Specifications
The Heart Technical Data
Designed, machined, and assembled in Denmark. Each unit is individually quality-inspected before shipping.
Benefits
Why Choose The Heart
Zero Electricity
The Heart operates purely on your existing water pressure. No power cord, no batteries, no control panel — just fluid dynamics doing what nature intended.
Zero Maintenance
No filter cartridges to replace, no salt to refill, no chemicals to add, no moving parts to wear out. Install it and forget it — forever.
Whole-House Coverage
The ¾″ DN20 model serves the main water supply for most European homes. Every tap, shower, and appliance receives structured water — not just a single outlet.
Golden Ratio Geometry
Every internal dimension follows the Golden Ratio (φ ≈ 1.618). The egg-shaped chamber initiates a natural, self-organizing vortex — the same geometry found in nautilus shells and spiral galaxies.
Surgical-Grade Materials
316L stainless steel is the same material used in surgical instruments, food processing, and marine drinking water systems. No plastics, no coatings, no chemical leaching.
Eco-Conscious Manufacturing
Additive manufacturing (SLM) produces near-zero waste compared to subtractive machining. Each Heart is built layer by layer — only the metal that belongs in the final part is used.
Applications
How Customers Use The Heart
Whole-House Main Supply
Install the ¾″ (DN20) or 1″ (DN25) Heart on your main water line. Every tap, shower, washing machine, and dishwasher in the house receives revitalised water — no point-of-use devices needed.
Under-Sink / Point of Use
The ½″ (DN15) model fits under a kitchen sink or on a dedicated outlet — ideal for apartments, older buildings with ½″ piping, or post-RO revitalisation of drinking water.
Post-RO Revitalisation
Reverse osmosis produces clean but 'empty' permeate. Install The Heart after your RO system to reintroduce natural water structure before drinking or distribution.
Agriculture & Greenhouses
The 1″ (DN25) model serves large properties, market gardens, and commercial greenhouses. Users report improved plant vitality and reduced water consumption with structured irrigation water.
Installation
How to Install Your The Heart
The Heart installs like any in-line plumbing fitting. A licensed plumber can complete the installation in under 30 minutes. No electrical work, no bypass valves, no special tools required.
- 1 Choose Your Location
Install on the main cold-water supply line after the stopcock and before any branches. The Heart works in any orientation — horizontal, vertical, or angled. - 2 Prepare the Pipe
Cut the pipe and fit standard BSP (or NPT) threaded connectors. Use PTFE tape or liquid thread sealant on the male threads for a watertight seal. - 3 Screw In The Heart
Thread The Heart into place using standard plumbing wrenches. The 316L body has flat wrench grips machined into both ends for easy tightening. - 4 Turn On Water & Check
Open the stopcock slowly and check for leaks at both connections. Tighten a quarter-turn if needed. That's it — the Heart is now working with every drop that flows through.
Perfect Pairing
The Heart + CLEAR Plus RO Membranes
For the ultimate water system, pair The Heart with an Aquaporin Inside® CLEAR Plus reverse osmosis membrane. RO removes contaminants; The Heart restores natural structure. Together they deliver the purest, most vital water possible.
