Vaillant combi boiler temperature settings

But, and it is a big but, the boiler is not running flat out. I am running on average at 60 with maximum output at I understand about draughty house etc etc, but it was draughty with previous boiler?
I vaillant combi boiler temperature settings worried it is all to do with set up of boiler. British Gas have installed it "straight out of box " and intimated that Vaillant know best with "factory settings".
I realise that you clearly stated you are running your new boiler at 60c, but although with a brand new vaillant combi boiler temperature settings system this would be good, a new boiler fitted to old rads may need the flow temp raised a bit. This is because new rads would have been sized to heat the room with a lower flow temp, but your rads still need the higher temp to do that efficiently.
Try running your system at 65c, or even maybe at 70c. This is still low enough to let the boiler condense. The hotter water in the system will let the vaillant combi boiler temperature settings heat up quicker, thereby letting any external controls shut off, therefore shutting the boiler off and saving you some gas. Thanks Dave, I actually understand that!! So instead of turning the boiler down to reduce consumption the reverse could be more effective? Should I not worry about all vaillant combi boiler temperature settings program options?
I have made the couple you mentioned earlier. Thanks for your help, really appreciated. As a learned gentleman Heatmanuk reminded me yesterday, Convection doesn't start until the radiators are at 60c.
Thu Feb vaillant combi boiler temperature settings, 1: I live in the south west so we do not have extreme cold weather. In the past, with the old boiler, a setting of 7 when the outside temperature was 4 or 5 degrees C would keep the house pleasant.
With the new boiler a setting of 65 or 70 vaillant combi boiler temperature settings to do the job. With the temp today outside at 10C a boiler setting of 60 is okay and to answer your question at that setting the readings are D40 59C and D41 54C. To answer your other question re TRV's. Vaillant combi boiler temperature settings operate them incorrectly but in common with the majority I believe. Because the rooms are large and take some heating, I leave them open to max and the old boiler just about coped, as the weather got milder I would turn the boiler down.
But as you can gather my vaillant combi boiler temperature settings is that the new is costing more to run and not less, which is not what I was expecting!! Thu Feb 03, 6: Thu Feb 03, 7: Hot air will always rise, but you won't get circulation within the space. Many years ago I raised the question over LST radiators, saying why not just have a low temperature circuit, instead of fancy covers on the normal rads, I was told it wouldn't work and why but I can't remember exactly what happens, or not as the case maybe.
Perhaps an e to the link you posted. Thu Feb 03, 8: Thu Feb 03, 9: Vaillant boiler help please! Vaillant Ecopro vaillant combi boiler temperature settings Wont come on Forum: No hot water - Vaillant boiler Forum: Page 2 of Previous topic Next topic.
As a learned gentleman Heatmanuk reminded me yesterday, Convection doesn't start until the radiators are at 60c, As I hinted yesterday the boiler parameters for the heating should be turned right down to try and match the load. You need at least 70c coming out of the boiler. This is because the output of a radiator varies according to the water temperature; it is not like an electric fire. A "1kw" rad only produces 1kW when the average water temperature is 70C. The output of the is 24kW for central heating and 31kW for hot water.
It is designed to run with a lower average temperature than the VCW, so rad outputs may be less. You say you have the TRVs set to max.
TRVs keep the valve fully open until they reach the required temperature, when they close down just enough to maintain the vaillant combi boiler temperature settings temperature. So setting the TRV to max only changes the required temperature. It will not make the room get any hotter if the rads are not producing enough heat. Did you need the TRVs on max and was the house warm enough when you had the old boiler? What are your flow d. For this message the author D Hailsham has received gratitude: Never heard that one!
Convection currents Dave, must be something in google I would have thought. To get air circulation, you need a heat source to start vaillant combi boiler temperature settings going radiator below 60c the rad will just get hot but not circulate the air around the room.
Research for you Dave. I understand how convection works; it was the magic figure of 60c which I was querying. I did some research after I posted my original query and found this: Convective air flow -radiator. It would appear that the air flow is related to the difference between room and radiator temperature, but there is nothing to say that there is no convection below 60C.
It may be that it is not very much In everday use this probably would be nearer to 15c. Try balancing the system using the locksheild valves on each rad. The furthest away vaillant combi boiler temperature settings open fully then close them more as you get near the boiler. This is just vaillant combi boiler temperature settings very basic way to balance, but copes with most households. You need to rate the boiler down so it is working harder. For this message the author thescruff has received gratitude: Can't agree with that, boilers condense more when they are just 'ticking over'.
A D40 of 59C is expected if you have set the boiler to 60, but a D41 of 54C suggests that the pump speed is too high. Though this will depend on the outside temperature and the required inside temperature.
It does sound as if you rads may be undersized. You should use Boiler Size Calculator to find out what the heating requirement is for your house - deduct 2kw from the final result.
The use Stelrad Elite Catalogue to find the output of your radiators. Provided the rad output totals more than the heating requirement you will be OK. That's like saying a car is more economical vaillant combi boiler temperature settings 60 up the Mway in second gear. The boiler is at least twice the size it needs to be in the htg mode, the nearer you can rate it down to the required load the cheaper it will be to run.

I live in rented accomodation, I have a very nice landlord but he lives abroad so he can only help so much Taking one shower a day ten minutesusing the gas cooker only once every other day for half an hour!!
This year same story but my thermostat is set to 18 degrees celsius, hoping I would save some money!!! I have set the radiator flow temperature to the maximum allowed which is 75degrees by turning the round knob to the right fully, this is the setting vaillant combi boiler temperature settings is recommended by vaillant in the owner's instruction book!
I have contacted my landlord via email, he's been understanding, he said he will pay for the vaillant yearly service plan in the next week, but he was suggesting lowering the radiator temperature to 65 and making heating come on at 3: When the rooms are cold are the rads actually very hot to touch? If so they are undersized or there isn't enough of them!
A couple of quid makes a real difference. Fri Dec 03, 2: With any luck one of the guys will post a link to an online rad calculator you can use this to show your landlord what size rads you should have. Insulation sounds like the biggest problem or lack of as the case may be, thick curtains may help a bit. Check, vaillant combi boiler temperature settings only paying for your flat and not any communal radiators, in landings and entrance halls, stairwell etc.
Given the boiler is working properly your radiators are too hot to touch then the heat being put out by them is 'disappearing' and the lack of double-glazing is but one cause. Basically, you're heating the outside world.
What you could do is turn the boiler down, and have it on longer, and try it for a month, you should be able to make a log of the meter reading now and for the vaillant combi boiler temperature settings month on a daily basis. Sorry to say that there is no such thing as a 'cheap' electric heater. They are far more expensive than gas heating and you'd be better off spending the money on the gas to keep the boiler going. Fri Dec 03, 3: Is that a shared bill then You wouldn't heat a 4 bed house for that, even if the place was super well lagged, unless they're fiddling the meter.
Fri Dec 03, 4: Do a couple of days as is, and record the daily use at the meter, then try it for a while keeping a record with the new settings.

Hi, thank you, yes the radiators do get very hot to touch, I could not keep my hand on them for example It seems I will be 'stuck' with this problem then, unless I convince the landlord to install one more radiator!
Thank you 'thescruff' I life in a ground floor 'conversion flat' not in a block of flats, so it's only me downstairs vaillant combi boiler temperature settings the flat upstairs, no communal entrance hall or stairwells. I was thinking of buying an electric 'storage heater' or something like that anyway or the cheapest electric heater to run and put it at the end of the kitchen near back door where I feel most of the cold, if I heat that end up a bit I might help the situation a bit?
