You can set the spa at a low resting temperature and it will still heat up quickly. They function well but they are expensive to install. You will need a gas line connection to supply gas to the unit, of course. The unit has to sit in the open air for exhaust purposes.

The installation is a breeze too. Plus, the maintenance and repair costs are low. They might take more hours to heat the water, especially if the temperature outside is cold.
