Traditionally, a low pressure hot water cylinder was an open-vented system providing hot water supply for most homes in Auckland, New Zealand. They are reliable and provide hot water, however only limited pressure, so with the modern expectation of great showers, rather than just the old school bath, low pressure hot water cylinders have become a lot less desirable.
Regardless of peoples expectations for high pressure showers and good pressure in the kitchen sink, we still install many low pressure hot water cylinders in low cost homes, rental properties, business premises, and farm buildings, as often the low cost appeals to those who do not feel it a requirement to upgrade to a mains pressure cylinder.
Can you upgrade the pressure of your low pressure hot water system with valves?
The answer is yes, however be aware this will be only a slight improvement and reduces the life of your old low pressure hot water cylinder.
