Boiler for 3 Bathrooms & 16 Radiators

[Manj]

I need to buy a suitable boiler but unfortunately I do not know that much.

I live in a double fronted house with 5 bedrooms and 3 bathrooms.
I want the boiler to be able to maintain its pressure and heat even when 3 people are having a shower at the sametime.

I am quite intrested in the one below: -
Vaillant ECOmax 835/E

Any suggestions?

to size the boiler you need to work out the heat requirements for your house. i got the equations from a book on GNVQ plumbing from the library.
i fitted a vailant 822 system boiler. good instructions very efficient. if you are replacing the whole heating and hot water system some plumbers merchants will work out the rad sizes etc... if you give them the house plans.
with regard to the showers i think you either need a mains pressure hot water tank, a whole house pump or manybe even separate pumps for each shower. oh yes and a big cylinder!!!

Thanks Alex.

I have a good think about the 822 system boiler.
