Radiator piping in timber frame

    Using conventional rads in a timber frame house and panning to have finished floor before erecting frame which means all radiator piping needs to be done before the frame is erected.

    Has anybody done this, any tips or tricks? How do you get the placement of the pipes accurate? How do you keep them in place?

    Planning to run the pipes back to storage presses at each end of the hall and use a manifold so no joints under the concrete.

    Towbar, not necessarily. If you use a dropped system where the pipework is run in the joists and drops down the stud walls to the rads. The pipes to the rads come out through the stud wall.
    How do you get the placement of the pipes accurate?

    Virtually impossible to do, if you do want to put pipework into the slab and keep them straight going into the rad. If you want to keep the pipework in the floor put the two pipes together in the centre of the rad position and then you can branch off to either end on a second fix.

    Keeping pipework in the slab and hoping that it wont get bent or damaged is very difficult. Most TF houses that have a conventional heating system use a drop method, in my experience anyway.

    Should have mentioned its a bungalow so running through attic is not a problem.


    So the pipes from bolier would have to run up to attic and back down to rads?

    Is that doable, I thought it would result in airlocks?

    Still doable. You can fit automatic air bleeders at the highest point of the pipework. Still easier than trying to put pipework in the slab/floor.
    In a two story house the upstairs rads bleed the system of air.

    would definately agree with coming down through the stud walls - not a problem.

    If you really really wanted to do the services in the pre-fin floor then:

    1. fit the pipes in the base before the screed goes in, surround them in 2 layers of lagging,
    2. only leave 6-9" over the Fin Floor Level (FFL) and
    3. drop a 2" wast pipe 300mm long over it as a marker / protecter....

    but be warned, when the TF is going in,. warn the erectors not to damage pipes in floor or those protruding upwards.......

    i really have to advise that the services are integrated with the erected tf structure, far safer and easier to work with afterwards...!!!
