Hydronic radiant hot water floor heat

hydronic radiant hot water floor heat

Radiant floor heating has been used for centuries. The Romans channeled hot air under the floors of their villas. The Koreans channeled hot flue gases under their floors before venting them up the chimney. In the 1930s, architect Frank Lloyd Wright piped hot water through the floors of many of his buildings. Home builders’ surveys have shown that, if given a choice, most new home owners prefer radiant floor heat over other types of systems.

These surfaces surround a person with warmth. Efficient and economical Wirsbo Radiant Systems keep families like yours cozy and comfortable and often increase the resale value of your home.

Radiant floor systems can be wet or dry. Wet systems are 1/2 to 7/8 tubing embedded in a poured-concrete slab or in thin, lightweight gypsum floor poured over a wood sub-floor. This system works well with glue-down finish floors like stone or ceramic tiles, or when stamping and finishing the concrete. We use this method all the time when finishing our basements (we break the existing concrete slab, dig up the dirt for additional headroom, and then install the tubing after installing insulation boards).

More recently, dry systems have been developed that use mechanical fasteners to hold the tubing and a heat-transfer plate to distribute the warmth. There are two possible installation options for the dry system: One installation method fastens the tubing to the underside of the sub-floor (between the floor joists) in combination with aluminum heat-transfer plates, a system commonly referred to as staple up. The other, newer method uses manufactured panels and can be referred to as an above floor system. Above floor systems are installed above the sub floor and below the finished floor.

Because of its higher energy efficiency, an above floor dry system will be used for our project; Manufactured panels on top of the sub-floor have a quicker response time than any other systems because the tubing is closer to the surface.

Wood floor panels are necessary for this type of hydronic radiant heat. The following are the four main manufacturers we found:

This site is not very good at explaining and selling this product, nor can it give you any simple specifications, like the thickness.

Ok, after talking with the sales rep, the board thickness is 5/8, and the channels are for 3/8 PEX.

Viega Climate Panel System (PDF file) is a method of choice for radiant heat installation in wood frame construction. Fastest, cleanest, easiest way to install radiant heat over wood subfloors, existing concrete slabs or in the walls. The boards are only 1/2 thick, but the manufacturer web site is silent on the size of the channels, leaving you in the dark on what size PEX you can use; Is it 5/16, 3/8 or 1/2.

-The answer is 5/16.

Warmboard combines a high strength tongue and groove plywood structural APA rated sub-floor panel with a state of the art low mass high performance radiant heat floor panel. The same labor that would normally just install a structural sub-floor, simultaneously installs the panels that become part of your radiant heating system.

In a nutshell, this is sort of a two-in-one product 1-1/8 thick, combining your 5/8 or 3/4 typical sub-floor and your 1/2 channel panels with aluminum heat-transfer plates. Perfect application would be when building new. May be your best option if your typical (plywood or OSB) sub-floor is not yet installed. Seems to be the only one in the industry that accepts 1/2 PEX.

Non-structural Thermalboard is designed specifically for sub-floor applications. It is constructed of dense composite board covered with aluminum that spreads the heat evenly and quickly. Thermalboard heats rapidly and is easy to control with setback thermostats for maximum energy efficiency. 5/8 thick, can only receive 3/8 PEX, a bit small. Warmzone provides complete radiant heat packages .

Quik Trak is an ingenious and cost effective method of installing radiant floor heating in new construction, and also brings affordable radiant heating solutions to troublesome cold spots in existing homes. The patented system of wood panels (7 x 48 or 10 x 48) attached to aluminum heat transfer sheets can be installed over a plywood sub-floor, offering an alternative to joist heating and poured floor under-layment installations. A groove down the center of the panel holds the Wirsbo 5/16 hePEX™ plus tubing. Return Traks with a U groove complete tubing returns. The slim 1/2 panel profile adds minimal floor height, but can only receive 5/16 PEX, a bit small in our opinion.

Wirsbo is also a manufacturer of PEX tubing and can provide you with an entire radiant heat package solution .
