Its a council house so will have to go through them.

We have a Honeywell st-799 heating timer on the wall but a slight problem,i want it to heat the

hot water up for an hour on a afternoon but you cant do it on its own as there are 2 timer setting.

We have economy 7 so we get hot water on a timer i set by the water tank on a night (cheap rate)

Its great and a quarter of the cost 7p kWh and 1 hour and its so hot.

Set the heating and all sorted on twice morning and night if needed but cant set water separate.

Is there a timer out there that you can set them both independent,i need heating twice but water once.

Don't want hot water on the morning as hot off economy 7 that works on the night.

This is a question for an electrician more than a plumber . . . does the timer / programmer not have the option of setting the hot water to on twice per day ?

From a quick google it looks identical to mine, although I don't have E7,- there is the option of setting the water to heat twice per day at times to suit you.

If the programmer has been installed to work outside of E7 hours the hot water will obviously cost more when demanded outside of E7 restricted hours

If the programmer is connected only to E7 it'll only work at the times relevant to E7

To test this just slide the water switch to '' CONT '' outside of E7 hours & if it works then you'll get hot water at any time you set on the timer settings.

If setting the water switch to '' CONT '' outside of E7 hours doesn't work then either a separate programmer needs installing or the electrical connections to this one need altering, which is a job for a qualified electrician.

Did not think i would get a reply on this so thanks.

No they both work separate not along side and i do know this 100% as you can set the timer what ever time.

See you economy 7 does the immersion heater on the tank ( electric)upstairs and had for years and a lot cheaper.

The heating timer does the gas side downstairs with the timer like you said you have.

Say i want the heating on twice i can also have the hot water on at the same times if set to twice or once.

But say i wanted heating on in the morning but no hot water you cant set it as they run side by side on the time.

You have the heating slide ( off/cont/twice/once) like the hot water slide but if you slide the both on twice its the heating times.

You cant set different times for the both which would be good.

Yes if i put it to CONT for 30 mins it gets hot say afternoon at 4.

Just wanted to know if there is a timer that i can look into and see if i can get fitted that works independent.

2 separate time setting..

Do you have a wall mounted thermostat that controls the radiator(s) temperature ?

Are you saying that your Honeywell ST 799 cannot be set to have your water heated independently of heating times ?

Setting the water to '' CONT'' clearly works outside of E7 restricted hours - as you have proven - so you should be able to set the programmer timer to heat water at anytime you like for any amount of time you like

This programmer can be set to heat water at different times to heating.

I will try and explain what goes on.

You see on the link above you have the 3 slides like yours you say,i think.

First set the times on the top one,say 5am in morning until 9am put it on auto then.

5pm afternoon 7pm.

Set the heating to the Twice and then it will come on the set times or ONCE will come on

the start of the first time (5am) and off on the last time what is set to (7pm) once works this way.

The hot water one slide to once how i want it just for afternoon but i cant set a different time.

The time will just be the same time what i set so if i did set ONCE i will get (5am till 7pm)

You would of thought if you just slide the heating one you would get a diferent time setting but

you get the same time that you just set for the heating.

You should be able to set a different time, the fact that you can't must mean that the programmer is linked to the E7 restricted hours electrical supply.

As the council own the property I can only suggest that you contact them to install a peak hours / time hot water programmer

Its just the timer,PH jones told me last time they came that the timer works side by side with hot water.

Its so hard to put it into words what i mean :)

There is only 1 LCD time set for both,you would of though you could slide the water one and set it.

Slide the heater one and set it on different time and all done but they said it don't work like that.

You cant run the both at different times.

OK . . . try setting the heating to CONT & control it with your room thermostat, basically using that as an on / off switch, & then set the water to come on whatever time you want

LOL 2 minds think alike

That is what i do in the winter i just set it on 24/7 for the heating at a set temp if i need to do that for a while

or just hit the hot water onto CONT in the afternoon if needed which is the easier way.

I asked the council about 3 years ago to sort out the thermostat control on the rads as we aint got any

just off and on,no numbers what you can set them to so some are hot and some just warm

and still waiting but that's another thing as i can manage that just leave them on.

Thanks for your help and just was seeing if anyone have one where i could look into that does both.

That's the thing . . . my timer / programmer, which is identical, does do both - I can have heat or hot water or both at any time independently of each other - but I'm not on E7, which I why I think the E7 is controlling your programmer / timer

How would you et yours up to work off different times,see i might be missing something as we

haven't had it in long.

Say you wanted the heating on twice but the hot water on once and not the same time.

Say heating on 5am till 8am then 3pm till 4pm

Water on just from 1pm till 2pm.

Firstly set the day of the week & the correct time . . . then slide the heating slider to the desired position ( once or twice ) then, slide the AUTO / SET slider to the 1st ON position & then using the + & - buttons set the first time ON for heating repeat the process for the first OFF then the second ON & then the second OFF ( if twice is selected )

Use the DAY button to progress through the week

Then repeat the above process for the hot water slider.

Once all the ON & OFF times for both heat & hot water are set return the AUTO / SET slider to AUTO :)

If it's a 12 hour timer make sure you have set the AM / PM time correctly

Don't know about anyone else but my brain hurts! :)

Yours is,all i wanted to see if there is another one as this either aint working right or don't do what i want.

Getting sorted for the winter for my elderly dad.

But i think i have just solved it,you have a day button mine don't but its the exact same control.

If i did like you said on here when i go to the Hot Water it changes the heating time.

Thanks a lot for you help and i do the same as you do but i see the problem.

Thanks Mark for your help,great chap,mine is below and picture might be a bit big.

Yes Jason - you need a modern programmer / timer installed to gain full control over a 24 hour / 7 day time period - one that has day settings :)

Happy to help you :)

You are right in one way with the economy 7 because we have it they can fit another timer but not needed.

Person came round and said you get hot water through the night (cheap rate) and leave hot water on set to the one

time,5am until 4pm (or what you want ) as we will have hot water in the morning off

the economy 7 and all the gas will do is keep it hot and then you will have a 45L of hot water at the set temp you want it at on your tank,i say that gas came on twice all day and then wasn't on long to keep it at that temp.

Even if we never work off the gas the tank stops hot/warm from 5am until 1pm area.
