Self-priming cylinders and combination units are single feed indirect water heaters for use in open vented hot water systems in conjunctions with a central heating system. They don't require a primary feed and expansion tank and, as a result, reduce installation costs. The cylinders are available with compression fittings. Extra tappings and immersion heater bosses can be fitted dependent on individual requirements. Self-priming cylinders are not suitable for fully pumped systems.
