  1. Underfloor Heating Guidelines

    Below we have compiled some useful guidelines to help answer some common questions about the installation of water underfloor heating; Flow Rate To calculate the flow rate for each underfloor heating loop, take the loop length and divide by 40. For example, 100 m loop length/40 = 2.5 l/min flow for the underfloor heating loop. […]

  2. Underfloor Heating Automatic Bypass Valve

    Normally the underfloor heating flow rates per underfloor heating water loop is between 1 – 4 l/min.  The flow rate for the water underfloor heating system can be regulated on the underfloor heating return manifold.  Each loop can be adjusted to suitable settings.  ie longer loops would normally be fully open and the shorter loops […]

  3. Flooring Tips For Underfloor Heating

    Most floor finishes will work well with underfloor heating.  Always check what the maximum surface temperature the floor finish will operate at with the manufacturer of the floor finish. If using wooden boards for underfloor heating, it is best to use engineered boards, one layer 21 mm.  Avoid using wood on top of wood.  Maximum 25 […]

  4. HENCO Underfloor Heating Pipes

    HENCO underfloor heating pipes are normally bent without any special tools.  When the pipes have been in service and temperature and pressure decrease, the pipe contracts.  With an approved fitting range the grip between the pipe and fittings is stronger than the contraction force and does not give any problem provided the installation of the […]

  5. Underfloor Heating Lockshield Valve

    An underfloor heating installation with different pipe loop lenghts and water flow requirements will have different pressure drops for the different loops.  In order to achieve an even heat distribution between the rooms in the installation the pressure drop of the different loops must be balanced. In the Underfloor Heating Systems Ltd system this can […]

  6. Underfloor Heating Water Flow

    The water in the underfloor heating system must flow in order to convey heat to the floor.  The size of the water flow is determined by the amount of heat to be conveyed and the designed water temperature drop. Depending on the interior of a house, the rooms are of different size.  This means that […]

  7. Underfloor Heating Loop Patterns

    For underfloor heating water there are three main types of underfloor heating loop configurations.  The type of configuration depends on the construction techniques and practices in different countries. In general when pipe layout plans are being formulated, attention should be paid to routing the supply flow to the external walls or other potentially cold areas, […]

  8. Underfloor Heating Reinforcement Mesh Installation Information

    The steel reinforcement mesh of the floor structure offers an easy and economic way of fixing the warm water underfloor heating pipes according to the required layout pattern.  Maximum distance between fixing points to the mesh is normally 750 mm and at bends 300 mm. Water underfloor heating pipe loops are laid on a mesh, fixed with […]

  9. Underfloor Heating Pressure Drop

    The temperature of the water in the underfloor heating pipes is determined by the room temperature that must be achieved at a certain q-value.  This temperature is the mean water temperature. Underfloor heating systems are normally designed for a temperature drop across the pipe loop of 10 to 15 degree C.  A low temperature drop […]

  10. Underfloor Heating Response Time

    Different factors, all interrelated, affect the response time of an underfloor heating installation: 1. Climate conditions Climatic conditions vary in different parts of the world.  Water underfloor heating systems are designed to cope with the temperatures of the coldest months of the year.  This implies that the underfloor heating system is designed to work properly […]
