How to Replace a Radiant Heat Manifold

The use of a radiant heat manifold has important advantages for households located in cold climates and has gained considerable popularity around the world. The radiant heating system is well received because it is clean, efficient, quiet and reliable and is installed within the system of the house. Basically, it is an invisible heating system. Even though this kind of heating system can be installed on ceilings or walls, most households prefer installing it under the floor’s surface. The contractor or company can install the system within poured concrete subfloors. Other installation options include:

  • Within structural concrete slabs
  • With the base of subfloors
  • Inside the panels on top of these floors

How Radiant Systems Work

Radiant heating manifold systems use warm water to provide heat. The warm water circulates through a tubing system looped in an organized fashion. The looping tubes transmits the heat up to the floor and then towards any surface that comes in contact with the flooring system. Carpets, furniture and even tiles can warm up with this system. The transferred heat can help individuals feel warm and comfortable.

Replacing Radiant Heat Manifold

Radiant heat systems are very reliable; however, there will also come a time when they have to be replaced. Either the system is malfunctioning already or it has to be enhanced. Replacing a radiant heat system is possible. Nonetheless, the cost for such depends on the project. There are instances wherein replacing the radiant heat systems need expert service while there are also cases wherein people can simply replace their own system. In either case, it is important for users to plan their project before replacing or installing another radiant heat system.

Heat Load Requirements

Before replacing the radiant heat system, it is important to learn first about heat load requirements. This indicates the heating capacity of the heat source and is essential in radiant heat replacement. Heat load requirement is measured in BTUs per hour. The output of BTU per hour indicates up to what extent the system should be replaced or improved.

Tubing System

The most important aspect in replacing a radiant heat system is the tubing system. Initially, the first step is to replace the tubing system. A lightweight gypcrete/concrete lumber or pour should be installed. This will raise the floor by several inches. To be able to install the tubing system successfully it should be stapled underneath the subfloor. Since replacing procedures needs access under the surface, the flooring or ceiling should be removed and replaced. Important procedures are as follows:

1. Make a scale drawing of the floor to clearly see which part of the flooring systems need replacement and which parts do not.

2. Send the scale drawing to a provider. The provider will send back a layout and series of instructions for the installation. All materials will also be listed.

3. Contact a heating contractor so that all requirements are met.

4. Buy the necessary tubing systems and components.

5. Position all components as indicated in the instruction.

6. The system should be covered with tile adhesive or the floor’s material.
