  • Pool heating with ribbed pipe systems – Build your own solar heating for the pool

    Black pipes on a rooftop pool heating system in the foreground, with a backyard swimming pool, lawn, stone wall, blue shed, and covered seating area in the background on a sunny day. www.commaik.de

    Pool heating, solar absorber, Ripp pipe system and the efficient use of solar energy – in this article I document the complete conversion of my old EPDM pool heating system into a modern Dolphi-Ripp solar heating system. After more than ten years of practical experience with EPDM mats, I will show you why the change was necessary, which system is convincing today and how the new solar-based pool heating is proving itself in everyday life. Step by step, I describe the planning, installation and initial results – including technical details, comparisons and practical tips for installing a solar absorber on the roof.

  • ECOVACS GOAT A1600 RTK: The innovative robotic lawnmower without boundary wire in the test

    A robot mower without boundary wire, with a grey and white casing, moves from a brick patio onto a green lawn bordered by stones and gravel. www.commaik.de

    A robotic lawnmower without boundary wires can revolutionize lawn care – no more laying and repairing wires, just precise navigation with RTK technology. The ECOVACS GOAT A1600 RTK promises exactly that. After more than 10 years with the Gardena Sileno+, which was regularly slowed down by broken cables, we needed an alternative. In this test, I show how the GOAT A1600 RTK performs in practice: from installation and mapping to mowing quality and safety. Is the cordless robotic lawnmower really convincing? Here is the answer.

  • Installing a lawn sprinkler: Step-by-step instructions for watering your garden

    A person holds a trencher, creating trenches in a grassy yard for irrigation. Several orange buckets filled with soil are placed around the dug areas, with a brick path on the right and a stone building in the background. www.commaik.de

    Installing lawn sprinklers and setting up efficient lawn irrigation – that’s exactly what this article is about. I show how I planned my garden irrigation system, laid the PE pipes and equipped the system with automatic irrigation. I explain step by step how to excavate the trenches, connect the sprinklers with Hunter Swing-Joints and test for leaks. In the end, the irrigation runs reliably and saves time when watering.

  • Laying the water pipe in the garden: tips for connecting the water supply to the garden irrigation system

    Open trench in a paved area with exposed cables, pipes, and a water pipe in the garden, surrounded by loose soil, bricks, and paving stones—signs of ongoing underground utility or lawn irrigation work. www.commaik.de

    Laying a water pipe in the garden is a crucial step for efficient garden irrigation and reliable lawn watering. In this project, the pipeline had to be routed under an existing cobblestone path. The paving stones were removed, a trench dug and the pipes laid together with empty conduits for control and power cables. In addition to the right choice of material, frost resistance also plays an important role. The entire process – from planning and leak testing to restoring the sidewalk – is described in detail in this article.
