OK, I have the Vokera Linea 28 combi boiler. This supplies my hot water as when required, and also the radiators. Each radiator has a knob at the bottom, with numbers ranging frm 1-5, 1 being cooler, 5 being hot. However, there is no thermostat as such. Yes I could set all the radiators to 4, but I want to be abe to specify a temp and the boiler come on and off when it cools/heat. The only digital thing the boiler has at the moment is a 7day programmable timer, which does a good job and is easy to use. Is there a thermostat which can be retrofitted to this boiler. I would get a electrician/gas fitter? to install the boiler side of things. I would prefer wireless, with maybe a remote so i can override things from my bed. Any ideas???
