About Cord & Tank

Cord & Tank does the heating sums: what a cord holds, how long a tank lasts, and which fuel gives the cheapest heat at your prices.

What the site does

It turns the official figures for each fuel into calculators you can use with your own measurements and prices. Pages with figures list where each one comes from.

Who it's for

Anyone in the US buying firewood, propane, heating oil or pellets, or comparing one fuel with another.

How it's paid for

For now it isn't: there are no ads and nothing for sale. If ads are added later, they will never change a figure or a result.
