I was looking at these, but ultimately its not going to save me any money or add any features as we have the heating set to 16 hours all day every day

Excuse the silly questions.
With two zones, does this mean we'll need two Heat Links? Where do these go - where the TP9000 is? The TP5000 Si seems to be battery powered.
Wiring - I've got the wiring diagrams as above however not really sure how these relate to the Nest wiring? The compatibility tool talks about lettered wiring.
Assuming we can figure out the wiring, is this a straight swap? I don't mind giving it a go myself but have no issue in getting a Pro in instead!
Edit: May have been looking at the wrong guide for Nest. I've found this one (Page 11) which appears to be similar wiring to mine.

Gammawolf;30487063 said:I do leave for the daily grind mon-fri, but there are always people in my house so theres never a reason to turn it off during the day or have features to turn it on remotely etc. Saying that it doesn't break the bank though, this winter we've averaged about 80Kwh a day (£2.20) in gas for a fairly large house of about 170sqm. Thats with a hot water tank on 24/7 and a 15 year old non condensing boiler with an efficiency rating of 74%.
Interestingly though, we used to have it on at 6am-8am, 12pm-1pm and 5pm-10pm. I did a few tests over several weeks across similar weather conditions and running it at a solid 6am-10pm (16 hours) hardly increased the costs at all (about 7 or 8% during the winter).

VaderDSL;30487245 said:Nah, Barratt, but it uses identical setup with the two zone master bedroom/utility and then rest of the house.
Gammawolf;30487258 said:We don't need that much hot water, but its a convenience vs cost thing. As theres generally people in the house all the time, dishes could be done throughout the day, i take my shower at 8am, others might be later at 9 or 10. Weekends i'm a little lazy and might not have a shower until just before lunch etc so its a bit sporadic.
I did a 24/7 usage test and extrapolated the usage which equated to about £12 a month to keep the tank hot 24/7 and included a normal amount of cooking and two showers. So for the convenience of always having hot water i'm alright with paying a few quid a month for the constant heat loss. In the the winter the heat losses from the tank just heat the house anyway

heating runs for 5/6 hours a day on a temperature of 21/22C - that seems to make the home cosy for us.
anyone got any tips on setting this thing up to be more cost effective!?#
psd99;30489355 said:hey guys
we got a nest in our home
system is new
I turn the hot water on for 1 hour in the morning
1 in the evening seems to do the trick

If it's on only when you need it, and at the minimum comfortable temperature, there is not much more you can do without being colder or spending money on better insulation, more efficient boiler, etc.
Psycho Sonny;30489444 said:21-22 seems high. Mine is set to 16 for when i wake up in the morning and 18-20 for when im at home in the evening.
How well is your house insulated?
Keep blinds, curtains (heavier the better) shutters, etc closed in the evenings.
Keep doors closed around the house.
Turn trvs in rooms that you don't use down slightly. Not fully but slightly.
Get more loft insulation.
Change your energy supplier to the cheapest on the market using moneysavingexpert website and pay by direct debit monthly to get the best rates.
Im in a large 3 bed detached with an attached single garage which has been built on top of so upstairs of my home is larger than downstairs. My gas bill has been building up due to me living in scotland and it being much colder but my monthly breakdown for the past few months is £39, £48, £60 and £73. This months prediction is £59 but i reckon it will be less due to me not being in as much.
Where you live matters a lot as a house in iceland is going to be more expensive to heat than those in africa.
If you have done all of the above then the only thing you can do is move into a newer home with lower ceilings, better insulation and more efficient boiler, etc.
My house was built circa 97-99, this makes a difference too. Newer homes are far more efficiebt due to regulations changing every 3-6 years
Psycho Sonny;30487284 said:fair enough but you could save yourself £20 a month and still have hot water on demand all day long just by keeping the tank well insulated and having it on for say 1 hour in the morning an hour around lunch time and then another hour in the evening. i say £20 as you saved £12 using your previous timings and even that looks like too much IMO.
my wife has long showers and we never run out. she also wastes a lot of hot water doing dishes, etc where she just leaves it running. Same when she has a shower she will turn the shower on 2 minutes before she jumps in just to clear out all the cold water even though it only takes 10 seconds to do so.

Thank you for contacting us with your query.
For a multi-zone system like yours, you would require three Nest Learning Thermostats. They would not be wired to each other, but connected to a controller, called the Heat Link, located next to your boiler or switch valves. This is included in the purchase of the product. There would be three Heat Links, as one Heat Link cannot control multiple Nest Learning Thermostats.
