Abstract

The heater provides water at a small raised temp. and comprises two tubular chambers (1), fixed on a support. These have orifices (12) along the length of their top section and are connected by a conduit (4), including a water circulating pump. One tubular chamber acts as a hot water distribution reservoir and includes a thermal pocket (14). This distribution reservoir has an upper longitudinal insulating barrier (13), fixed by its edges to the internal chamber surface. Together with the orifices, this forms a compartment closed at one end.

Description

 The present invention relates to a compact electric boiler and of reduced dimensions intended to ensure the heating of a dwelling by producing water at low temperature for heated piancher.

 The boilers existing to date for heating residential buildings generally comprise a central heating unit connected to a distribution member allowing the connection to said center of the pipes serving the various premises.

 However, these boilers are of a large size and require for their implementation many welding operations and / or brazing, which requires for their installation to use skilled labor.

 On the other hand, the water, which is brought to a certain temperature in the heating plant before being sent through the various pipes distributed in the dwelling, generally exhibits significant temperature differences from one pipe to another. .

 The object of the present invention is to remedy these drawbacks by proposing a compact and small electric boiler which produces calves at low temperature while ensuring better caloric distribution from the first to the last heating pipe, with very low loss. heat, and which can be manufactured at low cost and easily installed by non-professionals.

 The boiler according to the present invention is essentially characterized in that it consists of two tubular enclosures fixed to a support, one serving as a hot water distribution tank and incorporating an immersion heater and the other as a return tank and which can also incorporate an immersion heater, at the upper part of which are regularly spaced apart orifices allowing the connection of said enclosures with the heating pipes of a dwelling, the two enclosures being connected together by a duct provided with a pump for ia water circulation; at least one of the enclosures, and more particularly that serving as a distribution manifold, comprising longitudinally, at its upper part, a wall made of an insulating material, joined by its edges to the internal face of said enclosure, on both sides 'other of the holes, so as to form a compartment which is closed at one of its ends.

 The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment thereof.

In the attached drawing
- Figure 1 shows a perspective view of a boiler according to the invention.

 - Figure 2 shows a sectional and plan view of an enclosure of the same boiler.

 - Figure 3 shows a sectional view along line I-I of Figure 2.

 - Figure 4 shows a side view of the same boiler.

 If we refer to these figures we can see that a boiler according to the invention consists of two enclosures 1 and 2, welded at their base on a support 3 formed of two transverse tubes 3i and 32, threaded at their ends in view to allow their attachment to a wall wall. The speakers i and 2 are each provided at their lower part, not ioin of the tube 31, with an orifice 11 and 21 in each of which opens i! end to a tube 4 connecting the interior spaces of the enclosures 1 and 2, which on the other hand are provided, at their upper part and longitudinally, with orifices 12 and 22 ae pius small diameter, regularly spaced so as to form a network ae distribution to water connected to heating pipes.

 Each enclosure 1, 2 comprises at its upper part a wall i3,23 folded in the form of a truncated V, the sides 131,131 'and 231,231' of which are secured by their edge to the upper internal face of the speakers i, 2, on both sides. other of the orifices 12 and 22, and whose flat bottoms 132 and 232 are located opposite the orifices 12 and 22, each wall 13,23 delimiting a compartment 130,230 which is closed at one of its ends.

 The enclosure 1 further contains an electrical resistance 14 of the immersion heater type extending under the wall 13 and over approximately ia of its length.

 The operation of the boiler is as follows: the return water coming from the pipes of the building to be heated passes through the orifices 22 and enters the compartment 230 of the enclosure 2 from which it leaves through the opening 233 to be discharged through the orifice 21 in the tube 4 and be conveyed by the orifice 11, under the action of a pump 6 placed between the orifices 11 and 21, towards the enclosure 1 or the air is heated by means of the immersion heater i4, then it enters the compartment 130 through its opening 133, before being sent through the orifices 12 in the pipes intended to heat the house.

 The compartment 130 made of insulating material makes it possible to achieve good temperature homogenization of the water heated by the immersion heater 14, so that it leaves through the various orifices 12 at a temperature almost identical from the first to the last.

The boiler according to the invention thus offers the advantage of optimum heat distribution between all the heating pipes.
It goes without saying that the present invention cannot be limited to the foregoing description of one of its embodiments, liable to undergo a certain number of modifications without departing from the scope of the invention.
