I recently had a boiler serviced. I also had a pressure pump placed in my hotpress. Now my gas boiler is leaking all over my countertop, mainly when in use, quite a bit. Boiler is 20 years old. Guy who serviced boiler says I should consider putting a pressure vessel in my hotpress. Im not sure if this leak is linked to the installation of the pump. He says cost of putting in expansion vessel will be around 250. Cost of new boiler is 2k. He says heat exchanger in bolier is also badly scaled so that even if i put in this vessel the life of the boiler is limited. Any opinions on this scenario welcome ? What is the lifespan of a vokera boiler ? Is it worth doing this fix ?
