Hi All ,

I'm new to this , so apologies if already been covered .

Have a Potterton Suprima 70L boiler which has always run at max temp using single black dial inside control panel as originally advised by fitter .

Due to the cost of living / fuel crisis can I save money by turning down somewhat , and what is the ultimum recommended setting for both efficiency and cost ?

From what I've read, it's minimum setting is 57°c and it's max 82°c.

Govt are advising turning boiler temperature down to 60°c to save money ? If I turn dial down I'm guessing it will take longer to heat radiators or they won't be as hot , so it seems I may lose effectiveness of heating our very cold/damp house in order to possibly save a few quid ? On the other hand , is running it on max just wasting unnecessary gas which escapes from the outside flue as its a conventional non condensing boiler ?

The water temp is set at 60°c as far as I know off a seperate controller on side of water tank .

Any advice gratefully received.

Many thanks .

Hi Andrew .

Not sure quite what you mean but there's a hot water tank in the downstairs airing cupboard and a red expansion vessel connected to the boiler if that helps? Everything runs off the gas boiler but I believe the water temperature in the tank has its own temperature control on the side set to 60°c.

As often happens the Gov advice can get a bit muddled.

A condensing boiler works more efficiently with a lower flow temperature.

Your old non condensing boiler is only slightly more efficient with a lower flow temperature.

The Gov advice should also say turn down your room thermostat to about 19C and learn to live with a lower room temperature and wear a pullover to feel more comfortable.

To heat the hot water to 60C you really need your boiler flow set a little higher and at perhaps 65-70C.

But you could probably lower your hot tank setting to 55C without noticing any difference. Then the boiler flow to about 65C
