TRVs

[John Rumm]

Yup, I noticed that! ;-)

Yup, that would makes sense. Also zoning is only required for properties over 150m^2 which rules out the majority I would expect.

That is for control of the whole zone though (i.e. provision of interlock), not the individual rooms...

Its ambiguous, I will give you that. Other sources suggest that TRVs are required. You may be right though... proper interlock, timer control, and fully pumped system may be enough.

Indeed. I have never heard of a requirement to replace TRVs with newer or better ones. (other than perhaps some of the mechanical hot water cylinder control valves that used to be used to arrest gravity circulation). So in answer to the specific question (assuming the words of the plumber were correctly interpreted and relayed), he is trying it on.

One of many:

oil boilers were also required to be condensing from from April this year)

[Mike Barnes]

You're right, but it's a pain.

First thanks for all the replies, looks like the situation's not entirely clear. The house in question certainly has TRVs, whether all the rad valves are TRVs though I don't know. I'll see what's occurring next phone call.

things move on..I couldn't get one at all in 2002..

[Doctor Drivel]

That is 20 years out of date.

[Doctor Drivel]

That is unusual. They are boilers that go and go without any problems. The Toyotas and Hondas of the boiler world.

[Doctor Drivel]

Amazing!! this is what snotty uni's turn out. Appalling.....

[Doctor Drivel]

You didn't look hard enough

[John Rumm]

It *is* clear if there are already TRVs, they don't need replacing though...

[Ed Sirett]

The condensing exemption assessment is slightly less demanding with an oil boiler. That's about the only difference.

[Ed Sirett]

...unless they are broken in which case it's probably the best time to replace them.

[Andy Hall]

Really? How do you turn a Rolls Royce into a Honda or a Toyota?

Not that long ago, you were saying that they were RRs.

Did you not win the Eyebyeza holiday?

[Andy Hall]

or perhaps you're 20 years ahead of your time. Just think (hard though that might be), for your next alter-ego you could call yourself Eric Laithwaite.

[Doctor Drivel]

No Matt. A man of my time.

Given your physics is different to everyone else's, why shouldn't you have your own timezone too?

Owain

[Doctor Drivel]

It is? Well the ether is different your Jockoland.

[Andy Hall]

As in 'time gentlemen, please' ?

[Andy Hall]

It appears that "time gentlemen please" is about right.
