Running pipework in Roof Space

[rogermelly]

I require a full new central heating system (including boiler) fitted at my house.

In order to save some money I intend to pipe in and fit the rads myself and then hand over to the boiler fitter to connect in and fit the boiler.

The house is a bungalow, so to save time I was going to run the pipework (I intend to use plastic barrier pipe) in the loft space and drop down to the rads.

Are there any draw backs to this method as opposed to running under the floorboards?? I was thinking there maybe pressure issues with the increased drops and rises to the loft.

Any advice would be greatfully received

In the roof, Frost protection required, Air relief valves to be fitted, unsitely drops in every room, Plastic on surface not pretty, Longer circulation runs, more pipe required.

Thanks for the response Reg man.

The walls are going to be boarded so that should solve the issues with appearance and the need for air relief valves is noted, cheers.

I was unaware that I needed additional frost protection on plastic pipe. Would that involve just lagging the pipework as you would copper?

Hi You could also use a frost stat (overrides controls when low temp is detected and fire up boiler/pump))
