Which type

What suits your house

Most hot water disappointment comes from the wrong type or the wrong size, not from a bad install. Here’s the honest version of each.

New Rheem storage hot water system installed outside a brick home with copper pipework

Gas storage

A tank kept hot by a gas burner. Cheap to run where mains gas is connected and it recovers quickly, so it suits families who all shower around the same time. It takes up outdoor space and the tank itself has a finite life.

Thermann gas continuous flow hot water unit wall mounted on brick with copper pipework and isolation valves

Gas continuous flow

Heats water only as it flows, so it never runs out and there is no tank sitting there losing heat. Wall mounted and compact. The catch is that flow rate is limited, so running two showers at once needs the right size unit.

Electric storage hot water system installed outside a brick and tile home

Electric storage

Simple, cheap to install and common on homes without mains gas. Running cost is the downside unless it is on a controlled tariff or paired with solar. Element and thermostat faults are usually repairable.

When it dies

What actually goes wrong

Hot water units fail in a small number of predictable ways, and knowing which one you have is the difference between a part and a new unit.

  • No hot water at allOn electric, usually the element or thermostat. On gas, often the thermocouple or igniter. All repairable parts.
  • Runs out too quicklyEither the unit is undersized for the household, or a failing element means only part of the tank is heating.
  • Water not hot enoughThermostat, or a tempering valve that has worn and is mixing too much cold through.
  • Leaking from the bodyThe tank has corroded through. No repair exists for that, and it will get worse quickly.
  • Constant discharge from the relief valveA worn valve, or excessive mains pressure. Cheap to fix and worth doing, because it’s wasting water constantly.

FAQs

Hot water questions

How do I know if it’s worth repairing?

Age and what has failed. An element, thermostat, valve or thermocouple on a unit under about ten years old is usually worth fixing. A tank that has rusted through and is leaking from the body cannot be repaired at any price — that is the end of its life, and anybody telling you otherwise is stringing it out.

There’s water dripping from a pipe on the side. Is that a fault?

Not necessarily. Storage units are meant to discharge a small amount from the relief valve as the water expands while heating. A constant stream or a steady flow is a fault. Water coming from the bottom of the unit itself usually means the tank has gone.

Can you replace it the same day?

Often, yes. We carry the common sizes and types, so a lot of failures get replaced the day you ring. Less common units or a change of system type may mean ordering in, and we’ll tell you which on the phone.

Should I switch to continuous flow?

It depends on the household. Continuous flow never runs out and takes up less space, which suits people who shower at staggered times. Large families running two showers at once need a properly sized unit or they’ll be disappointed. We size it on how the house actually uses water rather than on what is easiest to fit.

What is a tempering valve and do I need one?

It mixes cold into the hot supply so water reaching bathroom outlets is delivered at a safe temperature, which matters most with children and older people in the house. It is a standard part of a compliant installation and it does eventually wear out and need replacing.

Can I move the unit somewhere else?

Sometimes. It comes down to where the water and gas can run, where the relief line can discharge and what clearances the unit needs. We’ll work out what’s possible on site before quoting rather than after.

How do I make it last longer?

Have the sacrificial anode checked every few years on a storage unit. It is a cheap part designed to corrode instead of the tank, and replacing it can add years. Almost nobody does it, which is why so many tanks fail early.
