Question: How to easily get hot water at home without the noise from a normal water heater reheating every 30 minutes, or waiting 10 minutes with an electric heater? I use a 1000 ml bottle and only need to fill it twice a day. I don’t want a device that stays on to maintain temperature. One idea is using a smart plug with a phone to turn on heating in advance from the bedroom, then pour into the bottle and turn it off.

Answer:

Here are several practical and easy ways to have hot water (around 70–100°C for drinking/tea/etc.) at home with your 1000 ml bottle requirement, focusing on minimal noise, no long waits when you need it, and no always-on temperature maintenance.

  1. Use a good vacuum insulated thermos flask (the simplest and quietest long-term solution)
    Boil water once or twice a day (using your current kettle or heater), pour it immediately into a high-quality stainless steel thermos bottle (1–1.5 liter size).
    Good ones keep water very hot (>70°C) for 8–12 hours and still reasonably hot (>50–60°C) even after 24 hours.
    This matches your twice-a-day need perfectly — fill in the morning and once more in the evening. No reheating, no noise between fills, no waiting when you want to drink.
    Just boil → pour → close. No electricity needed after filling.

  2. Smart plug + immersion heater or small travel kettle (your suggested idea, improved)
    Get a Wi-Fi smart plug (works with phone app).
    Connect a small, low-noise device:
    • A quiet electric kettle (some modern ones are much quieter than old models).
    • Or a simple immersion heater coil (very cheap, almost silent, heats 1 liter in ~5–10 minutes depending on power).
      From your phone (e.g., when in bedroom), turn on the smart plug 10–15 minutes before you need it.
      When ready, pour into your 1000 ml bottle and turn off via phone.
      No standby power waste or noise, only runs when you schedule/activate it.
      This avoids the 30-minute noise cycle of a big water heater and the always-on issue.

  3. Instant hot water dispenser (quiet, on-demand, countertop type)
    Many modern hot water dispensers (e.g., models like Breville Aquastation or similar under-sink/countertop units) heat water very quickly and quietly when you press a button.
    They often have good insulation and only use power during the short heating time (no constant reheating noise like a tank).
    Fill your bottle directly from it. Some keep a small amount hot with minimal energy, but choose one without a large always-hot tank if you want zero background noise.

  4. Small point-of-use under-sink tank (if you want near-instant at a sink)
    A tiny 2–4 liter under-sink electric water heater provides almost instant hot water at the tap with very little noise (only when refilling/heating occasionally).
    Fill your bottle from the tap. It reheats quietly and infrequently because of the small volume.
    This is more permanent but solves both noise and wait time.

The thermos flask option is usually the easiest, cheapest, and completely silent between uses — most people who only need small amounts 1–2 times per day find this works best.
