In the private sector, power surges are not uncommon. Their high value can damage the electronics of the gas boiler, and low indicators help turn off the equipment and stop the heating. The rating of voltage stabilizers for a gas boiler, based on the characteristics of devices and user reviews, will help you choose a model that ensures uninterrupted operation of heating equipment.

The best wall voltage stabilizers for a gas boiler

Wall type voltage stabilizers are available with relay and electronic stabilization method. It is rarely possible to find a mechanical design, due to the increased dimensions of the internal parts, poorly suitable for a compact case with placement on the wall.

Such equipment is capable of ensuring the subsequent operation of the gas boiler with an input voltage of 140-270 V, but each specific model has its own indicator, which is important to consider when choosing. At the output, the stabilizers are able to constantly maintain 202-238 V. Their stabilization rate directly depends on the type of stabilizer and varies from 20 to 100 V / s.

The best floor voltage stabilizers for a gas boiler

Floor placement expands the possibilities for manufacturers to equip stabilizers, because there is no need for a compact case or low weight. Often in this category you can find very powerful models up to 2000 watts, but they are also quite compact at 500-600 watts.

Floor stabilizers can be installed under the table, on the table, or on a special shelf. Often they are placed in a niche or bedside table. This eliminates the need for owners to drill walls and lay wires with cable channels.The efficiency of such models varies from 85 to 97%. Interaction with the input voltage range can be from 140 to 270 V.
