Change water temp on old Richardson boiler

Twntwo Member Posts: 1
Hi, I'm renting a house with a very old Richardson boiler (probably 1910s or 1920s). As far as I can tell, it works fine, but the water gets scaldingly hot. I want to lower the maximum water temperature so my young daughter doesn't burn herself. I can't find an obvious dial to lower the temp and I'm clueless about boilers, heaters, etc. I'm adding a picture of the boiler and the on/off switch that seems to have some kind of temperature gauge. Any help would be greatly appreciated!

    Scalding Water

    Hey, from what i see in those pictures i BELIEVE its a steam boiler ,i believe i see valves for a gauge glass and a pigtail to a p-trol????correct me if wrong........and it also looks like you have an external tank for your domestic hot water, thats the pic with the temp adj.(AQUASTAT), if it was my house install a mixing valve.it'll prevent scalding water thanks PAUL S
