How to top up pressure in Vokera boiler | DIYnot Forums

Hi Pressure is at 0 and no heating or hot water but I'm not sure what valve(s) to turn to top up. There is a filling loop so from looking online I'm thinking it might be this ( picture 2) but there is also these 2 valves attached to the boiler ( picture 1) which of these do I need to turn to increase the pressure?

Increasing the Energy Efficiency of Boiler and Heater

Boiler water is tested daily in small, low-pressure boiler plants and every hour in large, high-pressure plants. The water treatment and testing program is critical to ensuring the maximum efficiency and reliable operation of any boiler plant.

How To Increase Water Pressure In Your Shower

The higher the head is, the greater your water pressure. Find out about water pressure in your area . Traditionally, British water systems are connected to a cold water storage tank which is kept in the loft. These are known as "gravity fed systems". They are low pressure, and rely on the height of the tank to provide water flow pressure for

Common Boiler Problems, Part 1: Low Water Conditions

The only thing that allows a boiler to withstand these furnace temperatures is the presence of water in or around (depending on whether the boiler is a fire tube or a water tube design) the pressure parts at all times that a fire is present. Low water conditions will literally melt the steel pressure parts.

Basic Steam Theory - Steam Pressure

As the pressure on the surface of the water increases it has the effect of increasing the temperature at which the water boils. While at atmospheric pressure (101.3 kPa) water boils when it reaches the temperature of 100 deg.C. we find that at a pressure of, for example, 690 kPa the boiling point has gone up to 169.95 deg.C.

Boiler Pressure Too High? 4 Fixes to Reduce Boiler Pressure

#4 - Boiler Pressure Rises (Even When Heating/Hot Water Isn't on) The final possibility is that the filling loop (the device used to increase boiler pressure) isn't full turned off. If the valve is stuck partially open (or hasn't been closed fully), that's going to constantly leak small amounts of water into the system.

Combi Boiler increasing in pressure | Screwfix Community Forum

If it is the expansion vestal then the symptom will be over pressurization when the heating is on, the expansion vestal is just a space containing air in which the water can expand into whilst its being heated (water volume will increase with temperature). usually if this is the case the pressure relief valve will drip water out at a high pressure and so when the heating goes off and the

How to increase shower water pressure?

Low Shower Water Pressure with a Combi Boiler. If a combi boiler is struggling to provide the water pressure you want for your shower, then it's worth replacing your shower with an electric shower. Not reliant on your boilers ability to provide hot water, electric showers never run out of hot water.


Water pressure readings are a great way to monitor the health of your plumbing system. Sudden changes in water pressure could be a sign of a serious plumbing problem. Decreases in water pressure and flow could indicate a serious blockage somewhere in your piping.

How to Fix Rising Boiler Pressure |

Too much water in the expansion tank and too little air may also cause pressure to rise frequently. If the bottom of the tank does not feel hotter than the top, it indicates an excessive amount of water. You need to drain this water from the tank. To do so, first turn the boiler off. Then close the water shutoff valve and allow the system to cool.

My hot water boiler keeps increasing pressure when it runs.

My hotwater boiler keeps increasing pressure when it runs. Normal pressure is 12psi but it has risen to as high as 40psi though the max pressure is indicated as 30psi on the gauge. I rcently replaced the flow control value which I set to the normal 12psi prior to use of the heater. The house is dual zoned and the problem occurs in bith zones.

How to increase boiler pressure | Viessmann

It is not unusual for your combi boiler's pressure to increase when the heating is on or the hot water is running, but the pressure should generally not increase by more than 0.5 - 1 bar when there is demand on the system. The reason that the pressure gauge jump ups is that the water inside your boiler expands as it heats up. Your boiler is designed to handle these rapid jumps in pressure
