Stiebel Eltron Open Vented Mixer Taps for SNU Water Heaters

Stiebel Eltron mixer taps are purpose-built for use with Stiebel Eltron SNU-series open-vented under-sink storage water heaters. Unlike standard mixer taps, these open vented designs allow the tap spout to act as a pressure relief vent for the water heater — a critical safety function that means they must only be used with a compatible Stiebel Eltron SNU system and must never have aerators, flow straighteners (other than Stiebel Eltron approved accessories), or water filters attached to the spout.

At PlumbingSales.com.au, we stock three Stiebel Eltron mixer tap styles to suit different models and aesthetics. Browse our range and order online 24/7 with fast delivery Australia-wide.

Our Stiebel Eltron Mixer Tap Range

MES Single Lever Sink Mixer (232389)
The classic entry point to the Stiebel Eltron open vented tap range. The MES features a standard swivel spout design with single lever control and is compatible with the SNE 5, SNU 5 and SNU 10 compact storage water heaters. Available in chrome, it suits a wide range of kitchen and laundry decors and carries a 3-star WELS rating at a maximum flow rate of 8L/min.

Design-Kollektion Goose Neck Mixer Taps (207883–207886)
The premium Design-Kollektion gooseneck range features a 160mm reach curved spout with side lever control — delivering ample clearance over kitchen and laundry sinks with a sleek contemporary silhouette. Designed exclusively for the Stiebel Eltron SNU Plus open-vented storage water heater. Available in four finishes: Chrome, Matte Black, Brushed Gold and Brushed Nickel. WELS 6-star rated at 4.5L/min.

Design-Kollektion Fixed Outlet Mixer Taps (207887–207890)
A compact, minimalist alternative to the gooseneck, the Design-Kollektion fixed outlet features a straight fixed spout with single lever control — a clean aesthetic ideal for smaller sinks or modern, pared-back interiors. Also designed exclusively for the SNU Plus and available in the same four finishes: Chrome, Matte Black, Brushed Gold and Brushed Nickel. WELS 6-star rated at 4.5L/min.

Choosing the Right Stiebel Eltron Mixer Tap

The single most important selection factor is matching your tap to your water heater model.

For SNU 5, SNU 10 or SNE 5 water heaters:
The MES single lever sink mixer (232389) is the correct compatible tap for these models.

For SNU Plus water heaters:
Choose from the Design-Kollektion Goose Neck or Fixed Outlet range (207883–207890). The SNU Plus is a newer generation heater and requires these dedicated taps — the MES is not compatible.

Once you've confirmed heater compatibility, choose between the gooseneck and fixed outlet spout styles based on your sink clearance and aesthetic preference. The 160mm reach gooseneck suits deeper sinks and offers more manoeuvring room, while the fixed outlet suits compact spaces or minimalist interiors.

Important installation note: These are open vented taps. Do not attach aerators, water filters, or non-approved flow straighteners to the spout — the unrestricted spout is essential to the safe venting function of the water heater. All Stiebel Eltron mixer taps must be installed by a licensed plumber in accordance with AS/NZS 3500 and local plumbing regulations.

Frequently Asked Questions

Can I use a standard mixer tap with my Stiebel Eltron SNU water heater?
No. Stiebel Eltron SNU-series water heaters are open-vented systems that require a specifically designed open vented tap. Using a standard pressurised tap will prevent the system from venting correctly and can cause damage or safety issues. Always use a compatible Stiebel Eltron open vented mixer tap.

Which Stiebel Eltron mixer tap suits the SNU Plus?
The Design-Kollektion Goose Neck (207883–207886) and Design-Kollektion Fixed Outlet (207887–207890) taps are designed exclusively for the Stiebel Eltron SNU Plus. The MES (232389) is not compatible with the SNU Plus.

Can I fit an aerator or water filter to a Stiebel Eltron open vented tap?
No. The open spout on these taps serves as the pressure vent for the water heater. Adding any restriction — including aerators, water filters, or non-approved flow straighteners — interferes with this venting function. Only Stiebel Eltron approved accessories should be used.

What's the difference between the gooseneck and fixed outlet Design-Kollektion taps?
Both are designed for the SNU Plus and are available in the same four finishes with the same 6-star WELS rating. The gooseneck features a 160mm reach curved spout with more clearance over the sink; the fixed outlet has a straight, compact spout suited to smaller sinks or minimalist spaces.

Are these taps available in finishes other than chrome?
The Design-Kollektion range is available in four finishes — Chrome, Matte Black, Brushed Gold and Brushed Nickel. The MES single lever mixer is available in chrome only.

Do these taps need to be installed by a licensed plumber?
Yes. All Stiebel Eltron open vented mixer taps must be installed by a licensed plumber in accordance with the Plumbing Code of Australia, AS/NZS 3500, and relevant local regulations.
