Custom calculators for your website
Interactive tools that show your customers exactly what your heat pump water heaters will cost them, save them and earn them in rebates. Built around your product range, styled to your brand, and running on the same modelling and live incentive data we use for scheme submissions.
What these calculators can show
Most brands start with one or two of these and add more later. Everything below runs off the same engine, so combining them costs less than building them separately.
Rebates across your whole range
Every model priced against the customer's own postcode — STCs nationally, VEECs in Victoria, ESCs in New South Wales, plus state rebates where they stack. Certificate counts come from your registrations, not an estimate.
Lifetime cost comparison
Your unit against electric storage, gas and a competing heat pump over fifteen years, with the crossover point marked. Customers adjust their own energy rate and expected price rises.
Annual energy consumption
Household-size and climate-zone aware, from AS/NZS 4234 modelling rather than a nameplate COP. The same figures that stand behind a scheme submission.
Product specification comparison
Your range side by side — capacity, refrigerant, delivery temperature, warranty, price and net cost after rebates. One table that answers "which one do I need?".
Recommendation questionnaire
A short set of questions about the home — size, occupants, climate, usage, installation space, budget — ending in a specific product recommendation and a captured lead.
Commercial ranges too
The same tools for commercial heat pump water heaters: VEEC and ESC value across every model you have registered under the VEU and ESS.
Try it
This is a working calculator, not a screenshot. Change the postcode, the household size and the system being replaced, then switch the layout and colours to see how differently the same tool can be presented.
Preview a different build
Same engine, same numbers. Every build is laid out and styled to the brand, so no two look alike.

Turning visitors into enquiries
A calculator answers a question. A questionnaire starts a conversation. This version asks about the home, then recommends a specific model and captures the enquiry with the answers attached, so your team knows what the lead is about before they pick up the phone.

Embedded in your site
One line of code drops the calculator into a page you already have. Works with Shopify, WordPress, Webflow, Squarespace and anything else that lets you paste an embed.
Hosted by us
We run it at your own address, calculator.yourbrand.com, and you link to it. Nothing to install and nothing for your web team to maintain.
It stays current
STCs step down every January. VEU and ESS methods change. Certificate prices move daily. Product registrations lapse. A calculator built once and left alone starts quoting the wrong numbers within a year, and your customers find out before you do.
Ours read incentive data live from our own platform API rather than a table hardcoded on build day, and scheme method changes are handled on our side. The numbers your customers see are the numbers in force today.
New Zealand ranges
New Zealand has no equivalent of the STC, VEEC or ESC schemes, so there is no rebate layer to show. Everything else works the same way: annual energy, lifetime cost against electric and gas, and product comparison, using the Auckland and Dunedin climate zones that AS/NZS 4234 defines for New Zealand. Switch the demo above to New Zealand to see it.
Why the numbers hold up
We are the people who do the AS/NZS 4234 modelling and the scheme registrations. The figures in your calculator come from the same engine that produced your submission, not from a marketing approximation, and we can document how every one of them was derived if a customer, an installer or a regulator ever asks.
About the demonstration. Example products with illustrative figures. These do not represent any system on the market. Certificate and energy figures are derived through the same AS/NZS 4234 and scheme formulas a real job uses, from assumed performance data. Your build uses your own certified product data. The commercial tab is different: it reads the live VEU and ESS registers, so those brands, models and certificate values are real.
Want one for your range?
Tell us what your range looks like and what you want the tool to show. We will scope it and come back with a fixed quote. Every build is different, so we price them individually rather than off a list.
