I recently had a new WB 30CDi System boiler installed as part of a solar HW installation, along with an unvented thermal store. Everything was installed by suitably qualified personnel. But I am not 100% sure about the installation.
The boiler is controlled by the main power feed, i.e. when the thermostat asks for heat it turns the power to the boiler on, and the reverse when the thermostat has reached the required temperature. I don't understand how the boiler can possibly be functioning at is optimum if it has to go through it's self test routine whenever the stat kicks in.
Does anyone have any thoughts on the subject.
