“poor technical design adversely affects Megaflo performance, and ultimately users experience”
All Megaflo or Unvented hot water installations are unique; they are 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 is the responsibility of the the specifier or installer. If this is not implemented correctly, the system will suffer with a decrease in overall Megaflo performance.
Unfortunately, the infrastructure is where significant cost-cutting and short-cuts can be made; smaller bore pipes and inferior fittings all contribute to restrict the overall system performance. Furthermore, these pipes are typically boxed-in or carefully hidden beneath the floors. This is fine until subsequent rectification works are required which often involves major rework, disruption and ultimately costs!
Sadly, some noteable installations come to mind. One, had a new larger water main installed at considerable costs, but still the poorly designed system had no chance of even delivering ‘acceptable’ performance! When drawing water within the kitchen (washing machine, tap, dishwasher, etc), the flow at any other outlet was halved! The under-sized pipes were laid under a tiled floor, and under the kitchen units! One solution, was a strict house rule making the kitchen area out of bounds whenever the showers were being used! How inconvenient is that? This helped as long as the dishwasher or washing machine wern’t already running…and intermittently drawing water!
Use Apex Plumbing and Heating, and get it right first time.
A poorly designed system may suffer from any of the following symptoms:
- Reduction in flow or pressure when another appliance or tap is used; particularly noticeable with showers.
- Poor flow rates from all or some outlets.
- Rattling or noisy pipes.
- High velocity water noise within the pipes.
- System loses pressure
- Initial burst of high pressure and then pressure drop off.

Although we have seen many illegal installations, the problems mentioned above, refer to technical design and installation issues, rather than the safety and legal conditions imposed by the G3 Building Regulations.
We 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.
