Home hot-water upgrade planner
Plan your heat-pump hot-water installation before comparing proposals
Start with household demand, the existing hot-water system, placement and site services. Then compare the exact product, installation scope and incentive assumptions proposed for the property.
A request may be sent to up to three eligible suppliers, subject to service-area and supplier availability. Availability and proposal outcomes vary.

Before requesting proposals
Describe the household and existing hot-water system first
These details help a provider assess what still needs an onsite check. They do not establish product suitability or compliance by themselves.
2
Household demand and recovery
Describe occupancy, showers, baths, peak-use periods, unusual demand and whether running out of hot water is already a problem.
3
Property and access
Note gates, stairs, narrow paths, lifting constraints, the existing base, removal route and where equipment or materials could be placed safely.
4
Available records
Gather recent energy bills, product labels, switchboard information, property or strata requirements and any previous plumbing or electrical documents.
Site and service scope
The old system's location is not automatically right for a heat pump
The proposed model, property and local requirements determine the checks. Do not alter electrical, plumbing or refrigerant components yourself.
Placement, airflow and noise
Ask the provider to apply the proposed product requirements to clearances, airflow, weather exposure, service access and likely noise at bedrooms, boundaries and neighbouring property.
Plumbing and drainage
Identify hot and cold water connections, pressure controls, tempering, relief discharge, condensate or drainage paths and any pipework changes included in the scope.
Electrical scope
Ask whether the existing supply, circuit, protection and isolation are suitable, who will complete any electrical work and what completion evidence applies.
Existing-system removal
Confirm disconnection, draining, removal, disposal or recycling, temporary hot-water arrangements and treatment of the old base and pipework.
Recommendation evidence
Ask why this heat pump and scope fit this property
Product and warranty evidence
Request the exact model, capacity, product documentation, operating limits, warranty terms and who is responsible for product and installation claims.
Capacity rationale
Ask the provider to explain how demand, recovery, climate, operating schedule and the selected product informed the recommendation.
Site-specific method
Confirm placement, access, protection of the property, plumbing, drainage, electrical coordination, commissioning and handover.
Provider checks
Identify who will assess and perform each part of the work, then check the credentials, registrations or licences required by the relevant jurisdiction.
Compare the written scope
Make each heat-pump proposal answer the same six questions
A final total is only comparable when the proposed product, installation, removal, incentives, warranties and exclusions are clear.
1
Proposed system
Manufacturer, model, capacity, configuration and any substitutions that require written approval.
2
Base installation
Included labour, delivery, placement, plumbing, drainage, support, commissioning and handover.
3
Electrical work
Included checks and work, exclusions, responsible trade and documentation.
4
Removal and making good
Existing-system disconnection and removal, disposal, temporary arrangements and repair of affected surfaces.
5
Incentive assumptions
Scheme, eligible product, certificate or rebate assumptions, responsible party, paperwork and treatment if eligibility changes.
6
Warranty and exclusions
Product and workmanship responsibilities, service requirements, excluded conditions and change-control process.
Incentive assumptions
Treat rebate eligibility as a check, not a headline discount
Federal certificates and state or territory programs have different product, installation, property and documentation rules. Programs and available funding can change.
Ask the provider to identify the scheme, eligible model, responsible party, paperwork, amount assumed in the proposal and what happens if the claim is rejected or changes.

FAQ
Frequently Asked Questions
Clear answers to the questions homeowners usually ask before comparing quotes.
1 What should a heat-pump hot-water proposal include?
What should a heat-pump hot-water proposal include?
Ask for the proposed product and capacity, placement, plumbing and drainage work, electrical work, removal of the existing system, commissioning, warranty responsibilities, incentive assumptions, exclusions and the process for agreeing scope changes.
2 How should a heat-pump hot-water system be sized?
How should a heat-pump hot-water system be sized?
Sizing should account for household occupancy, hot-water use patterns, fixtures, recovery requirements, climate, available operating periods and the proposed product. Ask the provider to explain the assumptions behind the recommended capacity rather than relying on household size alone.
3 What placement details should be checked?
What placement details should be checked?
Check the manufacturer requirements and proposed clearances, airflow, support, weather exposure, drainage, service access, pipe runs and likely operating noise at bedrooms, boundaries and neighbouring property. Property and local requirements can also affect placement.
4 Who should complete the plumbing and electrical work?
Who should complete the plumbing and electrical work?
Licensing and compliance requirements vary by jurisdiction and by the work involved. Check the relevant state or territory authority, ask who will perform each part of the work, and verify the required credentials and completion documentation before installation.
5 Does every heat-pump water heater qualify for certificates?
Does every heat-pump water heater qualify for certificates?
No. Eligibility under the federal Small-scale Renewable Energy Scheme depends on the system, installation and current scheme requirements. Check the Clean Energy Regulator information and ask the provider to identify the eligible model and certificate assumptions in writing.
6 Are heat-pump hot-water rebates the same across Australia?
Are heat-pump hot-water rebates the same across Australia?
No. Programs can be limited by state, territory, product, property, household, installer, timing and available funding. Check the authority responsible for the property and treat any discount as an assumption until eligibility and documentation are confirmed.
7 Can I compare proposals using the final total alone?
Can I compare proposals using the final total alone?
A final total can hide different products, capacities, site work, electrical scope, removal, incentive assumptions, warranties and exclusions. Compare an itemised written scope and ask how unknown conditions or eligibility changes will be handled.
8 How does The Wombat heat-pump request work?
How does The Wombat heat-pump request work?
Requesting a supplier match is free for homeowners. A request may be sent to up to three eligible suppliers, subject to service-area and supplier availability.
