THE OPEN SYSTEM

The open system uses one heat source, your domestic water heater, to provide both floor heating and domestic hot water. The two systems are basically tied together. The same water that ends up in your hot shower or dishwasher, for example, has passed through the floor first. This is a very efficient system because one heat source is doing all ON-DEMAND WATER HEATERS The Elite is another on-demand unit used for radiant heating applications. At up to 98% efficiency it is an extraordinary heat source, but the Primary/Secondary plumbing configuration recommended by Heat Transfer Products is somewhat more complicated than the Takagi..

THE CLOSED SYSTEM

Introduction This approach utilizes a dedicated heat source for the radiant floor. The fluid in a closed system is re-circulated around and around in a completely closed loop. There is no connection whatsoever to the domestic water supply. The main advantage to this system lies in the fact that, being closed, anti-freeze instead of

CONNECTING ADAPTORS AND COUPLINGS Adaptors. 7/8″ PEX Adaptor. Adaptors are the brass fittings used to connect PEX tubing to ¾” copper pipe. Since the adaptor is designed to sweat onto a stub of pipe, it can be used in conjunction with any fitting your installation demandsa copper tee, an elbow, or a coupling. To use an adaptor, first prep the fitting for soldering by TANK TYPE ~ GAS WATER HEATERS The Polaris is a “tank-type” water heater. It heats water at 96% efficiency, slightly better than the Takagi on-demand unit. But because the Polaris stores 50 gallons of hot water, it suffers from “stand-by heat loss” and that fact lowers its overall efficiency. The upfront cost of a Polaris is also high due to its stainless steel

tank.

FILLING THE CLOSED SYSTEM Air trapped within a closed radiant system is the most common cause of inefficient system performance. Fortunately, it's an easy problem to solve and won't become an issue at all if care is taken during the initial filling process.

THE CLOSED SYSTEM

Introduction This approach utilizes a dedicated heat source for the radiant floor. The fluid in a closed system is re-circulated around and around in a completely closed loop. There is no connection whatsoever to the domestic water supply. The main advantage to this system lies in the fact that, being closed, anti-freeze instead of

water

TANK TYPE ~ GAS WATER HEATERS The Polaris is a “tank-type” water heater. It heats water at 96% efficiency, slightly better than the Takagi on-demand unit. But because the Polaris stores 50 gallons of hot water, it suffers from “stand-by heat loss” and that fact lowers its overall efficiency. The upfront cost of a Polaris is also high due to its stainless steel

tank.

ELECTRIC, GEOTHERMAL, AND WOOD BOILERS RHEEM. Electric on-demand heaters can also be used for OPEN systems, providing both floor heat and domestic hot water.. Heat source efficiency is calculated by taking the heating unit’s BTU input, multiply that number by it’s efficiency,This equals the unit’s BTU output.Example: 100,000 BTU unit with a 98% efficiency has an output

of 98,000 BTUs.

PRIMARY/SECONDARY PLUMBING Primary/Secondary plumbing has been used for years in commercial and residential heating and cooling applications. In a radiant heating application, a properly sized pump on the Primary Loop triggers the on-demand heater whenever any zone calls for heat. This creates a circulating loop of hot water between the heater and a pair of closely

spaced

SLAB MANIFOLD

A copper manifold used to distribute heated fluid to a concrete slab. Slab manifolds come in many configurations, the simplest being the “1-loop” manifold. This is simply a supply connection to a single loop of tubing and its return. A “6-loop” manifold is generally the largest. Bigger than “6-loop”, and the manifold becomes

unwieldy.

HEATING WATER WITH SOLAR ENERGY Introduction Solar water heaters are commonly used as heat sources for radiant floor systems in regions where an abundant solar resource is available. Normally, a large solar heated storage tank (with electric, gas, or oil backup) supplies hot water to the radiant system and most often provides for domestic needs as well. Solar heaters interface

THE OPEN SYSTEM

The open system uses one heat source, your domestic water heater, to provide both floor heating and domestic hot water. The two systems are basically tied together. The same water that ends up in your hot shower or dishwasher, for example, has passed through the floor first.
