✍️ Gas vs. iHot Solar Hot Water: Upgrading to Electric Storage

Gas hot water was once the gold standard for quick heating, but today's energy landscape has changed the math. High daily network connection fees and surging fuel prices mean sticking with gas is increasingly costly.

Upgrading to a standard electric storage tank paired with an iHot smart solar controller turns your hot water system into a low-cost, sun-powered thermal battery.

The Problem with Gas Hot Water

Double Charges: You pay twice—first for the gas consumed, and second for daily connection fees just to keep the service active.

Low Solar ROI: Without an electric hot water link, excess rooftop solar power gets exported to the grid for minimal feed-in tariffs while you pay full price for heating fuel.

Fossil Fuel Volatility: Gas rates remain prone to sharp market price swings.

How the iHot + Electric Storage Combination Works

Instead of replacing gas with complex, expensive alternative hardware, this setup combines simple, proven components:

A Standard Electric Tank: A basic resistive-element electric tank is affordable, durable, and low-maintenance.

The iHot The solid-state iHot unit has dedicated PV solar generation and redirects power straight to the electric tank's heatingelement.

Thermal Storage: Heat is stored in the insulated tank as hot water, delivering free, clean energy long after the sun goes down.

Making the Switch

Replacing a gas system with an iHot inverter and a standard electric tank eliminates daily gas supply charges, maximizes rooftop solar usage, and provides a reliable, cost-effective hot water upgrade.

✍️ Solar Incentives available when you Upgrade your Hot Water with iHot

Replacing an expensive, energy-guzzling hot water setup doesn't have to break the bank. Thanks to Australia’s Small-scale Renewable Energy Scheme (SRES) , homeowners can access government incentives when upgrading to a direct solar PV water heating solution powered by the iHot Smart Inverter .

Rather than relying on complex thermal plumbing, iHot connects a dedicated array of solar PV panels directly to your existing hot water storage tank. Because iHot is a Clean Energy Council (CEC) approved inverter compliant with Australian Standards, your installation qualifies for government energy programs and incentives.

Save up to $950 with the STC credits

Under the SRES scheme, qualifying solar energy installations earn Small-scale Technology Certificates (STCs) . These certificates carry real dollar value and are applied directly as an upfront point-of-sale discount on your system:

Upfront Discount: Your accredited installer calculates and handles the STCs for you, deducting the certificate value directly from your installation invoice.

Maximum Solar ROI: You receive government support on the dedicated rooftop PV panels and inverter while keeping your existing ground-mounted tank.

Ongoing Energy Savings: Once installed, iHot operates at up to 99% MPPT efficiency, delivering up to $900 in annual bill savings by heating your water straight from the sun.

Act Before SRES Deeming Periods Phase Down

The federal SRES program runs until December 31, 2030 . However, the deeming period (and the total value of STCs generated per system) reduces every year.

Installing an iHot solar hot water system sooner locks in a higher upfront incentive value, making it easier than ever to achieve energy independence.

✍️ Off-Grid Hot Water Made Simple

iHot Solar Hot Water Inverter

Heating water is often the single biggest battery drain on an off-grid property. Standard electric tanks pull massive surges of AC power, forcing you to over-spec your battery bank and main inverter just to take a shower.

The iHot Smart Solar Hot Water Inverter solves this problem by taking water heating completely off your primary off-grid system.

Why iHot is a Game-Changer for Off-Grid Living

Instead of pulling power from your main off-grid battery bank, iHot connects a small array of dedicated solar PV panels straight into your existing hot water element .

It turns direct sunlight straight into thermal energy, storing heat in your water tank rather than cycling your battery setup.

Zero Battery Strain: Your main off-grid battery bank stays fully charged for lights, refrigeration, and power tools.

No Heavy Roof Loads or Pipes: Unlike old-school solar thermal systems, there are no heavy water tanks on your roof, no pumps to freeze, and no glycol fluids to flush.

Up to 99% MPPT Efficiency: iHot continuously extracts every available watt from your dedicated solar panels—even on overcast days—to heat your tank directly.

Retrofits Existing Tanks: Connects to standard electric storage water heaters (elements up to 3,600W) without changing the tank or thermostat.

Generator/AC Backup Compatible: On extended rainy days, manually or automatically top up hot water via your backup generator without risking cold showers.

Thermal Battery Power, Pure and Simple

Treat your hot water tank like a giant thermal battery. With iHot, you get reliable, high-efficiency hot water without multiplying your battery costs or over-stressing your off-grid inverter and battery systems.

✍️ Meet iHot

Traditional solar hot water systems have long been a staple of Australian homes, but they come with undeniable drawbacks. Heavy, water-filled panels strain roof structures, complex plumbing loops require ongoing maintenance, and extreme weather can cause freezing or boiling issues.

The iHot Solar Hot Water Inverter offers a modern alternative. Rather than acting as a standard grid diverter or relying on old-school thermal plumbing, iHot connects a set of solar PV panels directly into your existing electric storage hot water tank. It turns standard sunlight directly into thermal heat, simply, safely, and cost-effectively.

What is iHot?

iHot is a compact, high-efficiency solar water heating inverter designed to use a small dedicated solar panel array for use with any existing storage hot water system.

Instead of routing power through your main household inverter, iHot takes DC power (up to 350VDC) directly from a dedicated array of solar PV panels and uses advanced Maximum Power Point Tracking (MPPT) technology to feed that energy into your standard heating element.

It requires no modification to your tank’s existing element or thermostat , making it an easy retrofit upgrade for standard electric storage tanks.

How iHot Outperforms Traditional Solar Thermal

For decades, solar hot water meant mounting a massive hot water tank and heavy copper collectors directly onto your roof. iHot replaces that heavy infrastructure with lightweight PV panels and standard electrical cables.

Key Benefits of the iHot System

1. Ultra-High Efficiency (Up to 99% MPPT)

Solar panels generate varying amounts of power depending on sunlight. iHot uses an MPPT controller with up to 99% efficiency. This ensures every single watt generated by your panels even on overcast days is extracted and squeezed directly into your hot water element.

2. Automatic Grid Backup & Off-Grid Ready

While iHot prioritises 100% free solar energy during the day, it also features integrated grid backup functionality. If heavy overcast weather persists, the system can draw from grid power overnight or during off-peak periods, ensuring your household never runs out of hot water. It is also completely compatible with off-grid properties.

3. Massive Bill Savings

Water heating makes up roughly 20% to 30% of a typical household’s energy bill. By generating your hot water directly from dedicated solar panels, a typical family can save up to $900 per year on electricity costs.

4. Simple, Lightweight Installation

Because iHot sits quietly next to your ground-mounted hot water tank and wires up like a standard electrical component, installation is quick and hassle-free. You don't need complex plumbing modifications or roof re-enforcements.

Upgrade Your Water Heating with iHot

Whether you're looking to cut your monthly power bills, lower your grid dependency, or replace a failing thermal solar setup, or a noisy Heat Pump the iHot inverter offers a smarter, lighter way to heat water.
