Outside Air Intake

England's Stove Works recommends professional installation of our hearth products.

Outside air intake is mandatory for all England's stove works freestanding pellet units to overcome the effects of negative pressure inside of the structure it is being installed in.  Newer houses are especially prone to this due to better building technology,  but all homes no matter how drafty they seem are effected in this way.

Since the early 1970's homebuilders have built houses in such a way as to make them more economical to heat and cool with electricity . This is done by making the house more airtight than was practiced in the past, this diminishes loss of heat through drafts and leaks in the home's structure, also, a lot of older homes have been renovated to gain efficiency as well. This tightly built construction can cause problems with combustion devices such as woodstoves and pellet stoves. more so with pellet units as a higher quantity of airflow is required for the unit to burn its fuel effectively. running a pellet stove using air pulled from inside the structure can lower the air pressure in the home in relation to the air pressure outside the structure, this is known as "negative pressure"

Negative pressure buildup inside a home reduces the unit's ability to receive the proper volume of air needed to effectively burn the fuel and drastically reduces the performance of the unit. The size of the structure does not matter in relation to negative pressure. Outside intake air defeats the buildup of negative pressure as the airflow comes from directly outside and is ejected back outside.
