Perimeter Heating

HCP's Perimeter Heating range offers a choice of either Low Pressure Hot Water (LPHW) or electric heating elements. As the name implies, Perimeter Heating is usually located around the perimeter of a building and on the external walls, where the heat loss is greatest.

Perimeter Heating casings can be independently supported at low, medium or high levels to give continuous heating along walls or walkways and is ideally suited for combating cold down draughts and condensation, characteristics often associated with full and half height glazing.

Drawings

Detailed below is a traditional wall-mounted heating system, but HCP can design and manufacture systems to match space restrictions or output requirements.

1. Heating Elements are made from copper tube with aluminium fins. They take standard capilliary fittings
2. Wall Mounting Brackets
3. Heating Element Hangers
4. Front Panel
5. Centre Mullion is shown, left-hand, right hand and closed end options available
6. External Corner Cover Panel (internal also available)
7. Outlet Grilles are continuous aluminium extrusions. Standard finish of silver anodised AA5 (Punched slotted outlet also available).

Specifications

HCP’s elements are manufactured from copper tubing, which are available in diameters of 15, 22 or 28mm; enhancing the heating output is a profiled grille of extruded aluminium.

Our standard systems are available in five sizes, but by increasing or decreasing the diameter of the copper tubing and aluminium grille, the length of the element and/or the number of elements a wide range of heating outputs can be achieved.

For the purposes of illustration, we have shown three different Perimeter Heating systems (Sloping Top Grille, Top Grille & Front Grille) below. Their heights and widths can be altered –see performance details below.

Sloping Top Grille (STG)

Top Grille (TG)

Front Grille (FG)

Performance

The performance data below can be applied to the TG (Top Grille outlet), STG (Sloping Top Grille outlet) and FG (Front Grill outlet) units.

HCP offer four widths of casing: A, F, N and W; 40, 60, 90 and 120mm in width respectively. Performance based on the unit height and number of elements (SR & DR) is detailed below.

Design

Design and adaptability are fundamental to the HCP philosoply, so whatever your space restriction or output requirement, we can design a system to suit your needs. There are a wide range of standard polyester powder-coat colours available to meet demanding aesthetic requirements.

Options

HCP’s perimeter casing can be modified to suit your requirements, which can include split mullions for partition points. Acoustic baffles can be integrated within out units to counter the transfer of noise between rooms.

Cabling is often integrated within our units and you can choose between a high or low-level cable duct; Separate and multi-cable ducts are also available.
