But hot-water heating systems are controlled by a different set of devices, and they have additional components that need tending. The controls include a combination gauge, often called an altitude gauge, that lets you keep an eye on both water temperature and pressure and lets you know when the boiler needs water or is malfunctioning.
That done he left and topped the boiler back up to 1bar water pressure. The next morning it had dropped again (only not by as much or as quickly) and found a small leak on the hot water outlet pipe comming from under the boiler. He tightened it up and so far the pressure has been ok. But we still have a problem.
I was reading about 13-14psi on the new gauge while the "Altitude" gauges were reading around 30-35, and this was while the boiler was warm. Good! This put the whole situation into a much better perspective. Those "Altitude" gauges are most likely reading pressure in psi * 2.33 = feet of water column.
5. Low Boiler Pressure. Checking the pressure of your boiler couldn't be simpler, just take a look at the built-in pressure gauge. If you find that the needle is below 1, then there might be an issue with low boiler pressure and your central heating system won't function properly.. There a number of reasons why this may be happening:
Oil-fueled boilers and heating systems are popular in areas where there isn't ready access to natural gas. They also allow the homeowner to use renewable fuels and some companies are even offering mixes of heating oil and biodiesel, which produces less pollution than heating oil alone.
Heating boiler gauges: this article describes the combination pressure & temperature gauge found on most hydronic (hot water) heating systems. The boiler gauge gives helpful temperature or pressure readings that tell us if the boiler is operating normally. The same pressure and temperature readings at a boiler can help diagnose problems such as TP valve leaks, cold radiators, and even boiler

Water boils at 212 at atmospheric pressure and the steam coming off of it is 212 also. If you go to the top of a mountain the pressure decreases and so does the boiling point of water. In a boiler pressure vessel as the water boils and steam is created this increases the pressure in the vessel which increases the boiling point.
Boilers. Boilers are special-purpose water heaters. While furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. The cooler water then returns to the boiler to be reheated. Hot water systems are often called hydronic

Re: Water pressure too high after using hot water if it's only on the hot side, you have a check valve on the heater or those heat saver nipples with little marbles/ junk you need to install an expansion tank and that should help. if it's on both the hot and cold, then there is an issue with your regulator and the bypass for thermal expansion is not working. or there is a check valve on the
Your boiler must be at the correct pressure for the hot water to circulate properly between the radiators, especially if they are on different floors.Generally, the ideal pressure is between 1 and 2 bars, but this may vary from boiler to boiler.Ask your heating engineer. Check the pressure gauge. A quick look at the pressure gauge is enough to check your boiler's pressure.
High-Altitude Adjustment For elevations above 2000 ft, the Btu input should be reduced (derated) 4 percent for each 1000 ft above sea level. This adjustment is required because of the increase in air volume at higher elevations. Air expands at approximately 4 percent per 1000 ft of elevation. At elevations above 2000 ft, the volume

The pressure gauge is at 1.5 and "seems" like boiler is working fine, but no hot water or heat in radiators. The "low pressure light is on, I have tried a reset but no good. There is a White plastic "valve"( I think) marked "combi loop" which I turned and which got the pressure up a bit, but still "low system pressure" light is on

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
