Honeywell has introduced a new hydronic zoning panel line for pumps and zone valves.
New with the HPSR (pump) and HPZC (zone valve) panels:
- “C” common terminal for each thermostat. This allows simple connections for Wi-Fi stats requiring a common wire.
- Compatible with most thermostats including power-stealing and electro-mechanical. This makes your installation more flexible.
- LED status indicator lights visible with the cover on or off. This saves troubleshooting time.
- Color coded wiring. This increases installation speed and decreases the chance of errors.
- 5 year warrantee. Backed by Honeywell’s history of proven performance and product support.
All these features and benefits at a more competitive price than previous hydronic zone panels!
TEC/NEC will be stocking the HPSR101 (1 zone), HPSR103 (3 zone), HPSR104 (4 zone) & HPSR106 (6 zone) pump relays. The HPZC106 6 zone valve relay will also be in stock.
Installing a thermal expansion tank with a new water heater has become increasingly important. Most cities nowadays have check valves in their water meters which prevent the home’s water from going back into the public water system. While this process poses a health benefit, it creates a problem for the domestic water system.
The check valves make the domestic water system in a house a “closed system.” This means that when the water in the water heater is heated, it expands but has nowhere to go. It therefore increases the pressure in the domestic water system, potentially causing damage and leaks to the system. See attached brochure from Bradford White for more details.
There exists a simple solution: to install a thermal expansion tank on the cold water inlet of the water heater. Sizing is also simple: use a HWTX5 tank for 40 & 50 gallon water heaters. For water heaters above 50 gallons, use a HWTX12 tank. Expansion tanks are cost-effective and easy to install with a new water heater.
Modern boiler applications call for technology that is innovative, flexible and adaptable. KN Series cast iron boilers were purposefully engineered to live up to today’s toughest applications and challenges, providing versatility in boiler system configuration and installation without sacrificing the bottom line.
In this day and age, the word ‘hybrid’ gets thrown around often. But what about the terms ‘base load’ or ‘mixed-boiler? Within the commercial boiler market, the concept behind these configurations is simple, lower the upfront equipment cost of a complete condensing boiler plant by incorporating new units into an existing and less expensive non-condensing boiler plant.
With a hybrid boiler system that combines KN Series condensing boilers within an existing, non-condensing boiler plant, operators are able to meet total BTU requirements while optimizing overall system performance, increasing boiler efficiency under various climate, seasonal and load conditions. By operating during most of the heating season, the condensing KN Series units provide the bulk of the high-efficiency BTU output when loop temperatures are low, while the existing and less-efficient non-condensing units act as supplemental boilers when outdoor temperatures fall and boiler loop temperatures increase.

TEC introduces a new commercial boiler line to our offering – KN from Advanced Thermal Hydronics (ATH).
Engineered to meet the demands of today’s commercial condensing boiler market, KN Series by Advanced Thermal Hydronics (ATH) are high efficiency condensing gas boilers built with the historically recognized reliability and strength of cast iron. As the first line of commercial boilers capable of realizing the full potential of cast iron, KN Series boilers take the heat-retention and durability of cast iron and couple it with the energy savings of fully modulating, highly efficient condensing boiler performance.
Capable of adapting to changing operating environments while generating 200,000 – 3,000,000 BTUs, KN Series boilers deliver environmentally friendly solutions for a wide range of boiler applications, all the while maintaining low fuel utilization and a small footprint. All KN Series models come equipped with HeatNet 3.0 boiler control software for precise system control through digital communication, and even have the option of remote monitoring through HeatNet Online.
Significant reductions in energy consumption, when coupled with low NOx and CO2 emissions, make KN Series’ complete line of cast iron, condensing gas boilers an environmentally friendly, cost-effective option that will last for years to come.
