RHT Spartan Prefab 1-Zone Electric Boiler Panels

Fully Modulating Boiler with Outdoor Reset

Radiant Heating Technology (RHT) Pre-Plumbed Panels are professionally engineered, manufactured and pressure-tested. Each panel comes complete with boiler, expansion tank and Grundfos UPS15-58FRC 3-speed pump. Panels are designed around the reliable Thermolec TMB Mini Boiler with H Stamp.

Choose from three boiler sizes and a variety of manifold options. All components are securely attached to an aluminum panel, ready to be mounted and connected to your hydronic heating system. Panel size varies depending upon number of pumps, but typically they measure 36" wide x 36" high x 12" deep. RHT Pre-Plumbed Panels are an excellent value and problem-solver. They will enhance the appearance of your installation while decreasing the labor and expense required to complete your radiant project.
