Como-floor
Como-pex cross-linked polyethylene pipe with oxygen barrier, designed for underfloor heating. The pipe is characterised by its exceptional flexibility and mainly by the fact that it covers and exceeds the temperature requirements of the specific. Furthermore the barrier protects the metal components of the installation (e.g. boiler) extending their lifespan.
Pipe decoiler
To assist the heating-plumbing technician Interplast can provide a special pipe decoiler to hold long lengths (600m) of pipes. It is lightweight for ease of transportation to outdoor areas and is coated with electrostatic paint.
Manifold
A bar type manifold of nickel-plated brass, nominal diameter 1" with 3/4" threading (Eurocone). The flow manifold bears Allen bolts or a flow meter for regulation of circuit flow, while the return manifold includes thermoelectric actuator valves enabling the fitting of thermoelectric actuators which receive commands from the thermostats of each space and enable independent operation of the respective circuits of each space.
In order to achieve optimum balance of the heating system, we propose special inflow and return couplings with attached thermometers.
The success of an underfloor heating installation is based on the smallest possible difference between feed water temperature and return water temperature.
Distribution panel
Made of galvanised steel, 1mm in width. It is adjusted to a height of up to 815 mm. It bears an adjustable removable frame for protection from the plaster, which sets the panel depth from 115 to 165mm.
Thermoelectric actuator
The thermoelectric actuator is connected via a transformer/distributor with the respective thermostat of each space thus enabling different temperature settings for each space. The thermoelectric actuators are connected to the thermostats of each space by means of the transformer/distributor.
24 or 230 Volt bases
24 or 230 Volt bases are controlled by the thermostats and give commands to the thermoelectric actuators on the manifold to open and close the circuits depending on the desired temperature in each space.
Circulator activator
This starts or stops the circulator with the required time delay when the thermostats give start and stop heating commands to the thermoelectric actuators.
Thermostat
A discreet and elegant wired thermostat to achieve the area's desired temperature, which can be adjusted gradually to a ? degree Celsius accuracy.
Panel
Castellated panel made of expanded polystyrene with vapour barrier (PE film) and 30 kg/m3 heat insulation density, dimensions 135x75x4.5 cm, with interlocking edges for perfect fit.
Special joint section
This is placed at predetermined points, selected during our study, and on the lower cases of the building's internal doors so that they can accommodate the thermal concrete's contractions and expansions.
Perimeter wall insulation
This is made of polyethylene foam with film (placed on the castellated panels for proofing against concrete) and an adhesive strip for fixing.
Clip rails
These are used for fixing the pipe to the panel, when required.
Polypropylene fibres
Improves the thermal concrete mix, increasing strength, watertightness and plasticity. This results in easier pumping and pouring.
Polypropylene fibres
These reinforce the concrete and protect against cracking while increasing tensile and compressive strength, resulting in improved strength of the thermal concrete and mitigating problems related to temperature changes.
Three and four-way mix valve
This achieves regulation of feed water temperature, on the basis of the thermal requirements for operation of the underfloor heating system.
Valve electromotor with temperature preset function
This is installed on the three-way mix valve where, with the aid of a sensor, the desired feed water temperature is fixed (15-70oC). We are also able to adjust the time intervals (recommended time: 30 sec) at which the sensor commands the electromotor to balance the feed water temperature.
Contact sensor hydrostat
This interrupts the circulator's operation when the water temperature exceeds the maximum desired setting.
Compensator
It controls, by means of sensors, the ambient temperature, room temperature of the spaces and boiler temperature, intervening to adjust operation of the three-way valve so that it provides the required operating temperature for the underfloor system.
Valve actuator
The actuator is mounted on the three-way valve and connected to the compensator control panel. It determines the supply temperature on the basis of the outdoor temperature.
Circulator
By means of the circulator, hot water circulates in the circuits (loops) of the underfloor heating system. Power and cross-section (pump nozzles) are determined by the underfloor heating design (losses-loops) and vary according to the needs and requirements of the space we want to heat
Water Mixing System
The Water Mixing system is mounted on the Distribution Panel enabling the mixing of water to obtain the desired temperature of feed water in the horizontal system of underfloor heating. It is recommended mainly in cases of mixed heating systems (Underfloor and radiators). If the mixing system is chosen for the installation then separate devices and branches to the boiler are not required.
Wireless thermostat communication system
A wireless communication system (which does not use cables) where the thermostats operate as transmitters and a base operates as a receiver giving commands to the thermoelectric actuators on the manifold to open and close the circuits depending on the desired temperature.
This system provides an intelligent and flexible solution for cases when we wish to install at a later date separate thermostats to control the desired temperature in each space without the need to install communication cables.
