ᐅ Combination of air-source heat pump and hydronic fireplace

Hi,

does anyone have this type of heating system in their home? Is it efficient? And how high are the costs? Is it possible to effectively combine an air source heat pump with a hydronic fireplace? What is the energy consumption? For example, a 100m² (1,076 sq ft) house for a family of four.

Too high. It’s not cost-effective. One heating system is sufficient. A fireplace is nice for coziness.
What are people always trying to save on when it’s only 600 € per year?!

BeHaElja, that’s a good question! Many people don’t really realize how high or actually how low the potential savings can be.

A fireplace with a water circulation system is not worthwhile in our climate zone and is a nightmare in terms of regulation. The investment far exceeds the potential savings.

The question is more whether the air heat pump is worth it. €15,000, with a 20-year lifespan, amounts to €750 per year. On top of that, there are maintenance and repair costs plus the basic electricity meter fee.

There are already building concepts where an air-to-water heat pump fits well—either to meet KFW standards or because the connection costs for gas are too high. Likewise, there are certainly people who simply prefer not to rely on gas for personal reasons.
I’m also not quite sure what you’re trying to demonstrate with your calculation... Gas plus solar probably costs about the same in investment, while a ground-source heat pump with deep drilling is even significantly more expensive.

P.S.: By the way, you can also run the heating on household electricity—then you save the fixed basic fee ;-)
