Ecofire Nightrods are manufactured by us here in the Midlands. Nightrods are specifically manufactured from bark from our sawmilling process in order to achieve ultimate longevity.
Nightrods can be used either as a low energy, long burn briquette on those days of in between temperature in order to take off the chill while not throwing out too much heat or as a way of retaining heat in your stove/appliance overnight.
If all air intakes are shut down and the Nightrods are placed on the hot embers of a pre-existing fire then there is a chance they may make it through the night and the stove may still be warm in the morning.
Those cold winter mornings may not be so cold when using Nightrods.
