The Best(?) Integrated SpacelWater Heater for Low-Energy Houses

Move over Apollo. Mor-Flo Industries has just announced a new integrated potable water/space heating

appliance that has more features,

fewer drawbacks, and better price than

any of the competition, including the

popular Apollo Hydroheat. The new

Mor-Flo Integra is a one piece combined water and space heater with high

efficiency, completely sealed combustion, hot surface ignition, small

footprint, and low price. Unless unexpected operational or quality problems

arise in the field, this new appliance

should be a winner.

Mor-Flo first entered the integrated water heater/space heater market

with the introduction of its highefficiency Polaris water heater and

accompanying hydronic fan coil unit.

But the high price tag on the Polaris

eliminated that unit from all but

extremely high-end jobs. Mor-Flo

then began promoting its Nautilus

water heater as the supply for the

air handler, creating a package that

was attractive, but not distinctively

different from competing products.

With the introduction of the Integra,

Mor-Flo is now leading the market.

A Forced-draft Sealed Combustion Water

Heater

One of the Integra's unique features is its completely sealed forceddraft combustion system. A small

induction fan draws combustion air

from outdoors through a 2" PVC pipe

and exhausts combustion gases back out

through a sidewall vent. The unit is

completely decoupled from the indoor

air. The heater can be located up to

25 feet from an exterior wall.

Mor-F1o

Integra

Hot surface ignition

One way the Integra achieves its

high efficiency is by eliminating the

standing pilot light and replacing it

with a hot-surface ignition system.

In addition to energy savings, this

type of ignition eliminates much of

the headache and danger of relighting

the water heater after any type of

shutdown.

Good-by to backdrafting woes and holes in utility

room walls

Because it has completely sealed

combustion, the Integra should be

totally immune to backdrafting unless

the unit leaks. Furthermore, since

it draws combustion directly from outdoors, there will be no code requirement for an outdoor air vent into the

furnace room.

Betterthan the competition

This is not the only sealed combustion water heater on the market, but

it may be the best. Of the four

others, three (State, Rheem, Mor-Flo)

are passively vented and must be

located within a few feet of the exterior wall. The fourth is the new

Amtrol HP-41 (see EDU, July 1988),

which is power vented, but cannot be

installed more than 12 feet from an

exterior wall. The Amtrol unit is

also considerably more expensive than

the Integra.

Air Handler on Top of Water Heater

The fan-coil/air handler of the

Integra is mounted on top of the water

heater. This vertical configuration

and resultant small footprint should

make the Integra very attractive in

the small multi-family and apartment

markets.

The air handler comes with hydronic

heating coil and optional direct

expansion cooling coil.

Capacity

According to Gary Bosma at Mor-Flo,

the output from the water heater is

34,000 btu/hr and the heating coil is

designed for maximum heating load of

about 28,000 btu/hr. Two cooling coils

are available - 1-1/2 and 2 tons.

Efficiency

. According to Bosma, the space heat1ng AFUE (Annual Fuel Utilization

Efficiency), calculated using the new

DOE procedure for combined systems

is 85%. The Energy Factor (EF) of'

the water heater a~one is .72 (if not

used for space heating) .

Price and Availability

Bosma told EDU that the contractor's price for the Integra

(uninstalled) will be about $1,000.

Assuming that to be accurate, one

would be hard pressed to put together

a system with comparable features at

a better price.

. The I~tegra.is now going through

f1eld tr1als w1th six gas utilities

and should be on the market later

this year.

Commonly referred to as "hydronic

units, which will be marketed under

its Arcoaire and Comfortmaker brand

labels, are the same basic configuration as the Apollo Hydroheat and

First Aqua-Therm Aire. SnyderGeneral

started with its standard indoor

section for its split-system heat

pumps, replaced the electric resistance strip heater with a copper/

aluminum hydronic heating coil, and

added a circulator pump with necessary

controls. Two sizes are available -

TYPICAL UPFLOW INSTALLATION

TYPICAL HORIZONTAL INSTALLATION

Arcoaire hydronic furnace can be installed in

either upflow vertical or horizontal position.

Foamed Fiberglass Insulation

It's called Fiberiffic and if it

turns out to be as good as the claims

made by its owner - Ark-Seal Inc.,

Denver, Colorado - this new insulation

system has considerable promise.

Ark-Seal has always sold installation equipment for a system called ~Blown-in-Blanket" (BIB) (see EDU,

July 1988). With the BIB system,

loose-fill fiberglass insulation is

mixed with a small amount of latex adhesive as it is injected into stud

cavities. Thin nylon netting,

stapled on the stud faces, holds the

insulation in place while it dries.

In a properly done BIB job, the insulation dries into a monolithic

~batt" that completely fills the stud

cavities, surrounding pipes, wires,

and other obstacles.

Fiberiffic is an attempt to improve

on the BIB system by eliminating the

nylon netting. A special mixing nozzle

foams the adhesive as it mixes with

the insulation. According to Jesse

Aragon at Ark-Seal, the mixture has a

consistency between shaving cream and

dough. The glue binder is the same

latex material used in the BIB system.

It contains no formaldehyde.

Installation

The foamed Fiberiffic mixture will

not stick to vertical surfaces, but

it does dry quickly and, once dry,

will stay in place in a vertical stud

cavity without support.

To install the insulation, a

"trowel," the width of the stud cavity

and about one-foot high, is held

against the wall studs at the bottom.

The insulaton is injected behind the

trowel, filling the stud cavity. The

trowel is slowly moved up as insulation is continuously injected. The

adhesive dries quickly enough so that

the material stays in place as the
