Straightforward tankless install, works well under multiple loads
Installation is straightforward for anyone with tankless experience, though the single exhaust pipe can cost more than the PVC used with condensing units. Gas lines must be properly sized for the high BTU rating, and hiring a professional is advised without direct gas line experience. Plumbing is simpler, especially with PEX. A built-in filter and softener cartridge helps reduce buildup, but annual vinegar flushing is still recommended. Running clothes, dishes, and a shower simultaneously caused no significant drop in water pressure or temperature. Parts and service are readily available, and the price is competitive with local hardware stores.
Pros
- + straightforward installation
- + built-in filter and softener cartridge
- + no pressure or temperature drop with multiple simultaneous uses
- + readily available parts and service
- + competitive price
Cons
- − single exhaust pipe can be pricier than PVC
- − requires properly sized gas lines
- − professional recommended for gas line work

Persistent Problems After Installation
This water heater has not worked properly since installation. It appears to time out and requires a reset every time hot water is needed. The manufacturer first suggested debris from installation in the pipe, then a faulty sensor. After replacing the sensor, two error messages (1 and 441) appear on reboot, and the in-use light only turns on after a reboot while the unit stays in standby mode. There is concern the motherboard may be the next issue.
Cons
- − times out
- − requires frequent resets for hot water
- − error messages 1 and 441 on reboot
- − in-use light only after reboot
- − stays in standby mode
- − possible motherboard failure

Great value boiler, installable with some DIY experience
This unit is essentially a Takagi 501 x3 series with a water filter. It costs about $1600 delivered, far less than a $9000 replacement quote. Installation is straightforward for anyone with basic DIY experience, though a concentric flue must be purchased separately. The manufacturer warns that professional installation is required to keep the limited warranty. The boiler works well and provides ample hot water. A similar unit in another property has remained reliable for years. The gas inlet valve issue from earlier models appears resolved.
Pros
- + great value
- + simple DIY installation
- + works well
- + reliable performance
Cons
- − concentric flue sold separately
- − warranty void without professional installation
