The term boiler originated from 'back boilers' used in old houses. If a woman is a 'boiler' then she keeps you warm at night so long as you give her a good poke every now and again!
She's definitely a boiler - wouldn't mind giving her a good poke!

A boiler refers to an unattractive older woman who is only good for the pot, as in having to cook an old chook in boiling water to make it tender and more eatable. The expression old chook also refers to a boiler and can be used in the same context.
There's not much to look at here just a couple of boilers.
