Can I install an HRV myself?
A: The short answer is yes. A heat recovery ventilator can work in a home with no ducts. If you can install the stale air intake on one level and the fresh air output on another level, then a ductless HRV installation works perfectly. I know because that’s the situation I have in my own house.
How is an HRV installed?
The two standard ways to distribute fresh air throughout the home are through the ductwork installed for the HRV (a direct-ducted system) or through the ductwork of a forced-air furnace system. An HRV can also be installed to work with a forced-air furnace system, as shown in Figure 3.
How much does it cost to install a HRV system?
Cost of an HRV or ERV System. A whole-home HRV or ERV system can range anywhere from $1000 to $4,500+ with installation. The cost of installation may be lower if the unit is being installed at the same time as the furnace, as opposed to separately at a later time.
Where should HRV be installed?
POINTS TO CONSIDER WHEN LOCATING THE HRV/ERV UNIT The unit must be installed where it is easily accessible for maintenance and filter changes. The unit should be relatively close to an exterior wall to minimize the length of insulated duct to the exterior vent hoods.
What setting should my HRV be on in winter?
Whilst your ventilation level is a personal preference and makes the HRV adaptable to any home, it is suggested that you lower the ventilation level to 1 during the summer months and increase it during winter to above 3. Having it above 3 in winter will ensure any condensation is minimised.
What should my HRV be set at in summer?
As a general rule of thumb, you should set your system’s dehumidistat to 25 percent to 50 percent depending on the temperature to keep condensation at bay. For instance, 50 percent is the maximum relative humidity you should have if the outdoor temperature is between -11 degrees Celsius to 18 degrees Celsius.
Should you use HRV in summer?
The answer depends on your home’s air conditioning system, your ERV wall control, the outdoor temperature and, most importantly, the outdoor relative humidity. As a rule of thumb, if you are more comfortable outside than inside your house, you should run your air exchanger in the summer.
Is an HRV system worth it?
Are HRV’s worth it? Although there are many answers to that question, perhaps the best answer is: Yes, it can improve your quality of life.
How often should you run HRV?
Sizing the HRV for the home as a rule of thumb is ⅓ air changes per hour. For the most part, this can be done without running your HRV 24hrs a day. That’s why the newer style of digital controllers are getting installed.
Should you leave HRV on all the time?
HRVs and ERVs do require energy to run, but this energy is offset by the heat recovered from the exhaust air. To ensure that you home is well-ventilated and maintains good air quality, your HRV and ERV should run continuously.
Do you need an outdoor damper for fantech heat recovery ventilators?
Fantech heat recovery ventilators (HRV) that use a supply fan shutdown for frost preven- tion do not include an outdoor air motorized damper. If you are using a simplified installa- tion, i.e. connecting the HRV supply air duct to a furnace’s return air duct, the HRV must operate continuously.

How many CFM does HRV need for bathroom?
Bathroom: If the HRV is going to provide the required local exhaust ventilation for each bathroom with each a continuous 20 CFM (10 L/s), this ventilation rate can be considered as part of the whole-building ventilation rate. 5 Installation examples FULLY DEDICATED SYSTEM BEST FOR NEW CONSTRUCTION
