I wish I had a thermometer. Radiator experiments are unsatisfactory without one.

I'll Google to see if Poundland sell them.

They do!

There's not a lot of information about it.

Isn't that a body temperature one?

It doesn't say.

It shows 37°C, and it's in the baby care section.

Oh.

And it's got a pointy end.

I've just put some of that film, that turns your double glazing into triple glazing, on my window. I wonder if it'll really work? And will the difference be noticeable?

That’s for the ear.

I've set my radiator flow temperature to 30 degrees to see what happens.

I've had it at 30 degrees for the last three days, with every radiator in the house on full, the hallway thermostat at 18 degrees and the heating on for 24 hours a day. The house is perfectly comfortable in every room and, yesterday, it cost me around £5.45 in gas.

Today, the third day of this experiment, it's on course to cost just £4.11.

Admittedly, this is roughly £1 a day more than it was costing before. Then, I only had the heating on in my bedroom and the bathroom and just had it on for 2.5 hours a day, with the flow temperature set to 75 degrees. So, given that I'm heating the entire house, all day long, the increase in cost is far less than I'd expected.

What was the radiator flow temperature before? I would have thought it would be about 60 degrees?

I had it at 75 degrees. I don't believe in messing about.

Well, I am just a modern guy, of course I've had it in the ear before.

I've now kept the same conditions as the past three days but turned off the radiators in every room apart from my bedroom, the bathroom and the hallway, to see how it compares with having all the radiators on.

Heating just the bedroom, hallway and bathroom for 24 hours, with the flow temperature set at 30 degrees, cost £1.68 yesterday. My main thermostat is set at 18 degrees.

My boiler doesn't store water in a cylinder. It heats it as it passes a heating plate thing.

Also, I have my tap water set at 60 degrees. Only the water for the radiators is limited to 30.
