A mixing valve having a housing and first and second flow control valves. The housing has a mixing chamber, a first outlet, and a second outlet. The first flow control valve controls fluid flow through the first outlet to the mixing chamber, and the second flow control valve controls fluid flow through the second outlet to the mixing chamber. The first and second outlets each have a size so that the mixing valve has a flow coefficient of approximately 2.5 in a mid-open position of both flow control valves, and the housing has a length dimension, a width dimension, and a thickness dimension, and the largest of these dimensions is no more than approximately 65 millimeters.

An apparatus for filtering water has an interface and a filtration/purification canister removably mountable onto the interface. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The interface provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus from backflowing into the filtration/purification canister and contaminating the portion of the filtration/purification canister downstream of the filter/conditioning/purifying medium held within the filtration/purification canister and thereby causing water exiting the outlet port of the filtration/purification canister to be contaminated.

An automatic control valve actuator assembly is configured to control opening and closing of the valve via positioning of a valve closure member. The valve actuator is further configured to determine the volume of fluid flowing through the valve. In an embodiment, the valve actuator includes an integral energy consumption calculation and retention module configured to calculate heat energy for energy consumption tracking.
