Engineering Hot Water & Energy Systems for buildings where performance matters. Luxury residential · Hospitality · Healthcare · Commercial · Industrial.
Great buildings should perform as well as they look.
Every year, millions are invested constructing beautiful homes, hotels and commercial buildings. Yet the systems people rely on daily often perform far below expectations. We believe exceptional buildings deserve exceptional engineering.
Eliminating wait times for hot water and maintaining consistent pressure at every fixture, every floor.
Ensuring an uninterrupted supply of hot water for all users — storage engineered around actual demand.
Reducing unnecessary generator reliance. Your generator should be for emergencies — not for showers.
Maximising the ROI and output of solar energy investments — every system engineered as one.
EngiTech doesn't simply offer five services. We practise one discipline: Performance Engineering™ — designed to optimise every system that determines how a property actually performs for the people who occupy it.
Consistent water pressure throughout the building — stable, powerful, hotel-quality performance for every user.
Hot water capacity matched to actual demand — no rationing, no scheduling mornings around the geyser.
Hot water where it is needed, when it is needed — in under 10 seconds at every fixture.
Energy Independence™ — integration with renewable energy, battery storage and backup systems. Comfort with or without ZESA.
Every system is designed to accommodate future growth — upgrades without demolition.
A premium user experience across every application — residential, hospitality, healthcare or commercial.
Reliable operation for decades — not months. Engineered, commissioned, maintained and verified in writing.
We don't engineer products. We engineer performance.

Pressure-balanced hot water delivering stable temperatures and consistent pressure across residential, hospitality and commercial applications. Flagship product family — four engineered systems, one powerful outcome.
Engineered hot water storage from 100L to over 1,000L — designed around actual demand, occupancy and usage profiles, not standard tank catalogues. Buildings don't use hot water. People do.
Smartly engineered solar, battery and backup power solutions designed around the way buildings operate. Essential™, Plus™ and Elite™.
Advanced recirculation technology — hot water in under 10 seconds at every fixture while eliminating water waste. Integrates seamlessly into new builds, renovations and retrofits.
Swim in comfort, every month of the year. High-efficiency commercial and residential pool heating — advanced inverter technology, near-silent operation and smart solar integration.
Four engineered systems. Every one delivers the same powerful hotel-pressure experience. The differences relate to performance during outages, weather, and future expansion.
Inverter-friendly. Runs on surplus daytime solar. Complete solution for homes with existing solar PV and battery storage. Five stars in every ZESA scenario.
Wired to your inverter — an outage never stops it collecting heat. The strongest solar contribution in the range. Upgradeable to a heat pump at any point.
Heats your water today with a clear, no-waste path to a full heat pump upgrade whenever you're ready. Affordable entry with expansion built in.
Lowest cost, simplest system in the range. Nothing to service. One honest limitation: no upgrade path — upgrading beyond it requires replacing the complete unit.
*Roof Mounted pricing is a build-up estimate, not yet a locked EngiTech trade quote. Final pricing confirmed at assessment. All prices are starting prices at 150L.
Whether you're building new, buying your first solar system, improving an existing installation, or replacing one that never met expectations — EngiTech provides complete engineering support.
Complete design and installation — Solar PV, hybrid inverters, battery storage, backup power integration, commissioning.
Professional assessment of existing installations — solar performance, battery condition, inverter operation, electrical safety, optimisation recommendations. One of EngiTech's highest-value consulting services.
Additional panels, battery expansion, inverter upgrades, generator integration, heat pump integration and EV readiness.
Three grades — Essential™, Plus™ and Elite™ — at 5kVA, 6kVA, 8kVA and 10kVA. The engineer confirms the correct size; the grade sets the quality and resilience of the components.
The foundation level — hot water and essential loads running without ZESA.
Extended independence — more reliable components and longer outage coverage.
Full building energy independence — the highest-spec components, double the storage.
All figures are supplier cost-basis estimates, not yet locked EngiTech retail quotes. Higher-capacity configurations (6kVA–10kVA) available — confirmed at assessment. Warranties vary by grade: typically 12–24 months inverter, 24–60 months battery, 20 years panels.
When ZESA disappears, how long can a building continue operating normally? Modelled on a common premium residential scenario: six-person household, 200L storage, existing solar PV, hybrid inverter, battery storage — generator OFF. That's when engineering matters most — after two or three cloudy days without reliable ZESA.

Engineered ResilienceOur systems maintain high functionality even during power outages — not as a backup feature, but as the primary design objective.
Verified PerformanceReliability backed by rigorous performance modelling of integrated heat pump and solar systems.
Operational ContinuityProven ability to sustain critical thermal functions independently of grid stability.
Every situation has a specific problem. Every problem has a specific free assessment designed around it. Any suburb in Zimbabwe. No gate on decision authority.
26.8% of Harare's international arrivals are from the UK, where hot water arrives in under 5 seconds. A 0.5-star rating drop from shower complaints suppresses future bookings by 15–25%. The review is written at the airport — before you know there's a problem.
The decisions available while walls are open cost a fraction of what they cost after the plasterer leaves. A return loop through an open ceiling — post-plaster retrofit requires opening finished walls at a multiple of the renovation-stage cost. This is not a sales technique. The window is physical.
Hot water decisions are being made on your build right now, by default, by contractors who have never spoken to each other. Your solar contractor and your hot water contractor are designing two independent systems. You are building once.
Assessment conducted remotely. No return trip required. A local contact attends the site visit. You join findings by video. The written report arrives in your inbox within 48 hours. Read it in Birmingham. Act from anywhere.
Inverter-compatible heated water across every unit — specified once, replicated consistently. No roof tanks. Maintained rooflines. A differentiator no Harare development currently advertises with engineering backing.
The fittings you specified need 1.0 bar minimum dynamic pressure. A Harare gravity supply delivers 0.3–0.5 bar. No tanks on the roof means rooflines stay exactly as drawn. The gap closes at design stage — before construction fixes it permanently.
The technology changes by application. The discipline doesn't — every project is measured against the Seven Performance Standards™.
Premium homes, estates and renovations — our founding market and deepest source of engineering experience.
Residential estates, apartment developments and mixed-use projects — specified once, replicated consistently across every unit.
Hotels, lodges, resorts and Airbnb developments where guest experience and operating cost both depend on the same engineering.
Hospitals, clinics, laboratories and healthcare facilities requiring dependable hot water systems — clinical reliability, engineered.
Boarding schools, universities and student accommodation — consistent availability over a longer operating day.
Office developments, wellness centres, gyms and commercial facilities — optimising workspace productivity and energy efficiency.
Mining accommodation, processing facilities, workshops and industrial plants — robust infrastructure for heavy-duty environments.
Strategic planning and end-to-end project management — every system a performance differentiator for the development.

"Performance Is Engineered."
"We went from waiting over a minute for hot water to getting it in under 10 seconds — every bathroom, every morning. I didn't realise how much it was affecting the routine until it was fixed."
"International guests stopped mentioning the shower in their reviews. Our rating recovered within two months. We haven't run the generator for water heating since installation."
"We use the pool in July now. International guests who book in winter mention the heated pool in their five-star reviews. It's the reason some of them rebook."
EngiTech is a specialist engineering company that designs, installs, commissions and maintains integrated water and energy systems for buildings where comfort, reliability and operational performance are critical.
Rather than supplying individual products, we engineer complete systems that combine hot water, water pressure, thermal storage, renewable energy, backup power and pool heating into one coordinated solution.
