“poor technical design adversely affects performance, and ultimately users experience”

Any Megaflo or Unvented hot water installation is unique; it is specified and designed for a particular property, layout and application. As unvented cylinders are supplied off-the-shelf, you generally know what to expect in terms of appearance and capabilities; however, the technical design, specification and general infrastructure are down to the specifier or installer. If this is not implemented correctly, the system will suffer from a decrease in overall performance.

Unfortunately, the infrastructure is where significant cost-cutting and short-cuts can be made; smaller pipes and inferior fittings all contribute to restricting the overall performance. Furthermore, these pipes are typically boxed-in or hidden under floors, so upgrading them can involve major rework, disruption and ultimately costs.

We have seen some appalling installations!  One notable installation, with an upgraded mains supply (installed at considerable costs), simply did not perform to acceptable standards. When using water in the kitchen (washing machine, tap, dishwasher, etc), the flow at any other outlet was substantially reduced! The under-sized pipes were laid under a tiled floor, and under the kitchen units!

The makeshift solution was avoiding any other water usage whilst the showers were in-use! Although inconvenient, this worked as long as the dishwasher or washing machine were not already running…

A poorly designed system may suffer from any of the following symptoms:

Although we have seen many illegal installations, the problems mentioned above, refer to technical design and installation issues, rather than safety and legal conditions imposed by the G3 Building Regulations. We would strongly advise that any Megaflo or Unvented Cylinder installation is carried out by a suitably competent person or company, qualified and registered to comply with the current G3 Building Regulations.
