    Even in the winter, washing our hands we don't use enough hot water for the hot to reach the taps, but loads of hot water for a bath, and loads at the kitchen sink once enough water run off for the hot to arrive.

    But in the summer months the central heating boiler is run ½ hour Mon, Wed, Fri and Sun unless we want a bath, and in the main it runs for 20 minutes then cuts out on boiler thermostat. And in the main we do have water warm enough to do dishes when required, however it depends on how much water we use, so what would be better is some form of thermostat on the hot water tank, however it is not an easy route to get cables from top floor to basement where the boiler is, so looking at how to get reliable hot water in the summer.

    Loads of ideas, from a hot tap to a wireless thermostat, what would be good is to feed hot water to a water heater in the kitchen so don't need to select which tap summer or winter, is simply gives hot water, but not much room.

    As to wireless looking at around 9 to 10 meters through two floors. If the hot water tank was on outside wall easy, but it's not, so cable would need to go into loft then across and down outside wall, and no easy access with ladder to pin it to wall.

    Alexa? Connect thermostat as sensor, then wifi to a relay which determines whether the boiler needs to heat the tank. If wifi will not go the distance, add a wifi repeater.
