We have a Worcester Bosch combi boiler Greenstar 29CDi Classic LPG. It's 3 years old but I can't be sure how long we've had the problem.
I originally set the tap water temp at 5, then 4, then 3 and it was still uncomfortably hot for my hands. Yesterday I turned it down to minimum (1) and it has made no difference. Turning on 'Eco' just means it takes longer to get to that temp.
Could this be something easy to adjust or does the boiler have a fault?
It was serviced a few weeks ago. The guy commented on the setting but that's all.

The pressure is not brilliant here c. 1.5 bar at the boiler. We're fairly high up and I'm pretty sure it's 1/2" feed from the road. But within limits, the water board say.
There is (was) a 5 year warranty on the boiler and we have a yearly inspection so I'm wondering if I should contact the manufacturer or the service company or just accept it because that's what it's supposed to do. I know there are some knowledgeable PHers in this area.
