The Rheem Gas Continuous Flow Range
Rheem invented the continuous flow category in Australia, and the range remains the benchmark for reliable, efficient instant gas hot water. Mounted on the wall and heating water only when you need it, a Rheem continuous flow unit delivers endless hot water while taking up far less space than a storage tank.
The domestic range spans four sizes — 12L, 16L, 20L and 26L — each available in 50°C and 60°C models, in natural gas or LPG. Every model is 6-star efficient with Rheem Q Factor™ for rapid, stable hot water and Flamesafe® overheat protection.

FAQs
Rheem Gas Continuous Flow — Frequently Asked Questions
What is the Rheem gas continuous flow range?
It's Rheem's range of gas continuous flow (instantaneous) hot water systems — 12L, 16L, 20L and 26L models that heat water on demand as it flows through the unit. With no storage tank you get endless hot water, 6-star efficiency and Rheem Q Factor™ temperature stability.
What sizes and models does it come in?
Four sizes — 12L, 16L, 20L and 26L (litres per minute at a 25°C rise) — each available in a 50°C factory-preset model (876A series) and a 60°C model (874A series), in natural gas or LPG.
What's the difference between the 50°C and 60°C models?
The 50°C models are factory preset to deliver 50°C, so no separate tempering valve is required for domestic use (complying with AS3498). The 60°C models deliver a higher temperature where required. We'll recommend the correct model for your installation.
What size Rheem continuous flow do I need?
As a guide (moderate climate): the 12L suits 1 bathroom, 16L suits around 1–1.5, 20L around 1.5–2, and the 26L around 2–2.5 bathrooms. For large homes, two units can be linked with Rheem EZ Link® for up to 56 L/min. We'll size the right model for your home.
