Hi.
I am upgrading central heating (at same time as kitchen / removing AGA etc) and I have a relatively large house, almost 30 years old, 5/6 bedrooms, 2 adults and 3 kids live there.
My question is should I go for a combi boiler (Worcester Greenstar Highflow 440) or a system boiler? We have 3 showers, 4 toilets, only one bath in the house, I would say it is very rare that someone will be taking a bath at the same time as a shower. However it is very likely that someone will be taking a shower at the same time as someone else flushes the toilet / washing machine or dishwasher on / runs the hot water for dishes etc.
I realise that the combi is easier to install, less hardware (no cylinder), I guess that cost wise the system boiler will be more expensive due to increased labour. However I am keen to get it right, I have heard that combi systems can provide interrupted flow (shower going cold when another toilet is flushed etc) and would be very interested to hear advice from professionals (other than my plumber) and related experiences. I have plenty of unused loft space (currently 2 cylinders in there!).
All help greatly appreciated.
