Rural Energy Enterprises: Anchorage's Trusted Ergomax Heat Exchanger Supplier.
Rural Energy stocks the Ergomax E23 Heat Exchanger in Anchorage, available for pickup at our Arctic Spur Rd location or shipped statewide. The E23 delivers instantaneous domestic hot water and space heating from a single boiler connection, with 99% heat transfer efficiency and no storage tank recovery time required.
What Is the Ergomax E23 and What Does It Do?
The Ergomax E23 is a high-efficiency indirect heat exchanger designed for residential and light commercial hydronic heating systems. It connects to your existing boiler and performs three functions simultaneously: it delivers instantaneous domestic hot water on demand, distributes heat to space heating circuits (baseboard, radiant floor, or fan coil), and buffers the boiler to prevent short cycling that degrades performance and shortens boiler life.
In Alaska, this matters. Most homes with hydronic heating systems run a single boiler that needs to serve both domestic hot water and space heating. The E23 handles that integration cleanly, without requiring a separate water heater and without the standby heat loss of a storage tank. Water is heated on demand as it passes through the heat exchanger, using the boiler loop as the heat source.
The E23 is suitable for boilers with output up to approximately 200,000 BTU, covering most residential and small commercial applications in Anchorage. Its double-wall construction is double-wall exempt, meaning it meets code requirements for indirect water heater installations without requiring a separate double-wall separation in most jurisdictions.

Applications in Alaska
Residential Hydronic Systems
The E23 is designed for homes with boiler-based heating. It accepts heat from your boiler loop and delivers it to your domestic hot water and space heating distribution without allowing the fluids to mix. This protects your boiler from potable water contamination and allows your heating zones to operate at different temperatures from a single heat source.
Baseboard and Radiant Floor Heating
The E23 integrates directly with baseboard radiation and in-floor radiant systems. Its high output temperature rating (to 190°F) means it can serve older high-temperature baseboard systems as well as lower-temperature radiant floor setups depending on boiler configuration.
Boiler Protection and Buffering
Modern high-efficiency condensing boilers are sensitive to short cycling, rapid on/off cycles caused by low-mass heating loads. The E23's 26-gallon tank volume provides thermal mass that buffers these loads, reducing cycle frequency and extending boiler life. This is a meaningful consideration in Alaska, where heating season is long and boiler reliability is critical.
Small Commercial
The E23's capacity (boilers to 200,000 BTU, flow to 1,800 gph) makes it suitable for small commercial applications including workshops, remote lodges, small commercial buildings, and bush community facilities where boiler-based heating is common.
