Choosing the most functional and inexpensive boiler for heating, you need to pay attention to the material of manufacture, strength, shape, volume, supply and other important nuances that will have weight in matters of heat transfer. Let's consider the most popular models and find out which of them are the most consistent with the principle "price = quality".
Evan Next 7 kW
Maximum thermal power 7 kW. Heats a room up to 70 square meters. It is placed mainly on the wall, which saves a significant part of the space. The mains voltage required for the operation of the boiler is single-phase and three-phase. The control is carried out mechanically, using buttons on the device itself.
The device is made of stainless steel. Manufacturers offer three power levels in this model, and the coolant temperature varies from 30 degrees Celsius to 85 maximum. You can connect an underfloor heating system. A very useful function "overheating protection" is built in, which will protect the device from high temperatures and their harmful effects.
The boiler is compact, dimensions 205 * 605 * 105 mm. Weighs about 8 kg. The service life is 10 years, and the warranty period is 2 years.
