Vaillant ashp (my battle with).

[zoothorn]

@-rick- Many thanks again for your suggestions:
 

All taken on board/ redoing the upstairs plasterboard especially etc. Understood. A big job I can't quite plunge into right now, February etc. But food for thought!
 

And @Big Jimbo for the holes / foam idea: this is the most feasable idea, for me, & as I don't neccessarily need these bedrooms warm, only priority is improving the big room below.
 

I'll put a line under this thread, having been a conclusion to my Vaillant battle, now me drifting way off topic.
 

Fantastic help, as per usual.

Been a bit busy today, just looked at the earlier posts. Sorry I clearly got the build up of the upstairs rooms wrong. If it's plasterboard on dabs on dodgy cavity wall then the plasterboard tent point is even more valid.

 

One of the reasons I suggest dealing with those rooms first is if cold air is getting into the structure from there it's going to make heating the downstairs harder. Loads of houses have cold concrete floors and while they may not be the most comfortable they can generally be heated which makes me think that dealing with the floor should be lower down on the priority list until you have the ability to heat better than now.

 

Whatever you do, if the heating system is running off a thermostat located in a warm room or it continues only operating for a few hours a day your house wont be warm unless you do an awful lot of work (bringing the house to modern standards). But, if basic air sealing is done and plasterboard tent possibilities are eliminated then what you have should be able to warm the space if the actually running (ie, the thermostat and timer are all saying 'provide heat'). Can you confirm where the thermostat is? If it needs moving you should start thinking about that and also put some time into working out how to change the schedule.

 

Wish you the best of luck dealing with this.
