Wet or Electric Underfloor Heating - Kitchen

[Haggistrap]

We are about to renovate our kitchen, which will include replacing the concrete floor, with a new insulated concrete floor. It will be dug up to a depth of 300mm and include 75mm of insulation. Currently the house and the kitchen is heated by radiators from an "old" boiler. It's a gravity hot water central heating system, i.e. hot water on or hot water and heating on, no option have just the heating on. (hot water has a valve to turn it on\off when it's at temp) I do not want to alter the boiler or heating system.

In the new kitchen we want to install underfloor heating the size of the room is 7m x 4.3m.

To keep things simple I was just going to fit an electric system, but I have some concerns over the running cost of the electric system.

To install a wet underfloor system, can the feeds from the existing kitchen radiator be used as the feeds for a wet underfloor system? What would I need to make this work? Or would there need to be major changes our current heating etc?

Or will something like this do the job?

For an area that size wet every time - but it needs to be on its own independently controlled zone.
