Energy myth-busting: Is it cheaper to have heating on all day?

Some Buildings Insurance policies will not cover for burst pipes if the house has been vacated for an extended period with the heating completely off unless it has been completely drained down.

Ah well its great to know if a pipe bursts whilst you are away for an extended period you are covered by Insurance as long as you have the CH On or your system is 'drained' down!

BTW does the insurance cover pipe repairs or just flood damage?

BTW also do you know what an 'extended period' might be time wise?

Removed because nothing to do with the myth. Sorry.

'a properly cleaned and treated system could be up to 15% more effective at delivering heat in a home than an untreated system.'


03 August 2012

Leading European energy efficiency and water treatment specialist Sentinel has been granted the right to use the Energy Saving Trust’s ‘Energy Efficiency Recommended’ label on its X100 inhibitor chemical water treatment products in the UK following accreditation of its products by the EST. The label will appear on its popular ‘X100’ range of products – on X100 Inhibitor, X100 Rapid Dose, X100 Towel Rail Inhibitor and Contractor Pack Inhibitor.

More efficient at "delivering" heat does not mean it is 15% more efficient. A brand new radiator might output 2,000W. An old dirty scaled up radiator which is 30 years old originally rated at 2,000W might now only deliver 87% of it's rated output 1,740W. Cleaning the system out regularly will stop the radiator filling with rubbish and enable it to continue to output heat at 2,000W. 15% more effective than 87% is 100%. It won't really save much money as the boiler will just run longer to output the same heat. The heat won't disappear it will still be output on other radiators or the boiler will cycle if the return water temperature is too high or if a newish boiler it should modulate the power down a bit to prevent overheating.

What has this has to do with 'The Myth' which is the subject of this thread?

In any case an improvement of 0.0001% is covered by the statement 'could be up to 15%'

Does adding Inhibitor save money?

Fitting a filter , which does a similar job does according to this

In any event, it should your radiators from rusting so will save money there.

As I went on to explain. It will run longer and will modulate the output down to output the same heat but over a longer period of time. A non-modulating boiler will cycle off for a bit to wait until the return temperature of the water is cooler.
