Hello all. My first post.
I have a Vaillant eco tec boiler in the garage with built in frost stat. There is also a Honeywell frost stat inside the garage wired up to the boiler. The boiler is coming on when the temperature dips but all radiators get very hot and stay on for ages (days) even when temp raises. They eventually do shut off but it's costing a fortune. I think that the plumber may have "fixed" the frost stat when he rewired the heating system in the summer because we didn't have this problem last winter (and it was very cold for weeks on end). Do I need the external frost stat if the boiler has an internal one and if not can I just disconnect it. Many thanks.
