Re: Whole house frozen -- how bad will it be?
SherryH by removing as much as you can, radiators, toilets, etc while still frozen and opening the lines at the lowest point, basement preferably, then put a heater in the basement and try thawing from the bottom up, you can minimize water damage. However you will probably have to replace the pluming including the hot water heating lines. Depending on the configuration of the house you may be able to run PEX up through the walls with a minimum amount of holes in the plaster or drywall. Most drain lines should be OK except traps. The hot water heat lines could be the big problem and expensive with a great deal of tearout. The freezing should have little or no effect on the electrical.
