zoned heating

[th3pony]

I was looking at getting zoned heating in my house but my other half wil not have wireless control units is there any other way it can be done

 

[Whn1]

Hard wired ones

 

[lame plumber]

dont tell her they are wireless, take charge

 

[Whn1]

Quickest chasing, plastering and decorating ever done.

 

[th3pony]

I wish ha ha nothing gets past her, can you suggest a good system to get

 

[lame plumber]

programmable trv on each rad?

 

[th3pony]

can it be done by putting valves on the pipes ?

 

[lame plumber]

get an engineer to check out what you have now to see what can be done

 

[ambrosia]

why doesnt the missus dislike wireless

 

[lame plumber]

why doesnt the missus dislike wireless

she does dislike wireless, she doesnt dislike hard wired

 

[ambrosia]

eh yeah what he said,
having a dyslexic moment

"why does the missus dislike wireless?"

 

[lame plumber]

Cos she does!!!!!!!!!!!!

 

[stevetheplumber]

that time of the month lame?

 

[lame plumber]

no , just know women, not worth arguing.

 

[AWheating]

i like wireless................bras!




not on me i must add.

do you understand that the heating system will need a repipe? when its done run some cables at the same time.

 

[billybob150811]

two ports each with a separate timer could mean two ports in awkward places get her a tool kit and multimeter for her birthday think the shine will wear off her idea

Pace maker?

 

[th3pony]

ok back to question in point the rads are pipe upstairs one circuit and down another one, so is there a valve I can put on the pipes that can control either up or down and do they wire into boiler somehow

 

[billybob150811]

you don't wire back to the boiler you wire back to a terminal strip so you can include temp control and its easier to put two two ports as three ports tend to be priority or spring return

2 x 2 port valves, room stats, timer and boiler all wired to junction box power'd by a double pole isolation point (sometimes through boiler first) pump either in boiler or external.

heating engineer or sparks needed, must be wired/tested/signed off by competent person.


are you sure the system is seperated? its not gravity upstairs?

 

[th3pony]

yes we put pipes in ourselves so have 4 rad pipes 2 for downstairs rads 2 for upstairs. I'm a spark myself let me see if I've got this right the 2 x 2 port valves the room stat/timer and the boiler all connected up in jb

 

[AWheating]

yes, you need a room stat for both zones.

follow the honeywell wiring guide and your boilers manufacturers instructions. Be careful tho, some boilers require you to be gas safe registered to remove the case.

you will need to fit a bypass valve before the port valves across the primary fow and return.

 

[th3pony]

ok I'm pretty much there on this now it's a lot to get head around the wiring diagrams alone are headb spinner but not seen anything about this bypass valve what is it for

 

[AWheating]

its to ensure min flow rate for boiler/pump is always available amoung other things. Some boilers may not require one, many do and its best practice really. When both motorised valves have shut closed or all trvs have closed for example the pump may still be running (pump overrun) and need some form of circulation.

 

[Howsie]

Why don't you get someone in to do it for you?

 

[th3pony]

because i like a challenge and i am trying to keep costs down, ive got all the electrics sorted in my head and sourced all the parts off ebay. 2 x 2 port valves, 1 x 10 way connector unit, 2 x room stats and 1 x 7 day 2 channel programmer. let me know if ive missed anything

 

[th3pony]

Enlarge

HONEYWELL ST9400C1000 - 7 Day Programmer 2 Channel

is this suitable for what i need

mop and bucket

 

[th3pony]

can anyone suggest a suitable programmer for what i need

 

[lame plumber]

a 3 channel one

 

[doitmyself]

Which boiler do you have?

If it's a combi you will need a 3 channel timer (2 CH, 1 HW)

Have you thought about programmable thermostats instead of separate thermostats and programmers?

 

[th3pony]

what is a good 3 channel programmer

 

[AWheating]

unless your house is over 150m2 you dont need timed control in both zones, although you may want it.

no , just know women, not worth arguing.

And don't you forget it!
