I think rocket stove is the american name for them though I could be wrong. Ive always known them to be called norwegian stoves or just mass ovens.

What do you want to know? Ive built a couple of them, mainly out of earth and fire bricks]]> Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=85945#Comment_85945 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=85945#Comment_85945 Mon, 26 Jul 2010 09:54:14 +0100 SteamyTea ]]> Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=85951#Comment_85951 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=85951#Comment_85951 Mon, 26 Jul 2010 11:28:03 +0100 MikeRumney He's going to advise me via email initially and maybe visit for a "workshop" on site when we've got the design sorted.
Also waiting to hear back from "Nordpeis" who make these (listed on "stovesonline") to see if they will supply just their door, or door+firebox, in order for me to build the rest around it.

There are various ways of running the channels through the masonary, some of which seem to need more in the way of access for cleaning ... and smart design to avoid gas pockets (using channel to channel vent holes)
Broadly speaking these are variations on going for either long vertical channels, or lots of short horizontal channels, or a combination ... Preferences anyone?
Would a spiral combine the benefits of both??

Our (single storey) layout is as on the first pic.
Each angled off corner once had a fireplace, and the two double-stacks remain.
The dimensions of what we have to work with for the mass stove in the second pic (posted separately)
The idea is to take down the front wall of the living room fireplace (pink) and "fill-in" behind.
There would be double the space/mass available if we can link to the adjacent space (between green & blue) ......]]> Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=85952#Comment_85952 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=85952#Comment_85952 Mon, 26 Jul 2010 11:29:02 +0100 MikeRumney Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=86338#Comment_86338 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=86338#Comment_86338 Tue, 03 Aug 2010 13:29:48 +0100 crusoe Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137547#Comment_137547 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137547#Comment_137547 Wed, 29 Feb 2012 22:02:32 +0000 daveseavista
This link look good on this type of heater.

Been looking at the 45 gall drum rocket room heaters with hot plate on top. Do you know how critical the gap is between rocket tube end and the base of the hot plate. I have tried to get distances but hove only found a couple of references of 1.5 to 2 inches.]]> Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137592#Comment_137592 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137592#Comment_137592 Thu, 01 Mar 2012 09:58:08 +0000 JSHarris Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137638#Comment_137638 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137638#Comment_137638 Thu, 01 Mar 2012 14:11:51 +0000 Phil.Chaddah-Duke ]]> Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137657#Comment_137657 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137657#Comment_137657 Thu, 01 Mar 2012 17:38:24 +0000 Peter_in_Hungary Posted By: renewablejohnI always thought rocket stoves and masonry stoves were two distinct technologies.

They are - unless the rocket stove is made out of brick, then pretty much the same - a solid fuel storage heater

Posted By: Phil.Chaddah-DukeThese are cool, never seen them before. Oh well something else added to the To Do list, wondering if I could make one heat our Thermal Store


Both rocket stoves and masonry stoves are essentially space heaters, which can be fitted with wet heat exchangers at the building stage. The heat exchange coils are usually used to feed a couple (or 3 or 4) rads that are remote from the stove. IMO not really suitable for heating a TS as the ratio of heat to water and heat to air is very much biased towards the air. In any case the masonry stove or rocket stove built of brick is a dry TS (albeit with an uncontrollable output once firing has finished) so would you want to transfer heat from one TS to another. If a metal rocket stove was heating the TS I don't think I would want to be in the same room as again the heat output would be very much biased to the air rather than the water.]]> Rocket Stove Mass Heater https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137765#Comment_137765 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=6072&Focus=137765#Comment_137765 Fri, 02 Mar 2012 11:29:11 +0000 Phil.Chaddah-Duke http://milkwood.net/2009/07/12/the_rocket_powered_shower/
Would like to see it in operation, wonder if is as efficient as the traditional horizontal designs?]]>
