Boilers ...Kind of a cross-over with Spicey's wood-burning cooker thread, but didn't want to hijack it ...How big is a 100,000BTU backboiler? If a stove has one that will produce 100,000BTU over 24 hours (which the spec says), is that enough for any rads? Or just DHW? Just askin'. Not thinkin' about getting a different rayburn. 'onest. |

1 watt is approximately 3.41 BTU/h.
If the marketing material is correct they're syaing the stove produces 100,000 BTU's in 24 hr period so an average that's 4,166 BTU/h which is 1.2KW. I'd say that was enough for DHW. The Rayburn 212SFW is rated a 12,000 BTU (3.5kW) per hr and is designed for DHW and partial central heating. |

Never seen any advetised as x BTU per 24 hours. Most just quote BTU. 100k btu will do DHM plus a large house. Our current oil boiler is 120k btu & does 26 rads. Remember solid fuel boilers work differently to oil ones. Once its lit all the heat must go some where so plan on having a heat store too. Will even out the heating demand & supply.

It is unusual makes me wonder if it's marketing blurb to make their boiler sound more powerful than it really is (by a factor of 24). |

Hmm, no, don't think so - it's the specs for the Rayburn No. 3 on the Rayburn website: Here. Maybe fifty years ago the way output was described was different? Am eyeing one up that we've seen on eBay. Quite worried that the Hunter-thingy that we have leaks smoke out of various orifices that it shouldn't - and hence, maybe, fumes. |
