and installation. The warranty and delivery are described the way the company offers them: terms come with the quote, delivery covers Niš and the surrounding area, and other places by arrangement. A room thermostat is an optional extra.

Power and consumption calculator
On the calculator page, the visitor enters the room's floor area, with a slider or a number, and selects the insulation, the ceiling height and whether it is a room, a bathroom or an attic. The result updates instantly: the required power rounded to 100 W, a suggested model or number of radiators with a link to that model in the table, and electricity use per day and per month in kWh.
For a space that needs more than four radiators, the calculator does not offer a ready-made layout; instead, it says that placement along the walls is suggested after an inquiry. Without JavaScript, the page shows a table of examples.

Illustrations, labeled as such
To begin with, the company had no photos of its own installations, so the radiators shown in rooms on the site are illustrations, and the gallery is labeled that way. When the company sends real photos, they will replace the illustrations.
The structured data describes the company with its phone number and service area in Niš. The address and opening hours are not included, because the company has not confirmed them yet.
04 / 05
Phone instead of a form
The company arranges its work by phone, so the site has no form. The number is in the header of every page, and on a phone there is a bar at the bottom with buttons to call and to open the calculator. The form is prepared and will come back once the company has an email address for inquiries.

Static site, checked before publishing
Astro builds finished HTML for all 13 pages, so the server does not run any code for the visitor. All the JavaScript on the site is about 6 KB compressed, images are generated from the originals in AVIF and WebP, fonts are served from the same server, and the site has no cookies or analytics. Security rules allow scripts only from the same domain, with no scripts written inline in the page.
Before publishing, a script checks the entire output: internal links and anchors, alt text on every image, a single main heading and heading order, a unique page title and description, the canonical URL, structured data, the sitemap, the security rules and any leftover test content. Mobile PageSpeed was 100 on November 12, 2026.
On a phone
The same site, in your hand.
Most visitors come from phones, so the layout, buttons and images are arranged for the small screen first.
Questions
What clients ask.
Does the site show radiator prices?
No. The price depends on the model, the number of units and installation, so it is given over the phone. The site helps customers know, before they call, how much power and how many radiators they need.
How does the calculator work out the required power?
It starts from the floor area and the power per square meter for the selected insulation, then adds extra for a higher ceiling, a bathroom or an attic. It rounds the result to 100 W and suggests a model or a number of radiators.
Are the images on the site photos of real installations?
No. They are illustrations and are labeled as such. Real photos will go on the site when the company sends them.
Why is there no inquiry form on the site?
The company arranges its work by phone. The form is ready and will come back once the company has an email address for inquiries.
