<br>
Actually, you’re not too far off the mark.<br>
<br>
The thing you’re looking for is a thermal store, this can be used to provide both hot water, and water for heating typically it works better with underfloor as this requires a lower delta, radiators work best with a 40-50c above the room temperature.<br>
<br>
With modern heat pumps, using solar PV, and a heat pump gets you more hot water for your kWh.<br>
<br>
Cheers<br>
<br>
Stuart<br>
