Help boiler timer replacement

Elouesa_2

I have moved into a rented property and aside from issues with floorboards gaps etc British Gas have told me the gas usage is incredibly high.

I can see why as the property has an old timer that you either have to manually turn off or have on at least 3 hours a day. It's a Landis and Gyr timer with the white a red tabs that let you do on, once, twice, off. Sadly I understand you can't have it so only hot water in morning and heating in evening. Or just only both for an hour or two in evening.

I ideally want a digital timer that I can program to just heat the hot water in the morning (I'm not in long enough to care about the heating) and then 7 day programmable so I can change the times for the main heating coming on.

The boiler is an old potterton but seems to be surviving well so I can't see that getting changed any time soon, and I don't use the immersion heater.

There is a dial thermostat in the living room.

I'm hoping someone here will tell me it's an easy swap over to buy a fairly cheap standard 7 day digital timer that can be fitted easily by a competent person (brother is an engineer on planes so good with electrics).

Any thoughts?? You'll be helping me in my lone little flat greatly!

I have always used Drayton and this one should be suitable. You can buy it from here. Other makes and suppliers are available.

Both links work for me: Drayton and Screwfix

Hover your mouse over the words "this one" and "here".

Take note of the exact model of Landis and Gyr timer you have - then do a search online for a replacement model. We had an old Landis and Gyr timer which the Drayton LP822 was a direct replacement. This meant that the mounting plate and wiring did not need to be touched! Just switch off power - unscrew the grub screw (underneath) and slide up and off. Slide new under down on to the mounting plate and electrical terminals. Tighten the grub screw. Switch power on. Set times...


Good luck.

You may not be able to have completely separate heating and hot water without making alterations to the plumbing and putting in a 3-port valve.

Usually you can have water only, or water+heat, but not heat only.

As Above, it really depends on how it's plumbed & wired it might not be as simple as just changing the time clock

Thank you for the advice!!

To be honest I'm less worried about the water being on when the heating is in the evening - I just don't want the heating on in the morning, just the hot water.

Also I'd prefer not to have to have the heating on for 3 hours a day which is the minimum those pins will let you.

How do I find out which model it is? It doesn't seem to say on it anywhere?

Could it be the RWB2? Try here for a picture or could you post a picture of the existing one?

Elouesa_2

Yes that's exactly the one!!!

I looked up and the internet seemed to suggest a Siemens landis staefa rwb29 programmer as a possibility. Sadly as I'm new I'm not allowed to post a link.

Would it be as easy to change over as it suggests?
