We live in a circa 8 year old detached house in the UK.
We've been having some problems with our heating system, mainly the hot water tank and we're wondering how much work is involved to change to a combi boiler (we want to get rid of the hot water tank so we can use the cupboard as stairs to our attic anyway so this is the perfect excuse ;-)).
Looking online there are some conflicting accounts of the work involved.
Is it just changing our boiler in the kitchen to a combi boiler, removing the hot water tank upstairs and "joining up some pipes" or will we need work done in every room?
Trying to understand the amount of required "damage" that might happen!
