Morco Products Ltd is a UK supplier of LPG heating and hot water appliances, with roots going back to a marine chandlery business founded over 200 years ago and over 70 years supplying its own branded LPG heating and hot water solutions1. For a household preparing for emergencies, that matters: an LPG appliance keeps working when the mains gas or electricity supply fails, as long as the gas bottle holds out.
The products this site mentions
The Primo Gas Water Heater and the EUP Gas Water Heater are open-flued LPG water heaters that may be installed in mobile homes, caravans and domestic settings2. They heat water instantly as it flows, so a household with one can wash and fill hot water bottles even during a power cut, when an electric immersion heater or a mains combination boiler cannot run. Around 23.9 million (82%) of UK homes have gas boilers for heating and hot water, and those boilers need an electricity supply to operate, so households that rely on them lose hot water in a power cut3. An LPG water heater on a bottle does not have that weakness.
Morco also makes the GB24 IV and GB30 IV, wall mounted, room sealed, condensing combination boilers with automatic spark ignition and fan assisted combustion, providing central heating and instantaneous domestic hot water4.
What to know in an emergency
A working LPG water heater can supply hot water during a power cut, but only if it is a model outside the recall above. Check the model and serial number against the recall notice before you rely on it, and do not use a recalled heater under any circumstances.
If you smell gas, Morco's own instructions are to contact the gas supplier without delay and turn off all gas supplies4. Any installation or repair must be carried out by a Gas Safe registered engineer: it is the law that Morco boilers are installed by a registered engineer in the UK, and every registered engineer carries an ID card with their own unique licence number and a photograph4.
Morco offers a 5 year parts and labour warranty from the first commissioning date on its GB24 IV and GB30 IV combination boilers from serial number AHN onwards, for appliances located in Great Britain or Northern Ireland, and activation by registration is required4. The maker's website, morcoproducts.co.uk, carries the latest literature for specification, maintenance and parts replacement, and includes a guide to finding your model and serial number so you can check the recall list4.
