Everything you need to know about our CombiSave

Watch our short video to learn more about our CombiSave, how it works and why getting one could help with your hot water.

How a CombiSave could help you

Have you got a combi boiler (one that heats your water as you need it, instead of using a water cylinder)? Here's how a CombiSave can help you save time, money and water.

Save water

Save up to 28,000 litres of water (that's almost 350 baths) and 600kWh of gas (enough to power the average home for two weeks) a year.

Get hot water faster

With a CombiSave, it takes around 30 seconds fewer for hot water to reach your taps - cutting your waiting time by up to 50%.

Lower your bills

Reducing the amount of gas and water you use with CombiSave helps lower your gas and water bills (if you're on a water meter) by around £100.

How does a CombiSave work?

A CombiSave is a simple valve that monitors your water temperature. It's fixed under your combi boiler, using existing pipework.

  • When you turn on your hot tap, the CombiSave slows the water flow until it heats to the right temperature (around 43°C)
  • Once the water is nice and hot, you'll notice that the flow to your tap or shower goes back to normal
  • As it's just a valve, it doesn't use any extra gas or electricity

Do I need a CombiSave?

A CombiSave is right for you if:

  • You have a combination boiler (a boiler without water cylinders or storage tanks)
  • You have a water meter
  • You're tired of waiting for hot water every time you turn on a tap or shower

How quickly can I get hot water using a CombiSave? Is it safe?

If you've got a combi boiler, it can take up to a minute for your hot water to get to the right temperature – that's a wait of around 21 hours a year! With a CombiSave, you'll cut your wait time by up to 50%. On average, it takes around 30 seconds fewer for the hot water to get to your taps. You'll notice an increase in flow once the water heats up, but don't worry, your taps won't suddenly start bursting with hot water.

I live in a big house. Do I need just one CombiSave?

Yes — you only need one CombiSave per boiler — no matter how big your house is.

I already have a CombiSmart. Do I need a CombiSave?

No — a CombiSmart gives you the same benefits as a CombiSave so you don't need both.
