For almost 70 years Amtrol has continued to roll out top of the line HVAC technology. The HM indirect-fired water heater is the perfect example of the innovation they continue to provide. With advanced control technology paired with undeniable reliability, HM's modern design is unique as well as efficient. By using your home's boiler energy, HM reduces fuel cost while maximizing hot water output. There is no flame, flue, or fuel lines giving you the freedom to install almost anywhere, and a triple shelled tank ensures strength and longevity. A Hi-Delta heat exchanger provides performance from optimal coil spacing, and is removable for easy cleaning and service. Equipped with a relief valve, blowdown tube, heat trap, and Turbulator Dip Tube to reduce sediment build-up, there is no doubt that the HM is "Efficiency at its Best".
Bimodal HDPE Poly Bottle
A high density polyethylene (HDPE) bottle is corrosion-proof and provides fresh, clean water, while resisting chlorides, scale, or aggressive water.
Unique Molded Insulation
The HM has reaction injection molded (RIM) insulation which enhances efficiency by eliminating gaps that lead to heat loss.
Deep Drawn Steel Construction
Deep drawn steel has twice the strength of regularly used steel construction while a Tuf-Kote HG finish repels harsh or damp environments.
Bottom Mounted Drain Valve
A pre-installed bottom mounted drain valve completely empties the tank while a sediment trap captures and flushes debris that would otherwise be left in the tank.
Hi-Delta Heat Exchanger
Both energy efficient and scale resistant, the Hi Delta heat exchanger is designed with optimal coil spacing for performance, and is removable for easy cleaning.
