Before submitting a new icon request, please confirm the following:

• [X] I have searched all issues to make sure there isn't a request for this icon.
• [X] I have searched the current library to make sure the icon doesn't already exist.
• [X] I understand that brand icons are no longer being added and I can use SimpleIcons for my brand icon needs.
• [X] I only intend to request a single icon (or a few near-identical ones) in this issue.

What would you use this icon for?

There are various types of electric water heaters (geysers). The mdi library currently only includes a boiler, which may not be familiar to users that do use this type of system. This icon is useful in home automation and similar systems., as well as on schematics that show home layouts.

Give us an example of what this icon might look like.

We might want to adjust our current water-boiler icons to follow the pattern of the new meter-electric and meter-gas.
