Hurricane SCH25 Hydronic Boiler & Narrowboat Kit

A 7.3kw diesel powered boiler with programmable timer and associated kit for fitment to a Narrowboat or Dutch barge. This hot water boiler has three major reasons for representing one of the best marine heating options on offer today......Efficiency, Reliability and Flexibility. Whilst the kit detailed below is primarily aimed at inland craft, with minor modifications or additions it is perfectly suitable for a wide variety of boats and applications.

If you would like to talk further about any of the information detailed below, or any issues relating to boat central heating, please feel free to email or give us a call on 01353 663095 or 01353 640008. 

  • The Hurricane is a true on-demand boiler that will give you a flexible and reliable heating system suitable for both leisure craft and liveaboards, combined with the programmable room thermostat the heater allows you to heat the boat as you choose, rather than dictating how and when you keep warm.
  • The fuel efficient burner is capable of burning a variety of diesel based fuels, therefore it is very tolerant of red diesel and the challenges it can sometimes pose to the smooth running of marine heating systems (the Hurricane will run efficiently on Diesel no.1, Diesel no.2, Arctic diesel, Kerosene and Furnace oil)
  • The diesel burner is efficient and reliable and quiet (therefore it wont sound like a jet engine firing up when running)
  • Both the fuel consumption and 12v electrical consumption of the Hurricane boiler are very low when considering its over 7kw output, therefore it represents a cost effective method of heating larger pleasure and liveaboard boats.
  • The design of the Hurricane boiler is based upon simplicity and reliability, most units are installed and maintained by the end user, therefore you shouldnt be paying out for expensive service engineers when buying the unit, or during its years of faithful service. The Hurricane comes with a comprehensive installation manual, however we realise that the correct specification and fitment of a heating system can be daunting; as retailers who specialise in heating systems Ely Boat Chandlers are very happy to offer our customers technical support and advice right through from the first enquiry to the final fitment.

So what can it actually do?

Below we have put together some fairly detailed explanation of what is included in the kit, how the system fits together and what is involved in fitting one. However it is important at this stage to clarify what the Hurricane is capable of.....

  • The boiler is very tolerant of poor quality diesel and the starting and stopping often desired in a domestic heating system, therefore this allows it to be controlled in a very similar manner to your home heating system - This reliability is a crucial advantage in allowing the heater to be used far more flexibly than many of its competitors.
  • The Hurricane can control upto four different heat zones, the Narrowboat kit supplied has two heat zones (the main living area and the hot water tank). Both these heat zones can be controlled with the timer, therefore you can set your hot water requirements and heating requirements independently to suit your preferences. This is one of the few heaters on the market to be able to control hot water and heating independently in a reliable manner (that doesn't significantly compromise service intervals and reliability).
  •  Below we have detailed the fitment and control systems, however a simple explanation is the following: The Hurricane is usually mounted in the engine room (and has no controls or switches on it), this is connected to a separate stainless steel box called a control board (this has an LED display that shows the status of the heater and has a switch to turn the Hurricane on or off). The control box is normally mounted in a discrete place out of the way because also supplied in the kit is a remote LCD display (this displays the status of the heater in plain English and has a switch to turn the heater on or off), this is smaller and far more suitable for mounting in the living area. Also connected to the control board are a programmable thermostat timer and a cylinder thermostat. These two working together allow you to set the Hurricane heating system to turn on and off at desired times and temperatures.

  • The Hurricane boiler unit is 22.8cm High x 33cm Wide x 48.2cm Long
  • Heat output 7.3kw (25,000 BTU/h)
  • Diesel fuel consumption 0.84 l/hr
  • Muffled exhaust for quiet operation
  • Electrical input 66 watts (11v-15v DC) (ignition draws an additional 2A for 30 secs)
  • Sealed combustion (balanced flue) to meet BSS regulations (when fitted correctly)
  • 3yr / 3000hr warranty on water jacket
  • 2yr / 2000hr warranty on running components (exluding service items)
  • Full programmable timer and thermostat

Where to mount the boiler?

  • The connections to the heater are on the top, however for installation and servicing you will also need access to the front panel. Therefore when mounting you will need to leave room to access the front, for connections to fit onto the top (air inlet, exhaust, water inlet, water outlet, fuel connections, a top clearance of 25.4cm needed), and you will need to leave space on the LHS of the boiler as this has another panel that will need to be accessed for installation and servicing. When looking at the main picture of the heater this can be visualised as the following: the front being the end with the viewing window and hour counter, access is needed here to service the burner, the LHS is on the left of the picture, you can see various inputs and outputs lined up on the top of the heater. Access is needed to this LH side because the panel is removable and the majority of the heaters pumps and control systems are located inside, hence this side needs to be accessible for maintenance.
  • The heater must be mounted horizontally on a flat surface and fixed down (using the 4 securing bolts provided)
  • The maximum length of straight exhaust pipe permissable is 12ft / 3.7m, including one 90 degree bend. Each additional bend will reduce the maximum permissable length by 1.5ft / 46cm (because a bend slows the exhaust gasses and increases back-pressure).
  • The Air intake hose should be kept as short as practically possible, and should not exceed the legth of hose provided in the kit.
  • The exhuast outlet and air intake should be mounted atleast 30in/76cm above the waterline, and the inlet and exhaust hoses should be "goose necked" to prevent water ingress. These dimensions can sometimes be difficult to achieve on a Narrowboat, therefore there are compromises that can be made when taking into account the placid nature of inland cruising. Please feel free to call us to discuss this issue should you require clarification (01353 663095).

 The Fuel system

  • The fuel connections are a fuel-inlet and fuel-return, both are 1/8" BSPT fittings that connect to the fuel pump inside the unit.
  • A minimum diameter of 1/4" / 6mm fuel line should be used. For installation on inland craft this must be copper or ISO7840 rubber hose.
  • The heater should be no more than 60" / 1.5m above the fuel tank (level from which the fuel is drawn).
  • A shut off valve and appropriate fuel filter should be fitted in the supply line (neither are provided in the kit).
  • As with any heating system a dedicated fuel supply from the tank is very strongly reccomended. This can either be a side or top take-off. What you are trying to avoid is the following: 1) The fuel pump battling against the engine fuel pump, 2) The heater being able to drain the tank completely so that the engine wont run, 3) The heater being starved of fuel or overfed with fuel from a pressure head.

The Electrical system

  • The main control board is housed in a stainless steel box with LED display (for status and diagnostics). This is connected to the heater via a 15ft / 4.6m long harness (interface cable).
  • There is an electrical terminal on the main control board for the primary 12v DC feed, there are no direct 12v DC power feeds to the heater itself.
  • The 12v DC power feed should ideally come direct from the domestic battery bank, the wire gauge should be sufficient to permit no more than a 3% volt drop, and a 25A inline fuse should be fitted (not supplied in the kit).
  • The control board (in the separate stainless steel box) is where you connect the thermostats (upto four) and any fan matrices you may wish to install.
  • The remote LCD panel supplied in the kit is connected to the Control board (in the separate stainless steel box) by a 25ft / 7.6m RJ11 cable. This allows control and diagnostics of the heater from inside the boat.

The Plumbing system

  • The Hurricane boiler has an output of just over 7kw, therefore we reccomend you install 7kw of radiators or matrices in the system, this will allow the boiler to fulfill its full potential in times of extreme temperatures.
  • We strongly reccomend that you configure youre heating in a standard flow-and-return configuration (please see the example plumbing diagram on this page)
  • A good tip is to put shut-off valves either side of the heater so that it can be isolated for installation, maintenance or repair purposes.
  • The Hurricane boiler Narrowboat kit comes with an electrically operated solenoid valve and cylinder thermostat. This allows you to isolate the calorifier and run a "summer circuit" (where the boiler heats the hot water cyclinder only rather than the entire heating system). This solenoid is in the process of being updated to a motorised valve, in the near future, this is a small technical improvement, but doesn't change the operating principles of the original system.
  • The circulation pump supplied with the kit is positioned seperatley to the heater itself. Ideally it should be positioned so as to push cold water into the heater, NOT pull hot water out of it and the push it round the system.
  • The narrowboat kit is supplied with an air separator and header tank. The former is plumbed into the flow and return system at the highest point and the header tank then connected. This will allow for some bleeding of air from the system and expansion of the water contained in the circuit.
  • The water connections are made to the heater using the silicone elbows supplied in the kit. The elbows are jubilee clipped onto the inlet and outlet (ontop of the heater), the bleed valves supplied are then fitted onto the elbows, then the straight silicon sections supplied are fitted onto the other side of the bleed valves, you then connect your plumbing system to these silicon straights. This arrangement provides a heat rated input and output for the heater, gives robust and compact 90 degree bends to minimise the height taken, and facilitates bleeding of the system input and output.

 The Control system

  • The room thermostat is programmable and is what enables you to control the Hurricane boiler much as you would your home heating system.
  • The heater is connected to a main control board by a 15ft / 4.6m harness. This box has an LED display that shows status and fault diagnostics. However "everyday" access isn't needed to this panel so you would normally mount it out of the way.
  • The remote LCD panel provided is mounted in the living space of the boat. It is connected to the control board via a data cable. This small panel has two functions, it allows you to switch the Hurricane system on or off, and it provides a written display of the boilers status (including faults) to compliment the LED display on the control board.
  • The room thermostat is programmable for the heating system and hot water. this should be positioned in the living area of the boat, this will then in turn giving an appropriate reading on the thermostat that controls the boiler, and provide easy access.
  • The cylinder thermostat is fitted to the calorifier. It needs to be fitted below the insulation and have direct contact with the copper vessel, this will then give a true temperature reading with which to control the boiler. The cylinder thermostat is wired to the programmable room thermostat and the control board.
  • The solenoid valve is positioned so that it will allow the hurricane boiler to short-cycle on the calorifier only, therefore normal positioning would have it after the calorifier but before the radiators on a flow and return system. The solenoid is wired into the control board.
