A German-Engineered Alternative to Rehau®

Looking for a second German-brand PEX and underfloor-heating source — with a MOQ you can actually start on and a private-label option? Hitze is engineered in Germany, built to German DIN / DVGW standards, and covers the same core lines: PEX, 5-layer multilayer (PEX-AL-PEX) and PE-RT underfloor heating — pipe, manifolds and fittings as one system.

Rehau® is an established PEX and underfloor-heating brand, and if you’re here you already value German-engineered piping. Hitze gives you that same value from an independent German brand — DVGW certified, and open to terms the big brands rarely offer: low MOQ, sample-friendly trials and private label. Supplied to wholesalers, contractors and private-label brands across North America and Europe.

Trade only — Hitze supplies wholesalers, contractors, distributors and importers, not end-consumers.

Who & Why

Who Looks for a Rehau® Alternative — and Why They Choose Hitze

People searching for a Rehau alternative almost never want a downgrade — they want the same German-engineered value on better terms. Three buyers come to this page.

Wholesalers & Distributors

You want a second German-brand source so you’re not single-sourced — at a MOQ that doesn’t tie up your working capital.

Radiant & Plumbing Contractors

You’ll only switch to an alternative that is genuinely equivalent in material, standard and certification — and that pairs with a manifold that fits.

Private-Label Brands & Importers

You want to sell a German-engineered radiant and plumbing range under your own label, at a MOQ you can launch a market with — something the biggest German brands rarely offer.

Hitze is built for all three: an independent German brand, DVGW certified, covering PEX, multilayer and PE-RT underfloor heating, with low MOQ, private label and a complete matching system. Switching supplier shouldn’t mean switching away from German engineering — with Hitze, it doesn’t.

Why Hitze

Why Buyers Move to Hitze

Switching away from Rehau® only makes sense if you keep the thing you were paying for — German engineering — and gain terms you couldn’t get before. That’s the Hitze proposition.

Still German

Hitze is a German brand, engineered in Germany by our German engineering team and built to German DIN / DVGW standards. You don’t trade down on engineering to switch.

DVGW — the Hardest German Proof

DVGW is the German water and gas authority certification, and it’s the single strongest evidence of German-standard piping. Hitze holds it — certificate number available on request.

The Full Material Range

PEX (PEX-a / PEX-b), 5-layer multilayer PEX-AL-PEX with an oxygen-tight aluminium core, and PE-RT underfloor heating with an EVOH oxygen barrier per DIN 4726 — the same core lines you rely on today.

Low MOQ + Private Label

Start on a MOQ that doesn’t tie up your capital, and put your own label on a German-engineered range — terms the biggest brands rarely offer. MOQ figures available on request.

One System, One Supplier

Pipe, manifolds and fittings (press / compression / push-fit / brass) coordinated to fit — you sell a system, not a parts list.

Built for Two Markets

North American potable direction (cUPC / NSF-14 / NSF/ANSI 61) and European approvals (DVGW / WRAS / CE+DoP) from one certified range — the paperwork your target market already asks for.

Underfloor Heating

Underfloor Heating: Pipe, Manifold and Fittings That Match

Most people looking for a Rehau® alternative are running — or selling — hydronic underfloor heating, and there the system matters more than the single pipe. Hitze supplies the whole water side.

Hitze supplies PE-RT underfloor-heating pipe with an EVOH oxygen barrier per DIN 4726 (so the boiler, pump and manifold are protected from oxidation corrosion), in 16mm and 20mm, dimensioned to pair cleanly with Hitze brass and stainless-steel underfloor-heating manifolds and the matching fittings.

For a wholesaler that means a coherent shelf. For a contractor it means loops, flow-setters and connections that actually fit each other. For a private-label brand it means you sell a complete German-engineered radiant-floor package under your label — not a bag of mismatched parts.

  • PE-RT pipe, EVOH oxygen barrier per DIN 4726, 16 / 20mm
  • Matched brass & stainless underfloor-heating manifolds
  • Coordinated press / compression / push-fit fittings — one supplier

FAQ

Rehau® Alternative — Buyer FAQ

Is Hitze a genuine alternative to Rehau®, or a downgrade?
For the WholesalerIt’s a genuine German-brand alternative. Rehau® is an established PEX and underfloor-heating brand; Hitze is an independent German brand, engineered in Germany, built to German DIN / DVGW standards and DVGW certified. You get the same core lines — PEX, multilayer and PE-RT underfloor heating — at a lower MOQ so you’re not single-sourced.
Do the underfloor-heating pipe and manifold match, like a full system?
For the ContractorYes. Hitze PE-RT underfloor-heating pipe carries an EVOH oxygen barrier per DIN 4726 in 16mm and 20mm, matched to Hitze brass and stainless-steel manifolds and coordinated fittings. You get loops, flow-setters and connections that fit each other from one supplier — a complete hydronic system, not a single component. Specs available on request.
Is Hitze actually German-engineered, and can I prove it to an inspector?
For the Contractor / Spec BuyerHitze is a German brand, designed by our German engineering team and built to German DIN / DVGW standards. The hardest proof is DVGW certification — the German water and gas authority listing — backed by cUPC / NSF-14 / NSF/ANSI 61 / WRAS direction for market listing. Certificate and listing numbers are provided on request.
Can I private-label Hitze where a big German brand won’t?
For the Importer / Private-Label BrandYes. Hitze supplies PEX, multilayer PEX-AL-PEX and PE-RT underfloor-heating pipe under your own label, matched to manifolds and fittings so you sell a complete German-engineered system. MOQ is low and sample-friendly so you can test a market before scaling; exact MOQ and certificate numbers are confirmed per program.
