Unvented Cylinder and Boiler

[saint7073]

I'm in the process of having new central heating and have opted (noticed that) to install an Ariston unvented cylinder (Sti 210?).

I've noticed that the boiler being installed is a Worcester Greenstar 30Cdi.

I've quickly read that this boiler is a condensing combi boiler. Is this correct?

I was under the impression that having the unvented cylinder meant that I wouldn't have a combi boiler.

Can anyone advise or explain? I've had a couple of issues with the builder and would like to ensure that this system is correct etc.

Thanks in advance.

There is a 30CDi system boiler

The Worcester Greenstar 30CDi is an open vented or if you fit a sealed system kit an system boiler. It is not a combi.

Unfortunately manufacturers label their boiler confusingley for the end user these days.

The combi is the Greenstar 30CDi combi

There used to be an older combi that was just called a 30CDi.

They have probably chosen this for its output as the Greenstar isyatem only goes up to 24Kw.

Thanks for your super quick response - it's slowly starting to make sense.

One last thing...

Does the above setup need to have a wall mounted thermostat? I hope not because there doesn't seem to be one installed at the moment, and all walls etc. have been plastered!

Thanks in advance

You can fit a RF thermostat. No wires!

Do you know if this setup will need a thermostat - I know I didn't need one when I installed a combi in my previous house?

and how much are these RF thermostats?

Yes, this system requires one.
