Why install this hybid Hot-Water system?
☀️ Maximise surplus solar energy – use excess PV to heat water instead of wasting it.
🔋 Reduce battery drain – hot water is produced without pulling from stored battery capacity.
🚿 Instant, reliable hot water – gas automatically boosts temperature when solar is insufficient.
💰 Lower energy costs – prioritises free solar, only uses gas when needed.
⚙️ Automatic, intelligent operation – seamless switching between electric and gas for optimal efficiency.




As accredited LP Gas installers, Deltool also provides complete gas installation, maintenance and repair services. This includes LP Gas systems for cooking, space heating and backup hot water solutions. The hybrid hot water system forms part of a broader, professionally installed gas offering, ensuring safe, compliant installations that integrate seamlessly with your solar and energy management setup.

Disclaimer:
This calculator provides an estimated solar system size based solely on the user’s monthly electricity bill, selected tariff, phase type, and estimated night-time usage. Actual system requirements may vary depending on load profile, appliance types, peak demand, wiring layout, roof orientation, shading, seasonal variation, municipal supply limitations, and other site-specific conditions.
All results are for preliminary guidance only and do not constitute a formal design, engineering analysis, or installation quotation. Deltool recommends an on-site assessment and detailed load study before any purchasing or installation decision is made.
Why install a standby generator?
-
Guaranteed backup when solar falls short – Maintain power during extended bad weather, high seasonal demand, or unexpected battery depletion. ⚡
-
Protect energy security off-grid – A generator acts as your safety net, ensuring critical loads keep running when your solar system needs support. 🔋
-
Reduce overspending on oversized solar and batteries – Use a generator for occasional support instead of investing heavily in extra battery and PV capacity for rare worst-case conditions. 💰
-
Secure productivity and prevent downtime – Keep homes, farms, and businesses operating without disruption when power demand exceeds available solar supply. 🏡🏢
-
Peace of mind for critical loads – Protect essentials like water pumps, refrigeration, security systems, and communications when reliability matters most. 🛡️
