The Hoyme Air Exchanger (HAE)-HRV is a Heat Recovery Ventilator that distributes fresh/exhaust air to and from the ‘Whole House as a System’ by simply using the furnace fan – See page 11 (HAAS)

For maximum expected efficiency, the HAE-HRV is to be connected close to the furnace on both return and supply plenums with nothing in between except the appliance filter. If a 6″Ø Power Humidifier (PH) is mounted between the two plenums, the efficiency of the HAE can be maintained by adding a power open damper to the PH to open only during the humidifying cycle

The HAE operates continual, even during the defrosting cycle, making it ideal to vent bathrooms, kitchens & central vac systems through it – See page 16 for details.

½” Ø Plastic Drain Hose #9

The ½” Ø plastic hose #9 (supplied) is to be fastened to the drain spout and always kept lower than the bottom of the pan for draining water collected during the defrost cycle*
Provide a low spot in the hose to act as an air/water trap
Rigid copper tubing ½” Ø is often used for horizontal distances

* Ice forms in the HAE during cold weather but automatically defrosts during the heating cycle of the furnace.

A single Furnace Fan generates the movement of air in and out of the HAE to automatically Supply/exhaust air to the house where needed. Therefore, the main purpose of the Manual Air Balance Damper is not to balance the flow of air through the HAE but to control the amount of hot air that flows through HAE so as not to lose too much heat during the furnace firing cycle (de-icing cycle) and at the same time to allow enough hot air to heat the incoming air during the regular non-heating cycle.

Suggestion: Start by setting the Manual Air Balance Damper (#5 ) to be two-thirds open.

With the Furnace NOT FIRING but the Furnace FAN RUNNING for approximately five minutes, and any intermittent house exhaust fans turned off, adjust the Manual Air Balance Damper so that the following approximate temperatures can be obtained.

If outside temperature is 0°C, then air entering the return plenum should be 18 to 20°C while the air leaving the HAE should read approximately 6 to 10°C
If outside temperature is -30 to -35°C, then air entering the return plenum should read approximately 12 to16°C while the air leaving the HAE should read approx. 0°C to -6°C

These are typical installation readings.

With these settings in winter months, ice forms during the regular non-firing cycle and melts during the firing cycle. During the summer, the HAE works in reverse with the air conditioned air that is exhausted cools the incoming summer air

The ‘House As A System’ (HAAS)

Question: A single Furnace Fan moves air in and out of the HAE and ultimately to the whole house, but tests show there is more aircoming in through the HAE than is being exhausted? This appears to be an unbalanced system

Answer: If houses were perfectly sealed and free from any exhaust fans, air leakage included, then the amount of incoming air through the HAE and being circulated through the house would return in an equal amount to be exhausted through the HAE

The HAE would then appear to be a balanced system. One cubic foot of air in equals one cubic foot of air out. But all houses have some air leakage, plus air being exhausted by separate fans. This results in less air being returned to the HAE for exhausting. Since the HAE has less air being exhausted than there is air entering, the HAE itself does show an imbalance of air flow. But when we consider the ‘House as a System’ and factor in air that is lost through leakage and exhaust fans, it follows that using the HAE, generated by a single furnace fan, allows the ‘House as a System’ to adjust and to maintain a more natural balanced condition

The defrost cycle of the HAE is also automatic that occurs only during the heating cycle of the furnace. There is no ‘down time’ for defrosting which will then actually allow a continual flow exhausting of air even during extreme cold temperatures. This means that it is ideal for venting bathrooms, kitchens and central vacuum systems through the HAE
