One type of radiant heating system in use today utilizes the domestic hot water tank as a heat source. This means your domestic hot water does double duty, heating the house as well as coming out of the tap. Here are a few of the radiant heat supplies you will need.
The first place to start is a hot water tank. It is a good idea to have a larger capacity if possible, to avoid excessive run times. If you are looking at a renovation or upgrade, there is a good chance you will already have one in use. Otherwise, consider an energy efficient model.
Cool fluid or water from the radiant heat system is pumped through the Flat Plate Heat Exchanger. At the same time, hot water from the tank circulates through and loses heat, warming up the radiant heating system.
After the heating fluid leaves the Flat Plate Heat Exchanger, it flows through the loop of PEX tubing or radiators. A circulating pump pushes it along and it loses heat on the way. Heat rises through the floor to warm the entire building. This endless loop continues as long as the diy radiant heat system is active.
One way check valves are some of the other radiant heat supplies you will find it necessary to pick up. These will prevent fluid from travelling the wrong way.
Expansion tanks are necessary to keep a leak from developing or parts from being wrecked. As the circulating fluid is heated and cooled, it will grow and shrink enough to strech or break your tubing without one of these.
Manifolds are needed to split the water into multiple lines or loops. A supply manifold and a return manifold are common components of the diy radiant heat supplies.
If you are in need of more fittings or clamps as your diy radiant heat work progresses, you will be able to find them at the plumbing section of the closest home improvement center. Radiant heat supplies are one item that is usually on the shelves.
A diy radiant heat system that utilizes the existing hot water tank isn’t really that complicated. With a little research into radiant heating supplies, you will be ready to begin working on it in no time.
