Radiant heat systems offer an efficient and comfortable way to heat your home. Unlike traditional heating methods that circulate warm air, radiant heat systems warm the floor and objects in a room, providing consistent and even heat distribution. This method not only enhances comfort but also improves energy efficiency and indoor air quality.
Ongaro & Sons specializes in providing top-notch radiant heat systems services. Whether you are considering installing or retrofitting a new system or need repairs on your existing setup, our skilled technicians are ready to assist you.

Benefits of Radiant Heat Systems
Installing a radiant heat system offers numerous benefits, making it an attractive choice for modern homes and buildings, as well as residents of older homes looking to retrofit their heating system to one with enhanced benefits.
One of the primary advantages is improved energy efficiency. Radiant heating directly warms surfaces and objects in a room, leading to more even heat distribution and lower energy consumption than traditional forced-air systems. This can result in significant cost savings on energy bills.

Installation Method: Suspended Tube Radiant Heat
Ongaro & Sons utilizes Pex-AL-Pex tubing in our hydronic systems, leveraging its capacity to withstand high water temperatures for an effective suspended tube system. The aluminum core of this tubing ensures structural integrity, preventing sagging between supports even at elevated water temperatures.
During installation, the tubing is strategically positioned within the space between floor joists, allowing it to radiate heat to surfaces within the joist cavity.
The tubing’s exterior also radiates heat to the surrounding air, promoting gentle convective circulation within the joist cavities. This circulation causes warm air to flow across the underside of the subfloor, enhancing heat transfer to the floor above.
Ongaro & Sons’ suspended tube systems offer several distinct advantages.
- They eliminate the need for heat dispersion plates, lowering installation costs.
- These systems function efficiently at high water temperatures under design load conditions.
- They can be connected directly to a boiler without a mixing valve.
Furthermore, suspending the tubing below the subfloor protects it from being punctured by nails used in hardwood flooring installation, so that future flooring upgrades won’t affect your radiant heat system.
