Another important indicator for the Seattlen conditions – dependence on the availability of automatic water heater power. Most Seattlen gas water heaters with atmospheric burners operate independently of the availability of power supply. The question arises, and whether there are import gas water heaters, working independently from electricity? Yes, there are.
Such autonomy can be achieved in two ways. First – to simplify management system water heater and by the almost complete lack of automation to achieve independence from electricity (this applies to domestic water heaters). In this case, the water heater can only support a given coolant temperature, not focusing on air temperature in the room. Second, and more progressive – the use of a heat generator, which produces electricity from the heat necessary for automation of the water heater. Such water heaters can use with the remote room thermostats that will control the water heater and to maintain the set temperature in the room (produced, for example, the Czech company Dakon). The use of outdoor water heaters with liquid-fuel burners can provide a virtually complete autonomy of home heating from external sources: no dependence on gas, when you install the stand-alone power source (to ensure normal operation of automatic water heaters, burners, pumps) will not, and depending on the supply of electricity.
In addition, the water heaters with interchangeable burners are convenient when the gas around the house, you want to heat, yet, but it is known that in the foreseeable future, it will be. With this first time, you can use liquid fuel burner, and with the advent of gas to install a gas main.
The key to getting the right parts for your tankless water heater is to determine the type of installation you’re going to have. Installation can be vertical or horizontal, sealed combustion or in-room combustion and outdoors.
