Master Therm: The Red Ferrari in the Basement

A ground-to-water heat pump heats a family home in a foothill region in the northern part of the Czech Republic.

While air-to-water heat pumps have become extremely popular in recent years across many countries — including the Czech Republic — thanks to their lower installation costs, ground-to-water systems maintain one key advantage: a highly stable heat source that delivers superior efficiency, especially in areas with harsher climatic conditions.

Modern Heating for a Historic Building

A great example of a long-running ground-to-water installation can be found in a modest yet carefully maintained family house in the village of Varnéřovice. The building, dating back to the late 19th century, blends seamlessly into the surrounding architecture, respects its heritage, and at the same time conceals the best of modern heating technology. The house is thoroughly insulated — the façade, roof and windows — and behind the historic window frames, an additional set of triple-glazed windows is installed.

In the garage, a plug-in hybrid is parked, and the roof carries a photovoltaic system. Beneath the open part of the garden, free of tall trees, lies the ground collector that serves as the heat source for the AquaMaster 37 Inverter heat pump. The entire setup is elegantly completed by the fact that both the heat pump and the buffer tanks are fitted into a small cellar under the house, leaving the basement space fully usable.

The Second Master Therm Heat Pump in the House

The current AquaMaster 37 Inverter model is already the second Master Therm heat pump “parked” in this home. The original AquaMaster 37 was still operational, but the homeowner decided to replace it proactively with a newer model. His only request was that the new heat pump should also be red — because, as he says, he wanted to keep his “Ferrari”.

He has not yet calculated exact savings compared to the older model, but he particularly appreciates the ability to connect the system to the internet, the convenient mobile app control, and the pGDx controller — all features the previous 2009 model did not offer.

“The newly installed heat pump is much easier to operate compared to the old one, it’s quieter, and with internet connectivity you’re much closer to your service provider. Thanks to Master Therm and the installation by PremioKlima, we now have a red Ferrari in the basement,” says homeowner Ladislav Kubizňák.
