Thanks @BBCRadio4 #YouandYours for flagging our guidance on how save ££ with a few adjustments to your condensing combi boiler

83% of condensing boilers are C-E-Rated in the home, not A-Rated. Equivalent to just 75-85% efficient

Our tips to clawing back some efficiency here🧵

You can safely turn down the heating flow temperature on your *condensing combi* boiler yourself to save 6-8% on your gas bills

You will have a *condensing* boiler if you have a white pipe under the boiler

You will have a combi boiler if you DO NOT have a hot water cylinder

You need to go to the front of your boiler to turn down the heating flow temperature

You are not adjusting your thermostat this time

For more help watch our video on how to turn down the flow temperature on different types of combi boiler

Turning down the flow temp from 80°C to 60°C saves around 6-8% on your fuel bills without affecting your comfort.

72% of homes can stay homes on a January day at 60°C flow temperatures.

If you have a home built after 2000 or purpose built flat try turning it down to 50-55°C

If you have a Worcester, Ideal or Vaillant combi boiler you could save another 5-10% if you turn the hot water pre-heat off. It comes set to on but it's unnecessary in most homes:

If you have a hot water cylinder this is NOT a DIY job

Turning down the flow temp for heating will turn down the flow temp for hot water

This risks legionella in the hot water cylinder
