A house is designed to have passive solar energy features. Brickwork is to be incorporated into the interior of the house to act as a heat absorber. Each brick weighs approximately 1.8 kg. The specific heat of the brick is 0.85 J/g·K. How many bricks must be incorporated into the interior of the house to provide the same total heat capacity as 1.4 x10 ^3 gal of water?

A man who repoints and restores brickwork told me that sandblasting bricks is a bad thing to do. He said its bad for the brick work, although it does make bricks nicer in appearance. I am wondering WHY this would be harmful to your brickwork?

I'm going to need about a dozen ordinary house-bricks for a job in the house, but am not sure whether how they are sold. Is it possible to buy bricks individually (or in small amounts) or do you have to buy them by the gross or something. I don't want to go on the thieve from a local building site for the few bricks I need, but if I can't buy just a few rather than loads I might just have to. Anyone have an idea of price per brick. Pennies, surely? There's a few American answers here, so I'll just add that yes I am in the UK. I just need some bricks (any bricks as long as they are all the same) to support the shower unit base that we are putting in the bathroom. We've been under the impression that places like B&Q, Wickes, Homebase etc, sell by the hundred or whatever and not smaller sales. Its good to see most people disagreeing and saying you can buy as many or as few as you want. There are several good answers here.

The bricks are all breaking in the woodstove and I'd rather change the bricks then change the stove. Any ideas? Thanks.
