General Spares
Overview
As well as manufacturing goods, GMS are also able to supply spare and replacement items for your systems such as immersion heaters, gaskets, thermostats, valves, pumps as well as tube bundles and headers.
Immersion Heaters
GMS use electric immersion heaters as an alternative heating source as it requires low installation, maintenance and has low off-peak costs. It can also be a cost effective back-up for other heat sources during periods of low demand and shut-down of the main primary heating source. Electric Immersion Heaters are used as the main source of heat in our Electric Storage Calorifiers

Tube Bundles
U-Tube batteries are the most common method of heat exchanger for use with calorifiers. The battery consists of a number of ‘ U-tubes’ expanded into a tube plate. The tubes and tube plate can be manufactured in a variety of materials to suit the shell material and application.
GMS can design U-tube Bundles based on kilowatt rating, primary temperatures available and the secondary temperatures required. Tube bundles can be designed and manufactured for new installations or can be designed as replacement items suitable for existing units.
Replacement Gaskets
Replacement gaskets can be provided in NBR, EPDM or NOVUS materials. Gaskets can be provided for headers, flanges, and inspection openings. If the replacement gasket is for a GMS unit all the information that we require is the original contract reference. If the gasket is for a ‘non-GMS’ unit we will require a template or details regarding the PCD, overall diameter, thickness required etc. Our sales department will be more than happy to help you with your enquiry.
Unvented Kit
We quote all of our unvented cylinders with an unvented kit, however if you forgot to order one or just need a couple of spares GMS can provide a quotation for the correct unvented kit that you require.

We can also offer alternatives if you require a different specification
Expansion Vessels
Expansion vessels are commonly used to protect closed water heating systems and domestic hot water heating systems from being exposed to high pressure. Expansion vessels work by being part filled with air, this then protects the system by cushioning any shock which is caused by water hammer and also absorbing any excessive water pressure which may have been caused by thermal expansion.
GMS supply two types of expansion vessel
· Heating Expansion Vessel
· Potable-Water Expansion Vessel
