Paid a visit to the homebuilding and renovating show at Bath and West
show ground yesterday (sat - also on today 30/11/03).

Bloke on the Eco-hometec stand said if you can't afford one of ours then
given choice of Valliant thermocompact or Keston Celsius get the Keston.

In the Keston documentation there is a sentence (underlined) that says
consider the possibility of the noise if installing near to a living
area. Can anyone with a Keston comment on this ?.

Flue options - the best place (for boiler) is under the stairs (only 6
feet from the 3/4 inch iron gas pipe supplying the kitchen) and the flue
can follow the underside of the stairs then go horizontally towards rear
of kitchen and follow the 110 waste water stack up the loft, then either
up to the ridge or out and down through the soffits.

Why can't I connect it to the waste stack ?. - i.e. well above the 'high
tide mark' ?

In theory this sounds fine. But, the stack is open so air is drawn in to
prevent suction as large volumes of water go down the waste (like a bath
emptying along with the washing machine and dishwasher). Dragging toxic
fumes into a sewer is rather naughty.
