Abstract: For the production of the proximity capillary heater with high energy savings, subjected to appropriate electrical voltage (2) and equipped, upstream of the microfiltration apparatus (9) for the elimination of calcareous particles present in fluids and, downstream, of the nozzle (7) or connector, or closed circuit (Fig. 3) is used steel or graphene with high or very high thermal transmissivity, in case the invenction is used to produce food or drinks for human consumption the item will be industrialized in an appropriate material for foods. Such materials are well known to the expert in the field. In a preferred embodiment of the invention, but not limited to, is utilized a high or very high thermal transmissivity steel capillary tube (1), either bare or coated with ceramic material or composite or plastic, for food use where necessary. In this capillary tube (1), which can be grouped in bundles (8) as subsequently exposed (Fig. 3), are fixed (Fig. 2) electrical connections (2) which provide electrical voltage to the capillary tube (1) which will be, crossed by electric current and, therefore, by the Joule effect, heated. This invention, appropriately and adequately protected in accordance with current international safety regulations, and according to the technical specifications IPX8, has input of an electronic remote control (4) hydraulic micro-gate (3) that provides to open when you are asked to supply (5) hot water (or hot fluids) (12) and to close when the request is stopped. On the opposite side of the capillary tube (Fig.2), is placed a nozzle (7) for the exit of the hot water (or hot fluids) or for connection to a closed circuit or heat exchanger, with a temperature detector (6) connected to the electronic remote control (4). All the process of heating and dispensing, are controlled by an electronic card (4), of the prior art, which is adequately and appropriately constructed and calibrated for the entry of water in the capillary tube for the flow rate and pressure is atmospheric that it induced by pumps (10); the electrical power needed to heat the water to the desired temperature is more than 95% less that any other known heater system, by way of example this invenction goes from 1 ° Celsius for processing into steam according to the following table (degrees Celsius): Pressure [bar] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Temperature [°C] 100 120 134 144 152 159 165 171 175 180 184 188 192 195 198 201 204 208 According to precise calculations the power in milliWatts needed to heat the water at the temperature of 89 degrees centigrade necessary, for example, to produce a cup of coffee is of 3 watt, more than 95% less than the energy today used by the apparatus for production of coffee drinks at home or professional. Upstream of the micro hydraulic gate (3) is positioned a high performance filter (9), for microfiltration, with a preferred measurement of filtration of 20 microns, but still working in the range between 15 and 50 microns, over the slaughter of limestone for ion exchange to the extent of more than 95%, differentiable depending on water hardness, in particular area of use which shall thus retain not less than 95% of airborne particles and limestone to make sure that the capillary tube (1) is always kept clean internally. The size of the nominal internal diameter of the tube varies from 0.13 mm (insulin needle) to 1000.00 mm. The tubes can also be aggregated into bundles (8), more or less large, such as to achieve aggregations that can heat larger quantities of water or fluid for normal domestic or industrial use (eg 3/4 or 1 inch or larger). In these cases, the electronic control board (4) will be adequately calibrated to handle the desired temperature by varying continuously the electrical flows for each capillary tube being within the beam intrinsically higher temperature than the outside to the effect of known physical laws. In a preferred embodiment of the capillary proximity heater with high energy saving, subject to appropriate electrical voltage (2) and equipped, upstream of the microfiltration apparatus (9) for the elimination of calcareous particles present in fluids and, downstream of the nozzle (7) a bundle of tubes (8) capillaries under the control of the electronic board (4) provides heating of water as required at a temperature of 60 °C to serve the work of a washing machine. Even in this case the energy saving compared to a normal electrical resistance is greater than 60%. In another preferred embodiment, a suitable number of proximity boilers serving the phone of a shower (which due to the low consumption can be powered by a battery) by heating the capillary tubes that make the water out to the desired temperature without the need for mixing with water cold. A further preferred embodiment of the heater using proximity heating element. The water in a coffee machine involves heating of one or more capillary tubes capable to heat the water necessary for extraction from filter (11) coffee or hot drinks. Also in this case the paucity of energy required means that it is not necessary the use of electrical current from the network, but that the whole operation can be performed with a battery with a power of 8 amperes at 3,7 Volt. A preferred embodiment of the boiler proximity to high energy savings is to make the heating of the seats and the cockpit of cars powered by combustion or electric engine (Fig. 3). Systems and leading technology, know that the absence of thermal engines on vehicles driven by electric power, stored in rechargeable batteries, is a serious problem for the winter heating of the cockpit and the seats of this type of vehicle, of difficult solution. The proximity heater also work in a closed circuit, with a remarkable energy saving, it can provide heating of the passenger compartment with the bundles of tubes (8) properly placed serpentine on the floor and on the sky of the car as well as inside of the passenger seats or where desired. The electronic card (4) suitably calibrated will bring the temperature of the passenger compartment that desired very quickly. The same proximity heater can 'be used as well as a heater for the outlet nozzles by means of hot air. The combination of the three systems generates comfortable heat and energy savings compared to the state of the art more than 60%
