Is this product suitable for bathrooms?
This can be, but only if the customer is using a floating engineered wood / laminate finish, which is very rare for Bathrooms as they’ll tend to be Tiled or Vinyl floor finishes, both of which cannot be used over this mat.
Can you connect more than one kit to one thermostat?
You can connect multiple mats into a single thermostat, but they cannot be connected or joined directly. You would need to take the cold tail (point in which the UFH mats connect to the controller) back to a Junction Box, which will take multiple connections into it and output them as a single cable, which you would connect into the back of the thermostat. Please be aware that the thermostats for Electric UFH have a 16A limit on the fuse, so if the multiple mats exceed this 16A limit, you’ll need to install and utilise a Contactor of suitable output to ensure the fuse doesn’t blow. You can calculate your output with the following sum : - Watts per SQM x SQM coverage divided by voltage (230) For example, for a 10sqm 150w mat, your calculation would be : 150 x 10 divided by 230 = 6.52A
Can the prowarm protouch E wifi smart electric thermostat be programmed into the Hive system?
The ProTouch Wi-Fi Thermostat only works on it’s own network and isolated from any other controls. Therefore, it cannot be directly linked in to the HIVE system, but it can operate on it’s on Wi-Fi Smartphone App separate from HIVE.
