haythorn_1 Posted July 8 Posted July 8 Looking to order a UVC soon from Telford for my ASHP setup. Does anyone know when you would use the hi-flow variant versus the normal one? https://www.telford-group.com/product/tempest-heat-pump-pre-plumbed-simplified https://www.telford-group.com/product/tempest-heat-pump-pre-plumbed-simplified-hiflow
JohnMo Posted July 8 Posted July 8 Think the only difference (I see) is the 3 port valve and possibly a different pump if you needed one. Small heat pump, ordinary one ok, big heat pump high flow would be my take on it.

He’ll look after you with a price for the Telford kit. Lots of others here have bought from them.

Nickfromwales Posted July 8 Posted July 8 They both seem to have the same coil surface area, so not sure what high flow actually refers to here. Ask Trevor for a proper explanation is my 2 cents.

Nickfromwales Posted July 8 Posted July 8 57 minutes ago, JohnMo said: Different 3 port valve and pump It's just a jump up to 28mm from 22mm then. Scan read it whilst multi-tasking, which never goes well. TBH all the Telford cylinders at 250L and upwards come with 1" BSP (so 28mm) connections/coil, so not sure any would impacted by being on 22mm if the cylinder volume is that much lower and it had less work to do?
