Claim Text:
1. A method for producing a supply of heated water, the method comprising passing water through a heat exchanger unit, wherein the heat exchanger unit comprises: (a) a heat exchanger element through which the water may flow; (b) a reaction chamber having at least one inlet through which reactants may be introduced into the reaction chamber, and at least one outlet through which spent reactant may be removed from the reaction chamber; (c) a first dosing unit for introducing a controlled amount of a first reactant through an inlet into the reaction chamber; (d) a second dosing unit for introducing a controlled amount of a second reactant through an inlet into the reaction chamber; wherein the first and second reactants react exothermically and the heat thereby produced is exchanged with the water passing through the heat exchanger element, the introduction of the first and second reactants into the reaction chamber being controlled to produce a required level of heating; (e) sensors which in use monitor the rates of flow of the first and second reactants into the reaction chamber; (f) one or more sensors for measuring the temperature of the water; (g) one or more reaction monitoring sensors for monitoring the extent of reaction between the reactants; and (h) a controller operatively linked to the temperature-measuring sensors, the reaction monitoring sensors and the sensors for controlling the flow of the first and second reactants into the chamber so as to produce a required level of heating of the water, and for controlling the flow of spent reactant out of the reaction chamber.
