Last month I wrote about early steam heating and how experimentation led to discovery, which led to new products or piping techniques. This time I will be writing about the early days of gravity hot ...

The pipes that snake out from a hot-water or steam boiler and from a water heater radiate heat much like a conventional radiator or baseboard. You might welcome that heat if you spend a lot of time in ...

Which can move heat faster: a few heat pipes (say six 6mm pipes) or water running through a tube? Careful: I'm trying to zero in not on whether a heat pipe setup or a water cooling setup is better for ...

When you think about it, there are quite a few different things that we run into when we look closely at an installed radiator. Frequently overlooked, that thing can make a big difference in the ...

Conventional district heating systems are generally designed around the load. However, an alternate approach would be to design around potential heat sources, including the waste heat from power ...

The world’s largest geothermally heated hotel, which happens to be connected to the world’s largest mineral hot springs pool, is in the middle of a major upgrade to its 30-year-old heating system.

The author’s woodstove is plumbed to a recycled water heater that sits above the stove, allowing the thermosiphon effect to circulate water between them. For years, we’ve been experimenting with ...
