Custom calculators for your website
Interactive tools that show your customers how much energy your heat pump water heaters use, what they cost to run against the electric or gas system being replaced, and what that adds up to over the life of the unit. Built around your product range, styled to your brand, and running on the same AS/NZS 4234 modelling we use for scheme submissions and MEPS work. Where rebates apply, the calculator prices those too.
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.
Annual energy consumption
Household size and climate zone both change the answer, so the calculator uses the customer's own. The figures come from AS/NZS 4234 modelling rather than a nameplate COP, and they are the same ones behind a scheme submission.
Running cost against electric and gas
Your unit's annual running cost beside the cost of the system it replaces, at the customer's own electricity and gas rates. The same calculation works in Australia and New Zealand.
Lifetime cost comparison
Your unit against electric storage and gas over fifteen years, with the crossover point marked. Customers adjust their own energy rates and expected price rises.
Product specification comparison
Your range side by side: rated capacity and power input, refrigerant, delivery temperature, sound level, warranty and price. A customer can compare two models without opening two datasheets.
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 straight from your scheme registrations.
Recommendation questionnaire
Six questions about the home: size, occupants, climate, usage, installation space and budget. The visitor gets a product recommendation and the reasoning behind it. You get their email address and every answer they gave.
Commercial ranges
The same tools for commercial heat pump water heaters, including VEEC and ESC value across every model you have registered under the VEU and ESS.
Your own comparison
Describe the comparison you want and we will build it, with the working available if anyone asks: solar diversion, controlled-load and time-of-use tariffs, annual emissions, payback against a named competitor. We own the engine, so there is no fixed feature list.
Try it
Below is an example of a working calculator. Change the postcode, the household size and the system being replaced, switch between Australia and New Zealand, then change 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.

About the demonstration. Every figure shown in the demonstration is illustrative: capacities, power inputs, COPs, sound levels, prices, energy use, running costs and certificate values alike. The products are invented and do not represent any system on the market. What is real is the method: the 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.
Product illustrations courtesy of EECA, Hot water heat pumps in the home. These are placeholders for the demonstration: your build uses your own product photography or renders, one per model, and we can work from whatever you already have for your brochures.
Turning visitors into enquiries
Six questions about the home, then the email address, then the recommendation. The order is deliberate. Someone will hand over an address while they still want the answer, and far less often once they already have it.
They get a specific model, how much hot water it delivers for their household, and why their answers point to that one. You get a named lead with all six answers attached, so whoever picks up the phone already knows what the call is about.
Question 1 of 7
How many bedrooms?
How it's delivered
Two options, and you pick one. Most brands embed it; the hosted page suits anyone whose website is slow to change or locked down by an agency.
Option 1: 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.
Option 2: 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
Energy prices move, and every running-cost and payback figure moves with them. In Australia there is a second layer on top: STCs step down every January, VEU and ESS methods change, certificate prices move daily and 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 tariff and incentive data live from our own platform API rather than from a hardcoded table, and we handle scheme method changes at our end. Your customers see today's numbers.
New Zealand ranges
A New Zealand build runs the full energy and cost engine: annual consumption by household size and climate zone, running cost against the electric cylinder or gas system being replaced, lifetime cost with the crossover point marked, and the range comparison. It uses the New Zealand climate zones defined in AS/NZS 4234, the same standard the Australian schemes are built on.
There is no STC, VEEC or ESC equivalent here, so a New Zealand calculator has no rebate panel. The running-cost comparison carries the argument on its own. 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, the Australian scheme registrations and the New Zealand compliance work. The figures in your calculator come from the same engine that produced your test and submission documentation, and we can show how every one of them was derived if a customer, an installer or a regulator asks.
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.
