Ocean 80 FF Boiler

[kilclare]

Having just bought a one bed flat and had the boiler serviced and commissioned back in April, we are having problems with over heated water in the shower, lack of room thermostat, and now the pressure guage jumping up to three. I have vented this back down but up it goes again.

The boiler is probably 10 years old - time to replace or repair?

The lack of thermostat isn't the boiler's fault, overheated water in the shower may not be either, the mixer should be able to cope easily with hot water.
The pressure problem is either the filling loop valves "letting by" or worse. Disconnect the loop and see if it dribbles. Fairly easy to fix if it's that.

Worse - would be a secondary heat exchanger leaking between the two sides. This fairly undesirable boiler has the said heat exchange in a position which makes it very difficult to remove. I was dismantling one for spares and it was b hard to get out with the thing on a bench! I daresay the part is quite expensive too.
I'd hope it's the filling loop, but start saving for a replacement anyway!

does it go to 3 bar hot or cold?

Thanks both of you for your help - there was a dribble in the loop- you obviously have to be careful that each valve is fully shut off.

I am now left with the overheat problem - the hot water is coming through the taps far too hot, but there only seems to be a temp control for the radiators - where's the control for HW - is it factory set?

On a google search for Ocean FF 80 boiler I got an exploded parts diagram but no list.

I would be grateful for your further help.

there is usually a flow restrictor somewhere (cold feed ) but i would wait for more posts before trying to find it im not up on the make

I've spent a couple of minutes with the MI but I'm none the wiser. There's a filter too which could be part blocked. Call to the manufacturer I think.
