FR2484613A1 - Water boiler for open fire - has indirect coils for domestic hot water and solar heating supplied from inlet at top of vessel - Google Patents

Abstract

The boiler consists of a vessel having a lid with a water-tight seal. The vessel is suspended over the fire on a hook. The water in the vessel is supplied to a central heating circuit through the flow pipe and returned via the return pipe. Domestic hot water is heated in the coil providing heated water to the storage cylinder through the connection and receiving cool water through the inlet. Solar heating from a collector is utilised in the coil which is supplied with water at the top inlet and returned to the solar panel through the outlet. The size of the boiler can be tailor made to suit each individual installation.

Description

 The object of the invention relates to a device for recovering calories with water circulation, for fireplaces with fire.

 I1 is intended to allow a capture of the calories released in the hearth of the chimneys.

 In devices of this kind, hot plates with air or water circulation were used.

 This appliance in the form of a cauldron, can be adapted in all kinds of fireplaces, without any modification of these.

 It consists of a wall containing a reserve of water sufficient to supply several radiators with also the possibility of adapting an exchanger for the production of domestic hot water as well as a solar exchanger.

 In the accompanying drawing given by way of non-limiting example of the embodiments of the subject of the invention; the cauldron is shown in cross-section.

 The cauldron is constituted by a wall1 with inside the water storage for the supply of the radiators.

 Fixing of the lid of the cauldron by gasket 3.

 The lid 4 is closed either by the handle or by fixing screws around the cover of the cauldron.

 Hanging hook 5, plugged into the wall for the support of the cauldron.

 The upper part of the cauldron is provided with a starting pipe 6 for the radiators.

 The lower part of the cauldron is provided with a return pipe 7 for the radiators.

 A thermostatic probe 8 allows regulation.

 The upper part of the cauldron is provided with a starting pipe 9 for the hot water tank.

 The lower part of the cauldron is provided with a return pipe 10 for a hot water tank.

 Inside the cauldron are the exchangers 14 for the production of domestic hot water and 13 for the solar scrpentin.

 -The upper part of the cauldron is provided with an inlet pipe 11 for the solar panels.

 The lower part of the cauldron is provided with a return pipe 12 for the solar panels.

 The base of the cauldron is provided with a drain pipe 15.

 The cauldron thus constituted, allows use for central heating and the distribution of domestic hot water.

 However, the shapes, dimensions and arrangements of the various elements may vary within the limits of the levels as well as the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
