Environmental heat for an apartment block
New build apartment house
Low-cost and ecological heating
The project involves building a new apartment block near Lake Chiemsee in Bavaria. The developer will be using a split heat pump for the heating system. Read on to find out the reasons for their decision.
The planned building is not intended for personal use. Instead, the developer wishes to sell it on soon after completion. Its location in one of the most popular residential areas and holiday destinations in Bavaria is ideal for this purpose.
On the other hand, potential buyers will expect high-end fittings and cutting-edge technology. Environmental considerations also play a role. The developer will have to meet these demands.
The cost of investing in an apartment building will be recouped over time by rental revenue. After this payback period, it will yield a profit. This is not the case for properties built for sale. The investor must obtain sales proceeds that are high enough to cover their investment and make a profit. In other words, they must keep the cost of construction as low as possible.
Yet, to achieve an acceptable selling price, the building must come up to an appropriately high standard for the region in question. This applies not only to the materials used for flooring, windows etc. but also to a heating and ventilation system with a long service life.
Reasons for the chosen system
The builder opts for a modern split heat pump. He forgoes solar heating in favour of a photovoltaic system.
Heating systems that use environmental heat are technologically mature, efficient and durable. They are not only suitable for privately owned homes, they can also reliably supply apartment blocks with heat and hot water. Natural gas and heating oil will progressively increase in price due to the CO2 tax on fossil fuels enacted in 2021. The operator can render themselves immune from these rising prices by using a new split heat pump heating system.
The heating system obtains the majority of the power it requires from the environment free of charge. No fossil energy sources of any kind are consumed. As a result, the heat pump does not release any CO2 or particulate matter into the atmosphere. If a photovoltaic system is used to generate the electricity needed for the heat pump, the heating system becomes nearly climate-neutral.
The heating system in question is a split system. It is divided into an outdoor and an indoor appliance, which takes up less installation space indoors. Also, the noisier appliance section is located outside so it will not disturb any of the new apartment owners. Furthermore, the appliance has a night mode that is even quieter.
New buildings are characterised by being well-insulated and having almost air-tight building envelopes, amongst other things. However, the upshot is that there is no natural exchange of air between the building’s interior and the exterior environment. This makes a controlled home ventilation system indispensable.
The ventilation system brings fresh air into the building and extracts the used air. It also removes excessive moisture and prevents the risk of mould formation in the building. A heat exchanger removes the heat contained in the extract air and uses it to warm the supply air. In this way, barely any heat is lost from the building due to ventilation.

Powerhouse for the apartment block heating system
The new heating system is very well equipped to provide heating and DHW heating in the new apartment block – and all without using fossil fuels. The ventilation system also keeps the indoor environment healthy and pleasant and prevents mould from forming in the building.
All of this increases the value of the building considerably. So the developer has a good chance of making an agreeable profit from the planned sale.
