I have a 10 year old Worcester Bosch Greenstar boiler in a property I just bought.
The boiler has a strange issue. The pressure drops down to zero leading to no hot water and then if you re-pressure using the key at the bottom, the boiler works for a couple of hours before the pressure goes down to zero again.
I called out a gas engineer and on his first visit, he found that the pipe leading outside was leaking. He did something to fix it but this did not fix anything. He came back for a second visit and poured in three bottles of Fernox leak sealer. He advised me to run the heating for a couple of hours. This did not fix the issue either! In fact, the pressure now drops faster than before.
The boiler also has this chugging noise all the time - not sure if this is the norm with this model.
I called Worcester and they said that the heat exchanger has a warranty of 10 years.
If an engineer turns up to fix it, it will cost me £128 and this part will be free.
If the engineer finds any other issues, it will cost me £300 in total.
I can also take a subscription where I pay £50 for 6 months and during this time, they will fix any issues with the boiler. If they cannot, they will give me £750 towards a new boiler.
What do I do ?
