Cold bedroom in new build house

vacheron

If the builder will not budge, Things i would consider (in this order) would be:

1. Check the room for draughts, cold spots, or any damp areas, especailly around the windows.
   
   
2. Turn down the manual (non-TRV valve) in the 3rd floor bedroom. This should heat the room with the thermostat slower and allow more time for your daughters room to get warm.
   
   
3. As the house is a new build the radiators may not have not been correctly balanced (this takes time to do properly). The radiator in your daughters room may be hot to touch at the top, but if the lockshield valve has been closed too much during the initial balancing the return temperatures from her radiator may be too low so the radiator will not be operating at its full efficiency. Conversely the one in the bedroom wit the thermostat may be too far open.
   
   
4. Consider a wireless thermostat which will allow you to move the temperature sensor to any room in the house to obtain a better balance. Easy to fit / remove and no house wiring disturbance necessary.
   
   
5. If your daughters radiator is a single, replace it with a single with fins, if it is a single with fins, swap it for a double. Easy job for any plumber or competent DIY'er. and will significantly increase the heat released into that room.

*edit: Just noticed Trapdoor hit on a lot of these while I was typing!

We did think this, but when mentioned to the developer they said that the NHBC would not have passed the house if that was the case. We would like to check this out but have been told that if we drill any holes to check it out our warranty would be invalidated.

Both wrong and unfortunately what developers say, but are less willing to put in writing. Which is why your concerns have to be in writing. Back to my earlier post and I re-iterate that the developer is going to fob you off - they will have little interest in you because the profits are declared and now somebody ( probably them) has to pay for what is happening.


Bear in mind it is your home so you are at liberty to do as you. A warranty is not going to stop you methodically checking a loft space above your daughters bedroom. A careful pilot drilling and hole cutter could also look at the walls - your choice here.


But ponder laterally. New homes are exceptionally well insulated and draft proofed - if built properly. They require minimal heating. Nobody has seen your degree of exposure, but as a general rule, your cold house suggests something is wrong somewhere. Insulation and drafts has to be part of your search
