Definitions
- the invention relates to water heating systems, more particularly to hot water production systems and more particularly to hot water production systems that heat and store hot water for exploitation and use.
- the water heater with buffer tank disclosed in the present invention has not been disclosed in the prior art.
- buffer tanks are reservoirs that act as additional spaces for storing water in heating installations. Buffer tanks are connected in series with the boiler or with the solar panels, and because of their very good thermal insulation they maintain the high water temperature for a long time.
- the purpose of the buffer tanks is to store hot water when it is produced during the operation of a boiler of any type, heat pump or solar collector and to supply hot water when the boiler or heat pump stops operating or when the sun sets and the solar collector now stops producing hot water.
- most buffer tanks are made of metal and enamelled, that is, carry a glass coating that is chemically bonded to the metal at high temperatures, about 850 degrees Celsius. However, enamel can often detach, resulting in difficult repair and ultimate corrosion of the tank.
- a further disadvantage of water heaters with buffer tanks placed on the market is that the water contained therein is water which is intended either for use or for heating.
- the result is that water continuously circulates inside the water heater and the buffer tank. This continuous circulation results in the accumulation, over time, of both salts and sediments, mainly sludge, inside the tanks.
- the water inside the tanks is under pressure, resulting in component stress and shorter life span.
- thermal insulation such as cast glass wool polyurethane, stone wool, ceramics, expanded polystyrene or any other suitable insulation.
- Another feature of the invention is the addition to the water, for reasons of usability, of materials that improve its energy transmission behaviour and its clarity, or that are added for aesthetic reasons as well as antifreeze to improve its resistance to low temperatures.
- An advantage of the present invention is also the operation of the system at atmospheric pressure, resulting in longer life span due to reduced stress.
- a further advantage, resulting from the above, is the possibility of constructing a water heater and buffer tank in the shape of a rectangular parallelepiped, which can pass through doors, and not just of a cylindrical shape, as is done to date.
- Figure 1 is a cross-sectional view of the new type water heater with buffer tanks of the invention.
- the new type water heater, with buffer tanks, of the invention consists of an outer container (1), Fig. 1, and an inner container (2).
- the two containers are made of a suitable plastic material, such as polyethylene or polypropylene, or any other plastic raw material.
- a suitable insulating material (3) is put in the space between the two containers. Examples of such materials are cast polyurethane, glass wool, stone wool, ceramic wool, as well as expanded polystyrene or any other suitable insulation.
- the capacity of this water heater and thus of the containers thereof can range from 300 litres to, for example, 5000 litres, but there is no limitation in constructing a water heater with a smaller or larger capacity.
- the outer container (1) body can also be made of a new technology two-component polyethylene feedstock, allowing the container with the insulating material (3) to be made in one step.
- the new water heater system with the buffer tank of the invention is installed on supports (8) which are individually adjustable for fitting in every space, regardless of the inclination of the respective floor. Inside the container (2) heat exchangers are located. They can take advantage of different energy production methods, representing a hot water production heat exchanger (9), an exchanger for energy produced by a hot water boiler (10), an exchanger for geothermal energy and a heat pump (11), as well as an exchanger for solar energy (12).
- the exchangers to be used may be metallic, copper or plastic, and their shape may be varied, being round or square, or of any other suitable shape serving the heat transfer process.
- a lid (13) which insulates and seals the containers while allowing easy access for possible service, extension or conversion in general of the system.
- all the hydraulic and electrical connections of the new water heater of the invention have side edges that are compatible with all conventional components and systems of current technology, making it easy to place the system in existing as well as in new installations.
- the inner container (2) is filled with water, which acts as a storage and energy carrier between the exchangers. This water remains in the container permanently and is not used for heating or as use water. For reasons of usability, various materials can be mixed in the water, which will improve its behaviour for energy transmission, its clarity, for cosmetic reasons, and also anti-freezing agents for its low temperature resistance.
- the inner container (2) may be filled with other liquids, such as oil-based fluids, high heat-capacity liquids, non-volatile ones and with a gasification point above 100°C.
- special salts with a freezing point and a melting point of 45-75°C can be placed in the inner container (2), having high special heat and high latent heat characteristics in phase change.
