Underfloor Heating: Effective and Economical

In recent years underfloor heating has been widely acknowledged as one of the most effective methods of heating. It has become the fastest growing market for both domestic and commercial heating sectors.

How It Works

Underfloor heating works by heating your home from the floor upwards. This form of radiant heating is different to the heat provided by radiators, which works by convecting warm air around the room. The main advantage of  underfloor heating is its high level of performance. Radiant heat means that the warmth is concentrated where you need it most. You’ll enjoy uniform heat, with no cold spots or draughts, and it’s perfect for human comfort – you won’t get cold feet and you will keep a cool head.

Hydronic Pipes and Fittings including Underfloor

AluPex Multilayer Pipe

Hurlcon Hydronic Heating’s AluPex multilayer pipe is manufactured from a core of high density polyethylene, a mid-layer of aluminium foil, and an outer coating of high density polyethylene. These layers are bonded together with two adhesive layers. The combination of polyethylene layers gives an extremely strong and resilient pipe with excellent flexibility when required. The aluminium layer allows the pipe to hold its shape when formed into a radius, greatly reduces thermal linear expansion, and provides an oxygen diffusion barrier, making it extremely suitable for radiator panel system installations. These same characteristics also make Alupex excellent for use in conjunction with studded polystyrene insulation panels, for in-screed hydronic underfloor heating systems.

With a range of quality fittings available from NTM for use with AluPex multilayer pipe (pictured right), all installation requirements can be covered.  Ensure a quick installation with ease, peace of mind and longevity.

NTM Multilayer Pipe Fittings

N.T.M. S.P.A. is a leading Italian manufacturer of fittings and markets its products in Italy and in more than 50 foreign countries. Relocated to Brandico (also in the province of Brescia) at the end of 2004, it now operates a 10,000 square meter facility.  N.T.M. S.P.A. is a constantly growing company with a production capacity of 200,000 fittings a day.  The name N.T.M. S.P.A. derives from the name of its founder, Mario Tripoli, who, along with the management team at N.T.M. S.P.A., has 30 years of experience in the design and manufacture of brass fittings.  N.T.M. S.P.A. profits from his extensive know-how, carrying on the best tradition in the industry and guaranteeing its customers maximum quality and next-generation product ideas coupled with state-of-the-art technologies.

Oventrop Copex Pipe

Oventrop Copex pipe is used for in-slab hydronic underfloor heating systems. Manufactured from high density polyethylene Oventrop Copex is cross-linked under high temperatures to give a highly resilient yet extremely flexible pipe. It is highly resistant to chemicals and has a working temperature range of -20 deg to 90 deg C at pressures well above typical operating pressure. The smooth bore of Oventrop Copex pipes prevent sedimentation and flow loss over time. Copex has an EVOH oxygen barrier protected under the highly resilient outer PEX-Xc layer.

The light weight, strength and flexibility of Oventrop Copex pipe makes installation of hydronic underfloor heating systems fast and easy.

SBK Modular Manifold Systems

The German designed and manufactured SBK modular manifold system is comprised of individual ‘blocks’ which can easily be assembled to the required number of heating circuits  and allows for fast on-site alteration to circuit numbers as well.  Blocks are coloured coded for flow (Red) and return (Blue) piping, and are available as plain blocks or with flow control valves and flow meters. Flow control valves can be quickly removed to allow for thermal actuators in zone controlled systems, and the SBK patented flow meter allows for easy and accurate flow adjustment. Constructed from glass reinforced plastic with a multi-chamber design, the manifold blocks are corrosion resistant and have inbuilt insulating properties. This means greatly reduced heat losses for heating systems and less risk of condensation in cooling systems. The individual blocks are reversible allowing pipe circuits to be directed upwards if required, and the internal geometry results in a minimum pressure drop through the manifold system.

SBK offer a 5 year warranty against manufacturing defects.

Studded Insulation Panel

Hurlcon Hydronic Heating’s Australian made studded polystyrene insulation panels are perfect for installing a hydronic screed heating system over your structural slab or existing floor. The 1200mm x 800mm panels interlock around each edge to make installing simple and fast while still providing a strong and seamless base to work on. The AluPex or Copex pipe is inserted between the studs and held firmly in place, with staples only required to secure the tight bends. The expanded polystyrene is high-density, flame retardant and 100% recyclable, and can be cut with a handsaw or knife, and the 30mm base thickness gives excellent insulation against downward heat losses. The studs are capable of securing pipes up to 20mm diameter.
