You're probably right, mysteryman. Thanks for all your help, anyways! :D

Sorry, it might also be worth mentioning that, when I looked at the Danfoss FHV-R valve specification on their website, it mentioned that this type of valve should not be used in ufh areas exceeding 10m2. Our floor area is 18m2. Even if the builder has cheated and used a 14m2 small area pack...

Thanks again mointainwalker and Norcon. No Uponor Company Control Pack V4 has been fitted. We have previously raised this with the builder, whose response was to send us an out of date (2006) which states that the Uponor small area pack of 14m2 (despite our floor area being 18m2) can "be...

Hi All, First time posting on here, so hope this is clear. As part of our extension we have had underfloor heating installed in the new part of our property. Our builder has installed an Uponor system in a screed floor. The total area of the kitchen and utility room (the areas served by the...
