Internal natural gas hot water cylinders

Iinternal_gas_hwcinternal gas hot water cylinders are always a bit harder to replace because of existing installation conditions. Gas hot water cylinders installed 10 + years ago may not comply to the latest standards. this includes ventilation, flue penetrations, floor base, seismic restraint and several other factors. New products such as the internal Rheem 170L are much more efficient and carry 5 year warranty. What do our installers look for before installing one these models?

  • Ensure the platform is fire resistant (e.g. concrete paver will do it)
  • Ensure there will be sufficient ventilation at lower level and down draft diverter to allow for complete and safe combustion.
  • Check to make sure the existing gas supply pipe is of sufficient size.

    On completion our technicians are required to do a full gas pressure inspection to confirm there are no existing or new gas leaks. Once the installation is complete seismic restraints will attached to secure your new hot water cylinder and finally a gas certificate can be issued that your new hot water cylinder is deemed safe and sound. Hot water cylinder NZ offer various gas hot water solution’s including instant water heating and combination central heating. For more information please call us on 0800 4 Cylinders.

What are Calorifiers?

A calorifier is a heat exchanger which heats water indirectly by circulating it over a heating coil or multiple coils. The source of heat can be water or steam, heated by an external heat source, contained within a pipe immersed in the water. the two bodies of water or steam do not mix. (touch each other)

In hospitals and factories where steam is already being generated for other uses it can also be used to heat the water by the indirect method.

The calorifier may be a continuous coil of pipe or a cylinder within a cylinder with an annular space between the two vessels.

calorifier_design

With the vertical hot water cylinder, the steam enters the coil though the top connection. the strainer or grit trap removes any solid matter suspended in the steam. The steam then passes through the inlet valve which is thermostatically controlled. the thermostat prevents overheating or boiling of the stored water.

A steam trap, fitted near the outlet of the coil, prevents the steam from leaving the coil until it condenses.

In a hot water cylinder which contains a steam coil, the coil must be able to be removed for descaling. this is more likely to occur using steam because the coil is working at a higher temperature than with the conventional hot water system.

Hot water cylinders Ltd provide custom hot water cylinder (storage tanks) design and construction with integrated calorifiers at most demanded KW sizes. Our services include domestic and commercial applications. With water applications heat sources such as Heatpumps, Gas, Solar or steam can be applied.
