With the likely culprit being the aforementioned leakage, under or over pressurisation could result in no hot water from your combi boiler. If your boiler is low on pressure , it can usually be solved simply through a DIY top up.

If your system is leaking from the boiler pressure valve then it’s best to check if the pressure is too high. The boiler pressure relief valve is designed to leak water as a safety protection feature to prevent damaging your appliances.. To identify if you have an over-pressure fault, look at the gauge needle on your boiler, it should be pointing in the green section, set to around one bar.

Hot water heating system leak diagnosis & repair: Here we explain how to determine that a hot water heating system is in fact leaking, and second we describe how to find the location of hidden leaks in or on heating boilers, hot water heat piping, baseboards, …

  • There is a leak from the bi-thermal heat exchanger between the heating and hot water bodies. Leaks from your system are most common, but components within the boiler leaking – usually due to age and corrosion – are not far behind as a leading cause. How to identify a leak in your boiler If you’re comfortable, you could remove the cover from your boiler and carefully look for signs of water.

5. If there are no leaks near the boiler, check the radiators in each room. Look for signs of water around the hand valve, at the connection of the steam pipe to the radiator, and at the air vent on each radiator. 6. If there are no obvious places where water is leaking, shut off the boiler and allow it to cool.

  How to Find a Leak in Your Central Heating Syst

  • No Heat or Hot Water. Potential causes include broken diaphragms and airlocks, failure of … Check the thermo valve pipe – look for a cold spot along the pipe’s thermo valve, which is located along the boiler’s radiator. If the radiator is cool, but the pipe is hot, the blockage is in one of the radiator valves. If the entire pipe is cold, look for the coldest spot to indicate where the blockage is.

Hot water boiler systems also have a high-limit temperature setting that triggers an automatic shutdown if the water temperature rises above that set point. If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking.
