Are you planning to install a heat pump in a house with an old heating system? How can you protect the heat pump from the damaging effects of an open system? Read about how heat pumps are practically separated from old installations using plate heat exchangers.

How is a condensing boiler in an sealed system connected to an open installation using a plate heat exchanger? How is the heat exchanger selected for this application, and what needs to be considered? We discuss all technical and practical aspects.

In today's blog post, we take a closer look at the thermostatic valve for a hot water tank. Find out if you really know what it's used for, how to choose the right model, and why it's worth investing in one! Enjoy reading.

The specifics of using plate heat exchangers (or others) with groundwater, river water, rainwater, deep well water, or brine are entirely different from using them with municipal water. Most manufacturers exclude warranty coverage for heat exchanger tightness if they operate with untreated water. Why?

Solid fuel boilers most often require operation in an open system, which somewhat limits our options for connecting them, for example, to underfloor heating. However, there are ways to address this – check how the connection between sealed and open systems works.

Read this if your heat pump has started generating higher costs and consuming more electricity than usual. If there’s an issue with your return on investment and it was supposed to be cheaper, check what the possible reasons could be.
