Renovation of a detached house in 49124 Georgsmarienhütte

The detached house (built in 1962) underwent extensive renovation in 2015. The ground floor was fitted with underfloor heating using the IDEAL CLASSIC EPS 30 and the COMPACT FLOOR PRO 12 , with tiles and parquet flooring. The same system was installed on the ceiling and sloping roof walls of the upper floor, as well as additional wall heating in the bathroom. Triple-glazed windows were installed. Insulation was limited to the top floor ceiling and the basement ceiling. Instead of further insulation measures, the focus was on upgrading the building services, including a heat pump, a ventilation system with heat recovery, and a photovoltaic system.

Easy adjustment of the heating elements thanks to predetermined breaking points

**Underfloor Heating Installation** The advanced IDEAL Classic EPS 30 water-based underfloor heating system was integrated on the ground floor. Thanks to the dry installation, the building structure was not burdened with additional moisture, which also resulted in a shorter construction time. — Underfloor heating installation:The advanced IDEAL Classic EPS 30 water-based underfloor heating system was integrated on the ground floor.

Uniform spacing allows for optimal use of the area for effective underfloor heating

Fast and efficient installation thanks to a clear laying grid.

The pipe is laid in the prefabricated channels

The slabs can be walked on after a few hours.

**Installation of the heat-conducting layer** The COMPACT FLOOR PRO 12 cement fiberboard was installed as a floating dry screed. The 12 mm thin boards have high thermal conductivity and were subsequently covered with parquet and tiles. — Installation of the heat-conducting layer: The COMPACT FLOOR PRO 12 cement fiberboard was installed as a floating dry screed.

The heat-conducting layer, which is only 12 mm thick, ensures rapid heating and cooling of the parquet and tile floor

**Installation of ceiling heating/cooling** In combination with a heat pump, the system provides comfortable warmth in winter and pleasant coolness in summer, thus increasing living comfort. — Ceiling heating/cooling installation: In combination with a heat pump, the system provides comfortable warmth in winter and pleasant coolness in summer, thus increasing living comfort.

Easy installation, even on sloping roofs

Stable construction using intermediate battens in drywall construction

Straight-line routing of the system pipe through the pipe guides of the heating elements.

Easy integration of, for example, ceiling spotlights

The Omega pipe channels hold the pipe to the ceiling

Comfortable warmth in winter - pleasant coolness in summer

Comparison of electricity consumption for full-room heating

SYSTEM IDEAL WITH HEAT PUMP AS FULL ROOM HEATING

The building was equipped with the IDEAL system for radiant heating and cooling on the floor, walls, and ceiling, as well as a heat pump that also provides hot water. As part of the renovation, a 7.8 kWp photovoltaic system was installed, along with a ventilation system with heat recovery. To create a cozy atmosphere, a fireplace was installed, integrated into the heating system via a water jacket.

Up to 29% of energy consumption can be covered by PV electricity.

Analysis of energy consumption

The total electricity consumption of the detached house amounts to 10,210 kWh. This figure includes the household electricity consumption of the family of five, as well as the electricity consumption for the heat pump (heating, cooling, hot water) and the ventilation system. With an average household electricity consumption of approximately 5,000 Wh*, about 5,210 kWh are attributable to the heat pump and ventilation system. Approximately 29% of this demand was covered by the photovoltaic system, reducing grid consumption to 3,700 kWh. The annual wood consumption for the fireplace is 4 cubic meters.

TOTAL ENERGY COSTS

Before the renovation, annual oil consumption was approximately 5,000 liters, resulting in costs of €4,970. Thanks to the modernization and the installation of the IDEAL system with a heat pump, electricity costs now amount to approximately €1,667.20 per year.
The additional use of renewable energy generated by photovoltaics reduces electricity costs by about 29%, resulting in energy costs of €1,184 per year.
