Set contents
Everything you need — calculated per m².
Every set follows the same rule, so you know exactly what arrives on the pallet. The calculator above shows the quantities for your area.
Every m² comes with 10 m of water pipe — 75 m² means 750 m.
Adhesive for bonding the ThermoSlim panels — 75 m² needs 90 kg.
The manifold is sized to your area. Above 100 m² the set contains two.
Flush or surface-mounted metal cabinet holding 4 to 12 circuits.
10 heating circuits means 20 union nuts in the set.
Two cabinets means four ball valves.
A Euro pallet carries up to 1,000 kg — 120 m² means at least two pallets.
Transport from Germany
Why transport is not in the price.
The panels are made in Germany and arrive on a Euro pallet. Fuel prices change week to week and no freight company issues a quote valid for more than 24 hours. That is why we set the transport cost only when you confirm the purchase — based on your postal code and the pallet weight.

Frequently asked
Before you choose your area.
Is the price on the page final?
No — it is an indicative calculation for the area you selected. The final quote follows the on-site measurement, and transport from Germany is set when you confirm the purchase.
Why is transport not included?
Because fuel prices keep rising and falling, and freight companies issue quotes valid for at most 24 hours. A transport price that is right today cannot be guaranteed tomorrow — so we calculate it once you confirm the purchase.
Why do you ask for the postal code?
The postal code gives us the route and the cost of shipping the pallet from Germany to you. Without it we cannot price transport, so it is required in every enquiry.
What if I have more than 100 m²?
One manifold takes at most 12 circuits, which covers up to 100 m². Above that the set contains two manifolds and two cabinets — e.g. 105 m² is assembled as 50 + 55 m². From 101 m² the price per m² is €73.13 instead of €81.25.
What if I have more than 200 m²?
For projects above 200 m² we do not price on the page. In the calculator choose “More than 200 m²”, enter the exact area and your postal code — we prepare an individual quote.
How much does the delivery weigh?
Count on 10 kg per m². A 75 m² set weighs about 750 kg and fits on one Euro pallet; above 1,000 kg it ships on at least two. The calculator shows the weight and number of pallets for every area.
Can I really install it myself?
Yes — ThermoSlim is a dry system without screed. You bond the panels with the special adhesive, press the pipe into the grooves and connect it to the manifold. Sets of 55 m² and above include technical support; we recommend leaving the connection to the heat source to a professional.
What if I want your installation after all?
Choose “With our installation” in the calculator — the set is the same, and installation is charged at €12.50 per m² up to 100 m² and €11.25 per m² above that.
Do the prices include VAT?
All prices on the page include 25 % VAT, with the net amount shown alongside. Every price also carries its anchor price — for ThermoSlim DIY that is the price on the day the offer was introduced, 22/09/2026. The full price list and machine-readable files are on the Price list page.
