New Condensing Boiler - Lower Central Heating Temperature

[oakenlivery]

Please calm down everyone!

If you read my earlier response you will see that I have taken all of your useful advice and have turned the TRV's to their maximum.

The room is warm but not as warm as I would have expected i.e 23 degrees at present whereas the main thermostat is set to a maximum of 26 degrees.

I am now turning the Boiler Stat to maximum to see if this levels things up.

are they hot to the touch?

 

[oakenlivery]

Yes they are warm to the touch, although not extremely hot.

 

[Gasman77]

If they are all roughly the same temp in the house, then its the boiler stat too low. If some are raging hot, others cool , it needs to be balanced

 

[oakenlivery]

Thank you Gasman77. I will wait now to see how turning up the Boiler stat effects things.

 

[Gasman77]

Good luck

The main thermostat, a Drayton RF wireless type. is in the entrance hall.

Because you have a thermostat fitted you need to turn your boiler thermostat to max. Let the Drayton control the temp.

Then try turning your trv's to max.

Thank you Gasman77 & landyandy. I believe you are both correct as I am beginning to see a result. Things are beginning to heat up around here.

It's disappointing that the installer didn't make this clear when he fitted the system.

Another satisfied customer. Now if you could post your address so I can send you my invoice ..........

It should be set to max if you have a room stat.

A condensing boiler should most certainly not be set to max.

 

[bengasman]

Have you checked the rads for cold spots along the bottom, especially equidistant from the valves?
Did the installer flush the system properly?
Can you measure the temperature of the rads?

I disagree, it will only go to max if the room stat is also turned to max, if its turned lower than the room stat whats the point of having other controls.

I bleed them regularly and ensure that the boiler pressure is maintained at 1.5bar pressure.

Why do you need to bleed the radiators?

The boiler stat determines the temperature of the boiler regardless or the roomstat setting.

Vaillant Ecotecs instructions show to max the boiler if temp below +5 or a room stat is fitted.
