Heat Recovery Systems Can Reduce Heat Loss by 75%

With energy prices at record levels, people around the country are finding that the cost of heating their home is higher than ever.  Coupled with increasing concerns about our impact on the environment and the threat of climate change, it has never been more important to look at ways in which we can reduce our consumption of electricity and gas by making our homes more efficient.

There are simple steps that we can take to reduce our energy use such as changing to LED bulbs and choosing more energy efficient appliances but heating our homes during the frosty winter months while also keeping air fresh indoors can be difficult.

The problem with energy efficient modern homes

Modern buildings are designed to be as energy efficient as possible.  Flush fitting windows and doors that prevent draughts, thick insulation in walls and ceilings, and double glazing are all great at preventing heat loss, but they also make the building more airtight. 

The air in our homes needs to circulate and escape.  Without good air flow, moisture from cooking and bathing can build up and cause condensation problems that ultimately lead to damp and mould.  Similarly, the chemicals from cleaning products along with other pollutants will increase which can cause allergic reactions.  During the winter months, when respiratory diseases such as flu and more recently, Covid, are at a higher-level, poor-quality ventilation can increase the risk of transmission between people.

In many homes, the only way to effectively improve the ventilation and air flow is simply to open a window, but during the colder months of the year, this is simply not practical, because it means that the warmth in the home is quickly lost, which leads to unwanted increases in heating bills.

Mechanical Ventilation with Heat Recovery is the Answer

Mechanical Ventilation with Heat Recovery (MVHR) is a centralised or single room ventilation system which passes air through a heat exchanger before extracting if from the building.  The energy captured from the extracted air is used to heat the incoming air from outdoors so that less energy is wasted overall.

EnviroVent offer a range of different MVHR systems including the HeatSava which is an intelligent single room solution that can replace a standard extractor fan.  HeatSava is fitted through the wall in a bathroom or kitchen, and couples a low wattage fan system, with a 75% efficient heat exchanger to run at a low cost while minimising heat loss from your home.  Compared with a traditional extractor fan, HeatSava is much more energy efficient, and thanks to an intelligent moisture sensor, it will automatically adjust the amount of power used to prevent condensation.
