With respect to eviction, a tenant can voluntarily leave; you cannot force them out. In other words the the typical eviction notice states if you leave on your own no legal action will be taken. You can ask the tenants to leave, I believe this was the message they were trying to convey. Here is a link to a brochure on the eviction process in WV
You have the right to shut off the water to fix it, but not just shut off the water because there is a leak which will not be repaired in a timely manner. No one wants wasted water. A repair for a water leak should be done within a day or 2 that is justifiable. Intentionally delaying the repair is called a constructive eviction, the failure to repair. If you called to have repairs made immediately upon discovering the leak then you do not have a problem with the water being off even if the repairs take a long time e.g. running an entire water line.
If the water company shuts off the water because you failed to have a repair made then you have a problem. It is your responsibility to make sure that water is available to the tenants. Without water a unit is referred to as uninhabitable. Short periods without water are OK lengthy period due to the landlord not taking action is unacceptable.
With respect to the electrical heat you can specify that space heaters are not allowed, and you can file for eviction if the tenants violate that rule. The issue is not that the tenants should be evicted it is how you went about it. You needed to obtain a court order to force them out. You cannot illegally force them out of the property and then claim as justification they violated the lease.
With respect to the electrical outlet that is the landlord's responsibility to fix in a timely manner. Again a reasonable repair time is expected in a couple days, not weeks. If one outlet is bad or is questionable that yo cannot shut off the main breaker. You should t shut off the breaker for that outlet.
At this point you are on the hook to immediately fix the water and electrical and restore utility service. If not you tenants can make file a costly law suit against you. Initiate the appropriate eviction process. You need to be concerned that you stick to violations of lease terms, and failure to pay rent. Other actions could subject you to "retaliation claims" for complaining abut a wrongful eviction.
