Typical tank and vessel heating systems are compared in this table and as illustrated. Budget prices for heaters are also listed. Cost of mounting flanges, heater controls and fitting should be added. We strongly urge our Customers to contact our Engineers at earliest project stage, so we can assist you with heat calculations, design and specific costs.

Stored liquids often needed to be heated, to prevent freezing, to improve flowability or to achieve a process reaction. Heating medium can be hot oil, LP or HP hot water, or steam. Or electric power. Heating can be by IMMERSED elements or coils. Or EXTERNAL jackets, limpet coils, heater 'pads' or electrical trace heating. Choice of heating method will depend on:-
- Available source of heat - electric , hot/water/steam, hot oil (thermal oil).
- Product susceptibility to 'overheating' carburisation.
- Maintenance and hazardous area considerations.
- To prevent heat loss (and running costs arising), tanks should be thermally insulated and weatherproof clad. See Integ List No. 90 for details.
