Air Exchanger For Radiant Floor Heat

The intention of the heated floor is primary to ensure comfort and happy feet the air source heat pump is far more efficient and so we rely primarily on that to heat the air of the home.

Air exchanger for radiant floor heat.

The important point to understand is that most of the time heat exchangers are not essential in a radiant system. In the radiant floor vs. Basically fresh air enters the home from an opening to the outside and then passes through the exchanger that is circled by indoor air. Radiant heating is the more efficient system so operating costs will be lower and the material costs are very affordable.

The staple up radiant floor installation method is very popular because as long as you can see the joists from below you can install radiant heat. The exchanger transfers the heat from the warmer air to the cooler air. A heat pump ventilator does what an hrv erv does but with a heat pump instead of a passive heat exchanger. In fact it works so well that it has almost entirely replaced the thin suspended slab applications see below.

Conversely and cleverly in summer if the heat isn t needed in the house the heat is diverted to an air water heat exchanger for heating the hot water tank instead. Solar collectors almost always use antifreeze so a heat exchanger is necessary in this application also. The radiant floor is heated with an electric boiler it is a separate system than the heat pump. While air exchanger designs do vary by manufacturer they all operate on the same primary principle.

In the winter the air that is supplied to the house can be warmer than the air extracted from the house and in the summer the supply air can be cooler than house air and cooler than ambient air. Air heated by those solar panels in winter when the sun s angle is lower will be fed into the floor heating radiant system which will reduce the energy demand on the heater coil. Is it necessary to install a room to room air exchange system ducts to each room blower in the attic in a home heated solely with radiant in floor heat. Forced air heating debate radiant floor always wins because it provides a quiet even heat and eliminates the allergy problems often associated with heating ducts.

In addition the installation cost is very cost effective usually priced between 3 75 to 5. Radiant heat vs forced air cost. This method works well for new construction and retrofits. As you can see this allows the boiler to heat a tank of potable water which in turn can provide domestic hot water and floor heating in an open or closed configuration.

A common concern is how do the systems compare when considering radiant heat vs forced air cost.
