Heat Pumps in Utah New Construction: What Builders Should Know

Oct 5

2 min read

More Utah builders and buyers are asking for heat pumps. They can work well in our climate when the design starts from the load calculation and the details are planned before rough-in.

Start with the load, not the brochure

Manual J uses local winter and summer design conditions to find the real heating and cooling load.
Manual S matches equipment to that load, including how much capacity the unit keeps at cold outdoor temperatures.
Manual D sizes the ducts for the airflow the heat pump needs.

Plan the backup heat

On cold mornings a heat pump may need help. Decide early whether backup comes from electric heat strips or a gas furnace in a dual-fuel system, because it changes the electrical service, the gas piping and the controls.

Outdoor unit placement

Raised on a pad or stand so snow and ice do not block the coil.
Clear of roof drip lines, dryer vents and bedroom windows.
A drainage path for defrost water so it does not freeze on walkways or driveways.
Line set routes and wall penetrations planned before siding.

Electrical coordination

Heat pumps, heat strips and air handlers add electrical load. Share the equipment schedule with the electrician and the designer early so the panel and service size are right the first time.

The payoff

A heat pump designed this way runs efficiently, keeps rooms comfortable and avoids warranty calls after closing.
