In many households, especially in older residential or commercial buildings, the existing plumbing system is not designed for central hot water systems. If you still don't want to do without hot water, a boiler with a plug is the ideal solution. So-called under-sink boilers are particularly popular: they are easy to install, save space, and do not require complex electrical installation.
In addition, the European Union has increasingly promoted energy saving and emission reduction in recent years – mini-boilers are gaining importance as they have low heat loss and only heat the required amount of water.
The most important consuming countries in Europe are:
| Country | Land | Features |
|---|---|---|
| DE | Germany | High demands on energy standards, mature market for small and under-sink boilers. （ThermoMate Mini Tank Electric Water Heater Energy Efficiency Class A） |
| FR | France | Old buildings, focus on energy renovation, stable sales figures for mini-chauffe-eau. |
| IT | Italy | Decentralized hot water supply is widespread, users prefer point-of-use hot water solutions. |
| ES | Spain | Lower demand for hot water in summer, mini-tank ideal as an extra in winter. |
| PL | Poland & Eastern Europe | Many new buildings and renovations, mini-tanks as a cost-effective option. |
