Dear Sirs,<div><br></div><div>I model a building with under floor heating which gets the desired hot water from tank which is connected with a solar collector. My question is do I have to connect two storage tanks one with a close loop with the solar collector which pumps hot water to another one that is connected with the building or the one is enough for this case?</div>
<div>Thank you</div><div><br></div><div>Regards,</div><div>Eva </div>
