Tankless vs 2 water heaters

[Courtney Murphy]

Hello,

We purchased our first STR and the water heater is not adequate for the amount of people who will be staying in the house all at once. Also it is at the end of its life expectancy. It is a 5 bedroom 2 level house built in 1881. Should we go tankless or get 2 water heaters? We have tankless in our vacation home and it takes FOREVER to heat up unless we increase the heat and then possibly risk someone burning themselves.

Thank you!
