We are planning to install a "hydro-air" or warm air system in a new home. We want to use a boiler to heat the air and the domestic water.

1. Anyone had experience with the Lifebreath clean air furnace? (It's an air handler and HRV combined:

2. How about the System 2000 by Energy Kinetics ( Any experience with this boiler? (We use oil, natural gas is not available)

3. Forced air systems ane not commonly installed in a new home here, although HRV's are becoming common due to "tight" home construction and extreme moistur problems in this rainy climate. Is it necessary to have an air system designed by an engineer?

4. Will there be a cold air return in EVERY room? Does this return belong on a wall near the cieling? midway? near the floor? or on the ceiling or floor? (assuming the best of construction circumstances?

Thank you

Wish I could help, but too many questions and they are not spacific as to how the equipment is being incorporated into the house. Sounds like you are doing your homework and that is half the battle.
Your local contractor should be able to help you with youe selection and all of your questions. I have not heard of this particular brand of heating equipment, but It may be the most used in your area and will probably do the job....

NO!! I need help. NO ONE uses this system here. In addition the preferred and by far most common heating system is hydronic (either baseboard water or, if you can afford it, in-floor of some sort). Consequently contractors constantly urge us NOT to use an air system at all (the local term is "scorched" air) and most do not install them, usually just commercially or in retrofit situations.

So, since tight houses here have a moisture problem, some sort of ventilation is added--passive ie: vents in walls or closets or most expensive an HRV--a controlled air to air exchanger with built in heat recovery. This requires installation of ductwork in ADDITION to the hydronic system already installed.

Since I want a dry house, and I like forced air, and wish to heat domestic water with a boiler (electricity is expensive for this)....What I've found is that one can install an air handler which heats the air with water from the boiler using an arrangement of tubes and a blower to the ducting system.

It is this "hydro-air" system that I am interested in. I have found a device that combined the air to air exchange and the air handler in one unit. Some have homes that can use their domestic water to flow into this unit--therefore no boiler would be necessary. This is the Lifebreath clean air furnace. It's only about two years old so it's not widely in use, yet.

Even if you are not familiar with the hydro-air systems, I'm still interested in answers to questions 3 and 4?? These should be she same as a standard forced air system.
