We are about to embark on a loft conversion. We will be replacing the boiler at the same time and are not sure of the best option.
The property will have a bedroom and en-suite in the loft (shower/sink/toilet). There is a bathroom on the first floor (bath/sink/toilet-shower is integral with bath via mixer taps) serving 3 bedrooms and there is a toilet with sink under the stairs on ground floor. There is also a sink in the kitchen and one in the conservatory area).
We are thinks a megaflow is the way to go, which I think consists of a boiler and a tank. Is this correct and is this the best option?
an expensive option but if you can afford it then yes i would say its the best option, i'd mate the unvented cylinder to a vaillant or worcester boiler.
