Vaillant ashp (my battle with).

So I'm not clear on whether I could do this, even if I had 30m of specific cable & a day's work drilling through a wall & a ceiling crawling around my attic to re-site this thing to my cold kitchen downstairs.

 

I think @Nickfromwales's suggestion to get a wireless one, that has a reciever that is wired in to your existing may be the easier option. I do think either way though it would be better done by someone else. But I don't know Valliant specifically or whats involved there so will leave this to others.

I asked him Rick. It is not easy. It's 6-steps then out again in 4-steps, to put it to ON, on this little thermostat-controller box.

 

If there was a switch on the box, saying Heating ON.. I mean easy, I flick a switch.

I can see the same 6-steps/4-steps & out, to also set the timetr (& also whilst there within the menu, to turn heating to AUTO.. although I can't remembe4 what AUTO even means)..

 

But I thought you didn't want me to set the timer?! Why would you ask me to ask this, to him? (I mean I did, but god only knows why I'm asking it).
 

I'm now getting further confused.

@-rick- Here, you say at the end..

 

"Now I have switched to keeping the place at a relatively constant temperature (with a setback) it's much more comfortable and burns less gas than heating from cold every morning".

 

I understand the principle you suggest of 'having the system on' in a continuous way. But here you refer to your continual way "with a setback". The chap told today -& this made my head explode- the following: "You cannot have the heating on, & have a setback setting: the setback setting is for timed blocks".

 

These timed blocks though (I assume the word 'timer' you use ,relates to my current "bad way to do it" setting), is the very setting, you are steering me away from.

Tbh this engineer wasn't the ideal chap. Not too happy being here, short with answers, quite impatient wanting to go asap & coughing continually with a cold.. & I had no choice but cosy up next to him showing me how xyz at the little controller-thermostat box. With a visit to my frail elderly parents soon. Argh!!

 

Why can't anyone who visits like so, just put a fkn face mask on?!! I wasn't too happy as you can appreciate, but I did my best nevertheless.

Ah this is confusing isn't it!

 

Let me try again:

 

The thing we want to avoid is where the heating is full blast for a few hours a day and then entirely off for the rest of the time.

 

We want the system to be on and able to provide heat at any time day or night (if the thermostat says it needs heat).

 

However, it is ok to have the temperature set point vary by time as long as by a small amount. ie it's ok to have the setpoint be 20C in the daytime and 18C at nighttime and use the timer to do this

 

It would not be ok to have 20C in the day and 10C at night as that is too big a difference and it is effectively the same as just turning the system off overnight.

 

Given you have struggled with the system it seems best to keep things as easy as possible. The easiest possible way is to keep the system on 24x7 and use a TRV in your bedroom to lower the temp in your bedroom vs other rooms. Setting up the timer with two different temperatures is the other option but more complicated to do.

 

Edit: You may well need a TRV in the bedroom anyway even if you use the timer for setback because it is better insulated than the rest of the property it is likely to warm up first and end up hotter than the others spaces without a TRV

I can't understand this though Rick. How can a wireless thermostat work: I mean thete's no super-convenient wireless transmitter from the interface box (where the controller-thermostat box's canle originates from).. to transmit to a wireless device.

When you buy it you get two boxes.

 

1. The thermostat that you can put wherever

2. A reciever box that is wired into the heatpump controller.

@-rick-

 

I now am confused by setpoint. And setback. As I haven't encountered 'setpoint' terminology, until afaict, today when it's first being used by yourself.

 

I seriously need a break. I am really completely & absolutely baffled with it all now.

 

I'll come back later. Many thanks though, Zoot

Ah I am sorry.

 

I'm using 'setpoint' to mean the temperature you set the system to deliver.

 

'setback' is used to mean a lower temperature than the one you normally want.

 

So you might set 'setpoint' to 20C for daytime and 'setback' to 18C for nighttime.

No problem.

Poor old Zoot. He has not managed to get himself any further forward. I think he is destined to stay cold and damp forever more.

 

He currently spends £60 per month on his energy bills.

 

Regardless of the well meaning posts on here, we all have to agree that tweeking his system might bring him some small benifits, but ultimately not change a great deal in the way of comfort.

 

The only way that the current situation is going to get better, is by either spending a considerable amount of money on upgrading the house, or considerably more money on energy costs.

 

I don't believe he will want to spend more money on energy costs. he, like me, is obviously a bit of a dinosaur. (I ain't paying £4 for a coffee, when i used to spend 20pence on One 40 odd years ago)

 

I personally don't think that a bit of tweeking of the system, is going to make the Zoot toasty warm. I think that perhaps tweeking the system, and accepting considerably higher bills, is something that the Zoot is either going to have to accept, or remain cold.

That is up to zoot. We have said repeatedly that if he wants to be warmer he will have to spend more, but it is also clear that a lot of what he already spends is wasted.

 

My goal in helping is to get the system to the point where zoot has a choice.

 

How much to spend is variable. Every 1C of internal temperature will cost money. For his current £60 per month if applied wisely his internal temp could be maintained at a level where his breath is not visible. Warm and cosy no, but its still an improvement. Spending more can raise the temperature and once the system is functioning correctly what temperature and how much to spend is completely down to zoot.
