Ventilation Which fan is right for my bathroom?

You don’t replace a bathroom fan every year, so it pays to choose the right one first time. With good extraction, your bathroom dries quickly after a shower, the grout and ceiling stay free of mould, and you’ll hardly notice the noise of the fan, if at all. Choose a fan that is too weak or doesn’t suit your ducting, and the moisture will linger and the fan won’t do much good. In this blog you’ll find out, among other things, why ventilation is so important in the bathroom, which type of fan suits your situation, how to calculate the extraction rate you need, which controls are useful, where to install the fan safely and what to look out for when fitting it.

Installation & maintenance What is an enthalpy exchanger?

In this blog, you'll read how the vapour-permeable membrane in an enthalpy exchanger works and how much moisture is recovered in practice. We work this out for you with an example in the Mollier diagram, a chart that engineers use to map the properties of humid air. You'll then find out what an enthalpy exchanger does for you in winter and summer, and how an enthalpy exchanger differs from a cross-flow heat exchanger and a humidifier. Finally, we list a number of MVHR units with an enthalpy exchanger.

Ventilation Adiabatic cooling: what is it and how does it work?

In this blog, we explain exactly what adiabatic cooling is and how an adiabatic cooler works together with your MVHR unit. Halfway through this article, a worked example shows you how much cooler the fresh air coming into your home is. You will also find out which type of MVHR unit adiabatic cooling works with, where to install the cooler and how the cooler itself decides when cooling is useful and cost-effective.

Air Quality The top 5 best CO2 monitors on Ventilationland.co.uk

Wanneer je voor een langere tijd in een ruimte bent, is het belangrijk om te weten of de luchtkwaliteit goed is. Wanneer dit niet het geval is loop je risico om last te krijgen van diverse gezondheidsklachten. Zeker wanneer je met meerdere mensen in huis of op kantoor bent, kunnen de CO2 waarden snel oplopen. Nu is niet alleen de blootstelling aan een hoog CO2 niveau erg schadelijk, ook corona kan makkelijker overgedragen worden in een ruimte met een hoge ppm waarde. Een koolstofdioxide meter is dus onmisbaar geworden. Dit apparaat geeft aan wanneer het CO2 niveau te hoog is in een ruimte, en daarmee wanneer het tijd is om te ventileren.

Installation & maintenance Installation MVHR ventilation system and mounting tips

Installing an MVHR unit is very achievable. However, you do need to know what to look out for. An MVHR system (mechanical ventilation with heat recovery) ensures a healthy indoor climate by continuously supplying fresh air and extracting stale air, while recovering the heat from the extracted air. That's efficient, but it does require the MVHR unit installation to be done correctly. Whether you want to install an MVHR system yourself as a DIY enthusiast, or simply want to understand how connecting an MVHR unit works: in this blog we take you through everything you need to know, step by step. From the right mounting position and electrical connection to duct selection, sound insulation and commissioning your MVHR installation.

Ventilation What is smart ventilation?

Smart devices are becoming increasingly common in homes. We control our lighting, thermostat and security systems easily via an app or with voice commands. Ventilation, however, often receives less attention, even though fresh air is essential for a healthy indoor climate. Fortunately, there are now ventilation products that can be fully integrated into your smart home. Smart ventilation means that the system operates automatically based on air quality, humidity, occupancy or schedules. It reduces manual effort, improves living comfort and makes ventilation much more efficient. In this blog, we explain what smart ventilation is, what you need for it and which products from the Ventilationland range are already suitable for app or sensor control.

Air Quality Our tips and tricks for ventilating in summer

The temperature outside is rising quickly: summer is here! Warm weather is often lovely, and we spend a lot of time outdoors. What is less pleasant is the heat slowly entering your home. The result? An uncomfortable and sometimes even unhealthy indoor climate. Many people keep windows and doors closed during the day or even switch off the mechanical ventilation in their home. That is not the right way to fight heat. By ventilating at the right times and consciously managing the indoor climate, you can keep the air in your home fresher, healthier and more pleasant. In this blog, we tell you more about this.
