Use storage heater bricks to dog house

Bethal_2

Hi


I have read about people putting old storage heater bricks on a fire then wrapping them in a towel and using as a hot water bottle. I wondered if anyone knows if the following is possible?


I have (will have soon) an outdoor summer house which is insulated and will be used as a dog house. I want to be able to heat a storage heater brick in my woodburner whilst it is used in the evening. I then somehow want to put this brick in an insulated box of some sort (perhaps made of Vermiculite - guessing here?!) so that the brick will retain its heat until the next morning. I then want to transfer the brick into the dog house as a heat source. Obviously safety is a concern. I would want to utilise the heat from the brick but don't want the dogs to burn noses, paws etc.


Any ideas would be most welcome.


Many thanks.

Step zero is to work out how much heat you need, before trying to work out how to heat it.
A heated pad may be lots easier.

How large is this summer house, and is it very airtight?

As some ballpark numbers.
A brick weighing 2kg will store about 1watt-hour of heat per 2C rise.

So, heating it to 400C will release 200 watt-hours of heat - or equivalent to over 8 hours 25W or so.

Hi

Put a brick in my log burner then wrap it in a towel it'd be a case of bye-bye towel .... place it in the doghouse and you might as well say goodbye to that too, before handing yourself in to the RSPCA ...

The skin temperature of the outside of our burner is usually hotter than the maximum temperature of our oven and the fire-bed has been known to get hot enough to reduce high quality glossy paper into a layer of clay before firing it into lumps of rough china ..... don't put anything like that hot anywhere near combustible material, children or pets!

We've got a small (Le Creuset) kettle which sits on or near the log burner for almost on-tap hot drinks and would have thought that using one to fill an old fashioned pottery HWB (which could be wrapped in a blanket) would be a better option for your too .... much safer proposition altogether, plus you get immediate access to hot drinks throughout the day !!
