I've just had a back boiler removed and combi boiler installed and have noticed that my radiators are heating up when using the hot water. I've been told this is due to the residual heat being moved around the system once the hot water is satisfied. But the radiators are heating up as soon as i start to use the hot water not afterwards unless i turn off the TRV's on the radiators. I've checked the position of the diverter valve via the boiler and it says it's in position 2 (DHW).
Any idea as to what's going on here, I'm i right in thinking that something isn't quite right with the install or is this normal?
much thanks for any advice.
