Heat pumps: A growing trend in heating systems

According to a recent study, over 150 new users sign up to an app called Cool Calc each day.

Founder and chief executive Bill Fiore explains that the heat loss calculation is a key part of designing an efficient heating system.

A heat loss calculation is a figure, usually measured in watts, that defines how much heat a home loses during cold weather.

Installing a heat pump is a big decision that requires careful consideration of various factors, including the size and type of system, insulation levels, and the building's overall design.

Founder and chief executive Bill Fiore explains that the heat loss calculation is a figure, usually measured in watts, that defines how much heat a home loses during cold weather. This estimate is especially important to get right when installing a heat pump, which is sized fairly precisely, according to the projected heat loss.

Should that calculation be off, the heat pump will likely perform poorly. You could be left with an underpowered device that struggles to warm your property, for example. Given the costs involved, homeowners are often anxious to ensure installers avoid such mistakes.

Certain new technologies are not helping, adds Fiore.
