vaillant ecotec plus 618 water not hot enough

[galerina]

Hi, even though the temp setting is turned up to the max, the hot water is only at about 40 degrees celsius. It definitely used to get a lot hotter.

Any idea what the problem may be before I have to fork out for an engineer. I have read that maybe the flow rate needs to be reduced to get hotter water but like I said, it used to be much hotter. The pressure gauge reads at 12 o' clock, right at the top end of the dark grey zone just before it goes into the red. Could this be the problem as I was told before to keep that needle in the mid section of the dark grey area. If so, how to reduce pressure in the system?

Thanks for any ideas

You're confusing the 618 for a combi, which it's not.

Hi again.

I realise it's not a combi with instant hot water, it's got a tank. The hot water is still a lot cooler than it used to be though.

What's the stat on the hot water tank set to?

Tried turning it up a notch?

Are the radiators cool also?

I guess the rads are a bit cooler as well. The thermostat on the tank itself is set to 60 c. Should I still try turning that up. thanks for answering!

Does the temp display alter on the boiler display when you move the boiler CH thermostat dial? (bottom one)
