My mates boiler, heating is fine, when hot tap is opened, it runs hot at the start, then tends to go cooler, but stays warm, to get it hot, he turns the taps down, and it gets better.
The weather is a lot better, not as cold. The boiler display is as normal, would i start with the actuater on the diverter valve? thanks.
