Statistically, we spend up to 80% of our time indoors. Can you imagine that the air quality in your house is better than the fresh outdoors? If the answer is no, bring controlled ventilation to your home or business with ClimateLink. We have partnered with Stiebel Eltron, a company which specialises in green energy relating to heat recovery ventilation, heating and cooling. Investing in Stiebel Eltron heat recovery ventilation systems is a must because ventilation is necessary as the building constructed are getting more airtight. The Benefits of choosing heat recovery ventilation include:
The growing air-tightness of our homes, whether new or recently renovated, underscores the importance of consistent air circulation. This circulation is essential not only for maintaining a healthy indoor environment but also for preventing issues like mould growth and structural damage. Relying solely on opening windows for ventilation proves impractical – achieving an energy-efficient and hygienic air exchange would require frequent opening of windows throughout the day, often with the heating system turned off, which is hardly feasible.
In today's modern homes, energy efficiency is a top priority, and houses are designed to be incredibly airtight, minimising energy loss. This is especially true for low-energy houses, where an airtight building envelope is a key feature aimed at preventing heat from escaping. While this is a great energy-saving strategy, it comes with a crucial challenge – the lack of natural airflow.
Even in older homes, ventilation can be a pressing issue. With the addition of thermal insulation measures, the once permeable spots like gaps in windows and doors are sealed off, reducing the inflow of fresh outdoor air. This creates a dilemma, balancing effective thermal insulation with the need for a constant supply of fresh air.

Centralised heat recovery ventilation involves the cross current heat exchanger, providing the home with a comfortable atmosphere. This filters the fresh air from outside to inside, and exhausting stale air from the house through a machine called the cross current heat exchanger, where it exchanges energy so it doesn’t lose heat. There is a remote control available and is highly energy efficient.

The decentralised heat recovery system is a small device which is effective if you are renovating. It filters in hygienic air from outside and eliminates excess moisture. The installation is fairly simple as it connects through the outside wall to the inside wall.
During the heating season, the HRV captures heat from the outgoing air and uses it to preheat the incoming fresh air. During the cooling season, an HRV can reverse this heat-exchange process, removing some of the heat from the incoming air and transferring it to the outgoing air. It does not have an active heating or cooling system like an air conditioning system.
However, windows don’t have to be opened for fresh air, which lets the indoor warmth escape. With this eliminated, the use of traditional heating or air conditioning can be minimised. HRV systems do not actively change temperatures but maintain the indoor temperature while introducing fresh, filtered air from outside, even on cold winter days. The machine provides continuous fresh, filtered air to your home while keeping up to 90% of the indoor heat inside. It is as efficient as opening a window but much less expensive.
We install Stiebel Eltron HRV systems. Our HRV system is equipped with two coarse G4 filters to protect your home from dust, mould, and pollen particles. Filters need to be maintained every 3-6 months, depending on the levels of pollution outside. A visual check after three months is recommended to assess how frequently you want to replace your filters. When they are visibly dirty or clogged, either wash them under cold water or order replacements at STIEBEL Store. Additionally, we offer ClimateLink to come out and replace the filters for you.
There are stages 0-4 which can be selected on the wall controller.
Stage 0
Humidity Protection (Standby)
Stage 1-3
Variable Speed Control
Stage 4
Full Speed (Maximum Air Removal)
It has been a long journey since I engaged ClimateLink for a HRV system. During the period, I searched a few different products, Dalibor provided professional suggestions and customised plans. Finally I settled down with a Stiebel system. I am happy with the whole process and the final installation. Highly recommend ClimateLink!
