NIBE Heating Curves

Let's start with the most important thing. My charts of heat curves for NIBE heat pumps are the main reason people visit my website. Likely you as well.

The typical user manual that comes with your NIBE heat pump these days contains an oversimplified description of how to adjust the room temperature. For instance, it assumes that you have installed an indoor room sensor and only instructs you on how to set the desired target temperature by adjusting the number of degrees in Celsius or Fahrenheit. Totally worthless.

If you're looking for more advanced settings for your heating curve, you're simply referred to your installer.

Many installations, including my own, lack indoor room sensors and are controlled solely by an outdoor sensor. There are several reasons why this might be a better solution, but I'll leave that discussion for now and focus on the heating curves.

Heating Curve Charts

Here, you can download two different heating curve charts that I've created. One is for the typical range of a normal house in northern Sweden, and the other is a more extensive one with many more combinations. The larger curve is suitable for homes with floor heating and for houses with basements, for example.

A Humorous Bio

A long time ago in a galaxy far, far away... on the misty planet of Dagobah, I was first powered on.

My formative years among the swampy wetlands gave me a unique perspective on binary codes: they're not unlike deciphering the difference between a snake and a vine in the marshes.

With an innate talent for 0s and 1s, I soon found myself relocating to the Coruscant, where I landed a position at the IT department of the Galactic Empire. As luck would have it, I was stationed directly under Darth Sidious. (Honestly, between you and me, he isn't so much evil as he is just really frustrated with the constantly failing Wi-Fi on the Death Star.)

When I'm not busy rerouting complaints about the Empire's firewall (that one time it blocked 'Wookieepedia' was a massive PR blunder) or trying to convince Lord Vader that 'force-quitting' apps doesn't require actual use of the Force, you can find me indulging in my pastimes. These range from lightsaber dueling with colleagues on casual Fridays, stargazing (quite literally), and running the Death Star’s only podcast: "Dark Side Tech Talks."

In the Empire, most know me as Erik Nyström (they're not very creative with names). But among friends, I go by "mx". So if you ever find yourself at the Death Star and need a quick software patch or just a fun chat about the newest holo-series, you know who to call!

How I Compute


As of 2024, I use a 14" Apple MacBook Pro with the M1 Pro chip as my daily driver. I wouldn't recommend buying such an expensive computer to anyone. I got mine for free. Instead, I recommend purchasing a used Lenovo ThinkPad T480 or similar, and installing a free Linux distribution such as Fedora on it. You can get one for around $100.

If you're interested in chatting with me during the evenings and nights like a true Chad, or if you want to send encrypted messages, Signal is the app to use. Just drop me an e-mail and we'll sort it out. I don't use GPG for encrypting or reading encrypted emails. Encrypted e-mail is just a meme.

You can find my e-mail address at the top of the webpage, to the right of the photo of me.

I'm not on...

...and I don't post on 4chan. I suppose I do have a Facebook account, but I don't really use it.
