Giacomini Hep2o R478 Underfloor Heating Thermal Actuator 230v 2 wire R478V
The actuators of the R478 series are normally open (NA). They allow them hydraulic supply of the circuits when there is no voltage and they have a cable
with two conductor for the connection to room thermostats or adjustment regulators.
The R478M version has a stroke end micro-switch for driving circulators or zone valves.
The R478V version has varistor for installation on places where the network voltage undergoes sudden changes that could damage the electronic
The R478MV version has either varistor or stroke end micro-switch.
In radiant panel heating and cooling systems, the normally open electrical actuators are to be preferred as they are not supplied for most of the time
involving a sensible electric energy saving.
Description In order to allow an optimal control of the room temperature, combining the energy saving with a high comfort, the use of electrical actuators on distribution manifolds, on radiator valves with thermostatic option, or on fancoil valves is advisable.
The series of R478 electrical actuators is characterised by an absolute quiet operation, long lasting lifetime as it has no mechanism subjected to wear and a sufficiently slow closing to prevent from water hammer phenomenon.
The operation mechanism is made of wax bulbs controlled by low consumption electrical PTC (Positive Temperature Coefficient).

This is a well engineered Manifold Pump Mixing Unit manufactured in Italy, offering excellent flow rates, with an adjustable water temperature range from 20° C to 60° C making this perfect answer when commission the underfloor heating system for the first time and need to build up the heat very slowly and avoid cracking on a screed floors.
UFH mixing kit is a distribution unit designed to provide reliable flow temperature control, flexible installation and easy start-up. Available with pre-mounted booster pump.
20m² Komfort Low Profile Underfloor Heating System
Komfort 18 mm Low Profile Underfloor Heating System
The Komfort underfloor heating low profile floor system is the perfect solution for both renovation and new build projects. This Komfort Overlay system can be installed over the existing floor with a low build height of only 18 mm. When using these Komfort underfloor heating panels, the costly need to remove any existing floors is eliminated as the UFH Overlay panels can very simply fit on top of the existing floor.
The Komfort UFH Overlay panel offers the perfect answer for a wood or tile floor finish. The Overlay panel design contributes to an easier installation when using these floor finishes and furthermore, when using with a ceramic floor finish, an outstanding 99 watts /m² can be achieved (this will depend on floor finishes etc..)
The UFH panels can be used on ground and upper floors.
The Komfort UFH 18 mm Overlay panels are DFE (gypsum fibre) made from non flammable Fermacell Gypsum Fibreboard which offers top quality dry flooring elements (DFE), and will integrate with any existing heating system.

While some Overlay panels offer only one option of pipework layout, another benefit of the Komfort Overlay DFE Panel is the practicality of installation as it offers the user a choice of pipework design. In addition to this, a quicker installation can be achieved due to the superior design of the Komfort Overlay panels as the need for return panels is eliminated. This allows the 1200 mm x 600 mm universal panels and Komfort 12 mm 5 Layer PE-RT oxygen barrier pipe to be installed with greater ease, making it one of the most flexible Overlay fixing systems in the market.
