secondary hot water return query

[jimbosweed]

Hi, this is my first post so many thanks in advance. Im currently installing a new unvented cylinder with a hot water return circuit. I am not familiar with these return circuits, so wanted to query something. The cylinder is on ground level in garage. Hot water circuit leaves the cylinder and splits to first floor and ground floor. The hot water return also splits and goes up to first floor and down to ground floor. where can i tee the return pipe from the ground floor to the return pipe going into cylinder, to ensure the hot water flows around the first floor and the ground floor return circuit. Im logically thinking about teeing in behind the bronze pump, (negative side) so that it hoipefuly pulls the hotwater from both the first floor and ground floor, sorry if this sounds complicated but like i said (my first post) cheers

Should be ok with what you're doing, what size pump is it?

You may need to fit DRV's (Double regulating Valves) to each return leg at the point where they common up on the suction side of the pump for balancing purposes

Oventrop are the one to get but if its not a big run then possibly not needed.
