24i boiler lpg water gets to hot - Bosch Water Heaters

NO!!! DO YOU HAVE A MONOFLOW ONE PIPE WITH 2 TEES, OR A SINGLE PIPE LOOP GOING IN AND OUT, OR 2 PIPE SUPPLY AND RETUUN SYSTEM ? ZONE VALVES OR SEPERATE CIRCULATORS ? EATHER WAY BOILER WATER NEEDS TO CIRCULATE FROM SUPPLY TO RETURN. JUST FINISH WHAT YOU STARTED.

Hi Steve, I am not a plumber but have done a lot of DIY on my own heating system with Worcester Bosch combi boiler! I believe that you can have the hot water on without the heating system filled, just turn all the settings as for summer use and the thermostat right down so the heating is forced to stay off!

The link is to how to flush a tankless system.
This should be done once a year.

This link is to the manual on the unit.
On my unit, it the hot water is running slow the unit turns off and the hot water goes cold, so for me its run the water on full.

Annie, I don't have experience in this boiler , but I found a link that has some information and numbers to get help. Thought I would pass it on and hope it will be helpful.

your condensation pipe may be frozen get a hairdryer on it or a hot kettle that should sort it thats the whit pipe on the left usualy plastic

Pressure is ok? at 1 bar or above
I think on this one there should be a reset button [red] on the left hand top of the casing - or lower the control panel [ phillips screw on each side] and the button is on the left of the base plate. Press this and try the heating.or hot tap
P.S. if you're on a prepayment meter check you have gas.

Sounds like a mixing issue. Try turning the cold water supply off,then going to the hot water faucet and see if you are still getting a flow of water out of the faucet. If so then there is a mixing problem somewhere.

This is lack of water flow through the diverter valve.

First have you got a good flow from any cold tap? If yes then see below

If I remember there is a pipe carrying cold mains crossing the lower front of the boiler with an in line filter usually clogged. Remove clean & replace
check also any filter in rising mains to boiler

another cause is the diverter valve itself - diaphram inside may be punctured/split

All these machines need 0,8 bar minimum pressure for one.
When significant drop of pressure call qualified repair man.

If this is not your regular work you are at mortal risk.
