Daft Doctor Posted August 10, 2013 Share Posted August 10, 2013 Hi, have tried to get the answer to this from various sources, so thought the sparkys out there might just know. We are having a house built. The land was provided with a supply to the boundary via ERDF, a (monophasic) 12kVA supply was requested when it was done. The builder has passed on the conclusions of a 'thermic study' of the house and a 15kVA supply has been recommended as part of these conclusions. The builder has admitted that this thermic study doesn't take account of any heat which might be provided by a poele à bois, and admits that if we stuck with 12kVA it would only likely be a problem if everything was run to capacity, i.e in the depth of a very cold winter snap.They have rightly said that if a 15kVA supply is provided, it would need to be triphasic, and have quoted around 1,000 euros for an upgraded board, additional wiring, etc. What I am unsure of however is whether the supply currently provided to our boundary would also need to be structurally upgraded, i.e. incurring additional costs with ERDF?If the answer is no, then 1,000 euros might be worth the absolute certainty of no trip-outs, but if there would be additional costs on top, I'd rather just manage with the 12 kVA originally planned and burn more logs on the woodburner. Can anyone help or advise? [:D] Link to comment Share on other sites More sharing options...
