We have a 350 square foot addition which includes a bath. Is it practical to heat this with a hot water heater, either tankless or conventional? A This Old House show used 2 tankless hot water heaters. One heated the hot water for the addition, and the other provided space heating. How would this be done?

Katherine – A tankless heater is a tank with a separate copper coil inside. The tank water is piped to the heating system, and it also heats the water in the coil. The coil water is piped to the potable hot water in your faucets. These units are more efficient in Northern climates, because the tank (boiler) must be heated year round. Note that Bob Villa generally wears a sweater in summer, and a snowsuit in winter !
