So vsmart my only option?You’ll need to use Vaillants own control system.
So that the boiler knows wether it is doing heating or hot water.

Yep you’ll also need the vr66(I think it’s called) wiring centre.So vsmart my only option?

Get a boiler with OpenTherm and and a Opentherm thermostat. That will modulate the burner to the room setpoint.A modulating thermostat will give far better returns than simple WC. Make sure that whatever boiler you chose can differentiate between the hot water and heating functions as you will need a separate flow temp when reheating the cylinder

If you have a kickspace heater, weather compensation and room temp burner modulation is not what you need.

Agreed, the kick space heaters I bought yesterday specifically tabulate the various heat outputs at different flow temperatures so they will clearly work well with weather compensation.Twaddle
Will They? Look again. Kickspaces work well on high temperatures. On lower temperatures the output will drop off. A WC may take it below a suitable temperature and blow coolish air. You have to be very careful how you set the slope on WC. To accommodate the kickspace `properly` you will compromise the efficient operation of the WC, to the point it not be worth having one. With a kickspace it is best to have a boiler that gives out a constant boiler temperature with rad valves trimming each room.Agreed, the kick space heaters I bought yesterday specifically tabulate the various heat outputs at different flow temperatures so they will clearly work well with weather compensation.
Our resident Numpty doesn't have a clue what it means. He is fun.Hard-On also has no idea how OpenTherm works.
So in other words exactly the same as normal radiators. The heat output in both is directly proportional to the temperature difference.Will They? Look again. Kickspaces work well on high temperatures. On lower temperatures the output will drop off.
