## Questions

### Will one tankless unit cover my home?

One unit covers two showers running at once in most homes. Larger homes, or hard water without a softener, may need two. We size it from your fixtures, not a brochure.

### Does my gas line need upgrading?

Often, because tankless units burn more gas while they run. We check the line on the site visit; any new run is quoted separately.

### Why descale every year?

Scale builds up in the heat exchanger and cuts the flow. Most makers require a yearly service to keep the warranty.

### Is it worth it over a tank?

It costs more to install and less to run, and it lasts about twice as long. With a family and a long stay in the home, it usually pays back.
