External boiler and piework query.

    Hi all,

    My latest rant about my errant builder involves the positioning and pipework associated with my external oil boiler.

    He has placed the boiler at a slight slant against the house (i.e. top is leaning against the house and bottom is about a centimetre out). The pipework (qualplex) has been sheathed in the grey tubular insulation used on internal pipes to insulate them from frost damage and have been placed at ground level whereby they run from the boiler about 12 feet to the external bathroom wall where he has punched a hole through the wall and run them into the bathroom and across the floor (in a groove he dug out) and then through another wall into the hotpress.

    Now my queries are as follows:
    1. Shouldn't the boiler be in an upright vertical position away from the wall to allow air to circulate and reduce any risk of dampness coming into the house from rainwater seeping down between the boiler and the wall.

    2. Is qualplex resistant to frost damage and shouldn't it be buried underground to prevent damage from weather, mice etc.

    3. Won't there be dampness (and "cold bridging") issues with the hole punched through the wall (and damp proof course) even when he fills it in with concrete.

    The old boiler had copper pipes running directly into the house and so I didn't have this problem with pipes running along my patio keeping the garden warm.

    Don't know much Dave about plumbing but I know that our plumber had to run pipe from boiler house five metres into house and he used a highly insulated (v expensive if I remember correctly) pipe buried in the ground in a trench. This was to prevent heat loss and resist frost.

    I thought qualplex couldn't be connected directly to boiler, I thought you needed at least 1 if not 3 metres of copper.

    Installation is not my side of things, but that grey foam insulation will rot away in a few months. You need something like Builderwoman suggests, or at least the pipes and grey foam should be run in a lenght of pvc pipe that can be sealed, or above ground, at both ends.
    Towbar, I think that you are correct, although I think that I heard somewhere that there is somekind of plastic piping that can now be used right from the boiler.
