Bosch Thermotechnology, Watertown, Massachusetts, introduces two additions to its electric tankless water heater lineup. Bosch’s new Tronic 4000 C (pictured) is ideal for point-of-use, under-sink installations, while the Tronic 6100 C is ideal for whole-house applications. The Tronic 4000 C measures only 8.5-inches by 13-inches and weighs 4.4 pounds. It can be wall-mounted directly under the sink and requires no venting.
The Tronic 4000 C comes in four model options: 3.5 kW, 6.5 kW, 8.5 kW and 10.5 kW. The Tronic 6100 C features a stainless-steel canister inside the unit, which heats up the water but doesn’t store water like a traditional tank water heater. It measures 13 1/4-inches by 20 1/4 -inches and comes with 3/4-inch NPT fittings for both cold and hot water connections.
