Individual per-unit systems or one shared plant for the whole block — we help landlords and property managers choose the right configuration.
Written by the March Technology Technical Team · Last Updated: July 2026 · 5 min read
There are two common approaches for apartment blocks: an individual heat pump per unit, where each tenant's electricity bill reflects their own hot water use, or one centralized shared system serving the whole block, managed and billed by the landlord or body corporate. Each has trade-offs around upfront cost, ongoing billing complexity, and available space.
Retrofitting into an existing building is usually straightforward provided there's a suitable spot for the outdoor unit — a balcony, rooftop or utility area with adequate airflow. For single-household sizing guidance, see our residential heat pumps page; for the underlying water heater technology, see heat pump water heaters.

It depends on your priorities — individual units simplify tenant billing but cost more upfront in total, while a shared system is often more cost-efficient overall but requires an agreed billing or cost-sharing approach.
In most cases yes, provided there's a suitable location for the outdoor unit with adequate airflow — we assess this during the free site survey.
Common locations include balconies, rooftops, or a dedicated utility area, chosen to balance airflow, noise and access for servicing.
This is typically agreed between the landlord or body corporate and our team via a maintenance contract, keeping servicing consistent across the whole building.
