system
The heating element is controlled by a
flow switch which means a DHC can never
dry-fire and fail prematurely. And since all
DHCs are hydraulically controlled, operation
is quiet. DHC water heaters are equipped
with a safety high-limit with manual reset.
The rugged all copper design ensures many
years of reliable service.
DHC 3-1, DHC 3-2 and DHC 4-2 models
are shipped with 0.5 GPM pressure
compensating flow reducer/aerators that
fit on most faucets. Flow controls and
faucet aerators are highly recommended in
conjunction with tankless water heaters. No
pressure relief valve, drains, or circulating
pumps needed.
