Abstract (en)
The present invention discloses an adapter capable of being attached to a gas water heater to achieve a central heating function. The adapter comprises a heat exchanger having a first fluid passageway capable of being intercommunicated to the gas water heater, and a second fluid passageway interchanging heat but physically isolated with said first fluid passageway; a first diverter valve connected to the first fluid passageway and being operable to selectively connect the first fluid passageway to the gas water heater thereby allowing fluid fed from the gas water heater to pass through the first fluid passageway. By employing the adapter as described above, the existing gas water heater can be upgraded to a gas boiler by simple modifications. As a result, the total invest is reduced for users, and cost of development and manufacturing is decreased for manufactures.
