Hi
We have just moved into our new house and it has an Ariston Eurocombi(its either an A/23 or A/27 MFFI)
We had a problem with the hot water not staying constantly hot.
I have read through the manuals and checked online and thought I would try the adjusting the flow rate.I have managed to get the HW to stabilise for a nice hot bath but the flow rate is now 6 litres a minute.
I have a few questions
1-I need to get a thermometer to be more precise but am I correct in assuming that where it says 'Flow rate at /\T 35c' means it will raise the water temp of xlitres 35c?
2-If it turns out that the boiler is OK and I am asking it to do too much(my partner has a rare condition and subsequently a nice hot bath is one of the few things that eases the pain)will running it at this reduced flow cause any damage?
3-I have read a few posts regarding sludge in the secondary heat exchanger,is it an easy job to get it out and clean(I am an electrical engineer) so I am confident in stripping it down unless it involves breaking into anything to do with the gas.
4- This is totally unrelated but the CH system has no wall stat, but each radiator has a thermostatic valve.Does the boiler shut down automatically when there is no demand for the rads or continually cycle.Is it worth installing a room stat to save energy?
Thanks
Mike
