How To Install Hydronic Systems Under Existing Floor

This is primarily used when the floor joists are exposed say in rooms over an unfinished basement or crawlspace.

How to install hydronic systems under existing floor.

The first is in the floor itself the other under the subfloor between the joists. Hydronic systems circulate heated water through pex tubing that winds under the floor. Below are common hydronic installation methods. A pex radiant floor heating system can be the most comfortable efficient and often may be installed for less than other heat delivery hydronic systems.

A hydronic floor is no less complicated than a zoned baseboard heat system. According to the this old house website the retrofit costs about 700 for a bathroom including the tile. The feet are always warmer than the head. Radiant floor heat stratifies the heat from the feet to the head.

There are two distinct ways to install a radiant floor heating system. Whether you are building a new custom home from the ground up or undergoing an extensive remodel hydronic systems can be installed in almost any situation. Hydronic systems can also be installed beneath floor joists. This is what feels naturally comfortable to our bodies.

In most situations hydronic water based systems are the most efficient. A good compromise is to install the hydronic system right in a concrete slab and install the wood on the concrete. But that said even a wood floor will warm up and heat you and the room quite well. Radiant heat systems are easily hidden under a tile floor.

In this case the tubing is run between and through the joists and anchored to the subfloor. If you can access your floor joists from below you can easily install energy efficient radiant heat under your existing floors. It uses a boiler heated by gas oil or electricity and requires valves and manifolds to distribute the water as well as sophisticated thermostats to control the heat. There are many different ways to install a residential hydronic heating system in your home.

The last system is the floor joist installation. Another option for radiant floor heating that is energy efficient are systems that circulate hot water through small tubes under the floor. Install pex tubing before pouring a concrete slab for the home or install it when using plywood as a subfloor. When you are installing wood floors over top of concrete the double layer two layers of 1 2 ply floating plywood method will be the best method.
