{"product_id":"stuart-504-boiler-stock-code-3177","title":"Stuart 504 boiler","description":"\u003cp align=\"left\"\u003eA well looked after specimen of a Stuart 504 water tube boiler,  largest of the 500 range. Copper silver-soldered construction, 60psi working  pressure. The boiler was originally supplied with a primus type burner,  pressurised from a bicycle pump and running on paraffin. I've seen these paired  with other Stuart boilers, although never a 500 type before. Best bet by far is  to replace with a modern ceramic gas burner, which brings a welcome degree of  control to steam production, whilst also burning very quietly.\u003c\/p\u003e  \u003cp align=\"left\"\u003eFurther details about all the 500 series boilers are filed away  on my \u003ca href=\"..\/..\/Stuart\/500%20series%20boilers.htm\" target=\"_blank\"\u003eStuart  page\u003c\/a\u003e.\u003c\/p\u003e  \u003cp align=\"center\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54020172579157,"sku":"3177","price":195.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/3177-1.webp?v=1779911674","url":"https:\/\/stationroadsteam.com\/products\/stuart-504-boiler-stock-code-3177","provider":"Station Road Steam","version":"1.0","type":"link"}
