Is it worth replacing the heat exchanger?
Unfortunately, the cost of replacing a heat exchanger isn’t the most affordable choice. The cost of replacing a heat exchanger ranges from $2,000 to $3,500. However, it is not worth spending your money on replacing your heat exchanger when it is near the end of its life span, which is ten years or more.
Can a boiler heat exchanger be replaced?
Boiler heat exchangers usually crack when they develop faults. Repair isn’t an option, so you’ll need a replacement. Expect to pay anywhere from £350-600 for a new heat exchanger for your boiler.
What does the heat exchanger in a boiler do?
The purpose of a heat exchanger is to transfer heat from one fluid to another, hence the name. In the case of a boiler, this means transferring heat from gas to the water that will be circulating around your home to the radiators and hot water tank.
How do you reset a Vokera?
To reset your Vokera boiler, move the mode selector switch to the ‘OFF/RESET’ position and then move it back to either ‘hot water only’ or ‘heating and hot water’. Should this reboot get your boiler working again then you’ll know because there will be a constant green light.
What to do if expansion vessel in vokera boiler is faulty?
If its low it will give you the same symtoms as a faulty PRV as when the water heats there will be no room for expansion and the pressure will rise until it opens the PRV. Anyway if the pressure is low you can top it up with compressed air from a pump and test again in about a week to see if the pressure remains
How old is the boiler on a vokera?
The boiler is only 5 or 6 years old. I also read in forums that getting to the vessel means possibly upsetting other parts and having to replace the boiler completely. Anyone has any experience of how likely to happen this will be on a Vokera? I’m trying to understand:
Why is my boiler plate heat exchanger not working?
If the boiler has a modulating gas valve the flame will reduce accordingly and you will get plenty of very cool tap water but usually with a steady temperature. The more common way for the plate heat exchanger to block up is for the heating waterway to be clogged up with black oxide sludge and debris.
Can a Gas Safe registered engineer repair a vokera boiler?
These are some of the more common faults that will prevent a Vokera boiler to ignite but there are many more possibilities. A Gas Safe registered engineer will be able to safely diagnose and repair the fault that’s getting in the way of your Vokera boiler igniting.

What can cause a faulty boiler heat exchanger?
The trigger can sometimes be because the water is overheating, but it is far more likely to be a water circulation problem. In other words, the sludge and debris is restricting the water flow through the heat exchanger and around your system.

What should I do if my heat exchanger is beyond repair?
If your heat exchanger is beyond repair, you will be left with the stark choice of replacing the component, at a cost of at least £500 or buying a new boiler. While a new boiler will cost more, the difference is actually not as much as you might think and in the long run a new boiler is likely to save you money.
