First post, so please bear with me.
We need a new boiler in our house and have had a lovely plumber calculate our Heat Calcs (heat loss?) for the house to be 34.87 kw. We have 3 bathrooms, but only use 2 of them unless we have guests (rarely!!) - my question is how do we calculate the hot water need in order to calculate the size of the boiler? We have a Tribune HE 210 litres unvented cylinder which has always been plenty big enough for our needs.
Or have I got the wrong end of the stick and you can't add the two together to get a rough idea of the KW you need from the boiler? We currently have a vented 'regular' boiler with an unvented HW cylinder - and are looking to move to a sealed system throughout (not sure whether that makes a difference to the calculation).
Many thanks - and apologies to the professionals out there who are tired of answering obvious numpty questions from desperate housewives!!
