A heat pump has a compressor and a fan as well as a tank, so care is about airflow and the valves.
- Keep the air inlet and outlet clear of leaves, boxes and anything that blocks airflow.
- Have the temperature-pressure relief valve checked periodically, as with any tank.
- If it trips to backup heating or gets noisy, call us — it is usually the fan, airflow or a sensor.
How it works
From first call to hot water back on
The same four steps apply whether you are replacing a failed unit or planning an upgrade.
Tell us what is happening
Call or order online with your suburb and the system you have now. Photos of the unit and its data plate help a great deal.
We scope and quote
We confirm the model, the installation and any extras the site needs, then come back to you before anything is booked.
We supply and install
We bring the unit, disconnect the old system, install and commission the new one, and check the valves are working as they should.
We clear the site
The old unit is taken away where you have asked us to, the work is tested in front of you, and you get the paperwork and warranty details.

Common questions
Rinnai Enviroflo 250L Heat Pump Hot Water System questions
A heat pump moves heat from the surrounding air into the tank instead of using electricity to heat the water directly, so it uses a fraction of the power of a conventional electric tank — even when there is no sun.
Heat pumps cut hot-water running costs substantially against a conventional electric system; the exact saving depends on your usage, tariff and climate. We are happy to talk through a realistic figure for your home.
Yes — supply and installation are handled as one job by our licensed team, and installation is included in the price shown. We confirm the position, airflow and electrical connection when we scope the job.
A heat pump needs airflow around the unit, so it sits outside or in a well-ventilated spot. We confirm the best position at your property so it runs efficiently and quietly.
Heat pumps are sized by tank volume and recovery. Tell us your household size and usage and we will confirm whether this capacity suits before you order.
This Rinnai carries a 5-year cylinder warranty. We confirm the exact terms in writing before you order and handle any warranty claim on a system we installed.
