SOURCE: Combi Boiler - Hot water pressure low

I have a 1 bed flat, above an old pub. I have a combi boiler but my water pressure is ridiculous. The shower water runns down the shower head. I'v been told that the cold water feed to the building is split to two boilers, one to the pub and one to me. Im thinking of installing a shower pump in between the boiler and the shower. will this work as my friend says he has done this and it sorted his problem out. I'v looked it up on the net and everything says this does not work. Help please.....

My ideal logic combi 30+ is saying ignition lockout and my radiatiors arent heating up as well as my water not turning hot. How can i fix this please?


Lockout is a safety feature. Usually a latching condition and needs to be investigated rather than blindly reset. (The Combi has a bit more intelligence.) With the ignition locked out, you can't hi-fire the boiler, so no hot water of either type. The 'L' should also show a code number - check your user manual (google) for more guidance.

I've had a lockout on a non-combi: it was caused by lack of circulation of central heating water through the boiler.... The system boiled and the trip tripped. The pump WAS running, but wear in a valve actuator resulted in the valve feedback saying valve open while it was physically shut.

I've got a Worcester Bosch boiler had a leak In the pipe On the landing so a friend emptied the boiler an I fixed the pipe but I don't know how to refill the boiler


Can you get the manual online? You have the Manufacturer info so you probably have the model number too. I found a manual on Manuals.com for my boiler so they may have yours too which will hopefully have some information on filling boiler although I realize each installation is somewhat different but that's why it's difficult to answer you question. Usually there is a manual pressure valve that regulates the water pressure in the boiler which is usually pretty low...like less than 20 lbs. The manual should tell you the pressure as well. But this pressure valve has a flip handle that comes off the cold water line to the boiler to do just what you want to do...refill it with water. When refilling the boiler (if you find the valve, you may have to purge the air out of the lines which there is a whole other process for. But you shouldn't allow cold water into a hot boiler...it could crack it when the cold water hits the hot cast iron. So make sure the boiler is cool when filling it up.
Now go try to find that manual!

Wickes 102 combi boiler constantly loosing water pressure


It sounds like your thermostat could be the problem. Have you noticed the boiler cutting off at all, or does it run continuously until it goes out on low water?

You stated, "when boiler is on", so I am wondering how you get the boiler on. If your boiler is controlled by a thermostat, you need to check it for a cold draft possibly from behind the thermostat in the wall where the wires come through. The thermostat should never be on an outside wall. The thermostat could be defective.

An aquastat can also control your boiler. If you have an aquastat, check the setting, typically 175 - 180 degrees. You should also have a "high limit" which should be set at 210 - 220. Some people run that high side limit higher; not a good idea - defeats the purpose. If the aquastat is set too high, the boiler will operate too hot and the problem you have will occur.

"pressure rises and pressure relief valve opens" This could mean that your pressure switch is prematurely venting. Check boiler temperature to see exactly at what temperature the T&P valve purges. If it blows off below the high side setting, either adjust or replace. The T&P valves are usually not adjustable. That blow off temperature is stamped on the head of the valve. So, if it discharges too soon, replace it.

Have you actually seen evidence thgat the T&P valve is opening? You may have a bad bladder in your expansion tank and your system may have air in it. Your boiler should have 12 psi when cold and 20 - 22 psi when operating. Check your boiler pressure guage.

"
this eventually drops below the minimum operating pressure" Technically, there is set point for a NO MINIMUM OPERATING PRESSURE. That is a function of the amount of water in the boiler. If the T&P is blowing off, it will vent water from the boiler and the boiler pressure will go down. There is a minimum operating TEMPERATURE.

Your boiler could be low on water. You will have to manually fill the boiler. Be careful of thermal shock to the boiler. Feel the piping, and fill only when the circulator is running. Make sure the water is not going directly into the boiler. The supply water should go into the circulating supply side which feeds the radiators, radiant floor, or base board circuits.

All this will adversely affect your hot water. The heat exchanger for the potable hot water may have scale build up in it. Using the hot water keeps the boiler running, and a scaled heat exchanger will give you cooler hot water and the boiler keeps running. If this is a problem, you will need to replace the heat exchanger. A better idea is to not use the boiler for your domestic hot water. Why run the boiler in the summer?

Baxi boiler 80E low pressure on boiler how to fix it?


Silver flex hose may be the (correct) filling loop. There may be a valve at each end of it, maybe just one at one end.
Open the single valve slowly and LISTEN for the sound of water entering the system, and LOOK for signs of the pressure gauge rising.
On the dual valve version open the first, then open the second slowly as above. Close both valves when pressure is adequate. Adequate is determined by the specifics of your system, but note that more pressure DOES NOT mean better showers, etc.
It should only take a few seconds to top-up, any longer indicates a significant loss of fluid from the system.

I have an ideal standard he30 boiler instaled about 6 weeks ago. the boiler keeps losing presure about half a bar every 2 days if i dont top it up it will trip the fuse on the fuse board acording to the...


All the combis I've come across merely fail to fire if the pressure is not up. not only do they not fire, nothing else works including the pump and in any event the pump should not overheat just on low pressure.
water loss - try turning off the valves on the flow & return pipes [3/4 inch ones] 1 valve per pipe . This will isolate the rest of the system - rads etc Note pressure over a time period. In this mode the hot water circuit will still work but do NOT use the heating circuit
1/2 bar over 2 days is not serious but it should be found
Once you have either mended the leak in the rest of the system or found there is not one, insist on a replacement boiler
In any event having looked at the reasons given for the fuse blowing, I would definitely get a replacement.
These problems should not happen on a new boiler
I list Worcester.-Ariston-GlowWorm-Ideal- and many others who would confirm this
