What Plain&Warm covers
and why

Plain&Warm is an independent editorial reference focused on ecological heating technologies for residential buildings in Poland. The content here covers heat pumps, hydronic underfloor systems, and building thermal insulation — three interconnected areas that together determine how much energy a home consumes for heating.

The site does not sell equipment, take affiliate commissions, or represent any manufacturer. Articles are written from publicly available technical data, regulatory documents, and research published by organisations including the International Energy Agency and the Polish National Energy Conservation Agency.

What you will find here

Three core topic areas structure the content:

• Heat pumps — how different heat pump types (air-to-water, ground-source, exhaust-air) perform under Polish climate conditions, with attention to real-world COP figures rather than laboratory benchmarks.
• Underfloor heating — installation sequences, screed types, pipe spacing, thermostat configuration, and compatibility with low-temperature heat sources.
• Thermal insulation — Polish and EU regulatory requirements (WT 2021), insulation material comparison, retrofitting considerations for older construction stock.

Editorial approach

Texts aim to be descriptive rather than promotional. Where comparisons appear, they draw on published data rather than manufacturer claims. Figures are cited where possible. No topic is treated as settled — energy technology shifts quickly, and older guidance becomes inaccurate.
