Common Cylinder Faults We Fix

No Hot Water

Faulty immersion heaters, broken thermostats, or timer issues? We diagnose and restore your hot water quickly.

Leaking Cylinders

Puddles around the tank? We fix leaking valves and pipework, or advise on safe replacements if the tank has split.

Low Water Pressure

Struggling with a weak shower? We can upgrade your traditional gravity-fed system to high mains pressure.

Noisy Tanks

Banging, bubbling, or hissing sounds coming from the cylinder? This usually indicates scale buildup or trapped air.

Unvented vs Vented Cylinders

Understanding what type of hot water tank you have—or what you need—is the first step to an efficient, powerful water system.

Unvented Cylinders (Megaflo)

Modern, high-performance systems connected directly to the mains water supply. They deliver hot water at high pressure to all taps and showers simultaneously.

  • Exceptional mains water pressure
  • No cold water storage tank needed in the loft
  • Highly insulated for energy efficiency
  • Requires specialized G3 certification to install

Vented Cylinders

Traditional copper cylinders fed by a cold water tank in the loft. They rely on gravity to push water around the house, common in older properties.

  • Reliable, tried-and-tested technology
  • Generally cheaper to replace and maintain
  • Perfect for areas with low mains water pressure
  • Can be upgraded with shower pumps

Our Installation Process

1. System Sizing

We calculate your household's hot water demand to recommend the perfectly sized cylinder (e.g., 150L to 300L).

2. Safe Removal

We safely drain, disconnect, and remove your old cylinder and loft tanks (if upgrading to unvented).

3. Expert Fitting

Our G3 qualified engineers install the new cylinder, connecting the pipework, thermostats, and safety valves.

4. Certification

We test the pressure, balance the system, and provide you with the necessary legal safety certificates.

Why Trust Us With Your Hot Water?

Hot water cylinders operate under intense heat and pressure. Incorrect installation isn't just inefficient; it's dangerous. Always use certified experts.

G3 Qualified Engineers

It is illegal to install an unvented cylinder without a G3 qualification. Our team is fully certified.

Energy Efficient

We install modern, highly-insulated cylinders that minimize heat loss and lower your energy bills.

Fast Emergency Response

Left with no hot water in the middle of winter? We prioritize no-heat callouts to get you sorted fast.

Extended Warranties

Many of the premium stainless steel cylinders we install come with up to 25-year manufacturer warranties.
