HVAC, Plumbing, and Electrical

All of this equipment will be painted to match
the siding and trim, just like the gas supply
line on the left side of the meter.

Todd also installed a supply line for our
underground sprinkling system.

On the right side is the new dedicated manifold
for the toilets.

He replaced the main cold water trunk line
between the water meter and the utility
room to make sure that we would could fill
our air tub quickly. And, he improved the
design of the system that feeds water to
toilets, to prevent sweating. Don Bohs, his
boss, recommended making those changes.

Todd, from Shoreline Plumbing, made some
adjustments in our bathrooms and improved
several aspects of our plumbing system design.

We plan to have the exterior panels painted at a
body shop so that it will blend in with the house.

Our Heat Pump/Air Conditioner is larger than we
expected, but we are OK with it because its size is
a product of its efficiency (15 SEER, 8.7 HSPF).
That's Bill Adams on the right, helping with the
installation.

...and the dining room. Other rooms on the main
level with recessed lights include the master bath,
mud room, guest bath, stairway, and hallway.

...and the main bedroom...

We installed recessed lighting in the living room...

Between the window wells is a pad we built
for the air-source heat pump.

Another view showing the duct that sends
warm air to the rooms in the basement.

The furnace is close to being complete, but the
air source heat pump (with A/C) outside has not
yet been installed.

This is our "Energy Recovery Ventilator" (ERV).
It transfers heat and moisture from stale inside
air being vented out to fresh outside air being
drawn in. The manifold on the left accepts ducts
from the bathrooms and from a central location
near the stairwell (barely visible below).

This is a view of a bulkhead in the downstairs
hallway that hides heating and ventilation ducts,
and plumbing for the kitchen area. At the far end
you can see the access to the crawl space below
the kitchen.

On the opposite side of the same room you can see
the ordered chaos of utilities in the mechanical room.

Want to see some pipes? These pipes and ducts
serve the bath and laundry room on the main
level, as well as the kitchen.

MJM in Shelby is handling the basic plumbing for us.
The system has PEX runs from the manifold (shown above) to
each fixture. Each line has a shutoff valve and a drainage cap.
Two 40 gal water heaters (one gas, one electric) are connected
in series, with the gas heater doing the work. The electric
heater increases the system's capacity for filling tubs, taking
concurrent showers, etc. We have a sump and a grinder pump.
[Update: Several plumbing system adjustments and improvements
are being implemented by Shoreline Plumbing and Heating, also in
Shelby (Don Bohs, Todd & Matt).]

Frank and Chris are the HVAC crew from
Adams Heating and Cooling. The system they are
assembling for us includes a natural gas forced
air furnace, air source heat pump (A/C and heat
down to about 30 degrees outside) with a central
humidifier and an energy recovery ventilator. The
system is controlled by an Arzel HeatPumPro.
