General question - is it reasonable to ask my installer if he balanced system after powerflush, new boiler, new cylinder and three new radiators? I'm putting together a list of things I want my installer to look at when I ask him to come back

Effort appreciated

Flow pipe warming up before the return on the boiler. The flow pipe connecting to HW cylinder (top pipe) is warm but not as warm as the flow pipe going into boiler although they are connected to same pipework.

Heating is on and right now top on is hot and bottom one cold. What's the best time to check which pipe gets warm first?

I will try again

two pics showing cylinder connections *** You can insert pics using copy and paste ***

posted a pic about hour ago but needs to approved before it's shown...will try to post it again *** You can insert pics using copy and paste ***

Hi Ian i think I have figured it out - the flow and return on the cylinder coil match up with the flow and return on the boiler

I've attached a picture of my HW cylinder - not sure where to look to check if flow and return to coil is reversed *** You can insert pics using copy and paste ***

no...the old system was perfectly installed and had no issues for 14 years. Unfortunately that plumber had retired so went for a new guy. The old plumber checked everything and his installation looked very impressive. Can't say the same about the new guy who took a year to complete the...

Credit to your Dad for being switched on enough to know what to look out for - Unfortunately I'm learning the hard way

I agree - I am concerned the installer didn't do the obvious checks despite having credentials and recommendations. I will give him the chance to put it right but my confidence is not high. On your point about the pump setting, I agree. It made no sense to me to put the pump speed higher so I...

I've contacted the installer and waiting to see what he says

I switched off the nosier radiators overnight near bedroom and finally got a decent nights sleep. I've checked the radiators with a thermometer and (for most of the radiators) the Lockshield pipe is the higher temperature flow and valve is the return. There is one radiator in hallway where the...

Is it true to say the flow side of a radiator is always hotter than the return?

thanks

Apologies for my ignorance but how installers swap the flow and return? I will check the body of the trvs for vibration when banging occurs. Thanks

Thanks - thought first one was trv as the otherside of the radiator is a lockshield valve I've used to adjust flow and all my rads were upgraded to TRVs. Now after 14yrs I just found out that wasn't true. When I do switch off the TRV valve banging isn't so bad - for the loudest radiator near the...
