My two suggestions are not 'just plain crazy'. I was suggesting one 500 litre twin coil cylinder, each coil of which can transfer 70kW, and a single boiler of adequate capacity to heat the building. How you supply the incoming cold water for your drawoffs is a different matter; I was giving good advice on how to store and heat the domestic hot water and the house with weather compensated control. This is far better than paired boilers with just on-off control, and will take up less space and have fewer components to go wrong.
It is entirely your privilege to ignore or adopt my advice; there is no need to be so rude.
