Central Heating Zones - New & Replacement Systems

[chris watkins]

Lets say you got a combi, do you need 2 room stats (one upstairs and one downstairs if so where upstairs would you situate the room stat?) and a 1 channel programmer?

rodders the reason they want to have the heating spilt up into the two zone it that there is some energy savings to be gained if the heating in the sleeping areas (bedrooms) of the house can be turned off when no body in these areas, which makes sense if you think about how most people use there houses (bedrooms only need heating when we get up & then again when we go to bed) (unless you want a quickly in the afternoon, ar' they were the days !) sorry, day dreaming again !! anyway this means that you do need time control as well as temp (part L does state this) the easy way to achieve this is to use a programmable room thermostat upstairs controlling a zone valve. You can do the same downstairs as well, easer to link these to 2 ports rather than a 3 port.
Do you know how a 2 port valve works with the micro switch ???

if the property only has an upstairs bog them i would put the bathroom off the living zone.

I get the reason they require this to be done. I know how a 2 port zone valve works, but I wonder who actually does this? I been in hundreds of houses fitted loads of new and replacement systems and never seen it done.

What happens if someone wants a boiler replacement but just had new carpet and decorating and dont want all the boards up to fit an extra flow and return?

Not to mention the extra cost of copper and fittings, labour and room stat etc.

I'm finding it hard to believe this is done but I don't know?!

What should be done (by law) & what is actually done are not necessarily the same thing (like driving a 70 on the motorways) but it does save a bit & if you register your installations under part L you are certifying that it is compliant ! As usual it boils down to wether you do it by the book or not, if only the law was enforced we would all be playing on a level field !!! Fat chance but we should be pushing for it. (plumbing registration by the back door)

Never mind two zones there are plenty changeovers I come across without the required TRV's or temp control, haven't been flushed and the condensates dribble down the outside wall!!! Who polices building regs anyhoo's?

This is true. Always see no TRVs on new boilers etc,

As for who polices it, I guess building control officer?

Theres a morale issue here, what do you do if an old lady on a pension with no heating needs a new boiler. Do you tell her she needs all the controls to bring it up to part L or your not going to fit the boiler? Or just fit it and have a clear concience

 

[Koogatubac]

A very good point to prove, in a way they say its the installer to stress that these actions need to be done to comply with building regs. If they dont want it then really the boiler warrenty would be void since thats part of the benchmark... Hmm... But we all could do with a good payout

I totaly agree! In my opinion it's entirely up to the customer what they have or do not have in their homes! Who are we to tell them they MUST comply with building regulations? It is our job to inform them of new requirements and let them make the choice!

Are these regulations a MUST DO? Do we break any 'laws' if we do not comply with building regs? I do not know the answers, anyone know?
