Ode to a radiator

My radiator has got the blues
When it's not on, (and it should be)
It is clammy and cold
And feels old
Like the rubber carrot
That hides limply
Behind the marrow
In the fridge
Hoping no-one will find it

My radiator has got the blues
And what's more
The boiler is in on the plot
Coz it doesn't feel too hot
And it's very off, and on
And off and on

My radiator has got the blues
And the bad news is
There's no hot water either!
