Heat Pump Hot Water Installation Site Requirements
A heat pump hot water installation needs open space for airflow, a level base with drainage and a suitable power supply. The site also needs a position that keeps noise away from bedrooms and neighbours, plus clear access for delivery and servicing.
Below, we explain each site requirement and how to tell if your current hot water spot can be reused. We also cover what happens on installation day and what to send with a quote request.
What are the site requirements for a heat pump hot water installation?
Most Melbourne homes meet the site requirements for a heat pump hot water installation, with only minor changes required. Before work starts, we check that your site has:
Enough space and airflow around the unit
A firm, level base
Drainage for condensate and relief valve water
Access to existing water lines for plumbing connections
A power supply that suits the system
A position away from bedrooms and neighbouring homes to limit noise
A clear path for delivery and room for future servicing
Space, ventilation and manufacturer clearances
An integrated heat pump draws heat from the surrounding air, so it needs open space around it. Enclosed cupboards and narrow recesses can restrict this airflow and affect how well the system heats water.
Each manufacturer sets minimum clearances for its units in the installation manual. These distances vary by model, so we check them against the system you choose.
Where space is limited, a split system may suit. For instance, Reclaim heat pump and Rheem heat pump split models let the tank sit indoors while the compressor sits outside, either mounted on a wall or placed on the ground.
Base, drainage and plumbing
The unit needs a firm, level base, such as a concrete slab, that can carry the weight of a full tank. The site also needs a drainage point for condensate and a temperature and pressure relief valve. We always ensure we include a new base into all of our quotes when required.
Electrical supply and switchboard
Most systems plug into a standard 10A power point. Some need an isolator or a dedicated circuit, and older switchboards may need room for a new breaker. We handle this electrical work, and a licensed electrician issues a Certificate of Electrical Safety.
Noise, bedroom windows and neighbouring properties
Victorian law sets prohibited times for residential heat pump noise. During these times, the unit must not be heard inside a habitable room of another home. On weekdays, this applies before 7 am and after 10 pm. On weekends and public holidays, it applies before 9 am and after 10 pm. Placing the unit away from bedroom windows and side fences helps, and timer settings let it run during the day.
Access for delivery and servicing
Installers need a clear path from the street, so gates, side passages and steps all matter. The unit also needs space around it so a technician can reach the panels and valves later.
What photos and details should you include with your quote request?
Photos and a few property details help us check your site before we visit. Please include:
The current hot water unit and its compliance plate
A wide shot of the proposed installation spot
Your switchboard
The access path from the street to the spot
Your suburb and the number of people in your home
Any rebates you plan to claim
Can you reuse your existing hot water location?
Most outdoor spots used by gas or electric storage systems can be reused. An integrated heat pump, such as an Aquatech heat pump, iStore heat pump or Hydrotherm heat pump, may suit these spots. For indoor or enclosed locations, consider a split system.
