some may of had this for yrs,but all new to me.

Not used to having a thermostat control the heat,im used to a boiler have a set time on/off and thats it.

it seems once the heat goes below the set temp the heating comes on, so if i left a window open etc lowers the room temp etc heatin comes on,not kean on that idea !!

basically, if i have worked the meaning out right.

7.30 am i have set the target temp to 21 degrees C
12.30pm (afternoon) i set it to target temp of 15 (missus is in out in out etc doors open
6pm i have set it target temp of 19
9pm target temp 17.5

does that sound about right ?

current temp in the room is 19-20 degrees c

cheers

Sounds ok.
On mine, 17 would be a bit low at 9pm and it really cools down as the sun goes down. We certainly turn up between 6 and 9.

what would scooby do

Golden rule #1 if you set the temp over 20 then you live in a council house

21 is pretty hot

That looks way too complicated for me !!

our thermostat is in the hall and it sits at about 15 degrees all day.....if I feel chilly I turn it to 20 degrees.....and then it goes back to 15 degrees at night LOL

yup,it is, its like going from a mini 1971 model in boiler terms (our old one) to a 2007 ferrari enzo etc !

What make and model of boiler is it??

We'r ehaving a combi boiler fitted in the next couple of months and that's the type of feature I'm looking for. Currently all we can do is turnt he manual dial and that's it.

So how many temperatures can you set per day, and can you programme it for 7 days i.e. to allow for extra heating when more people are home on weekends?

How do you work that out?

Mines been at 21 all winter, and i dont live in a council house?

What make and model of thermostat is it?? We're looking for a programmable one to replace our 7-day timer one. Does it have 'holiday' or other pre-programmed modes?

Does anyone know if a 'standard' thermostat can be directly replaced by a programmable one, or whether additional wiring is required back to the boiler?

Hanley

We're thinking about getting the Worcester Bosch Greenstar 37Cdi (sounds like a diesel car)

It is programmable so you can set 6 temperature ranges throughout the day and you can set it to a 7 day setting or 5 day weekday setting and differing temperatures for the weekend.

It also has a holiday mode.

You can buy the RF optimiser so no more wires and you can fit it anywhere

We've got all this to look forward to from next week. Our boiler packed up 10 days ago. Got to have a new hot water tank as well. They're only 32 years old, FFS!

Hanley

Why not get a Combi boiler and eliminate the need for hot water tank?

paulr

Our boiler is 25 years old. We are thinking of replacing it, as we understand a new boiler will be more efficient. Not sure wether to go for new condensing boiler, or the combi route. Small house, two occupants.

Alternatively, as we had a new tank 6 years ago, wait for the boiler to pack up.

And where am I supposed to dry my knickers if I don't have an airing cupboard?

Small oil filled tube heater in the bottom of the cupboard.

programmable room stat can be a direct replacement for a standard room stat... its just a switch at the end of the day. we now tend to fit wireless room stats as standard.

As for the boiler i would always tend to fit Vaillant boilers, there about £60 more on average but i never do breakdowns on them ( out of all the boilers that were called to repair). dont get an Alpha, Biasi, or vokera..... there all crap.

Do you have any experience of the Worcester Bosch series??

the boiler is a vaillant 831 ecotech plus model and the thermostat is a wireless honeywell CM921

seem to have the nack of it now

I have the Worcester Greenstar 30Cdi and also fitted a RF Optimiser stat. Been fitted about 15 months now and works great. Got it set to 7 degrees o/night, then comes on about 645am at 21 degrees until 900am. 15 degrees all day (missis turns it up manually if needed) then back to 21 degrees from 1700 till 2230. Never change it from that. The misses will never put a jumper/top on, just cranks the heating up. Good job the Worcester's good on gas.

The good thing about the Worcester Optimiser thermostat, is that if say at 645am when the heating is due to come on (set at 21), and the room temp is already 20 degrees, it will not fire up to save gas, just to rise the temp 1 degree. It also learns warm up times for the room, so can fire later/earlier to suit. Very clever.

The worcester bosch boilers are pretty good on the whole, ive just had a few with heat exchanger problems. as opposed to fitting hundreds of vaillants and only ever having had one with a faulty PCB. if i had gas where i live then ild be having a vaillant, still wouldnt go for the vaillant wireless room stat though as its just to bloody complicated to use.

the boiler we had removed was a cracking boiler, vallaint vcw 242 the one with titanium heat exchanger etc.

As a colleague found out, what happens when the combi goes wrong? Your left with no hot water at all. Even worse with no electric shower.

Least with a tank you can flick the immersion heater on and get hot water.
