The electric version of the 3 inch Unibody Horizontal Model Steam Engine Boiler Kit is suitable for driving our single cylinder engines under light load.

Video of the boiler driving our Mill Single YouTube Video and (gas version) driving our Beam engine YouTube video.

The boiler has a simple cylinder design made of 3.5mm thick aluminium alloy, heated internally by an AC mains heating element - default 220/230v AC Heating Element (UK/Europe) , optional 110/120v AC (North America).

The boiler cylinder is provided complete and tested (certificate provided), the base is a kit of fully machined, unpainted parts that can be easily assembled with simple tools.

Electric steam boilers have a number of advantages over conventional gas or sold fuel fired boilers:
1. They are safer to use having no flame and can be operated indoors without the risk of carbon monoxide poisoning
2. Like an electric kettle, they are quick and easy to get up and running
3. They are cheaper to run - mains electricity is considerably less expensive than gas from cannisters and none of the heat goes up the chimney

The boiler comes without the heating element in place. The heating element is however simple to fit and wire up by a competent person - suitable mains lead and plug to be provided by the customer.

Steam output can be regulated using a variable mains AC voltage controller. A 220/230v version suitable for UK/Europe is available as an option. Similar 110/120v versions are widely available for North American customers.

It is recommended that the base is coated with heat proof black aerosol paint. The boiler can be left or sprayed black to match (as per photos).

The standard kit includes:
- Aluminium boiler body/cylinder
- Safety valve
- Steel base sides and ends
- 8 stainless steel screws
- Steam outlet valve
- Brass water fill plug
- 220/230v AC Heating Element (UK/Europe) or optional 110/120v AC (North America)
- Test Certificate and Instructions

NOTE: The photos are of the assembled and painted boiler with optional water level gauge and pressure gauge (0-30psi) and 220v AC Voltage regulator and also customer supplied mains lead/plug - see picture of parts as supplied.

Optional extras include ready made copper steam pipe (with connector for specific engine), water level gauge, pressure gauge (0-30psi) and 220/230v AC Voltage regulator. The water level gauge and pressure gauge are installed on the boiler cylinder if those options are purchased.

Warning: It is the customer's responsibility to provide the mains lead, ensure all electrical connections are made securely, the boiler is earthed and a working RCD circuit-breaker is always used to power the boiler - instructions provided. Always ensure the water level does not drop below one third boiler capacity hence ensuring there is sufficient water covering the heating element.
