Water heaters
Apply for product acceptance
This information is for manufacturers, ACPs and other applicants. It details how to apply for water heater acceptance.
Water heaters must meet certain requirements to be accepted onto our public list. This means ACPs can install the product to get energy savings and create certificates.
Technical requirements
All heat pumps must comply with relevant testing, energy efficiency, and safety standards.
Before applying, you must have all required documents and certification. Typically, you submit the following evidence to meet our requirements:
- TRNSYS model and modelling reports (modelled in accordance with AS/NZS 4234:2021)
- AS/NZS 2712 accreditation certificates
- user manuals
- test reports and other product performance evidence, including tanks and collectors (as required)
- pump and controller specifications
- system schematic and bill of materials
- dimensioned tank diagram
- data plate(s) photographs
- application declaration forms.
Before you apply, you need to review the relevant application guide to
- understand the requirements for each calculation method and type of water heater
- understand how to apply for and group multiple products (within one or a number of applications), particularly where you have a large suite of products
See the Relevant documentation section below.
Model numbers, information and values must be consistent across all documentation you provide in your application. Inconsistencies and errors in your application documentation may result in rejection of your application. Inappropriate grouping of multiple products within an application may also result in rejection of your application.
Duplicates cannot be submitted
You cannot apply for duplicate models in TESSA. The system will automatically reject your application.
We do not process products that are already accepted. For example, if your product was already accepted under an earlier version of AS/NZS 4234, we will not accept a new application with different values.
However, if your product requires acceptance across different calculation methods, please contact our team to discuss the next steps.
Please note that there are different requirements and values to submit for HEER and IHEAB calculation methods. These cannot be submitted jointly.
