Hi another top tip whether you are looking to buy a B&B, a house to convert to the above or to expanding your own operation. Take a good look at your boiler! will it take the extra load? We are going to put in another 3 rooms and build a flat so we are going to have to put in a second boiler to run this extra capacity. The one we have is right up to the limit so as we want to put in another couple of radiators and put in some larger ones we are going to have to change that as well therefore my advice is check that what you have will provide enough hot water. We have a lot of electric showers which produce their own hot water which is very useful when we have 11 showers on the go at once. Also it is important to think about when you do things for example we don't use the dishwasher or washing machines at the same time as peak showering time so be prepared to amend your schedule.
