Alternatives · Comparison
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.

The Real Line
Before you compare a spec sheet, see the source. Hitze runs its own extrusion, brass-machining and packing lines and ships a fully-branded PEX, multilayer and underfloor-heating range from stock. (Some frames are captioned placeholders where product photography is being finalized.)
Who & Why
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.
You want a second German-brand source so you’re not single-sourced — at a MOQ that doesn’t tie up your working capital.
You’ll only switch to an alternative that is genuinely equivalent in material, standard and certification — and that pairs with a manifold that fits.
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.

Objective Comparison
A straight, factual side-by-side. Rehau® is an established PEX and underfloor-heating brand; the cells below describe Rehau in generic, accurate terms and describe Hitze specifically. Where a Hitze figure is still being confirmed, we say so rather than guess.
| Criterion | Hitze | Rehau® |
|---|---|---|
| Brand origin | German brand, engineered in Germany by our German engineering team | Established German-heritage PEX & underfloor-heating brand |
| PEX pipe | PEX (PEX-a / PEX-b), to EN ISO 15875 / ASTM F876 direction | Established PEX product line |
| Multilayer | 5-layer multilayer PEX-AL-PEX, oxygen-tight aluminium core, EN ISO 21003 direction | Multilayer / composite pipe offering |
| Underfloor heating | PE-RT UFH pipe, EVOH oxygen barrier per DIN 4726, 16 / 20mm, matched manifolds | Established underfloor-heating systems |
| Key certification | DVGW certified; cUPC / NSF-14 / NSF/ANSI 61 / WRAS / CE+DoP direction | Holds recognized industry certifications |
| MOQ | Low, sample-friendly (exact figure available on request) | Refer to the brand for their terms |
| Private label / ODM | Yes — open to private label under your brand | Refer to the brand for their terms |
| System scope | Pipe + manifold + press / compression / push-fit / brass fittings, one supplier | Full systems offering |
| B2B terms | Flexible, sample-friendly for wholesalers, contractors & brands | Refer to the brand for their terms |
Comparison is on public, factual grounds only — material class, certification families, system scope and B2B terms. The Rehau column is described in generic, accurate terms; we make no claims about their MOQ, pricing or internal conditions. Full material and dimensional data, plus certificate and listing numbers, are available on request in the comparison pack.

Why 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.
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 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.
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.
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.
Pipe, manifolds and fittings (press / compression / push-fit / brass) coordinated to fit — you sell a system, not a parts list.
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.
Honest transparency: Hitze is engineered in Germany and manufactured to German standards in our audited facilities, and every line is DVGW / cUPC / NSF / WRAS-directed with verifiable listings. We lead with certification you can check, not origin claims.

Underfloor Heating
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.
