You can, but the problem is that warm water isn't that useful.
Unless your system can regularly heat up to >60C to kill legionella then it will need external heating.
Secondly, when the external temperatures are high there's very little need for warm water. Perhaps a few dozen litres for washing. No one is taking a hot bath on a summer's day!
If you have the space, you can store the hot water underground and then pump it back up in winter for heating. But that's expensive.
- hutzlibu 3y ago"You can, but the problem is that warm water isn't that useful." Depends on your other systems. Dishwater wants hot water(but usually has no input for hot water), washing machine(some do). And if you have a house with 4+ people who like to shower a lot .. it adds up very quickly. And yes, heating. Now are already the days (in europe), with cold nights and mild but sunny days. So .. it makes sense in theory, but not so easy to economically make use of as of now.
