GL Hot Water Cylinders
Adveco GL is a range of glass lined commercial and industrial hot water cylinders for vented or unvented DHW applications, covering 200 to 3000 litres, including 500 litre and 1000 litre models, across three configurations, GLE, GLC and GLT. Built from a carbon steel shell with an enamelled inorganic lining up to 1000 litres, or a blue epoxy powder coat lining from 1500 litres upward, GL cylinders are rated to working pressures up to 8 bar and temperatures up to 85°C, and carry both WRAS and Kiwa KUKreg4 certification.

Options
Adveco GLC
With a single fixed indirect heating coil, the Adveco GLC range of calorifiers is designed to serve as indirect water heaters or preheat vessels. Available in 200 to 3000 litres capacities, the Adveco GLC features a single fixed indirect heating coil at low level and can also accept a 180mm 3-36kW electric immersion. The coil has a maximum working pressure/temperature of 10 bar / 110°C.
Adveco GLE
Available in a range of sizes from 200 to 2000L, the Adveco GLE is designed to serve as a buffer vessel or an electric water heater. Compatible with a wide range of direct electric immersion heater options available from Adveco, the GLE supports duty immersions from 3 to 36 kW, as well as secondary supplementary immersions from 3 to 6 kW for additional heating, or as backup to ensure continuity of service from a single unit.
Adveco GLT
The Adveco GLT range of calorifiers is designed to serve as indirect water heaters. The tanks, available in 200 to 3000 litres capacities, incorporate two fixed indirect heating coils, one each at low and high level, designed for use with two separate heat sources.
All vessels also include a cleanout flange, a magnesium sacrificial anode (pre-fitted in 300-1000L variants), and a temperature gauge as standard (pre-fitted in tanks up to 1000L). They include a tough PVC jacket enclosing rigid high-density polyurethane foam or removable polyester fibre insulation. The jackets and insulation are pre-fitted for tanks up to 1000L.
The Adveco GL range of tanks carries both WRAS and Kiwa’s KUKreg4 certification of product compliance with the water supply (water fittings) regulations for England, Scotland, and Northern Ireland.

What is a glass lined hot water tank?
A glass lined hot water tank uses a fired enamel or powder coat glass lining fused to the inside of a carbon steel shell to stop the water in contact with the tank corroding the metal. Adveco’s GL range uses an enamelled inorganic lining on tanks up to 1000 litres, and a blue epoxy powder coat lining from 1500 litres upward, giving a cost effective alternative to stainless steel construction while still holding up to the water conditions found across the UK.
Multi coil and double coil cylinders
GLT is Adveco’s multi coil, or double coil, cylinder in the GL range, fitted with two independent indirect heating coils rather than one. That lets two separate heat sources, commonly a heat pump on the lower coil and a boiler on the upper coil, run into a single vessel rather than needing two separate tanks. GLC covers the single coil equivalent where only one indirect heat source is required, and GLE drops the coil entirely for buffer or direct electric duty.
Sizing and available capacities
GLC and GLT both run from 200 up to 3000 litres in the same size steps, 200, 300, 500, 750, 1000, 1500, 2000, 2500 and 3000 litres, so a like for like size is available whichever coil configuration you need. GLE covers 200 to 2000 litres within the standard datasheet, with larger 1500 to 5000 litre models, including sizes such as GLE4000, covered under a separate datasheet for higher capacity buffer and electric water heater applications.
Destratification and controls
Every GL cylinder can be specified with a destratification pump kit (MB0001), which keeps water temperature more even through the tank rather than letting heat stratify at the top, alongside a control thermostat and overheat thermostat as standard ancillaries. A magnesium sacrificial anode and temperature gauge are included as standard, pre-fitted on tanks up to 1000 litres.
