HST® - hybrid stone technology

artificial stone + hybrid heating element
ecological material + thermal performance

Hydronic copper circuit

The internal hydronic element is made of thin copper pipes, treated with a specific anticorrosion and anti-expansion process, for a high performance and perfect reliability.

The reduced internal pipe’s volume decreases significantly the amount of circulating water. The occasional noise
of air bubbles present in normal radiators are
therefore absent.

Tested at 8 bar (with a service pressure of 6 bar), they guarantee maximum uniformity of heat and, at the same time, an excellent strength of the circuit.

Etch-foils heating elements

The flexible sheet heating elements are
produced using etched-foil technology on a
screen-printed circuit.

This heating element emits an homogeneous heat that minimizes any phenomenon of anomalous expansion. It manages the energy with maximum effectiveness and has a minimal thickness.

Stone body

A perfect carrier for heat accumulation from
the two heating sources, the artif icial stone
body of the HST® system uses an innovative
mixture of marble powder and a special acrylic resin. 

It allows a high accumulation of heat inside, but also, given its large surface area and its high conductivity, a gradual transfer of heat to the environment by radiation.

Advantages of HST® technology

» High comfort in the area covered by the radiant system
» No air changes and no dust movement
» Maximum operating silence
» Maximum energy savings thanks to the use, at steady state, of low temperature water
» Maximum flexibility for eventual technical renovations
» Maximum freedom to place objects or furnishings for maximum display freedom
» Possibility to verify and intervene in case of failure without invasive works
» No need to work on floors
» Low thermal inertia of the environment
» Reduction of risk of superficial and interstitial condensation of the wall
» Reduction of thermal transmittance to the wall

Traditional radiator

» heat transfer only by convection
» high temperature stratif ication in every
» waste of energy
» presence of mold due to moisture
condensation on cold internal walls.
» circulation of dusts
» less comfort

Floor heating

» heat transfer by radiation
» high vertical temperature stratification
» expensive installation and maintenance
» high time to reach the thermal regime
» can not be used as a heat pump


» heat transfer by radiation
» stratification reduced to a minimum
» fast and easy installation and maintenance
» rapid heat distribution
» usable in every season
» reduced energy consumption
» greater comfort
