New Timer Required

[chrisdicko]

Hi,

My grans Central Heating and Water Heating timer has stopped working correctly and she's struggling with it now the cold weather is here.

This is the 40 year old beast:

Can you get a really simple one?

Something like this, but with two on, so she can easily do it?

She did say she always has to heat the water before the central heating will work. Is this true....down to the faulty timer, or do some systems work like this??


Thanks a lot for any recommendations.

She has obviously got gravity hot water with pumped central heating.
The Potterton EP2002 would do the job and is easy to use, available from Screwfix for about 50 quid.

Holty, your link doesn't work?

Spraggo, is she correct saying she needs to heat the hot water before the central heating will work? Should that timer just wire in the same as the current one?

just search for hortsmann tiara mechanical time clock

Oh yeah, thanks for that. Looks simple enough for her.

Will that be ok for her needs in terms of she said about needing to heat the hot water before the heating?

If she has a gravity ho water she would be correct, No, the timer will not be the same wiring and you will probably have to extend the existing wires, this should be no problem for an electrician.

To be honest she wouldn't know what she has unfortunately. All she does know if the water needs to be hot before the heating. So I guess it is gravity fed.

In terms of wiring, I guess it's a single live input, with two outputs; One for water, and one for central heating?

if the water must be heated first, then surely this is c plan, divertor with hot water priority? thats my limit though.
