8 Energy Desi.qn Update January 1989


### For more information The results of this survey were presented at the last annual meeting of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), and were published in the ASHRAE Transactions, Volume 93, Part 1, paper number NY87- 09-3, available from ASHRAE, 1791 Tullie Circle, N.E., Atlanta, GA 30329; (404)636-8400.


# PRODUCTS 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 Hotsurface 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-byto backdrafting woes andholes 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. 8 anergy Design Opclate Januazy 1 989

### 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. For more information, contact MorFlo Industries, 18450 South Miles Road, Cleveland, OH 44128-4296; (216)663-7300.



## Hydronic Furnace from SnyderGeneral· SnyderGeneral Corporation has become the first major heating equipment company to market an air handler with coil intended for use with a conventional domestic water heater. Commonly referred to as "hydronic furnaces," the new SnyderGeneral 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.
