Why does the pressure rise to over 3bar when the central heating is in operation ?


3 Bar = 43.5 PSI When you heat water it always expands increasing pressure.
In a closed vessel volume can increase by 2-3%. Either expansion tanks allow for this and PSI is maintain or without an expansion outlet the PSI will increase in proportion to heat supplied.
Is this a low temp hydronic boiler operating at or <140F, a hi temp hydronic boiler @ >180F or steam boiler?

Gas Condensing Boiler High Efficiency Heating



Ultra high efficiency boilers have become one of the best buys in home heating. These high efficiency boilers have changed dramatically from the first pulse boilers that I had the privilege of installing twenty years ago. Today’s condensing boilers are much more reliable and will not shake and rattle the windows of your house like those old beasts did.

If you are looking to purchase or install a new boiler for your new or existing heating system then you need to look a condensing boiler to heat your home with. In the past twenty years the condensing gas boiler has evolved to be a reliable, very efficient way to heat your home.

Radiant heating systems with the right design feature can easily heat your home at temperatures that use just warm water. At these temperatures the water is pulling the exhaust temperature of the boiler to very low points. This gives you extremely efficient boiler operation.
The boilers of today are made to operate continually at temperatures of 100F or less. At these temperatures it is not uncommon to have the combustion analyzer give me readings of 98-99 % efficiency. To get these types of readings and still heat your home the heating system has to be designed to work at these temperatures.

The right condensing gas boiler coupled with the right heat transfer system to get the heat into your home the right way will give you the most efficient heating system possible with today’s technologies.

Do a bit of research and find a heating contractor that knows exactly how to install a condensing boiler with a radiant heating system properly. For your radiant heating system to perform well at these temperatures, your boiler will need to be installed in exactly the right way. There is not a lot of room for error when designing very high efficiency heating systems. To wring every BTU of heat out of the fuel that is being burnt means that you are also on the ragged edge of supplying just enough heat to the building to over come the heat loss of the building at any given time.

My combination boiler vaillant turbo max is not building up presure what can I do ?


Check the warning pipe to see if water is coming out. If it is then the pressure relief valve is passing and will require cleaning\replacing. If the water in the system is dirty then the capillary tube to the pressure gauge may be blocked this normally means changing the gauge. If neither of those are satisfactory then you may have a leak on the heating system or heat exchanger.
If the pressure is going up but dropping off when the boiler cools down this indicates the expansion vessel diaphragm needs recharging or replacing

High pressure in central heating boiler going up to 3 bars


you need to provide more info on the system, it may be best to get a hydronic hearing expert to call out. this could go really bad if you fiddle with pressures

Radiators not getting up to temperature


depending on the piping configuration; Series loop or mono-flow, you might need bleed the system. If its a mono-flow you would have bleeders on the radiators. Bleed them only till you you have water coming from the bleeders. If its a series loop, you need to bleed them from the area of the circulator by the boiler. There is a urge system you need to use and see if you can get the information on how to do that. I would think that somene here as written a tip on how to purge a series loop hydronic system. Also check to see that you have somewhere in the 12-15 PSI on your system pressure.

Hydronic heat water feed valve


You should be ok. Most of the time the boiler are charged to about 10psi and dont have feed valve. You would only feed if you have a slight leak in system. Rus

IS A HYDRONIC ELECTRIC BASEBOARD MORE EFFICENT THEN THE STANDARD ELECTRIC BASEBOARD HEATER


I have some confusion about what you are asking......

There is no such thing as "Hydronic Electric Baseboards"......

I am assuming you are referring to the oil filled baseboard heaters. If so....

The same amount of btu's required to heat a space remain the same whether the elements heat a liquid to warm the air or whether they heat the air directly, the same amount of wattage will be consumed. So, their is no more or less efficiency between the two.

If you are referring to "Hydronic Baseboard Heaters" (these baseboards are fed from a boiler with a pump) Then....I will assume that it is a gas boiler. In which case, the gas boiler would be more cost efficient to operate. If it is an electric the same rule applies as above......the cost is the same.

How to re pressurisecentral heating system


Hi tiger650,

I'm Harvey the Master Plumber.

Your problem is: The Alpha SY24 boiler has stopped working. The pressure gauge has dropped, you need to know how to re pressurise the system once the radiators have been bled

Every hydronic heating system is required to have a presure regulator. Most guys call it a feeder valve. Every one I've installed or worked on had one. It's job is to keep the water pressure constant by adding water when you release some air without over filling the system. Sounds like it's not working. Some types can be serviced, others cannont so you may have to replace it. If you're not sure what to do it might be prudent to check the Repair Directory for a repairman.

I have a bosch 24cdi rsf combination boiler reaching 3 bar pressure and blowing off through release valve. any suggestions.


if this occurs when the unit is in use for only hot water, there will be an internal leak in the secobndary heat exchanger, you will have to replace it. check first that the charging link has been removed when testing to ensure it is not passing.
if it happens when the heating is switched on then check the presure in the expansion vessel ( dump all presure from system and use a car foot pump with a gauge there should be 1 bar presure) that is the big red thing behind the pump, if water comes out of the test valve on the front of it when you try to test it or it wont hold the presure you will have to replace it (a nasty job you have to strip half the boiler) if you can pump it up make sure you release the presure in the system as you pump it or you will get a false reading
