Underfloor heating problem.

[ee0jmt]

I have just had my underfloor heating manifold connected to my aga central heating system. The problem is that there is no heat on the flow to the manifold.

The manifold (ground floor) has been T off of the hot water tank loop (upstairs). The T fittings are hot but the pipe leading to the manifold is not apart from immediately next to the Ts. There is a pump next to the aga (ground floor). I'm guessing that the flow of water is going straight across the T and not feeding the manifold.

There is a pump on the manifold and I have flow going through each oh the underfloor heating circuits. It would appear that the
Manifold pump is not sucking any water in.

Is it possible to put another pump on the flow to the manifold which I can switch it on at the same time as the manifold pump?

Yes and no. You will need to reconfigure main pump. I really hope this isn't a solid fuel gravity hot water aga!

Oil aga. Its fed off the gravity circs. Will never work.

Needs doing properly.

I agree, your aga is like Simon says , Gravity circulation, and it's the gravity circuit that you've teed into, this will never work, the pump that's near the aga I would've thought fed rads ???? Do u have rads,
Is the aga gas ,oil or is it an uncontrollable heat source
Best to get a qualified engineer in to advise n fix,

Its oil and yes we have rads downstairs only. Is it possible to pump that circuit?
