Hi. I’m having a loft conversion done in the Uk. My builder has made the connection for the hot water to the loft but since he has done this my hot water in the rest of the house is not getting hot. I have a combination boiler and the water gets to say 37 degrees ish but not hot hot for washing up or a nice hot shower. It always got hot hot before the new connection.
I’ve shut off the water to the loft and the water goes back to normal ‘hot hot’.
The builder has connected very close to the boiler (first spur connection) directly above boiler after the pipe rises to left of boiler and makes a 90 degree turn to the left. What I’m wondering is this simple a bad spot as hot water rises so I’m getting a loft of heat loss? If we connected not at the highest point of this pipework might it make a difference?
On photo green pipe is new spur to the loft. Red pipes are old hot water pipes.
Any help appreciated!
