2nd fix Central Heating

typeractive

Just been searching the Broag instruction booklet to see if I can find anything obvious about bypass stuff.

Well I thought I needed 11 of these for the rooms listed:




Then either the valves you showed me for the hallway and garage:



Or the bypass valve for the one in the hallway (and I imagine I need some sort of a lockshield for the other side?):



Any of that sound correct?

The bypass does not connect to the radiator. Connects to flow and return and that's why it's a bypass.

The other person said to fit TRV,s on all the rads ,this is in correct information.

My apologies I didn't realise this was a completely new system - should have read the thread properly, as heating-eng says a new system should have a room stat and a rad with lock shield valves.
In my defence my info was right for fitting boiler trvs etc to an older system. and fitting bypass

Both qoutes below from Worcester site

• On new installations TRVs must be used on all radiators except the radiator where the room thermostat is sited, this must be fitted with lockshield valves and left open. All boiler replacement installations should have TRV’s fitted to radiators at least within the sleeping accommodation.
• An automatic bypass valve must be connected between the heating flow return where TRVs are used on all radiators.

I am sorry but this does not make sense. Second comment.
You cannot fit a TRV in the same room as a room stat, the room stat would not work correctly.
If you are a gas engineers then you need to brush up a little if not let the experts repond to the questions, this will be less confusing.
Thanks

A bit touchy there If you read it right I was agreeing with you not disagreeing. We always fit stat and lockshields on new systems.

Worcester state trvs can be fitted on all rads with an auto bypass valve- no mention of a stat. when upgrading an existing system.

New systems require stat and rad without trvs so not sure what you mean as i haven't stated that a trv is in the same room as a stat.

Must have been lost in the translation Anyhow got some prepiping to do for a 42CDi to do this afternoon- been sitting skiving for a while having a long lunch break - the thought of going back under a floor again Enjoy your day

Building regs say a room stat needs to be fitted. This has always been the case.
Where a room stat is fitted then lock shield valves are normally fitted. Which normally will act as. Bypass.

Don't mean to sound touchy. I was commenting on the second quote you gave, saying that this is wrong. Not saying you are wrong just the quote you made.
