- Is this unit big enough for a whole house?
- At 199,000 BTU it is one of the larger residential tankless units and can typically run several fixtures at once. Very large homes with many simultaneous users may still need more than one unit.
- Does it need electricity to run?
- Yes. It uses a 120V AC power source for electronic ignition and controls, so a nearby outlet is required.
- Can it be installed outdoors?
- No. It is designed for indoor installation with direct venting.
- What gas pressure does it require?
- It needs natural gas supplied at 4 to 10.5 inches water column. A installer should verify pressure before commissioning.
- Does it include a recirculation pump?
- Yes, a pump is included, which helps deliver hot water to fixtures faster than a non-recirculating unit.
- Will it work with a standard 3/4-inch water line?
- Yes. The water connections are 3/4-inch NPT, which matches common residential plumbing.
