A technology with a track record - not a promise, not a concept. Documented, certified, and operating across three continents.
From Laboratory to Living Room
It is easy to make claims. It is considerably harder to back them up with independent laboratory results, certified performance data, and over a decade of real-world installations across three continents.
The Lotus Hydrogen Plasma Combi Boiler has done both. This page brings together the technical specifications, independent test results, certification status, and documented installation case studies that form the evidence base behind every claim made on this site.
The Product Range — Specifications at a Glance
E SERIES — FOR APARTMENTS & SMALL SPACES
| Model | Coverage | Input | Output | COP |

V SERIES — FOR DETACHED HOUSES & VILLAS
| Model | Coverage | Application |
|---|---|---|
| V 200 | ~150 m² | Detached house |
| V 300 | ~200 m² | Villa |
| V 500 | ~300 m² | Large villa |
S SERIES — FOR INDUSTRIAL BUILDINGS & LARGE AREAS
| Model | Coverage | Application |
|---|---|---|
| S 400 | ~500 m² | Small commercial |
| S 700 | ~1,000 m² | Campus, hotel |
| S 1000 | ~1,800 m² | Greenhouse, factory |
All models share the same core hydrogen plasma technology and COP performance. The series differ in heating capacity, not in operating principle.

International Case Studies Since 2010
All videos are unedited — real people, real environments, real results. No artificial editing or beautification.
CASE STUDY 1 · TURKEY · MODEL V 200
Villa Heating & Hot Water — Çanakkale
A 4-storey villa in the Mıhlı region, Denizkent coastal site, Çanakkale. The Lotus V 200 was installed to meet the complete heating and hot water needs of the villa. The installation demonstrates the system's suitability for multi-storey residential buildings and its compatibility with existing radiator circuits without modification.
CASE STUDY 2 · GERMANY · MODEL E 300
Villa + Solar Integration — Ehringhausen
One of the most cited Lotus installations in Europe. An E 300 boiler combined with rooftop solar panels in a villa in Ehringhausen, Germany. No fossil fuel is used at any stage — the solar panels provide the electrical input; the boiler converts water into hydrogen plasma. The result: zero carbon emissions, zero fuel cost, closed-loop sustainable heating and hot water.
This installation has been running since the early 2010s and is one of the longest continuously documented hydrogen plasma heating deployments in Europe.
CASE STUDY 3 · TURKEY · MODEL S 700
Student Campus — Central Anatolia (150 Students)
A high school student campus located in a region with harsh winter conditions. The heating and hot water needs of 150 students are met entirely by Lotus S 700 boilers with partial solar energy integration. The installation operates through temperatures well below −10°C — conditions under which air-source heat pumps would fail entirely.
This case study is particularly significant for demonstrating large-scale residential applications and cold-climate reliability across a full heating season.
CASE STUDY 4 · TURKEY · MODEL S 1000
Greenhouse Heating — Solar & Geothermal Integration (1,800 m²)
A single Lotus S 1000 heats 1,800 m² of greenhouse space. Electricity consumption has been significantly reduced by integrating solar, wind and geothermal energy into the system. The greenhouse installation demonstrates the system's suitability for precision temperature environments — where consistent heat delivery is critical for plant growth and where fuel independence removes exposure to energy price volatility.
Export Countries — A Growing Global Footprint
Since 2010, Lotus Hydrogen Plasma Combi Boilers have been exported to and installed in:
Each export market represents independent validation — local installers, local regulatory environments, and local customers who have evaluated the technology and chosen it.
