Ensuring your heat pump is the right size for your home is just as important as choosing the right style.
Correct sizing is crucial in ensuring you receive optimal comfort levels for your home. Selecting a heat pump which is too small for the area you are trying to heat will result i increased noise, poor performance and higher power consumption as the unit works to achieve heating levels beyond its capability. Installing a heatr pump which is too large will create draughts and uneven heat output. Factors such as the age of the home, adequate insulation, the amount of glass windows and the climate of the area you live in must also be considered before installation takes place, as these have direct bearing on the performance required. Below is a guide to help you determine the approximate heating requirement of your room.
