Bulk Hot Water Systems
At Energy On, our focus is smart cost recovery, maintenance and asset management for bulk hot water, also known as centralised or circulating hot water.
Bulk hot water is a centralised system that heats water (usually via gas or electricity) and circulates it to every apartment or lot. We install and use privately owned hot water meters to individual meter each lot so consumption is measured per dwelling, and invoices can be generated accurately.
Energy On is your Centralised Hot Water Specialist
Energy On is a recognised expert in Circulating Hot Water (CHW) systems, with decades of experience designing, metering and billing CHW arrangements across residential, mixed use and commercial developments throughout Australia.
We work with developers, Owners Corporations, Body Corporates and Strata Managers to ensure CHW systems are configured for accurate measurement, fair cost recovery and long term efficiency. Our team understands every component of the CHW model, from centralised plant design and meter selection through to individual occupier billing, regulatory compliance and ongoing customer service. We manage the full end to end process, removing the administrative burden. Whether the system is powered by gas, electric heat pump or solar assisted technology, Energy On delivers the metering, billing and account management that turns a shared utility into a fully recovered cost. With a national footprint, established systems and a deep understanding of embedded network and submetering regulation, Energy On is the partner of choice for any development relying on Circulating Hot Water.
Centralised Gas Hot Water
Many apartment buildings and multi-tenant developments are built with Circulating Hot Water (CHW) systems to supply hot water to all residential premises. CHW is the method of centrally heating water and distributing it to occupiers across a multi-tenant environment from a single source. A large, centralised gas hot water plant (commonly referred to as a "boiler") is installed with the capacity to service every premises in the building. Heated water is then circulated through the building and delivered to each occupier on demand. To measure individual consumption, a dedicated hot water meter is installed for each premises, recording the volume of hot water used, typically in kilolitres (kL). This allows each occupier to be billed accurately for their own usage rather than sharing the total cost across the building.
Centralised Electric (Heat Pump) Hot Water
Many more modern apartment buildings and multi-tenant developments are built with a centralised electric heat pump/s to service every premises in the building. Heat pumps work by extracting ambient heat from the surrounding air and using it to heat the water, making them significantly more energy efficient than traditional gas boilers and producing lower greenhouse gas emissions. The heated water is then circulated through the building and delivered to each occupier on demand. To measure individual consumption, a dedicated hot water meter is installed for each premises, recording the volume of hot water used, typically in kilolitres (kL). This allows each occupier to be billed accurately for their own usage rather than sharing the total cost across the building.
A bulk hot water system with private metering is beneficial for:
- Developers & Builders
Simplified design, lower construction costs, and more saleable floor space by removing individual hot water units from each dwelling. - Owners Corporations & Body Corporates
Reduced running costs, accurate billing, cost recovery, and reduce wastage from unmetered shared use. - Occupiers/Tenants
Reliable hot water on demand, no maintenance or replacement costs, and transparent billing on actual measured consumption. - The Environment
High-efficiency systems typically produce substantially less green-house gases.
