With a hotel there's no need to ask for the heating or look after the pool: you just go down for a swim. Ischia, a volcanic island in the Bay of Naples, draws hot thermal water from beneath its soil. Here are the 41 hotels I've selected on Ischia, all rated at least 8/10; I particularly recommend Albergo La Reginella, Hotel Villa Durrueli Resort & Spa and Parco Maria Hotel Terme.
Each city has its own selection, with a page for each type of accommodation.
Places are ranked from highest to lowest rated. The yellow bubble shows the advertised water temperature, when it's known.

These places don't have a confirmed heated pool, but they do have a hot tub: the water is hot all year round. A good way to relax in the warm.
These places were suggested to us directly by their owners. The heated pool is declared by them; they don't yet have enough guest reviews to join the selection.
In my selection, the top-rated is Albergo La Reginella (Hotel), with 8.9/10 (667 reviews · Kayak). Next come Hotel Villa Durrueli Resort & Spa (8.9/10) and Parco Maria Hotel Terme (8.9/10).
None of the places selected on Ischia clearly advertises a pool heated all year round. At Parco Maria Hotel Terme, heating is seasonal (seasonal (hotel closed november to april)). Albergo La Reginella, Hotel Villa Durrueli Resort & Spa and Hotel Terme Tritone Resort & Spa have an indoor pool, sheltered from the wind. Either way, ask for the heating dates before you book.
Advertised temperatures: 32 °C at Regina Isabella. For the other places the temperature isn't published: ask the property.
Yes: Albergo La Reginella, Botania Relais & Spa and Hotel Terme Tritone Resort & Spa also have a hot tub in addition to the heated pool.
The word "heated" on a booking page isn't enough. Every place must have a rating of at least 8/10 (or 4/5) and carries one of these four levels.
Guests mention the heated water in their reviews, with the season when they say so.
A journalist or guide who stayed there describes the heated pool.
The hotel or the platform says so, but I haven't yet found a review that confirms it.
Heating isn't specified, but the water is sheltered from the wind and cold air. Ask for the temperature before you book.
I left these out because guests report water colder than advertised, or because no heating or indoor pool is mentioned.
