Review of Dowling Sumo stove
another review
as per the last review, we have this stove linked to a dunsley neutralizer. you do not have to be a rocket scientist to understand how it all works, the only difficult /expensive part is the normally open valve. the heat exchanger is basically a metal box with tappings if you can weld properly and understand how it works you could make your own. the weakness of the standard system is that it requires power to the circulation pumps to distribute heat, if power is lost the solution is to drain off domestic hot water, connect generator or install battery back up. The stove itself is a beast ! 220kg of beast! built to last.\n the only down sides are that the simplicity of design meeans that control of the heat out- put is down to the flue damper. in practise this is not a problem.\n we installed ours with a back up gas boiler, that we have never used . our gas bill is £5-8 quarter (the gas hob) the back up back up immersion heater has not been connected.\n\n
Stove expert replied: This stove user may not have a heat leak device in their installation. A heat leak device gives you a way of getting rid of excess heat in the case of a power cut or pump failure. Often you have a dedicated heat leak radiator, or you may have a coil in the boiler which is flushed through with mains cold water in the event of overheating (although this option is not available for this particular stove). Always get a boiler stove system designed and installed by an expert.
