Issue with zoning a central heating circuit

[Pipes]

Hi there,

I have recently fitted a heat only boiler in a premesis that has just been halfed into two different sections. Central heating only (no hot water circuit as it was not needed)

The first section is to be used as a office and the second section is to be used as a living area.

*When I started the job originally it was all one office so it was just one big heating circuit that worked from a programmable room stat. ( Worked great! )

However now he wants the circuit to be halfed into two different sections.

I went back and fitted two zone valves and made some alterations to the pipework etc...

My main question is: could 2 wireless programmable room thermostats be wired to the system to control both zones independently? Or does it get complicated as there is no hot water circuit?

Two wireless room thermostats would be your simplest approach.

we are not seeing what has been done with the pipework!
two programmable wireless stats would do it.

what controls are already in place?
why would the lack of a hot water circuit complicate things??
why no need for hot water??

Excellent thanks a lot. I hoped that would work!

Which brings me to another question, do you know if 2 wireless Honeywell programmable room thermostats would interfere with each other?

Many thanks for the help

Cheers, yeah I can appreciate you can't see what I have done.

It's a strange setup. Customer wanted a central heating system fitted in an office. All good so I fitted it, a few weeks after complete he then told me he was planning to live there and split the office in two for a seperate living area!! Hence me now zoning it.

As for no need for hot water, he had an electric shower and instantaneous water heaters at all sinks and basically didn't want to fork out for a cylinder!?

It's crazy, I did explain to him that it would be a far better setup but there is no telling some people.

At the moment it's just running as one big heating circuit (sealed) off a standard wireless room thermostat until the spark gets there tomorrow. I have fitted 2 2port valves ready for it to be 're wired.

I was just curious if it would work because my electrical knowledge isn't brilliant and I thought that a traditional s plan has to include hot water.

Cheers for your help

the boiler doesn't know what it is heating, it just responds to the demand.

might have been better with a combi.

Follow a S plan wiring plan , instead off hot water , use the other heating zone ,,

They usually have dip switches that allow you to avoid crossover.

Pretty easy to set up. Don't forget bypass and pump needs to be set in right location.

Thanks alot! I feel a bit stupid now...

Cheers

Hardest question in the world is the one you don't know the answer to

Don't !
Its worse when you don't ask!

or the spark could have told you how to do it....
that would have been the time to hang up the tools and become a plasterer!

Havent used those stats yet, but cant see the problem?
I gather the stat controls the zone valve which then turns on the boiler ?

What you want is a Honeywell Sundial RF 5 pack. It comes with a two zone programmer with two RF room stats.
