The Elecro Vulcan heaters are supplied with hose tail adapters for connection to flexible pipework. Construction consists of a flow tube which is fitted with Inlet and Outlet mouldings manufactured from specially formulated polymer alloy material. Universal ABS unions are provided to allow solvent weld connection to the inlet and outlet pipe work. The outlet moulding accommodates a reversible flow switch with a gold tipped reed, and Titanium fulcrum pin. The heater is supported on two swivel feet; these can swivel to permit either wall or floor mounting.  NB You will need to supply a hose for connection between your pump and the heater.  Many customers simply cut a short length of hose from their existing hosing to use as a connector between the pump and heater.

The Elecro Vulcan swimming pool heaters come fully equipped and pre-wired including a super sensitive flow switch, that allows safe coupling to most above ground pools. Please check the technical page of the manufacturers for information on connectivity to your pool before purchase. Please use the link - http://www.elecro.co.uk/support-swimming-pool-heaters - The connections supplied with your Elecro heater are a stepped 1¼" BSP & 1½" BSP (British Standard Pipe). If your Intex pool uses 1.5" hoses with threaded nuts you may wish to buy 2 x Adapter B's (part 10722) and a piece of 1.5" hose (part 11010) which are available from John Adams in the UK to make a sealed connection. It is also possible to make the connection to the 1½" (38-mm) part of the hosetail using 2 jubilee clips & silicone sealant at each side of the heater.

The heater requires only final connection to a mandatory separate RCD. No pump interlock is required. All heaters come fitted with 1.5'' BSP female threaded adapters for connection to all pipework.

The desired pool temperature can be easily set on the Vulcan heater using the panel-mounted thermostat dial in the case of the analogue model, in respect of the digital model by using the touch buttons, resulting in the temperatures being displayed on the LCD screen. Over-temperature protection is provided by the thermal cut out (manual reset).
