Vloerverwaring instaleren in een huis met een kruipruimte.

[hector333]

Hello everyone,

I recently bought a house and will be moving in this March. I'm excited about making some upgrades and would love to get your advice on a couple of things.

House Details:

Energy Label: B
Floor Material: Concrete
Ground Floor: Has a crawl space
Plans:

Install Floor Heating: I'm considering different options like hydronic or electric radiant floor heating.
Install a Heat Pump: I'm looking into hybrid heat pumps for their efficiency.
Questions:

Floor Heating: Given that my ground floor has a crawl space and the floor is concrete, which type of floor heating would be most efficient and cost-effective?
Heat Pump: Are there any specific brands or models of hybrid heat pumps that you would recommend? What should I consider when choosing one?
Installation Tips: Any tips or things to watch out for during the installation process of both the floor heating and the heat pump?
Energy Efficiency: How can I maximize the energy efficiency of these systems given my house's energy label?

1. Hydronic. Stay away from electric floor heating.
2. Stay away from hybrid pumps as well. Hybrid is fear. If you can heat your house with floor heating you can do it with an all electric heat pump.
3. Make sure your floor is well insulated. Rc needs to be 3.5 or more.
4. I don't think i understand that last question.

The energy efficiency of your heating system is not really related to the energy label.

For an efficient system you should follow the following guidelines:

1. Size your heat pump based on the based on the heat loss of your house. For an existing house one can use the current energy usage. Search for 'koevlaas formule' on this forum (yearly heating energy divided by the appropriate full-time hours equivalent for your climate). Eg. 7000 kWh/1650h = 4.24 kW, which would suggest a heat pump of around 5kW nominal power.
2. Enable enough flow through your heating system. Usually 25 mm inner pipe diameter for your main pipes and 20 mm for the branches should be fine. Unless your house is a castle.
3. No zone regulation. Use weather compensation to regulate the flow temperature and hydronic balancing to regulate the flow to the rooms in your house. This will keep your flow temperature nice and low, and comfort level high.
4. Pumpless manifolds
5. No parallel buffer. In your case you will probably not need any buffer at all since you will have underfloor heating and ample water volume.
