How to choose an instantaneous water heater
What should I look for when buying the best instantaneous water heater?
Power
In flow heaters, a powerful copper heating element is mainly used, due to which water is able to quickly heat up, flowing through an insulated circuit. This allows you to quickly receive large (and even huge) volumes of hot water. On average – from 4 to 15 l / min. True, these types are more suitable for apartments or cottages. If you need to provide hot water to a large room with several points of water intake, then you can already think about purchasing a storage boiler.
Management
Instantaneous water heaters can have both mechanical and electronic control. The second is the most convenient, as it allows you to set the exact temperature that the device must maintain. A nice addition here is the presence of a display.
Dimensions
Compactness is an undoubted advantage of the vast majority of instantaneous water heaters. Due to their relatively small dimensions, these devices can be placed both on the wall and in special cabinets, which cannot but please in conditions of limited space.
Economy
Given the high power of such devices, we should expect an increased consumption of electricity. If the average heater is capable of providing hot water to a small apartment, then a device operating at several points of water intake must have significant power. Of course, this will negatively affect energy bills.
Additional functions
As for electric models, the presence of an electronic display will be a pleasant plus, thanks to which you can control the settings. Gas heaters, on the other hand, can please with electric ignition from batteries – it allows the device not to depend on electricity.
Checklist for buying the best electric heater
1. If you choose a water heater for a large room with several points of water intake, it is better to focus on storage boilers
2. Instantaneous water heaters are compact in size and can fit into almost any interior.
3. When buying, it is important to clarify where the water supply comes from. Models with a top supply are often inconvenient to connect to the water supply.
