Hot Water Heating Coils

Replacement Coils

HC Coils can supply a cost effective replacement coil solution when your heating or cooling coils are beyond repair. Frost damage, corrosion, or simply just wear and tear can cause critical coil failure which can in turn cause a complete system failure.

Visual checks will normally determine whether a coil has failed, with tell tale signs being leakage of fluids and / or inconsistent temperature control. If you think you have a failed coil that you need replaced contact us and we will supply an estimate and manufacturing lead time to replace the coil.

Our preference, and the most accurate method for replacing the coil, is for you to send in your damaged coil so we can measure it precisely and give you an exact replacement. If that is not practical, we can supply you with a step-by-step document that will guide you through the process of taking the measurements yourself.

We will aim to match the tube configuration and connecting pipework where possible although there are instances where this may not be physically possible, however in such instances we can match the overall casework dimensions to ensure that the coil will fit back into the air handling unit or duct work on site.

Typical turnaround for replacement coils is 2-3 weeks from drawing approval. All replacement coils will be manufactured at our Gosport factory and sent back out to you for installation.

HC Coils Hot Water Coils


Coils are constructed from Seamless Drawn Copper Tube to BS2871 mechanically expanded into aluminium fins with die formed self spacing collars. Copper return bends and tubular copper headers are silver brazed into the tube ends. Flow and return connections are BSP(M). Air vents and drain sockets are provided. The coil casing is formed from heavy gauge galvanised sheet steel to BS 2989 to make a rigid assembly. Tube end plates have die formed collared holes to allow expansion and contraction of the tubes without damage.

Optional features.

Polyester Coated Aluminium Fins are available to give protection in certain aggressive environments. Alternatively, Plain copper or tinned copper fins are available.

For Positive Pressure or High Pressure Ducted Systems Boxed Ends should be specified to enclose headers and return bends and minimise air leakage.

Brass or Stainless Steel Casings are also available.
