Heat loss

Despite taking the usual measures I am convinced our house is a lot colder than it should be and I wondered if it was possible to either hire or get access to a thermal image camera.
Any other ideas on how I might check heat loss would be useful

You could also approach the problem from the 'other end' and try measuring inside surface temperatures to find 'cold spots', any electronic thermometer with a surface temperature probe should suffice for this.
Or possibly one of these might allow you to do a 'survey' inside and out.
[Edit] found this if anyone wants to get into thermal imaging at a (comparatively) reasonable cost.

Failed windows and door seals? They go hard with age.

Re: Heat loss

@nozzer,
We recently had these replaced but even with new seals there is no guarantee they are ok but I have ordered a item identified by Mav which will allow me to check them.
@Mav,
Thanks for the links, the feedback on the item from Maplin sounds right up my street at £19.99 and it comes with free postage.
I can see a few other useful uses for this item.
The professional ones for hire are likely to be much better but the cost of hiring one is a bit above my budget.
Thanks for the responses.

Re: Heat loss

I've got one of those Maplin infra red temp sensors in my tool box.
I use it for measuring the temperatures in suspect motors, brake units, batteries etc.
It's a decent bit of kit for the price.

I blame age, the older a person gets, the higher the thermostat tends to go, but they still feel cold, it's as though we become cold-blooded creatures as we head into the grey years... Shocked

How is it constructed? Solid brick external walls, or cavity, and how old is it?

Re: Heat loss

@nozzer,
Built 1987, cavity walls with some sort of insulation which look like small polythene balls.
I am a bit suspicious about the floor, which is a solid ? bitumen floor and a number of years ago I put down some laminated floor boards with a carpet square in the middle, should that turn out to be the problem then I am stuck as the only answer would be to put a fitted carpet down which defeats the object of a laminated floor.
Hopefully the item ordered from Maplin with confirm that one way or another.

Re: Heat loss

That should be quite good thermally. I wonder if you are suffering from poor flow to the radiators? Do they all seem to be getting hot top to bottom when the system is working hard? Especially bottom?

Do, please, let us know how you get on.
How much insulation do you have in your loft?  Often well worth topping up if less than about 10 inches.
