Installation Tit-bits Of Heat Recovery Ventilator

High level of moisture is a chronic problem in many houses. Too much moisture in the room air can lead to an array of problems such as growth of mold and mildew in the house; the framework of the house can be affected due to humidity; and the residents can contract an array of diseases. The best way to deal with such situations is get an HRV fitted in the house. A HRV will bring in fresh air from outside and purge the stale air from the rooms. Besides this, it captures heat in outbound air/inbound air and reuses that energy to condition the inbound fresh air. As a result it makes the indoor air warmer in winter and reduces pressure on the furnace to heat the room. Here we will take a look at some installation tips of an HRV-

• The heat recovery ventilator comes in different shapes and designs. Some can be mounted at your window or wall opening just like an air conditioner. These units are meant to ventilate individual rooms. You will often find them in bathrooms, painting studios, laundry rooms, darkrooms etc. There are HRVs that designed to ventilate the whole house. These need ducts to circulate the fresh air to different rooms.

• The ducted ventilators are mostly installed in new house where new duct work is laid to suit it. However certain models of ventilators also work well in retrofit situations. Particularly if the older homes have duct work then these can be improvised to circulate fresh air from the HRV. Houses with unfinished basements can also have a ducted HRV installed. The basements can be used to lay a ductwork.

• Cost of installing a heat recovery ventilator will depend on variety of factor such as ducted /room-sized models, the length of duct needed etc. A room-sized unit meant for ventilating individual rooms would cost from $350 to $450. Ducted models will cost a bit more. They range between $400 to about $1,500. As for installing the ducts, you have to take quotes from various contractors and decide on one.

• The energy requirement of HRV depends on capacities of each model. The manufacturers of HRVs make products in different sizes with varying CFMs. You have to choose a size for your house depending on the CFM of the model and the number of occupants in the house. By the standards of ASHARE, a good ventilator should minimally expel 15 CFM per occupant.

• The efficiency of a HRV depends of length of the ducts. Short and straight ducts will make the system more efficient.
