Gas Safety Check/Inspection and Test
An inspection and test involves a visual inspection of gas installation- flexible hoses, pipework, pipe unions, fittings, and appliances to check identify any corrosion or defects, a check of the gas locker to ensure it will drain safely overboard, and a pressure test to ensure no leaks and demonstrate soundness of system. Any appliances are lit to ensure they are working correctly and our gas safety record is issued, along with recommendations to bring the system up to best practice if appropriate. A wide range of parts are carried so any faulty parts can be replaced on the same visit if requested.
Cookers often suffer from corrosion, particularly in a marine environment resulting in common issues such as poor/yellow flames causing sooting and carbon monoxide emission, seized cooker control valves and burners not staying lit due to thermocouple failure.
Parts are available for most makes of marine cooker making servicing a viable option and in many instances replacing detective parts can be done at a faction of the cost of a new cooker. Often the cooker does not have to be removed from the vessel and common parts are carried in stock.
Since LPG is heavier than air if there is an internal leak it will sink to the lowest point. An alarm will detect and give warning of an accumulation of gas. The alarm may be linked to a solenoid valve to automatically shut off the gas supply in the event of gas detection.
Supply and install of alarm systems including-
Nereus supply a range of gas alarm systems designed specifically for marine usage for detecting LPG (butane/propane). They are more expensive than some alternatives but are one of the only systems that use waterproof sensors (IP55 and 57 rated). Since LPG is heavier than air sensors should be located in the bilge and non-waterproof sensors are frequently damaged by bilge water. They operate at a very ow power consumption and the control panel indicates power, fault and and alarm conditions.
A cheaper alternative marine LPG detection system but sensors are not waterproof so it is recommended that these are fitted only if you are confident your bilge is dry!
Propex Heat Source heaters are automatic thermostatically controlled blown air heating systems fuelled by propane or butane gas. They are designed for a variety of automotive and marine applications as a source of heat independent of the engine and are well suited to fit on boats or in vans.

Design and installation of bespoke systems to suit your needs and usage; fitted to British or European Standards BS5482-3 2005 or EN ISO 10239.
Depending on your requirements installations may include a combination of the following:
- Single or multiple bottle systems with changeover valve.
- Propane, Butane or multi fuel regulators, bottle or bulkhead mounted
- Different bottle type adapters
- Gas locker
- Electrical isolation solenoid to allow remote shut off of gas supply at the bottle
- Copper pipework, fittings and flexible hoses
- Gas alarm
It is recommended that:
- Coded vessels are serviced annually
- Privately owned vessels carry out a visual check of hoses annually, and flexible hoses should be changed every 5 years, regulators changed every 7-10yrs, fittings, and cooker isolation valves fitted to older vessels.
(It is always worth checking your insurance terms as these may specify servicing/test and inspection frequency)
