Hydraulic Heat

Hydraulic Heat

The installation process of a hydraulic (or hydronic) heating system typically involves the following steps:

System Design & Planning:

  • Assessment: Evaluate the home's layout, size, and insulation to determine the appropriate size for the boiler, pipes, radiators, or underfloor heating.

  • Component Selection: Choose the heat source (boiler, heat pump, or other), piping materials (typically PEX or copper), and type of heat delivery (radiators, baseboards, or in-floor tubing).

Piping and Distribution Setup:

  • Piping Layout : Plan and install the network of pipes that will carry the heated fluid throughout the home. This includes running pipes to radiators, underfloor systems, or baseboards.

  • Insulation : Insulate the pipes to ensure heat efficiency and prevent heat loss.

  • Connecting Radiators/Underfloor Heating : Install radiators, baseboard units, or lay the underfloor heating tubing, ensuring that they are properly connected to the piping network.

Thermostat and Controls Installation:

  • Thermostats : Install thermostats in key areas to control the temperature.

  • Zoning : If using multiple zones (rooms or areas with separate temperature control), install zone valves and additional thermostats to regulate the heating independently in each zone.

System Testing & Adjustment:

  • Test Functionality: Turn on the system and check for leaks, proper circulation, and uniform heat distribution.

  • Adjust Settings : Set the thermostats, adjust pump speeds, and make any necessary adjustments to optimize the system's performance.

Installing the Heat Source:

  • Boiler or Heat Pump: Install the heat source (typically in a utility room or basement). Boilers are connected to the water supply and electrical systems, while heat pumps may also be connected to a geothermal or air-source system.

  • Fuel Connection (if applicable): For gas or biomass boilers, connect the fuel source (gas line, pellet supply, etc.).

Installing Circulation Pumps:

  • Pump Setup: Install a circulation pump to ensure heated water or fluid flows through the pipes. The pump moves the fluid from the boiler/heat pump to the radiators or underfloor system.

  • Pressure Testing: Pressure test the entire system to ensure there are no leaks.

System Filling and Flushing:

  • Filling the System : Fill the system with water or an antifreeze solution, depending on the system's requirements.

  • Flushing : Flush the pipes to remove air pockets and debris, ensuring proper fluid circulation and efficient heating.

Final Checks & Clean-Up:

  • Inspection: Inspect the installation for safety, code compliance, and operational efficiency.

  • Clean-Up: Clean up the installation area and ensure all components are properly sealed and secured.

Once installed, the hydraulic heating system should provide consistent, energy-efficient warmth throughout the home. Regular maintenance and system checks will help maintain its efficiency over time.
