do you know if this model is still available? I don't have a power shower and mains cold through out no cold tank. I though if I changed to the sealed system then I could fit a shower from the mains hot and cold. But I know changing like for like would be easier.
I would ultimately like to replace the boiler with a combi one so I can get rid of the tank all together but can't really afrord it at the moment

Do you know where the best place to get a tank from would be?
