can anyone advise me about fitting geo horizontal rads do you need to fit the flow to the t.r.v. side and if you don't what will it do. The new geo is not allowing the water through so hence wont heat up

    Hi David,

    I can confirm the flow does need to be connected to TRV. Unfortunately if the flow is not connected into the TRV you will lose output from the radiator but also over time you will begin to hear a knocking sound coming from the valve itself. If the water isn't circulating properly you may also want to try bleeding the radiator.
