Is it better to connect two electric boilers in series or in parallel?

First, the radiators are installed in parallel:

1. The advantage of installing radiators in parallel is that multiple temperature control valves and multiple pipes can control the temperature of each group of radiators separately, which will not cause uneven indoor temperature. It is easy to control multiple rooms one by one.

2. If the radiator has water leakage, corrosion and other faults, the temperature control valve of the recombined radiator can be closed separately for maintenance and replacement, and other radiators are not affected by it.

3. If no one lives in other rooms, you can also close the temperature control valve of the radiator in this room, which is very beneficial to the heating mode of household metering.

Second, the radiator is installed in series:

1. Radiators are installed in series. In terms of advantages, the series installation saves materials, only one pipe is needed, the installation cost is relatively low, and space is saved. However, the shortcomings are also obvious. Because of the way of series installation, the temperature control of each group of radiators has problems and cannot be well controlled. The temperature in the room is unbalanced and the temperature difference is obvious, so every room needs special care. If you want to save money and space.
