Power Shower FAQs — London
What is a power shower and can I have one in my London home?
A power shower has a built-in pump to boost gravity-fed (vented cylinder) systems. Required where a loft cold water tank provides only 0.1–0.3 bar. Not compatible with combi boilers or unvented cylinders — these are already at mains pressure and a pump would create a dangerous over-pressure.
How do I know if my London property is compatible with a power shower?
Compatible: hot water cylinder in airing cupboard + cold water tank in loft + current shower is low-pressure. Not compatible: combi boiler, unvented (Megaflo) cylinder, or electric shower. About 40% of London pre-1990 terraces still have gravity systems — ideal for power showers.
What are the best power shower brands for London properties?
Aqualisa (best scale resistance for London hard water), Mira (Sport Max and Event XL — anti-scale technology), Triton (value option, good parts availability in London). Annual descaling of shower head and pump impeller is important in London's 280–320 mg/l hard water.
Why does my power shower lose pressure in London?
Most common: (1) Scale-blocked shower head — soak in vinegar. (2) Scale-blocked pump impeller — annual service. (3) Low loft tank level — check cold water tank ball valve. (4) Scaled shower cartridge — replacement £95–£150. London hard water blocks pumps 3–5× faster than soft water areas.
Can I fit a separate shower pump instead of a power shower in London?
Yes — and we often recommend it. A Stuart Turner, Grundfos, or Salamander pump fitted in the airing cupboard lasts longer than a pump inside the shower unit, is easier to service, and is compatible with higher-specification thermostatic shower valves.
How much does power shower installation cost in London?
Power shower unit supply and install: £250–£500. Separate pump install: £280–£600. Annual service and descale: £85–£130. Pump replacement: £200–£450. Cartridge: £95–£150. Alternative: unvented cylinder or combi upgrade (£1,800–£3,500) eliminates the need for a pump entirely.
