Box Hill Hot Water — What We Install
Box Hill's housing is diverse — from older established homes in Box Hill South to medium-density apartments and townhouses closer to the centre. Hot water demand varies significantly across these property types, and the right system for a two-storey townhouse is often very different from what a 1970s brick home on a quarter-acre needs.
We work across all configurations: gas continuous flow (instantaneous), gas storage, electric storage, and heat pump. Most installs in Box Hill are gas — the suburb has good mains gas coverage and gas systems deliver strong performance year-round regardless of temperature.
About Thermann Hot Water Systems
The unit in the photo is a Thermann continuous flow (instantaneous) hot water system — a compact wall-mount unit supplied through Reece Plumbing. Thermann is Reece's own brand and offers trade-grade performance at a competitive price point. The units are manufactured to the same standards as other major Australian brands and carry a full manufacturer warranty.
Thermann continuous flow units come in a range of flow rates — from 16L/min for standard households up to 26L/min for high-demand applications. Like all continuous flow systems, they heat water only when a tap is opened, so there's no tank to maintain and no standing heat loss. The compact footprint is ideal for Box Hill townhouses where external wall space is limited.
We're brand-agnostic — we recommend the unit that best fits your installation, household size, and budget. We regularly install Rinnai, Rheem, Thermann, Bosch, and Dux. Ask us for a recommendation and we'll give you an honest answer.

Continuous Flow vs Storage in a Box Hill Context
For Box Hill townhouses and apartments with two or more bathrooms, continuous flow is almost always the better choice. The reasons come down to space and performance: a continuous flow unit takes up a fraction of the wall space, there's no hot water to "run out of," and modern units allow precise temperature control.
For larger Box Hill homes — the 4-bedroom houses in Box Hill South or Mont Albert North — a high-capacity storage system (250L+) or a large continuous flow unit (26L/min) handles simultaneous high-demand situations like multiple showers well. We assess the actual household demand before making a recommendation.
