ᐅ Which heating system? Where to start? With the manufacturer?

Hello everyone,

We are currently trying to gather information about heating systems but are a bit stuck. We plan to install an air-to-water heat pump for a KF55 house with 200m² (2150 sq ft) of living space and a volume of just over 900m³ (31,800 cu ft) across 2.5 floors. According to KFW, calculations are based on 275m² (2960 sq ft) of living space due to our high ceilings. I’m still getting answers on the required capacity and whether it should be a split system, but when it comes to deciding on the specific heating brand or model... we have no clue.

When we talk to installers, each one swears by the brand they install. Whether the equipment is actually good or if they just earn the highest margin on it, I can’t tell. Online, I often find answers saying that heating and controlled mechanical ventilation depend on the specific requirements, but surely the differences can’t be that big...

I compare it to cars. There are premium manufacturers like BMW, Mercedes, Audi, etc. Then there are luxury cars such as Lamborghini, Ferrari, Bentley, and very affordable brands like Dacia. And then you have brands focused on value for money, like Skoda and Seat. Skoda (VW) and Seat (Audi) might not have the newest gadgets but are close in quality to premium classes, while being significantly cheaper.

Is there a similar classification for heating and controlled mechanical ventilation systems? Or I strongly assume there is, but how can I categorize the manufacturers? Viessmann, Nibe, Vaillant, Buderus... these are companies I know but can’t really place. When reading, I come across names I’ve never heard before, but that doesn’t mean they are bad. For example, Weishaupt?

We are more looking for something like a BMW or a Seat, depending on price. Can you help us here? Is there maybe a list or are we missing something?

Of course, installation also matters, because even the best heating system won’t help us if it’s poorly installed. Or are manufacturer differences negligible so that we should focus more on the installer and just choose whatever brand they recommend?

Cheers

The required capacity is determined based on the heat load calculation. Regarding Weishaupt: it is a startup, and they still need to prove themselves in the market. Just kidding – it seems you’re not very familiar with the heating industry...
