Cover tiger loop in Winter?

[Gordon Rogers]

Hi all.
We have just had a new oil system installed including an external Tiger loop. I see that the 'new' Tiger loops are now a complete metal unit (as opposed to the previous plastic dome).
My question is - In the depths of UK Winter, may it be necessary for me to cover the Tiger loop to protect from freezing conditions? The oil lines obviously have some insulation around the copper pipe but the Tiger loop and associated compression joints have nothing.
Thanks in advance.

No. Look up freezing point of kerosene.

Place they freeze will be the filter and that's just because of the crap they collect which freezes.

Kerosene doesn’t freeze but rather waxes up and the temperature in which that happens is below -10°c I believe. You shouldn’t need to and when the burner is running the oil circulating through the loop is actually warmed a little.
