There's nothing that responds to a little care any better than the LP-Gas regulator. But if it is overlooked, trouble can result. Remember these points:

Hydronic (liquid) systems, popular and cost-effective systems for heating-dominated climates, have been in extensive use in Europe for decades.

First Stage Propane Regulators LV4403TRSeries 200x200 are installed at the propane tank and connected directly to the service valve with a pigtail. If a first stage propane regulator is used, a second stage propane regulator must be installed downstream. In other words, a first stage propane regulator can't be installed independently in an LP Gas system. There must be a second stage propane regulator installed as well. The first stage propane regulator will compensate for differing tank pressures and will deliver into the gas line at a pressure of 10 pounds or less. The purpose of a first stage propane regulator is to deliver propane at an ample pressure to a downstream second stage propane regulator. That's its only job... to ensure that the second stage propane regulator is supplied with propane at a pressure that it needs to do its job. The REGO variations of first stage propane regulators are numerous and while they are all designed to work with propane tank pressures, the outlet pressures differ by model. First and second stage propane regulators must be properly matched so that the overall gas system is safe and functional. Propane companies work with REGO regulators every day and are able to determine what size and type of first stage propane regulator is needed for the requirements of the installation.

Because air cannot hold large amounts of heat, radiant air floors are not cost-effective in residential applications and are seldom installed.

Hydronicradiant heat

Electric radiant floors are usually only cost-effective if your electric utility company offers time-of-use rates. Time-of-use rates allow you to “charge” the concrete floor with heat during off-peak hours (approximately 9 p.m. to 6 a.m.). If the floor's thermal mass is large enough, the heat stored in it will keep the house comfortable for eight to ten hours without any further electrical input. This practice saves a considerable number of energy dollars compared to heating at peak electric rates during the day.

Tubing for a hydronic system may be installed in a conventional concrete slab or in a lightweight, gypsum-cement slab. It can also be stapled to the undersides of subflooring as shown in the image below:

Second Stage Propane Regulators are not used for decreasing tank pressure and, therefore, must be installed downstream of a first stage propane regulator for safe and proper operation. Any regulator seen installed next to a building, most likely are a second stage propane regulator. Second stage propane regulators work with propane at a pressure supplied by the first stage propane regulator (inlet pressure) and further decrease that to a pressure that can be used by appliances (outlet pressure). Most outlet pressures of second stage propane regulators are measured in inches water column, such as 11" water column. This is the standard propane pressure delivered to household appliances so that they can safely and properly operate. Second stage propane regulators are only designed to operate in combination with first stage propane regulators. One cannot work without the other.

Radiantheating system In ceiling

A new generation of in-floor hydronic heating that employs corrosion-proof, hot-water tubing has enjoyed widespread popularity in recent years. With this type of system, heat is evenly distributed and floors are warm under foot. A variety of heating equipment may heat water: natural gas or propane water heater or boiler, electric boiler, wood boiler, heat pump, solar collector, or even geothermal energy.

Integral Twin Stage Propane Regulators are more commonly used and are more sensible for most installations with a small BTU load inside... BUT in a situation where there is an extreme distance between the tank and house or appliance, a two stage propane regulator system is often the best option. The reason for this has to do with several things including pipe size, total service line distance and appliance BTU demand. A long run (50 ft. and over) from the propane tank to a house with a total load being over 1,000,000 BTU would most likely benefit from a two stage system because an integral twin stage will not supply the propane required that the appliances demand.

Hydronic radiant floor systems pump heated water from a boiler through tubing laid in a pattern underneath the floor. The temperature in each room is controlled by regulating the flow of hot water through each tubing loop via a system of zoning valves or pumps and thermostats.

Wet installations are the oldest form of modern radiant floor systems. In a wet installation, the tubing is embedded in the concrete foundation slab, or in a lightweight concrete slab on top of a subfloor, or over a previously poured slab.

Although ceramic tile is the most common floor covering for radiant floor heating, almost any floor covering can be used. However, some perform better than others. Common floor coverings like vinyl and linoleum sheet goods, carpeting, wood, or bare concrete are often specified.
