Case Study: Noritz Boilers and Bock Indirect Heaters Solve Rental Property Dilemma. A Switch from Oil to Gas Saves Money. 

Mick Jaeger owns rental property in Old Saybrook CT. A two unit building came with a heating issue: one oil fired boiler serving two apartments, and the high cost of heating oil. 

Chuck Appleby of Appleby Plumbing and Heating offered a solution. He installed two Noritz Model NH-1501-DV boilers ?one for each apartment. The domestic hot water is delivered by installing a 30 gallon Bock SideKick?indirect water heater as a circulator zone on each boiler. The boilers are sealed combustion and the DV kit provides fresh air intake and exhaust in a compact and neat package with two ports.

Each boiler is piped with a copper manifold built on site with Grundfos circulators for system and zone pumps wired to Taco Controls. Copper tubing is transitioned to Uponor PEX tubing between the floor joists and feed radiation in each apartment.
Mr. Jaeger is thrilled with the result. Each tenant receives a gas bill and the high efficiency of these systems also makes heating affordable.

Noritz has a complete line of Stainless Steel (Category III) Venting. Commercial tankless hot water heater installations are required by code to use stainless steel venting and we manufacture all the components necessary to meet those requirements. They offer a complete line of vertical and horizontal, 3", 4" and 5" venting for many applications.

Since 1929 Bock has been manufacturing a full line of quality-crafted, high-efficiency products, including oil-fired water heaters, gas-fired water heaters, dual-fuel water heaters, indirect coil tank water heaters, and glass-lined storage tanks. In 1955 Oscar Bock, company founder, invented the original multi-finned flue which was patented under the name of Turboflue?in 1960. Since then, their engineers have developed and utilized this notable achievement as a strong foundation for their water heaters.

In this project, two Bock SideKick?30 gallon indirect water heaters were installed. They feature C-glass? a durable and exclusive porcelain enamel glass which lines all tanks and coils. The lining is highly resistant to aggressive water and is not susceptible to damage due to the presence of chloride in the water. The Inner tank is hand-crafted from heavy gauge steel and the outer jacket is made from steel and is powder coated. These tanks also feature a 1-1/2?diameter coil. The larger diameter yields higher recovery and less pressure drop through the coil and the smooth surface resists lime build up.
