Replacing 2 boilers with 1 larger one. Pros and cons please.

With 2 showers and a main bathroom, unvented sounds like the way to go. But you need to see if your mains supply is suitable first, and it is a costlier option.

For such a large property with multiple demands for water I really would not consider a combi boiler.

But that's my view. I like the smaller quieter boiler with instant hot water at very high flow rates. I also like that I have hot water using an immersion element when the boiler isn't working so need ever to call an emergency engineer. It'll mean losing the airing cupboard to put the bigger cylinder in so the water doesn't run out as you've described. 100 litres is too small.

I have no airing cupboard! The current 100 litres tank is a tall thin one that takes up all the space it is in.

The mains supply is 22mm coming in then splits to 15mm to serve 2 boilers and hob. Water is reasonable pressure but there is no way we could have a bigger inlet pipe fitted.
